병을 “와이드 마우스(광구)”로 만드는 요인과 성형이 어려운 이유
A wide mouth jar is defined by geometry, not by marketing language. In blow molding the controlling dimension is the neck-to-body diameter ratio, which is the finished neck opening diameter divided by the maximum body diameter of the container. A wide mouth jar carries a neck-to-body diameter ratio above 0.5, with the typical production window sitting between 0.55 and 0.85. By contrast a narrow neck bottle stays below 0.35, and many pharmaceutical dropper and beverage bottles sit well under 0.25. The moment the ratio climbs past 0.5 the part stops behaving like a bottle and starts behaving like a small open container, and that single change rewrites the way the parison must be formed, blown and ejected.
Wide mouth jars are produced across a broad range of opening sizes and volumes. The most common neck or finish diameters are 38 mm, 45 mm, 53 mm, 63 mm, 70 mm, 89 mm and 100 mm. Matching volumes usually run from 30 mL for sample and lab jars up to 1000 mL for food, confectionery and pet food containers. A 100 mm opening on a 1000 mL jar is at the upper edge of practical injection blow molding, while a 38 mm opening on a 120 mL jar is at the easy end of the range. The table below places these sizes on a single reference grid so the geometry is unambiguous before we discuss process behavior.
| Opening diameter (mm) | Typical volume range (mL) | Neck-to-body ratio | Common use |
|---|---|---|---|
| 38 | 30 – 250 | 0.55 – 0.70 | Sample jars, cosmetic cream cups, vitamin packs |
| 45 | 50 – 300 | 0.55 – 0.72 | Personal care, single-dose food |
| 53 | 100 – 400 | 0.58 – 0.75 | 화장품, pharmacy powder |
| 63 | 150 – 500 | 0.60 – 0.78 | Honey, sauce, supplement jars |
| 70 | 200 – 750 | 0.62 – 0.80 | Jam, nuts, body butter |
| 89 | 400 – 900 | 0.70 – 0.83 | Pet food, confectionery, lab storage |
| 100 | 500 – 1000 | 0.75 – 0.85 | Large food, protein, industrial samples |
넓은 입구 용기가 좁은 목 병보다 성형하기 어려운 이유는 단일 결함이 아니라 네 가지 결합된 기계적 및 공정 원인입니다. 이 네 가지 원인을 이해하는 것은 이 기사에서 나중에 논의되는 모든 솔루션의 기초입니다.
First cause: the blow-up ratio is locked down. In blow molding the blow-up ratio is the body diameter divided by the parison diameter at the point being blown. A narrow neck bottle is injected as a slim parison and blown outward many times, so the polymer stretches dramatically and fills the cavity. A wide mouth jar already starts with a parison that is nearly as wide as the final body, because the neck finish itself is wide. The available blow-up ratio collapses to roughly 2.0 to 3.5, sometimes less. With little stretch left, the polymer cannot redistribute itself to even out wall thickness, so the base and shoulder tend to stay thin while the body stays thick. This is the root of most wall balance complaints on wide mouth parts.
Second cause: the parison distribution is difficult to make uniform. Because the part is short and squat, the parison travels a short distance from the injection cavity to the blow cavity, but the cross-section changes are abrupt. The neck region must stay stiff and dimensionally exact, the shoulder must accept rapid expansion, and the base must fill without webbing. A uniform tubular parison that works for a tall bottle does not map onto a wide mouth jar, so the parison wall must be deliberately profiled along its length.
Third cause: the demolding path is obstructed. A narrow neck bottle is stripped off the core rod through a small opening, so the draft is gentle and the undercut risk is low. A wide mouth jar has a large opening and large side walls with threads or knurls, so the stripping travel is long and the friction against the core rod and cavity is high. The part wants to stick, gall, or stretch during ejection, and a single bad release can scar the sealing land.
Fourth cause: the neck lacks rigidity and deforms easily. The wide neck is both the largest opening and the most functionally critical surface. It carries the threads or snap feature, the sealing plane, and the torque load of the closure. Because the neck wall is necessarily thin relative to its diameter, it cools slowly and, if ejected while soft, relaxes into ovality or sink. A warped neck leaks, a low-torque neck cross-threads, and an out-of-round neck fails automated capping.
광구 병이 어려운 이유는 특정 단계 하나가 실패하기 때문이 아니라, 블로우업 비율, 파리슨 프로파일, 이형 경로 및 목 강성이 동시에 서로 상충하기 때문입니다. 사출 블로우 성형은 이 네 가지를 동시에 가장 잘 제어할 수 있는 공정입니다.
Aibim is a Wanplas factory with more than twelve years of experience building injection blow molding machines and molds, exporting to over forty countries, with its own CNC machining center and an annual capacity above one hundred lines per year. The wide mouth jar is one of the most demanding parts that an IBM line is asked to make, and the rest of this guide explains how to design the process, the mold and the material so the part consistently passes spec.
광구 용기용 IBM vs ISBM vs EBM
Three blow molding routes can technically produce a wide mouth jar: injection blow molding (IBM), injection stretch blow molding (ISBM), and extrusion blow molding (EBM). They differ most at the neck finish, where the wide mouth jar lives or dies. The comparison below is a process-to-process benchmark, not a brand comparison, and it shows why IBM dominates precision wide mouth production.
| Attribute | 사출 블로우 몰딩 (IBM) | 사출 Stretch 블로우 몰딩 (ISBM) | Extrusion 블로우 몰딩 (EBM) |
|---|---|---|---|
| Neck finish precision | Plus or minus 0.05 mm, no flash, no trim | Plus or minus 0.10 mm, no flash | Plus or minus 0.30 mm, flash requires trim |
| Minimum practical neck-to-body ratio | 0.50 and up (best for wide mouth) | 0.45 and up | 0.30 and up (best for very wide, low-precision) |
| Wall thickness uniformity | Good, controllable by parison profile | Excellent, biaxial orientation | Fair, parison programming needed |
| Material adaptability | PE, PP, PS, SAN, PC, PCTG, TPU | PET, PETG, PEN, some PP | PE, PP, PVC, PC, TPU |
| Scrap rate | Low, below 5 percent | Low, below 5 percent | Medium, flash and trim 15 to 25 percent |
| Cycle time | Medium | Medium | Medium |
| Mold complexity | Medium | Medium to High | Low |
| Cost level | Medium | Medium to High | Low |
The decisive column for a wide mouth jar is neck finish precision. The neck is the opening through which the product is filled and the closure is applied, and on a wide mouth jar that opening can be 100 mm across. IBM forms the neck by injecting molten polymer into a precision neck ring, so the threads, the sealing land and the inside diameter are fixed by steel, not by a cut parison. That yields a finish held to roughly plus or minus 0.05 mm with no flash and no secondary trimming operation. ISBM is excellent for oriented PET and gives the best wall distribution, but its neck precision and its material set (driven by PET and PETG) make it a second choice for PP and PS food jars. EBM is the cheapest route and handles very large openings, but the flash line and the plus or minus 0.30 mm neck tolerance force a trimming step and a looser closure fit, which is unacceptable for many food, pharmaceutical and cosmetic jars.

6가지 핵심 과제와 해결책
다음의 여섯 가지 문제는 광구 병 프로그램에서 가장 자주 발생하는 문제들입니다. 각각은 현상, 메커니즘, 파라미터 또는 구조 대책, 검증 방법의 루프로 작성되었습니다. 현장에서 추측 대신 이 구조를 사용하여 불량 부품을 진단하십시오.
과제 1: 블로우업 비율 한계로 인한 바닥 및 어깨 벽 두께 불균형
현상. 몸체 벽은 공차 내로 측정되지만 베이스는 낙하 테스트에서 찢어질 만큼 얇고, 어깨는 목으로의 전환부 근처에서 국부적인 얇아짐을 보여줍니다. 부품은 1.2m 낙하 또는 상부 하중 테스트에서 실패하기 전까지는 정상으로 보입니다.
Mechanism. The wide mouth geometry leaves only a 2.0 to 3.5 blow-up ratio. With little radial stretch available, the polymer cannot flow from the body into the base and shoulder during blowing. Where the parison was already thin, it stays thin; where it was thick, it stays thick. The classic symptom is a thick cylindrical body and a starved base.
Parameter and structure countermeasure. Profile the parison deliberately with a stepped core rod so the wall thickness tapers from the neck down to the base. A practical injection wall gradient runs from 1.5 mm at the neck region to 4.5 mm toward the base, putting more material where the blow-up ratio is lowest. Keep the blow-up ratio inside the 2.0 to 3.5 window by sizing the core rod diameter correctly, and apply a staged pre-blow: a low first pressure to seat the parison against the cavity, then a higher second pressure to complete the form. Avoid trying to compensate by raising blow pressure alone, which only bursts weak zones.
Verification method. Cut the jar at eight or more points (neck, shoulder, upper body, mid body, lower body, base radius, base center, side wall) and measure wall thickness. Confirm the thinnest point is above the drop-test minimum and that the ratio between the thickest and thinnest wall is inside the agreed spec. Re-run the drop test at 1.2 m full before releasing the setting.
과제 2: 넥 변형 및 타원도
현상. 목 개구부가 도면 허용치보다 더 진원도를 벗어나거나, 실링 랜드에 가시적인 싱크가 나타납니다. 캡이 나사산을 잘못 타거나 토크 테스트에서 누수가 발생합니다.
Mechanism. The wide neck wall is thin relative to its diameter and has a large surface area, so it cools more slowly than the body. If the part is stripped while the neck polymer is still soft, the land relaxes under its own weight and the clamping load, producing ovality and sink. Low crystallinity control in PP makes the effect worse because the amorphous skin is soft at higher temperatures.
Parameter and structure countermeasure. Give the neck ring its own independent cooling circuit so the neck can be brought to temperature faster than the body. Control neck crystallinity by holding the neck ring temperature in the correct band for the grade. Keep the demold temperature below 70 degrees C for polypropylene. Extend the residence time on the turret at the blow or cooling station so the neck sets before transfer. Add 0.2 to 0.5 mm to the neck wall thickness compared with a narrow neck design to raise its stiffness without changing the opening.
Verification method. Measure neck inside diameter at two perpendicular axes with a bore gauge and compute ovality as the difference. Run a torque test with the production closure at the specified application torque and confirm no cross-thread and no leak under the seal test. Check the sealing land with a flatness indicator referenced to the datum plane.
과제 3: 탈형 어려움과 표면 긁힘
현상. 용기 본체나 목에 세로 방향 스크래치 자국이 나타나거나, 코어 로드에 달라붙어 취출 로봇이 부품을 놓칩니다. 사이클 안정성이 떨어지고 스크랩이 증가합니다.
Mechanism. A wide mouth jar has a large internal surface dragged along the core rod during stripping, and the threads or knurls add local undercut. The release travel is long, so friction is high and any sticking point galls the surface. A 0.5 degree draft angle that works on a bottle is insufficient here.
Parameter and structure countermeasure. Increase the draft angle to 1 to 2 degrees, roughly double the bottle norm. Use a stripper air pulse with a timed sequence so a short burst of compressed air breaks the vacuum seal at the start of ejection. Add a mechanical stripper plate that pushes the jar uniformly off the core rod instead of relying on air alone. Polish the cavity and core rod to a surface finish of Ra 0.2 micrometer or better so the polymer does not grip. Use a release agent only when absolutely necessary and only in a controlled, documented dose, because excess agent blooms to the surface and spoils printing or labeling.
검증 방법. 연속적인 사이클 블록을 실행하고 스티킹 또는 스코어링 이벤트를 세십시오. 비스듬한 빛 아래에서 내부 벽을 검사하여 스코어 라인을 확인하십시오. 테이크아웃 로봇이 블록 전체에서 놓친 스트로크 없이 모든 부품을 집어 올리는지 확인하십시오.
과제 4: 낙하 균열과 함께 발생하는 어깨 및 모서리 얇아짐
현상. 병은 초기 검사를 통과하지만 충전, 적재 또는 운송 중에 어깨 부분이나 내부 모서리에서 균열이 발생합니다. 파손 원인은 얇고 응력이 높은 모서리입니다.
메커니즘. 날카로운 내부 모서리는 응력을 집중시키고 얇은 숄더는 충격 에너지를 흡수할 수 없습니다. 코어 로드가 너무 차가우면 파리슨이 형태를 갖추기 전에 동결되고, 너무 뜨거우면 파리슨이 처집니다. 잘못된 등급은 사용 온도에서 낮은 충격 강도를 제공합니다.
Parameter and structure countermeasure. Run the core rod with zoned temperature control, typically 60 to 110 degrees C, so the parison stays formable long enough to fill the corners. Specify corner radii of R 2 mm or larger at every internal transition so stress does not concentrate. Choose a material with enough low-temperature impact, for example a polypropylene random co-polymer for improved toughness. Where the application allows, apply a short anneal step after molding to relax residual stress in the shoulder and corners.
검증 방법. 어깨와 모서리를 절단하여 반경이 도면을 충족하는지 확인하십시오. 정격 용량으로 채운 병으로 1.2m에서 요구되는 각 충격 방향에 대해 낙하 테스트를 수행하고, 시장이 저온 성능을 요구하는 경우 냉각 컨디셔닝 사이클 후 반복하십시오.
과제 5: 긴 사이클 타임 및 낮은 생산량
현상. 캐비티당 사이클이 상업적 목표보다 길어서, 전체 캐비티 가동에도 연간 생산량이 사업 계획에 미치지 못합니다.
메커니즘. 광구 병은 동일한 부피의 병보다 캐비티당 더 많은 플래튼 면적을 차지하므로 캐비티 수는 샷 크기가 아닌 플래튼에 의해 제한됩니다. 두꺼운 목과 바닥이 열을 보유하므로 냉각이 느리고, 터렛은 스테이션 간 이동에 빈 시간을 소비합니다.
Parameter and structure countermeasure. Select a multi-cavity configuration that fits the platen, accepting that wide mouth jars rarely reach the cavitation of narrow neck programs. Drop the cooling water temperature to 8 to 15 degrees C and densify the water channels so heat leaves the mold faster. Use a servo-driven turret to shorten the non-productive transfer time between stations. Optimize the dry cycle by tightening the clamp open, transfer and close sequence without sacrificing safety.
| Cycle phase | Typical time (s) | Optimization lever |
|---|---|---|
| 사출 and parison hold | 1.4 – 2.2 | Balance pack pressure, avoid over-pack |
| Transfer to blow station | 0.4 – 0.7 | Servo turret, shorten dead stroke |
| Blow and cooling | 2.0 – 4.0 | Water at 8 to 15 C, denser channels |
| Transfer to eject station | 0.4 – 0.7 | Servo turret timing |
| Demold and reset | 0.8 – 1.4 | Stripper plate, stripper air timing |
| Dry cycle total | 3.8 – 5.0 | Machine dependent |
검증 방법. 안정적인 생산 블록 동안 실제 성형 사이클을 측정하고 각 단계를 위 표와 비교하십시오. 이송 단계가 아닌 냉각 단계가 병목인지 확인하십시오. 이송이 지배적이라면 개선 효과는 더 차가운 물이 아닌 서보 터렛에서 얻을 수 있습니다.
과제 6: 실링 면 평탄도 및 마개 결합
현상. 용기가 정적 누수 테스트를 통과하지만 열 사이클, 적층 또는 운송 후 누수가 발생하거나, 클로저가 림 주변에 불균일한 토크를 가합니다.
Mechanism. A wide mouth jar has a large sealing face, so a small absolute warp becomes a large leak path. Warp comes from uneven cooling across the wide land, from residual stress, and from a neck that was not fully set at demold. A mismatch between the thread form and the closure compounds the problem.
Parameter and structure countermeasure. Hold the seal face flatness to 0.15 mm or better by balancing the neck ring cooling and by gating the parison so the land fills symmetrically. Select the thread form to match the closure family: the 400, 415 and 425 series are the common continuous-thread finishes, and the choice sets the wall and torque behavior. For products needing a secondary barrier, design the land to accept an inner plug or an aluminum foil seal without distorting the plane. Validate the closure torque against the chosen finish so the cap seats uniformly.
검증 방법. 화강암 기준면에서 다이얼 게이지로 밀봉면 평탄도를 측정하십시오. 충전되고 캡이 씌워진 병에 진공 또는 압력 유지 테스트를 수행한 다음 열 사이클 후에 반복하십시오. 적용 토크가 모든 샘플링 단위에서 합의된 범위 내에 있는지 확인하십시오.
광구 용기용 재료 선택
Material choice sets the ceiling on clarity, impact, temperature resistance and food contact compliance. The table below lists the materials that run on IBM and ISBM wide mouth programs with their processing window and compliance reference. Compliance names are given as plain text for verification against the official regulation text.
| Material | Melt temp (C) | Mold temp (C) | Demold temp (C) | Shrinkage (%) | Impact grade | Transparency | 식품 contact compliance |
|---|---|---|---|---|---|---|---|
| PP homo-polymer | 210 – 250 | 20 – 60 | < 70 | 1.5 – 2.0 | Medium | Opaque | FDA 21 CFR 177, EU 10/2011 |
| PP random co-polymer | 200 – 240 | 20 – 60 | < 70 | 1.4 – 1.9 | High | Opaque, slight clarity | FDA 21 CFR 177, EU 10/2011 |
| HDPE | 200 – 240 | 15 – 50 | < 65 | 1.5 – 2.5 | Medium-High | Opaque | FDA 21 CFR 177, EU 10/2011 |
| PS | 190 – 230 | 20 – 50 | < 60 | 0.4 – 0.7 | Low | High | FDA 21 CFR 177, EU 10/2011 |
| SAN | 220 – 260 | 50 – 80 | < 70 | 0.4 – 0.7 | Medium | High | FDA 21 CFR 177, EU 10/2011 |
| PET (ISBM) | 270 – 290 | 90 – 120 | < 90 | 0.2 – 0.5 | High | Very high | FDA 21 CFR 177, EU 10/2011 |
| PETG | 230 – 260 | 20 – 40 | < 65 | 0.3 – 0.6 | High | Very high | FDA 21 CFR 177, EU 10/2011 |
| PCTG | 240 – 270 | 30 – 60 | < 70 | 0.4 – 0.7 | Very high | Very high | FDA 21 CFR 177, EU 10/2011 |
| PC | 280 – 320 | 80 – 120 | < 100 | 0.5 – 0.7 | Very high | High | Check BPA compliance for baby-related items |
폴리프로필렌 in homo-polymer or random co-polymer grade is the default for food jars such as jam, honey, nuts and confectionery because it resists heat, chemicals and grease while meeting food contact rules. The random co-polymer adds low-temperature impact, which helps jars that are filled hot or stored cold. HDPE serves pharmaceutical powder and tablet jars where squeezability and chemical resistance matter more than clarity. PS 및 SAN give transparent display jars for cosmetics and hardware, though their impact is lower so the wall must be tuned for drop performance. PET and PETG through ISBM produce the clearest wide mouth jars with the best barrier, but they need the higher stretch ratios and the hotter mold that ISBM provides. PCTG and PC deliver top impact and clarity for demanding items; for any baby-related product the PC grade must be verified for BPA compliance before use.
광구 IBM용 금형 설계 원칙
금형은 네 가지 난이도 원인이 강철로 해결되는 곳입니다. 광구 IBM 금형은 병 금형과 세 가지 구조적 측면에서 다릅니다: 터렛 레이아웃, 넥 링 구조 및 코어 로드 강성.
Three-station and four-station turret layout. Aibim IBM machines use a three-station one-step process: injection, blow and ejection on a rotating turret. Some programs add a fourth station for extra cooling or in-mold labeling. A wide mouth mold occupies more platen area per cavity than a bottle mold, so the turret pitch and the platen size set the maximum cavity count directly. Plan the cavitation from the platen drawing, not from the shot size, because the wide body almost always runs out of platen before it runs out of polymer.
Neck ring split design and flash control. Because IBM injects the neck, the neck ring is a split steel insert that defines the finish. For a wide mouth jar the neck ring is large and must part cleanly without a flash line on the sealing land. Design the parting line away from the seal face, and hold the neck ring as a replaceable insert so wear does not force a full mold rebuild. Flash on the land is the fastest way to fail a closure leak test, so the neck ring fit is cut tighter than on a bottle mold.
Core rod length-to-diameter ratio and rigidity. The core rod forms the internal shape and carries the parison between stations. A wide mouth jar needs a large-diameter core rod, and a large-diameter rod is more prone to deflection than a slim bottle rod. Keep the rod aspect ratio conservative, support it at both ends where the machine allows, and specify a stiff, dimensionally stable grade so the inside diameter stays round across the run. A deflecting rod produces an out-of-round inside wall that no blow setting can fix.
Water channel layout and uniform temperature. Wide mouth jars need the neck cooled faster than the body, so the neck ring gets its own circuit while the body cavity gets another. Lay the channels to hold the mold temperature uniform within plus or minus 2 degrees C across the cavity face; a 5 degree C spread across a wide land is enough to warp the seal plane. Denser channels near the base and shoulder pull heat from the thick sections that otherwise dictate the cycle.
Mold material and maintenance. Use pre-hardened tool steel (P20-type) for the body and cavity where the loads are moderate, and stainless tool steel (420-type) for necks and cores that contact food-grade or corrosive compounds and need corrosion resistance with a polish-ready surface. The cavity and core rod are finished to Ra 0.2 micrometer or better for clean demolding. With routine cleaning, channel descaling and rod inspection, a well-built wide mouth IBM mold runs a long life; schedule a full refurbish at the cavitation and wear interval defined in the mold maintenance plan rather than waiting for a failure.
품질 검사 및 합격 기준
광구 용기는 치수, 기계적, 밀봉 기준에 따라 승인됩니다. 아래 표는 각 점검을 한계값과 방법에 매핑한 즉시 사용 가능한 승인 체크리스트입니다.
| Check | 수락ance limit | Method |
|---|---|---|
| Capacity | Plus or minus 2 percent of rated volume | Fill to overflow, weigh or measure |
| Neck inside diameter | Per drawing, plus or minus 0.05 mm | Bore gauge at two axes |
| Neck ovality | Below drawing max, typically < 0.10 mm | Two-axis bore gauge |
| Seal face flatness | 0.15 mm or better | Dial indicator on datum |
| Wall thickness distribution | Minimum at or above spec, 8 plus points | Section and micrometer |
| Vertical top load | Per rated stack load in newtons | Compression test at set speed |
| Drop test | No leak or break at 1.2 m, full | Drop on required orientations |
| Seal retention | Hold vacuum or pressure per spec | Vacuum or pressure chamber |
| Light transmittance and haze | Per clarity grade for transparent jars | Haze meter or spectro |
Capacity is confirmed by filling the jar to the overflow line and weighing the contents against the rated volume, with the tolerance held to plus or minus 2 percent so filling lines stay accurate. Neck inside diameter and ovality are checked at two perpendicular axes because a wide mouth jar fails capping the moment the opening goes out of round. Seal face flatness is the single most important number for leak performance and is held to 0.15 mm or better. Wall thickness is measured at no fewer than eight points so a thin base or shoulder cannot hide in a single reading. Top load in newtons confirms the jar survives pallet stacking, and the 1.2 m full drop test confirms field performance. Transparent jars are additionally checked for light transmittance and haze so the display appearance is controlled.
광구 용기 생산용 Aibim 기계
When the technical discussion reaches the question of which machine to run, Aibim offers a focused IBM lineup built for precision hollow parts including wide mouth jars. Two representative models are described below with specification tables that include the two numbers that matter most for this application: maximum bottle mouth diameter and maximum bottle volume.
Aibim IBM75 사출 블로우 성형기
The IBM75 is the largest standard Aibim model and the natural choice for wide mouth jars up to 1000 mL and openings up to 120 mm. Its single-crossbeam, double-pole clamping framework enlarges the mold setting space, which is exactly what a wide mouth mold needs because the body footprint is large. The machine uses Aibim PREFILL technology with a variable displacement pump that cuts energy use by at least 35 percent compared with a conventional fixed-pump hydraulic unit.
| Specification | IBM75 value |
|---|---|
| Clamping force | 75 tf (750 kN) |
| 사출 capacity (shot) | 600 cm3 |
| Screw diameter | 45 mm |
| L/D ratio | 20:1 |
| Maximum cavities | Up to 8 for small parts; 2 to 4 for wide mouth jars |
| Maximum bottle mouth diameter | 120 mm |
| Maximum bottle volume | 1000 mL |
| Platen size | 520 x 520 mm |
| Installed power | 30 kW |
| 건조 사이클 시간 | 4.5 s |
Aibim IBM65 사출 블로우 성형기
The IBM65 sits one step below the IBM75 and covers wide mouth jars up to 750 mL and openings up to 100 mm. It is the workhorse for food, cosmetic and pharmaceutical jars in the mid-volume band, with the same three-station one-step process and the same neck precision. Cavity count for a wide mouth jar is limited by platen space, so a 250 mL jar at 70 mm mouth can run four to six cavities while a 750 mL jar at 100 mm mouth runs two.
| Specification | IBM65 value |
|---|---|
| Clamping force | 65 tf (650 kN) |
| 사출 capacity (shot) | 450 cm3 |
| Screw diameter | 40 mm |
| L/D ratio | 20:1 |
| Maximum cavities | Up to 6 for small parts; 2 to 3 for wide mouth jars |
| Maximum bottle mouth diameter | 100 mm |
| Maximum bottle volume | 750 mL |
| Platen size | 460 x 460 mm |
| Installed power | 25 kW |
| 건조 사이클 시간 | 4.0 s |
Aibim also offers the IBM55 Hybrid Electric model for smaller wide mouth jars up to 500 mL and openings up to 80 mm, where the electric clamp and servo plasticizing give the tightest energy and repeatability numbers for cleanroom and pharmaceutical use. All three models share the Aibim advantages: CE-certified safety with a stripper station laser sensor and light curtain, SD-card recipe storage that moves a proven setting from one machine to another, and the Wanplas group backing for service and spare parts.

요구 사항-모델 선택 가이드
아래 표는 고객 요구 사항을 권장 Aibim 모델 및 캐비티 구성에 매핑합니다. 캐비티 수는 넓은 입구 금형에 대해 제공되며 앞서 설명한 플래튼 제한 레이아웃을 가정합니다. 최종 캐비테이션은 금형 설계 단계에서 확인됩니다.
| Mouth diameter | Volume | Material | Annual output | Recommended model | Cavities | Key configuration |
|---|---|---|---|---|---|---|
| 38 – 45 mm | 30 – 150 mL | PP / PS | Low to medium | IBM55 Hybrid | 4 | Electric clamp, cleanroom option |
| 53 – 63 mm | 100 – 300 mL | PP / HDPE | Medium | IBM65 | 4 | Independent neck cooling |
| 63 – 70 mm | 200 – 500 mL | PP / PETG | Medium to high | IBM65 or IBM75 | 3 – 4 | Stepped core rod, stripper plate |
| 70 – 89 mm | 400 – 750 mL | PP | Medium to high | IBM75 | 2 – 3 | Dense cooling, servo turret |
| 89 – 100 mm | 500 – 1000 mL | PP | Medium | IBM75 | 2 | 120 mm max mouth, reinforced core rod |
| Up to 100 mm | 250 – 500 mL | PET / PETG (ISBM) | High | Wanplas ISBM line | Per project | Oriented clarity, barrier |
For projects that need an oriented PET or PETG wide mouth jar with maximum clarity and barrier, the Wanplas group supplies the matching ISBM line so the customer stays with one supplier and one service organization. For any configuration outside the table, Aibim engineers size the machine from the part drawing, the annual volume and the material data sheet rather than from a generic rule.
서비스, 지원 및 시작 방법
광구 병 라인 구매는 일회성 거래가 아니라 생산 관계의 시작입니다. Aibim은 Wanplas 공장으로서 모든 기계에 그룹의 공동 서비스 약속을 제공합니다.
선적 전 공장 테스트. 각 기계는 가능한 경우 고객의 금형을 사용하여 공장 현장에서 연속성 및 성능 테스트를 실행하므로, 라인은 장자강(Zhangjiagang)을 떠나기 전에 검증됩니다. 테스트는 사이클 타임, 캐비티 밸런스 및 첫 번째 부품 치수를 기록합니다.
금형 시험 및 초도품 검사. 금형은 실제 기계에서 시험되며 도면에 대해 넥 직경, 타원도, 실링 면 평탄도, 벽 분포 및 낙하 성능을 포괄하는 초도품 검사 보고서가 발행됩니다. 보고서에 서명되기 전까지 부품은 출하되지 않습니다.
설치 및 시운전. 엔지니어가 현장 설치와 시운전을 지원하고, 검증된 레시피를 공장 SD 카드로 전송하며, 현지 팀이 라인을 운영, 청소 및 유지보수하도록 교육합니다.
예비 부품 정책. Wanplas 그룹은 대상 기계에 대해 매년 USD 500 상당의 무료 부품을 제공하며, 보증 기간 내 손상된 부품은 무료로 교체됩니다. 이는 대규모 재고를 묶지 않고도 넓은 입구 용기 라인을 계속 가동할 수 있게 합니다.
교육 및 원격 운영. 운영자와 유지보수 직원은 현장에서 교육을 받으며, 기계는 원격 모니터링을 지원하여 Aibim 엔지니어가 현장 방문을 기다리지 않고 PLC 데이터를 읽고 비정상 상태에 대응할 수 있습니다.
오픈 팩토리. 고객은 Aibim 공장을 방문하여 제조 과정을 감사하고, 시험 가동을 지켜보고, 기계 부품을 생산하는 CNC 센터를 둘러볼 수 있습니다.
If you are planning a wide mouth jar program, send your part drawing, target volume, material and annual output to Aibim. The engineering team will propose a machine model, a cavity layout and a process window, and invite you to the factory for a mold trial and a line audit before you commit. There is no substitute for seeing your jar come off the machine with the neck in tolerance and the seal flat.
자주 묻는 질문(FAQ)
목 대 몸체 직경 비율이 얼마이면 광구(와이드 마우스) 병으로 정의되나요?
광구 병은 목-몸체 직경 비율이 0.5 이상, 일반적으로 0.55~0.85입니다. 좁은 목 병은 0.35 미만입니다. 비율이 클수록 개구부가 전체 몸체 직경에 가까워지며, 이는 블로우 역학을 바꾸고 벽 분포를 제어하기 어렵게 만듭니다.
광구 병에 압출 블로우 성형보다 사출 블로우 성형이 선호되는 이유는 무엇인가요?
IBM produces the neck finish by injection in a precision neck ring, so the opening is held to roughly plus or minus 0.05 mm with no flash and no post trim. For a wide mouth jar the opening is the critical sealing and filling surface, and IBM holds that surface to the tightest tolerance of the three processes.
식품 접촉용 광구(와이드 마우스) 병에는 어떤 재료가 가장 좋은가요?
For most food jars such as jam, honey, nuts and confectionery, polypropylene in homo-polymer or random co-polymer grade is the first choice because of its heat resistance, chemical inertness and food contact compliance. Transparent display jars use PS, SAN or PETG, while HDPE serves pharmaceutical powder and tablet jars.
넓은 입구 병 금형은 하나의 IBM 기계에서 몇 개의 캐비티로 작동할 수 있습니까?
Cavity count is limited by platen area because a wide mouth jar occupies far more mold space than a narrow neck bottle of equal volume. On an Aibim IBM75 a 1000 mL jar up to 120 mm mouth may run two cavities, while a 250 mL jar at 70 mm mouth can run four to six cavities. Larger cavitation is possible only on smaller diameter parts.
광구(와이드 마우스) 병 목의 타원형 또는 변형 원인은 무엇인가요?
타원도는 얇은 넥 벽, 넥 링의 불충분한 냉각 및 폴리머가 여전히 부드러운 상태에서의 탈형으로 인해 발생합니다. 대책은 넥 링의 독립 냉각 회로, PP의 경우 탈형 온도를 70도 C 미만으로 유지하고 넥 벽 두께에 0.2~0.5mm를 추가하는 것입니다.
광구 병의 최적 블로우 업 비율은 무엇인가요?
블로우업 비율을 2.0~3.5 범위로 유지하십시오. 그 이상이면 파리슨이 고르게 늘어날 수 없어 몸체는 두꺼운 채로 어깨와 바닥이 얇아집니다. 단차형 코어 로드 프로파일과 1.5~4.5mm 사출 벽 두께 구배를 통해 비율을 안전 범위 내에 유지할 수 있습니다.
광구(와이드 마우스) 병이 품질 사양을 충족하는지 어떻게 검증하나요?
Measure capacity at plus or minus 2 percent, neck inside diameter and ovality, seal face flatness at or below 0.15 mm, wall thickness at no fewer than eight points, top load in newtons, a 1.2 m full drop test, and seal retention under vacuum or pressure. Transparent jars also need light transmittance and haze checks.
