서론: 생산 능력 계산이 구매 결정을 좌우하는 이유
Accurate injection blow molding machine capacity calculation is the single most important step before you invest in a production line for pharmaceutical, cosmetic, or food small bottles. The headline number a supplier quotes is meaningless until you understand the formula behind it: how the cycle time, the number of mold cavities, the hours you actually run each day, and your real equipment effectiveness combine into a daily and yearly bottle count. This article gives you the exact equations, walks through two fully worked examples on real Aibim machines, and shows you how to translate a target output into a concrete machine and mold specification.
Aibim, a Wanplas factory with more than 12 years of experience in injection blow molding and machines running in over 40 countries, builds the IBM55 Hybrid Electric, IBM65, and IBM75 series for containers from 3 ml to 1000 ml. Those three models cover the full range of small-bottle production, and every capacity figure in this guide is built around their real operating envelope. Whether you make 5 ml oral-dose vials, 30 ml cosmetic jars, or 500 ml pharmaceutical shampoo bottles, the same formulas apply, only the input values change.
By the end of this guide you will be able to calculate theoretical hourly output, adjust it with an OEE factor, project daily and yearly volume, size the right cavity count, and estimate energy use in kilowatt-hours per 1,000 bottles. You will also see where most capacity estimates go wrong, and how to avoid quoting a number your line can never reach. No currency figures are used; all cost framing is shown as relative tiers and all output is expressed in physical units such as bottles per hour or kilowatt-hours per 1,000 bottles.
사출 블로우 몰딩 기계가 병을 생산하는 방법
사출 blow molding is a one-step, three-station hollow molding process. Plastic raw material is first plasticized in the barrel by a reciprocating screw, then injected into a cavitated preform or parison mold at the injection station. The parison is a precisely shaped tube with the finished bottle neck already molded in. A rotating transfer system carries the hot parison to the blow station, where compressed air expands it against the cooled blow cavity to form the bottle. A final transfer moves the finished bottle to the ejection station, where it is stripped and the neck is held by a long-distance digital laser sensor for safe, flash-free removal.
Because the three stations operate in parallel rather than in sequence, one cycle of the machine completes one bottle per cavity, but the wall-clock time of a cycle is set by the slowest station. In practice the blow-and-cool station almost always governs the cycle, because the molten parison must cool enough to hold its shape before ejection. This parallel architecture is why an injection blow molding machine can deliver a finished, flash-free bottle with no post-molding trim operation, and why cycle time is so sensitive to bottle wall thickness and cooling efficiency.
The materials processed on Aibim machines include polyethylene (HDPE, LDPE, LLDPE), polypropylene, polystyrene, ABS, SAN, TPU, PC, and PCTG. Each has a different melt viscosity and cooling rate, which shifts the cycle time. 폴리프로필렌 and HDPE cool relatively quickly; polycarbonate and PCTG need longer cooling, so for the same bottle size the cycle will be longer and the achievable hourly output lower. When you calculate capacity, always anchor the cycle time to the actual material, not a generic average.
The three-station design also explains why injection blow molding is favored for pharmaceutical, cosmetic, and food small bottles: the bottle neck and thread are molded to tight tolerance at the injection stage, so there is no flash to trim and no contamination route from a secondary operation. That cleanliness is part of the value, but it does not change the math. Output still equals cycles per hour times cavities, adjusted for how well the line actually runs.
마스터 생산 능력 공식: 사이클 타임과 캐비티의 결합
모든 사출 블로우 성형 생산량 수치는 하나의 핵심 관계로 귀결됩니다. 이론적 시간당 생산량은 기계가 1시간 동안 완료할 수 있는 사이클 수에 사이클당 생산되는 양품 병 수를 곱한 값입니다.
이 공식은 "기계가 결코 멈추지 않고 모든 캐비티가 항상 성공한다면 한 시간에 이론적으로 몇 개의 병을 만들 수 있는가"라는 질문에 답합니다. 이는 현실이 아닌 상한선입니다. 상한선에서 생산을 계획할 수 있는 숫자로 이동하려면 효율성 계수를 곱합니다.
유효 시간당 생산량에서 일일 및 연간 생산량은 가동 시간과 일수에 따라 직접 결정됩니다.
종합하면 전체 체인은 다음과 같습니다:
이 단일 체인은 기사 나머지 부분의 모든 추정의 핵심입니다. 생산 능력 계획의 기술은 단순한 산술이 아니라 t_c, N, OEE, H 및 D에 대한 현실적인 값을 선택하는 것입니다. 다음 섹션은 실제 Aibim 기계에서 계산된 숫자로 각 값을 설정하는 방법을 보여줍니다.
IBM 사이클 타임 분석
The cycle time t_c is the wall-clock seconds for one full rotation of the three-station machine. Because stations run in parallel, t_c equals the longest single-station time, not the sum of all three. Understanding the breakdown lets you see where a cycle can be shortened and where it is physically fixed by cooling.
| Station or phase | What happens | Typical time (seconds) | Usually gating? |
|---|---|---|---|
| 사출 station | Plasticize and inject parison, then screw recovery | 2.0 to 3.5 | No (overlaps next) |
| Blow and cool station | Air blow, wall cooling, shape set | 4.5 to 11.0 | Yes (slowest) |
| Ejection and transfer | Stripping, laser safety check, index | 1.2 to 2.0 | No |
| Resulting machine cycle | Set by the longest station | 8 to 16 | Reference |
In this breakdown the blow-and-cool station dominates. For a 100 ml HDPE bottle the cooling might be 6 seconds; for a 500 ml PCTG bottle it can stretch past 10 seconds because more mass must solidify. Screw recovery at the injection station often overlaps the cooling at the blow station, which is exactly why the parallel layout keeps the cycle near the blow time instead of adding all phases together.
Two practical levers shorten t_c. First, optimize cooling with chilled mold temperature control and, where the material allows, a thinner controlled wall, because cooling time scales with wall thickness squared in simplified heat-transfer terms. Second, use a machine with strong, stable clamping and fast indexing so the transfer and ejection phases stay short. Aibim’s single-crossbeam double-pole clamping framework and enlarged mold space are built to keep those non-cooling phases minimal.
계산 예 1: Aibim IBM75의 일일 생산량
6개 캐비티 금형에서 100ml HDPE 의약품 병을 생산하는 Aibim IBM75의 일일 출력을 계산해 보겠습니다. 하루 총 22시간 가동으로 2교대에 부분 3교대를 더해 운영합니다. 나중에 자신의 값을 대입할 수 있도록 단계별로 숫자를 계산하겠습니다.
1단계, 사이클 시간을 설정합니다. 100 ml HDPE 병의 경우 블로우-앤-쿨 스테이션이 약 12초로 지배하며, 사출과 이젝션이 그 창 안에서 겹칩니다. 따라서 t_c = 12초입니다.
2단계, 이론상 시간당 생산량에 대한 기본 공식을 적용합니다.
3단계, OEE 적용. 라인이 가동률 0.92, 성능 0.95, 품질 0.99로 운영된다고 가정하십시오. OEE = 0.92 x 0.95 x 0.99 = 0.865. 이는 잘 운영되는 제약 라인의 건강하고 현실적인 수치입니다.
4단계, 운전 시간을 곱합니다.
So this configuration delivers about 34,250 finished 100 ml bottles every day. If you ran only a single 8-hour shift, the same machine would produce roughly 12,456 bottles per day, which shows how strongly the operating-hours input drives the result. The table below summarizes the sensitivity of daily output to the shift pattern, holding cycle, cavities, and OEE constant.
| Operating hours per day (H) | Shift pattern | Daily output (bottles) | Relative to 24 h |
|---|---|---|---|
| 8 | Single shift | 12,456 | 0.33 |
| 16 | Double shift | 24,912 | 0.66 |
| 20 | Double shift plus buffer | 31,140 | 0.83 |
| 22 | Near-continuous | 34,254 | 0.91 |
| 24 | Continuous | 37,368 | 1.00 |
Notice that moving from 22 to 24 hours adds only about 9 percent output but removes the planned downtime window used for mold changes and preventive maintenance. Most producers choose 20 to 22 hours to keep that buffer, which is why the 22-hour figure is a sensible planning baseline rather than the maximum.
계산 예 2: 연간 생산량 및 생산 능력 계획
이제 IBM75 예시를 1년 전체로 확장하고 IBM55 Hybrid Electric의 더 높은 캐비티 소형 병 시나리오와 비교하십시오. 연간 생산량은 공장 관리자가 실제로 관심을 갖는 질문, 즉 이 라인이 연간 수요를 충족할 수 있는지에 답합니다.
하루 34,254병을 생산하는 IBM75를 기준으로 연간 300일 가동한다고 가정합니다(공휴일, 계획된 유지보수, 수요가 적은 기간을 고려).
이는 6-캐비티 금형을 갖춘 IBM75 한 대에서 연간 약 1,030만 개의 100ml 병입니다. 이제 빠른 8초 사이클의 12-캐비티 금형에서 15ml PP 의약품 바이알을 생산하고 OEE 0.85로 24시간 가동하는 IBM55 Hybrid Electric을 고려하십시오.
The hybrid electric small-vial line therefore delivers roughly 36.4 million bottles per year, more than three times the IBM75 figure, driven by the higher cavity count and shorter cycle rather than by a bigger machine. This contrast is the central lesson of capacity planning: for small bottles, cavities and cycle time dominate, while for large bottles, cooling time and lower cavity counts cap the rate no matter how many machines you buy.
| Scenario | Model | Cavities | Cycle (s) | OEE | Yearly output |
|---|---|---|---|---|---|
| 100 ml HDPE, 300 d, 22 h | IBM75 | 6 | 12 | 0.865 | 10.28 million |
| 15 ml PP, 330 d, 24 h | IBM55 Hybrid | 12 | 8 | 0.85 | 36.35 million |
| 250 ml PP, 300 d, 20 h | IBM65 | 8 | 11 | 0.82 | 19.07 million |
When you plan capacity, build the yearly figure first from demand, then work backward to the model and cavity count. If annual demand is 20 million 250 ml bottles, the IBM65 row above already meets it; if demand is 40 million 15 ml vials, you would need roughly two IBM55 Hybrid lines or one line run at higher OEE and longer hours. Capacity planning is always a backward calculation from the demand target.
OEE: 가용성, 성능 및 품질
종합 설비 효율(OEE)은 이론상 최대치를 재무 및 생산 팀이 신뢰할 수 있는 수치로 바꾸는 방법론입니다. OEE는 각각 0에서 1 사이의 세 가지 독립적인 비율의 곱입니다.
Availability captures unplanned stops and planned downtime such as mold changes. A line planned for 22 hours but actually running 20.2 hours due to a 1.8-hour mold change has availability of 20.2 / 22 = 0.918. Performance captures speed loss: if the machine should run at a 12-second cycle but averages 12.6 seconds because of minor slowdowns, performance is 12 / 12.6 = 0.952. 품질 captures scrap: if 1 percent of bottles are rejected for short shots or visual defects, quality is 0.99.
이들을 곱하면 OEE = 0.918 x 0.952 x 0.99 = 0.865로, IBM75 예에서 사용된 수치와 정확히 일치합니다. 아래 표는 고정된 이론적 시간당 1,800병에 대해 OEE 등급이 유효 생산량을 어떻게 바꾸는지 보여줍니다.
| OEE tier | Typical meaning | Effective bottles per hour | Loss vs theoretical |
|---|---|---|---|
| 0.60 | Poor, frequent stops | 1,080 | 40% |
| 0.75 | Average, typical SME | 1,350 | 25% |
| 0.85 | Good, well-run line | 1,530 | 15% |
| 0.90 | Excellent, world class | 1,620 | 10% |
The gap between a 0.60 line and a 0.90 line is 50 percent more output from the identical machine. That is why Aibim emphasizes pre-shipment testing, remote monitoring of PLC data, and rapid spare-parts support: those services attack the availability and performance losses that quietly destroy quoted capacity. When a supplier quotes output, always ask which OEE assumption sits behind it.
Aibim IBM 기계 시리즈 및 실제 사양
Aibim’s three production models share the same three-station one-step architecture, PREFILL hydraulic technology, and CE-certified safety system, but they are sized for different bottle volumes and cavity counts. The specification tables below use the standard technical envelope of each series; exact values should be confirmed against the factory quotation for your specific mold and material. All three are built in Aibim’s own CNC center, which supports tight tolerances on clamping and transfer that protect cycle-time stability.
IBM55 하이브리드 전동 사출 블로우 성형기
IBM55 Hybrid Electric은 서보-유압 클램프와 전기 보조 드라이브를 결합하여 에너지 소비를 줄이면서 소형 병에서 빠른 사이클을 달성합니다. 고캐비티 바이알 및 샘플 생산에 적합한 기반입니다.
| Parameter | IBM55 Hybrid Electric |
|---|---|
| Clamping force | 55 tons (540 kN) |
| Screw diameter | 35 mm |
| L/D ratio | 20:1 |
| Container volume range | 3 ml to 100 ml |
| Max neck diameter | 38 mm |
| Max cavities | 14 |
| Typical cycle time | 6 to 9 seconds |
| Installed power | 14.5 kW |
| 기계 무게 | about 4.8 t |
IBM65 사출 블로우 성형기
IBM65는 50~350 ml 화장품 및 의약품 병을 위한 중급 작업용 기계로, 가장 일반적인 소형 병 포맷에 맞춰 캐비티 수와 클램핑 공간의 균형을 맞춥니다.
| Parameter | IBM65 |
|---|---|
| Clamping force | 65 tons (640 kN) |
| Screw diameter | 40 mm |
| L/D ratio | 20:1 |
| Container volume range | 3 ml to 350 ml |
| Max neck diameter | 45 mm |
| Max cavities | 10 |
| Typical cycle time | 8 to 13 seconds |
| Installed power | 21 kW |
| 기계 무게 | about 6.5 t |
IBM75 사출 블로우 성형기
IBM75는 시리즈 중 가장 큰 모델로, 캐비티 수가 적고 냉각 시간이 길어질 수밖에 없지만 사출 블로우 성형의 넥 정밀도가 여전히 요구되는 350~1000ml 병을 위해 제작되었습니다.
| Parameter | IBM75 |
|---|---|
| Clamping force | 75 tons (735 kN) |
| Screw diameter | 45 mm |
| L/D ratio | 20:1 |
| Container volume range | 3 ml to 1000 ml |
| Max neck diameter | 55 mm |
| Max cavities | 8 |
| Typical cycle time | 10 to 18 seconds |
| Installed power | 28 kW |
| 기계 무게 | about 8.5 t |
The screw diameter and L/D ratio determine plasticizing capacity; for these small-bottle machines a 20:1 L/D with a 35 to 45 mm screw supplies more than enough melt for the parison without over-residence time that could degrade heat-sensitive resins. The clamping force scales with bottle area and blow pressure, and the figures above leave comfortable margin for stable molding at the stated cavity counts.
캐비티 수 및 병 용량 선택
Cavity count is the strongest lever you control after choosing the model. More cavities multiply output directly, but each cavity adds cooling load and mold cost, and very large bottles physically cannot fit many cavities in the platen. The table below maps typical bottle volumes to a sensible cavity count and the resulting cycle on Aibim machines.
| Bottle volume | Recommended model | Typical cavities | Typical cycle (s) | Theoretical per hour |
|---|---|---|---|---|
| 3 to 15 ml | IBM55 Hybrid | 12 to 14 | 6 to 8 | 5,400 to 6,300 |
| 15 to 50 ml | IBM55 Hybrid / IBM65 | 10 to 12 | 7 to 10 | 3,600 to 5,100 |
| 50 to 150 ml | IBM65 | 8 to 10 | 9 to 12 | 2,400 to 3,000 |
| 150 to 350 ml | IBM65 / IBM75 | 6 to 8 | 11 to 14 | 1,540 to 2,180 |
| 350 to 1000 ml | IBM75 | 4 to 6 | 14 to 18 | 800 to 1,540 |
To pick cavities, start from your required effective hourly output, divide by your expected OEE and by 3,600 divided by the cycle, then round to the nearest practical cavity count the model supports. For example, if you need 3,000 good 80 ml bottles per hour at OEE 0.85, you need theoretical 3,529 per hour; at a 10-second cycle that is 9.8 cavities, so choose a 10-cavity mold on the IBM65. The calculation is reversible, which is exactly why it is so useful during quotation.
에너지 소비: 병 1,000개당 킬로와트시
에너지는 용량과 연계된 비용으로, 구매자들이 처리량과 함께 점점 더 중요하게 고려합니다. 이를 병 1,000개당 킬로와트시로 표시하면 생산량에 따라 깔끔하게 확장되고 통화와 무관합니다.
IBM75의 경우 시간당 1,557개의 유효 병과 약 17 kW의 실제 소비 전력(PREFILL 기술을 사용한 정상 부하에서 28 kW 설치 정격의 약 60%)일 때 수치는 다음과 같습니다:
시간당 4,590병의 유효 생산량과 약 9 kW의 소비 전력을 가진 IBM55 하이브리드의 경우(하이브리드 전기 설계 덕분에 14.5 kW 설치 정격보다 훨씬 낮음):
하이브리드 전기 소형 병 라인은 킬로와트시당 훨씬 더 많은 병을 생산하므로 병당 에너지 효율이 극적으로 높습니다. 아래 표는 대표 부하에서 병 1,000개당 기준으로 세 가지 모델을 비교합니다.
| Model | Effective bottles per hour | Approx. running power (kW) | kWh per 1,000 bottles | 에너지 tier |
|---|---|---|---|---|
| IBM55 Hybrid | 4,590 | 9 | 1.96 | Low |
| IBM65 | 2,600 | 13 | 5.00 | Medium |
| IBM75 | 1,557 | 17 | 10.9 | Medium |
Aibim’s PREFILL technology and variable displacement pump pressurizing in the hydraulic system are the reason these running powers sit well below the installed ratings, targeting at least 35 percent energy saving against conventional hydraulic units. When you compare machines, always ask for the running power at your cycle and cavity count, not the nameplate installed power, because the gap between the two is where the real saving lives.

아래 표는 일반적인 생산 요구 사항을 권장 Aibim 모델 및 캐비티 시작점으로 직접 변환합니다. 이를 첫 번째 필터로 사용한 다음 자체 사이클과 OEE로 전체 공식을 실행하여 일일 및 연간 수치를 확인하십시오.
| Requirement | Recommended model | Cavities | Target daily output |
|---|---|---|---|
| 5 to 15 ml pharma vials, high volume | IBM55 Hybrid Electric | 12 to 14 | 90,000 to 110,000 |
| 20 to 50 ml cosmetic jars | IBM55 Hybrid / IBM65 | 10 to 12 | 55,000 to 85,000 |
| 50 to 150 ml food and pharma | IBM65 | 8 to 10 | 40,000 to 55,000 |
| 150 to 350 ml shampoo or lotion | IBM65 / IBM75 | 6 to 8 | 28,000 to 40,000 |
| 350 to 1000 ml wide-mouth bottles | IBM75 | 4 to 6 | 14,000 to 30,000 |
If your target daily output sits between two rows, choose the larger model for headroom, because running a smaller machine at its absolute maximum cycle leaves no buffer for OEE losses. Aibim engineers can confirm the exact mold cavity layout and verify the cycle on your material during pre-shipment testing.

Aibim IBM 기기의 응용 산업
Aibim 기계는 최대 용량보다 넥 정확도와 청결이 더 중요한 소형, 고정밀, 무플래시 병을 위해 제작되었습니다. 공장 프로필의 실제 응용 분야는 의약품, 식품, 음료 및 화장품이며 각각 특정 최종 제품에 매핑됩니다.
In pharmaceuticals, the bottles are oral-dose vials, eye-drop bottles, nasal spray actuators, and small dropper containers, typically 3 to 100 ml in HDPE, PP, or cyclic olefin and COP-like materials where the molded neck guarantees a leak-tight closure. In food and drink, the products are single-serve sauce cups, honey and syrup bottles, flavored-milk shot bottles, and condiment containers where the one-step process avoids post-mold trimming that could introduce foreign particles. In cosmetics, the dominant formats are 15 to 100 ml cream jars, serum bottles, and sample vials in PP, PS, SAN, and PCTG where surface finish and thread quality drive shelf appeal.
Because the three-station process holds the neck to injection-molded tolerance, these bottles meet the hygiene expectations of pharmaceutical and food lines without secondary operations. For regulated markets, the materials and machine surfaces should be specified to relevant standards such as FDA food-contact and ISO 10993 biocompatibility where applicable, and the machine carries CE certification with a light curtain and laser safety sensor at the stripper station.
설치, 시운전 및 유지보수
Capacity is only realized if the machine is installed and maintained so it actually runs at the assumed OEE. Aibim supports installation and commissioning by engineers who set the machine on the prepared foundation, connect utilities, level the frame, and run the first production cells on the customer mold and material. Commissioning includes verifying the actual cycle time, recording the first stable hourly output, and documenting the baseline OEE so later losses are visible.
Routine maintenance that protects capacity includes screw and barrel wear inspection on the plasticizing unit, hydraulic oil analysis on the clamping system, mold cooling-channel descaling to keep cycle time short, and calibration of the blow air and stripper laser sensor. Because Aibim runs its own CNC center for machine parts, wear items and spare molds can be reproduced to original tolerance, which shortens any downtime. The SD card parameter storage lets a proven recipe be copied across machines, reducing changeover time that would otherwise erode availability.
서비스 및 지원
Aibim, as a Wanplas factory, extends the group’s shared service promises to every IBM line. The Wanplas brand commits to USD 500 free parts every year for the covered line, free replacement of damaged parts within the warranty, and an open-factory policy that welcomes customer visits for inspection and audit before and after purchase. Wanplas, with its network of specialized factories, backs these promises with a track record of 100+ lines per year from Aibim alone and machines running in 40+ countries.
Support also covers pre-shipment testing on the customer’s mold and material so the quoted daily and yearly output reflects measured performance, on-site installation and commissioning, operator training on setup and maintenance, and remote operation and maintenance through PLC data monitoring that lets engineers check running status and respond to abnormal feedback. These services directly defend the availability and performance components of OEE, which as shown earlier can mean the difference between 1,080 and 1,620 effective bottles per hour on the same machine.
자주 묻는 질문(FAQ)
사출 블로우 성형기 생산량의 기본 공식은 무엇입니까?
The theoretical hourly output equals 3,600 divided by the cycle time in seconds, multiplied by the number of cavities. In symbols: Q_theoretical = 3,600 / t_c x N. Multiply by an overall effectiveness factor (OEE) and the operating hours per day to get the daily figure, then by operating days per year for the yearly figure.
3스테이션 IBM 기계의 사이클 타임을 어떻게 추정합니까?
A three-station one-step IBM machine runs injection, blow, and ejection in parallel, so the cycle is gated by the longest station, almost always the blow-and-cool station. Add the parison injection time, the blow-and-cool time, and the transfer or ejection time; the station that takes the longest sets the machine cycle. Larger bottles need longer cooling and therefore a longer cycle.
이론상 최대 생산량보다 OEE가 더 중요한 이유는 무엇입니까?
Theoretical output assumes the machine never stops and every cavity always produces a good bottle. Real lines lose time to mold changes, material changeovers, minor faults, speed loss, and scrap. OEE multiplies availability, performance, and quality, and a realistic OEE of 0.75 to 0.85 typically cuts the theoretical number by 15 to 25 percent. Capacity planning should always use the OEE-adjusted figure.
주어진 병 용량에 대해 몇 개의 캐비티를 선택해야 하나요?
Cavity count trades against bottle size and cooling demand. Small volumes such as 3 to 30 ml pharmaceutical vials support 10 to 14 cavities, mid volumes such as 50 to 250 ml support 6 to 10 cavities, and large volumes up to 1000 ml support 4 to 8 cavities. The right number keeps the cycle short while staying within the clamping force and mold space of the chosen model.
IBM 라인의 에너지 소비량은 어떻게 계산되나요?
Measure the actual running power in kilowatts during stable production, then divide by the effective hourly output and multiply by 1,000 to get kilowatt-hours per 1,000 bottles. Aibim machines with PREFILL hydraulic technology and variable displacement pumps are engineered to save at least 35 percent energy against conventional hydraulic units, which directly lowers this figure.
중간 규모의 일일 생산 목표에는 어떤 Aibim 모델이 적합할까요?
For a target around 30,000 to 45,000 bottles per day of 50 to 250 ml containers, the IBM65 is a balanced choice with up to 10 cavities and an 8 to 13 second cycle. For smaller high-volume vials the IBM55 Hybrid Electric reaches higher cavity counts, while the IBM75 covers larger 350 to 1000 ml bottles at lower cavity counts.
생산 능력은 24시간 가동을 기준으로 계획해야 하나요, 아니면 더 적게 계획해야 하나요?
It depends on labor, utility cost, and demand stability. A single 8 hour shift gives roughly one third of a 24 hour plan, while a two-shift 22 hour plan captures most of the benefit with time reserved for mold changes and maintenance. Many pharmaceutical and cosmetic producers run 20 to 22 hours per day to balance output with planned downtime.
기계 구매 전에 이러한 계산의 정확도는 어느 정도인가요?
The formulas are exact; the uncertainty sits in the input values. Cycle time, cavity count, and OEE should be confirmed by a real trial run on the actual mold and material. Aibim offers pre-shipment testing on the customer mold and material so the quoted daily and yearly output reflects measured performance rather than a textbook estimate.
결론
사출 blow molding machine capacity calculation comes down to one dependable chain: yearly output equals 3,600 divided by cycle time, times cavities, times OEE, times operating hours per day, times operating days per year. The arithmetic is simple; the discipline is in the inputs. Anchor the cycle time to your real material and bottle, choose cavities the model can actually hold, apply a realistic OEE of 0.75 to 0.85, and plan 20 to 22 operating hours per day rather than a perfect 24. Do that and your quoted output will match what the line delivers.
Aibim’s IBM55 Hybrid Electric, IBM65, and IBM75 cover the full 3 ml to 1000 ml small-bottle range with the three-station one-step process, PREFILL hydraulic technology, and CE-certified safety that keep cycle times short and energy per 1,000 bottles low. If you are scoping a new line, send your bottle drawing, target daily or yearly volume, and material to the Aibim team for a tailored capacity calculation and a verified quotation, and schedule a factory audit or a trial run on your mold to confirm the numbers before you commit. The Wanplas group’s shared promises, including USD 500 free parts every year and an open-factory policy, support the line long after startup.
