Aibim, a Wanplas factory with more than twelve years dedicated to hollow molding and two decades of accumulated know-how in injection blow molding, builds the three-station, one-step machines that personal care brands rely on for precise small-format containers. The 150ml class sits at the commercial heart of the body and facial care segment, where a body lotion bottle and a facial cleanser tube must combine an attractive shelf profile with airtight necks, uniform wall thickness, and zero flash that would otherwise require trimming and secondary handling. Producing these parts on an injection blow molding machine means the parison is injected first and then blown in a single index motion, so the container leaves the mold finished, decorated-ready, and dimensionally repeatable at high cavitation.
What Injection Blow Molding Delivers for the 150ml Format
Injection blow molding is the process of choice when a container needs a fully formed, thread-true neck and a consistent sidewall without a parting line around the body. In this one-step, three-station cycle the injection station forms a precisely weighted parison around a core rod, the transfer station rotates that rod into the blow station, and the blow station expands the parison against a cooled cavity to set the bottle or tube shape. Because the neck is molded by injection rather than pinched from a parison, the finish, thread, and sealing land are produced to tight tolerances that survive automated capping and pumping. For a 150ml body lotion bottle or a facial cleanser tube, that neck integrity is what protects the formula from oxygen ingress and prevents leaks during shipping and daily use.
The three-station architecture also removes the trimming step that defines extrusion blow molding. There is no flash ring at the base and no weld line across the sidewall, so the part is cosmetically clean straight from the machine and needs no deflashing, no post-mold cutting, and no regrind handling for that scrap. The finished container is therefore lighter and cleaner, and the line runs with fewer operators and less downstream equipment. For contract manufacturers serving multiple personal care clients, this clean-part discipline translates directly into lower labor cost per thousand pieces and a more predictable quality record.
Another advantage specific to the 150ml size is cavitation efficiency. The parison core rods are compact, so a single IBM platen can carry multiple cavities tuned to the same or different heights within the same shot envelope, lifting hourly output without enlarging the machine footprint. Aibim machines are engineered around this principle, pairing a robust single-crossbeam, double-pole clamping framework with an enlarged mold-setting space that accommodates multi-cavity tools for the small cosmetic format. The result is a production cell that fits a modest floor area yet sustains the throughput that private label and branded personal care lines demand.
Why the 150ml Size Class Dominates Body and Facial Care
The 150ml volume has become a default for premium body lotion and facial cleanser packaging because it signals a full-size yet travel-friendly product that sits comfortably in the hand and on the retail shelf. Lotion bottles in this range are typically used at the bathroom sink or in the shower, where a stable base, a controlled dispensing neck, and a wall thick enough to survive drops matter more than maximum light weight. Facial cleanser tubes and tube-style bottles in the same volume are carried in gym bags and wash kits, so they must resist denting and must not weep from the cap. The 150ml class therefore rewards the very qualities that injection blow molding controls best: neck accuracy, wall uniformity, and material efficiency.
From a branding perspective, the 150ml container is a canvas. The injection-molded body accepts high-gloss or matte cavity finishes, in-mold color through masterbatch dosing, and a clean shoulder that supports screen printing, hot stamping, or label-free decoration. Because IBM parts carry no flash and no pinch weld, the entire external surface is available for graphics, and the sidewall thickness can be tuned so the bottle feels substantial without wasting resin. Aibim supports this by running its own CNC center for machine and tooling components, which shortens the loop between a customer’s container drawing and a proven production mold.
Market behavior reinforces the trend. Personal care buyers increasingly favor mid-volume formats that reduce single-use waste while remaining cost-competitive, and the 150ml bottle answers that with a refill-friendly shape and a durable wall. Brands that launch a 150ml lotion and a matching 150ml cleanser under one visual system create a coherent range, and a single IBM machine platform can serve both shapes by swapping cavity tooling rather than re-qualifying a completely different process. Wanplas, as the parent brand aggregating the Aibim factory’s hollow molding program, positions this flexibility as a shared advantage for customers building a coordinated personal care line.
Material Selection for Lotion Bottles and Cleanser Tubes
Material choice decides how the 150ml container performs in the bathroom, on the shelf, and through the filling line. High-density polyethylene remains the workhorse for body lotion bottles because it offers a soft natural feel, good chemical resistance to surfactants and emollients, and easy processing on IBM with a stable parison. Polypropylene brings a higher heat deflection temperature and a crisper, more rigid hand-feel that suits facial cleanser tubes that may see warm water exposure, and it accepts living-hinge and snap-fit features well. For premium clarity or a glass-like cosmetic look, PCTG and PETG process cleanly on Aibim machines, though they demand tighter drying and temperature control than polyolefins.
Specialty resins broaden the design space. SAN and ABS deliver gloss and rigidity for decorative caps-in-body concepts, while TPU and certain elastomeric grades can be molded for soft-touch grips on the shoulder or base. PC is available for demanding clarity and impact needs but requires strict drying and a controlled melt temperature to avoid hydrolytic degradation. The selection must also respect the formula: a lotion with a high essential-oil or solvent content may need a barrier-minded resin or a fluorination-free additive system, and the molder should validate compatibility with the actual filled product rather than assuming generic resistance.
The table below maps common 150ml personal care container requirements to candidate materials processed on Aibim injection blow molding machines, with the trade-offs a packaging engineer should weigh before locking a resin.
| Material | Best For | Key Property | Note |
|---|---|---|---|
| HDPE | Lotion bottle | Soft touch, chemical resistance | Easy IBM processing |
| PP | Cleanser tube | Heat resistance, rigidity | Slightly higher set temp |
| PCTG/PETG | Premium clear bottle | Glass-like clarity | Requires drying |
| SAN/ABS | Rigid decorative part | Gloss, dimensional stability | Limit essential-oil contact |
| TPU | Soft-touch grip | Elasticity | Narrow window |
Drying discipline protects quality for hygroscopic grades. PETG, PCTG, PC, and ABS must be dried to a low moisture content before plasticizing, because residual water drives hydrolytic chain scission that shows up as brittle necks, silvery splay, and poor weld at the base. Aibim’s process guidance pairs these resins with dehumidifying drying and a stabilized barrel temperature profile so the parison arrives at the blow station with consistent viscosity. For polyolefins the priority shifts to uniform melt temperature and screw recovery consistency, which the machine’s plasticizing unit controls through closed-loop back pressure and screw rotation speed.
Aibim Injection Blow Molding Machine Portfolio for the 150ml Class
Aibim offers a focused three-model line that covers the 3ml to 1000ml hollow container range, with the 150ml personal care format sitting comfortably inside the sweet spot of each machine. The IBM75 is the volume workhorse, the IBM65 a compact cell for mid output, and the IBM55 a hybrid electric variant that cuts energy draw while keeping the same tooling philosophy. All three share the three-station, one-step architecture, the single-crossbeam double-pole clamping frame, and the SD-card parameter storage that lets a validated recipe move from one machine to another without re-tuning.
The IBM75 carries the largest platen and clamping envelope in the Aibim range and is the natural choice when a 150ml lotion or cleanser program needs high cavitation and long unattended runs. Its hydraulic system uses Aibim’s PREFILL technology together with a variable displacement pump pressurizing design that reduces idle energy and smooths the clamp motion, contributing to the factory’s stated minimum thirty-five percent energy saving versus conventional hydraulic lines. For a personal care filler running several million bottles a year, that saving is a measurable line-cost reduction rather than a footnote.
| Spec | IBM75 | IBM65 | IBM55 |
|---|---|---|---|
| Container range | 3-1000 ml | 3-1000 ml | 3-1000 ml |
| Drive type | Hydraulic | Hydraulic | Hybrid electric |
| Stations | 3 | 3 | 3 |
| Energy saving | min 35% | min 35% | Higher |
| Clamp frame | Single crossbeam | Single crossbeam | Single crossbeam |
The IBM65 answers the same 150ml application in a smaller, often lower-investment cell that still benefits from Aibim’s reasonable structure and convenience features. It suits a brand bringing a second format to market, a regional filler with moderate annual volume, or a production floor where two smaller machines give more scheduling flexibility than one large unit. Because the IBM65 uses the same core-rod and cavity tooling logic as the IBM75, tooling developed for one can be evaluated and, where the clamp envelope allows, transferred with minimal rework, protecting the customer’s mold investment.
The IBM55 hybrid electric model targets operations where power cost, cooling load, and a quieter, cleaner machine room rank high on the buying checklist. By electrifying key motions while retaining the proven hydraulic clamp assist, the IBM55 keeps the robust clamping frame and the precise parison control that define Aibim quality, yet trims the energy and heat footprint that pure hydraulic lines impose. For a cosmetics manufacturer pursuing a lower-carbon production story, the IBM55 is the natural entry into the 150ml bottle and tube program without sacrificing the neck accuracy that automated filling demands.
All Aibim machines are CE certified, with a stripper station protected by a long-distance digital laser sensor for mold safety and a light curtain for personal safety, so the cell meets European machinery requirements out of the crate. The convenience system stores process recipes on an SD card, allowing a validated lotion-bottle setting to be copied onto a sister machine in minutes, which is especially valuable for contract manufacturers running dozens of SKUs across several lines. The reasonable structure, with enlarged mold-setting space, also makes multi-cavity tools for the 150ml class easier to build and service.
Process Window and Parameter Settings for Clean 150ml Parts
Dialing in a 150ml lotion bottle or cleanser tube means balancing injection, transfer, and blow phases so the parison is hot and homogeneous at the moment of inflation yet cool enough at the neck to hold thread form. The injection station sets parison weight and distribution through melt temperature, injection speed, and holding pressure; the transfer station carries the core rod without disturbing that distribution; and the blow station applies calibrated air pressure and a cavity cooling time that freezes the shape before ejection. Aibim’s closed-loop plasticizing keeps melt pressure and temperature steady across the run, which is what keeps wall thickness within tolerance shift after shift.
Typical levers a process engineer tunes are shown below as a starting reference rather than a fixed recipe, because the optimum depends on resin, cavitation, and bottle geometry. Polyolefins run at moderate melt temperatures with firm but not excessive holding pressure, while clear amorphous grades need tighter temperature control and longer, gentler cooling to avoid stress and haze. The blow air pressure and timing must inflate the parison fully into the corners of the shoulder and base without overstretching the sidewall, which would thin the wall and weaken drop performance.
| Phase | Control | Effect |
|---|---|---|
| Injection | Melt temp, speed | Parison weight, fill |
| Transfer | Rod temp, timing | Distribution hold |
| Blow | Air pressure, time | Wall, corner fill |
| Cooling | Mold temp, time | Dimensional stability |
| Eject | Stripper sensor | Safe part release |
Defect control follows the standard diagnostic path: short corners point to insufficient blow pressure or a cold parison, while a thin sidewall or weep at the base signals over-blow or poor parison distribution. Silver streak indicates moisture or trapped gas in the melt, addressed by drying and venting; sink at the shoulder comes from inadequate holding or hot material in a thick section. Aibim’s recipe management and remote monitoring let the line owner track these parameters over time, and the factory’s engineers can review PLC data to flag drift before it becomes scrap.
Neck Finish, Wall Thickness, and Dimensional Consistency
For a 150ml body lotion bottle or facial cleanser tube, the neck is the commercial and functional centerpiece. Injection blow molding produces a neck by injecting around the core rod, so the thread form, sealing land, and inner bore are molded to the cavity, not pinched or cut. That yields a finish compatible with standard cosmetic closures, pumps, and flip caps, and it holds torque and seal performance through automated capping at high line speed. Consistent neck dimensions also reduce capper jams and rejected fills, a quiet but real contribution to overall equipment effectiveness.
Wall thickness control is where IBM separates from processes that leave a heavy base or an uneven sidewall. Because the parison is a solid injected preform, its wall can be shaped to put material where it is needed — more at the shoulder for drop resistance, thinner across the body to save resin — and then blown to a repeatable profile. Aibim’s mold-setting space and stable clamp allow multi-cavity tools that hold this profile across every cavity, so a 150ml bottle from cavity one and cavity sixteen leave the cell within a tight weight band. That consistency protects both the brand’s feel in the hand and the filler’s target grams per bottle.
Dimensional stability also depends on cooling discipline. The blow cavity must extract heat evenly, or the bottle will warp as it relaxes after ejection, throwing off labeling and capping. Aibim designs the cooling circuit and cycle timing so the part sets uniformly, and the SD-card recipe system stores the proven cooling window so it is reproduced on every restart. For customers switching between a lotion bottle and a cleanser tube, locking the correct recipe per SKU removes operator guesswork and keeps first-pass yield high.
Applications Across Body Care and Facial Care
The 150ml injection blow molded container serves a wide slice of the personal care catalog. Body lotion bottles in HDPE or PP benefit from the soft hand-feel and chemical resistance needed for emollient formulas, while facial cleanser tubes and tube-style bottles gain a precise neck for flip caps and pumps that survive daily squeezing. Aibim’s stated application fields — pharmaceutics, food, drink, and cosmetic — map directly onto these needs, and the machines process the resin set that those segments require, from commodity polyolefins to clarity grades.
Beyond the two headline products, the same 150ml platform extends to hand creams, shampoo and conditioner concentrates, serum and essence bottles, and sample or travel formats that mirror a brand’s full-size line. Because the machine is a one-step cell, a private label filler can run a lotion in the morning and a cleanser in the afternoon by changing cavity tooling and loading the stored recipe, without re-validating a separate process train. Wanplas supports this breadth by presenting Aibim’s hollow molding program as part of one coordinated personal care equipment offering.
The table below maps Aibim’s stated application fields to the 150ml container types those segments typically request, showing how one machine platform serves a coordinated personal care range.
| Field | 150ml Container | Common Resin |
|---|---|---|
| Cosmetic | Lotion bottle, cleanser tube | HDPE, PP |
| Pharmaceutics | Cream jar bottle | PP, PETG |
| Food | Sauce, condiment bottle | PP, HDPE |
| Drink | Shot, sample bottle | PETG, PP |
Regulatory fit matters for these segments. Containers that contact skin or, in adjacent pharma and food use, ingestible or mucosal products must meet the right compliance framework, and the resin and additive system should be selected against the applicable standard rather than assumed. Aibim’s process control helps here by keeping contamination risk low: the clean one-step cycle avoids the open parison handling that extrusion blow molding exposes to the environment, an advantage for sensitive formulations and cleanroom-adjacent production.

Selecting the Right Aibim Model for Your 150ml Program
Choosing between the IBM75, IBM65, and IBM55 starts with annual volume, available floor space, and the energy profile the operation wants. High-volume branded or contract lines leaning on maximum cavitation and lowest cost per piece should look first at the IBM75; space- or budget-constrained lines with moderate volume will find the IBM65 a balanced choice; and operations prioritizing the lowest power and cooling load should evaluate the IBM55 hybrid electric. The table below translates common 150ml program needs into a recommended starting model.
| Need | Volume | Recommended |
|---|---|---|
| Max cavitation | Very High | IBM75 |
| Balanced cell | Medium | IBM65 |
| Low energy | Medium | IBM55 |
| Multi-SKU flexibility | Variable | IBM75 or IBM65 |
| Green profile | Variable | IBM55 |
The decision should also weigh tooling strategy. Aibim’s own CNC center produces machine parts and supports mold development, so a customer’s container drawing can move quickly from concept to a proven multi-cavity tool tuned for the 150ml class. For a brand launching both a lotion bottle and a cleanser tube, designing the two tools on the same machine platform preserves recipe discipline and spare-part commonality, and it lets the filler shift capacity between SKUs as demand moves through the season. Wanplas’s shared service promises then apply across the installed base, simplifying support for multi-line sites.
Energy, Automation, and Production Economics
Operating cost for a 150ml IBM cell is dominated by energy, cooling water, compressed air, and labor. Aibim’s PREFILL hydraulics with a variable displacement pump cut idle and clamp energy, and the factory quotes a minimum thirty-five percent energy saving against conventional hydraulic machines of the same class. The hybrid IBM55 extends that advantage by electrifying motion, trimming both the power bill and the chiller load that a hot hydraulic room would otherwise impose. Over the machine’s service life, those savings compound and often outweigh the purchase-price difference between models.
Automation reduces labor per thousand bottles. Because IBM produces a finished, flash-free part, there is no deflashing station and no regrind stream to manage for that scrap, and the parts can move directly to leak testing, vision inspection, and palletizing. Aibim’s remote monitoring and recipe management let a small team supervise several lines, and the SD-card system shortens changeovers so the cell spends more time making saleable containers. For a contract manufacturer quoting per-piece pricing, this combination of energy efficiency and labor leanness is what protects margin when resin and power costs move.
Cost positioning should be stated in relative terms rather than fixed numbers. The IBM75 represents a Medium to High capital level with the lowest operating cost per piece at scale; the IBM65 sits at a Medium level with balanced economics; and the IBM55 carries a Higher upfront level offset by lower lifetime energy and cooling expense. None of these should be quoted as a fixed amount in writing — the right figure depends on cavitation, options, and destination — but the ranking helps a buyer frame the trade-off before requesting a formal configuration.
Quality, Certification, and In-House Machining
Aibim builds its machines as a Wanplas factory with an own CNC center, which means critical machine and tooling components are produced and controlled in-house rather than sourced blindly from outside shops. That vertical capability shortens lead times for spare parts and tooling revisions, and it lets the factory hold tighter tolerances on the clamp frame, core rods, and cavity sets that decide container quality. For a personal care customer, in-house machining translates into faster tool corrections when a lotion bottle shoulder needs a small revision or a cleanser tube neck tolerates a tighter closure.
Certification readiness is built in. Every Aibim machine is CE certified, satisfying the European machinery safety framework, and the safety design pairs a long-distance digital laser sensor at the stripper station with a light curtain for personnel protection. These are not add-on options but standard features, so a buyer exporting to regulated markets does not need a separate safety retrofit. The factory’s quality system also backs the Wanplas group promises on production capacity, transportation, and quality standards, giving the customer a documented fallback if agreed criteria are not met.
Traceability supports long runs. With recipe storage on SD cards and remote monitoring of PLC data, the production record for a given 150ml bottle or tube is reproducible and auditable, which matters when a brand needs to demonstrate process control to a quality auditor or a retailer’s supplier program. Aibim’s engineers can review line data and advise on parameter drift, turning the machine from a standalone asset into a managed part of the customer’s quality system.
Service, Support, and Factory Access
Buying an Aibim 150ml injection blow molding machine includes the Wanplas group’s shared after-sales commitments, which cover USD 500 free parts every year, free replacement of damaged parts within the warranty, and an open-factory policy that welcomes customer visits for inspection and acceptance. Engineers support installation and commissioning, track machine usage, and can remotely check PLC data to catch anomalies early. For a personal care filler scaling from one line to several, this continuity of support across the Aibim range simplifies training and spare-part planning.
The open-factory approach lets a buyer verify build quality and run a trial on the actual container before shipment, which is especially valuable for a 150ml lotion bottle or cleanser tube where neck and wall behavior are best judged on real parts. Aibim’s own CNC center means mold and machine adjustments observed during a factory visit can be turned around quickly, reducing the gap between approval and delivery. Wanplas reinforces this with group-level promises on transport, capacity, and quality standards that apply to the Aibim line.
Training and documentation round out the package. Operators learn recipe loading from the SD-card system, basic maintenance of the plasticizing unit and clamp, and the diagnostic routine for common cosmetic-container defects. Because the three models share architecture, training on one Aibim machine largely carries to the others, so a growing plant builds a consistent skill base rather than three separate ones. The remote monitoring channel then keeps the factory’s engineers connected to the line long after commissioning.
Frequently Asked Questions
What output can a 150ml IBM machine deliver?
Hourly output depends on cavitation, resin, and cycle time rather than a single fixed number, but the 150ml class is efficient because compact core rods allow multiple cavities per platen. Aibim machines are built for uninterrupted personal care runs, and the right cavitation is set during configuration against your target annual volume.
Which material works best for body lotion bottles?
HDPE is the most common choice for its soft touch and chemical resistance to emollients, while PP suits cleanser tubes needing higher heat resistance. Clarity grades such as PCTG serve premium looks but require drying. The final pick should be validated against the actual formula.
Can one machine make both bottles and tubes?
Yes. The same Aibim three-station platform serves a 150ml lotion bottle and a facial cleanser tube by swapping cavity tooling and loading the stored recipe. This lets a filler shift capacity between SKUs without re-qualifying a separate process.
How does IBM compare with extrusion blow molding here?
For the 150ml cosmetic format, injection blow molding gives a molded neck, no flash, and no base weld line, removing deflashing and trimming. Extrusion blow molding suits larger or simpler containers, but IBM wins on finish precision and clean-part economics at this size.
What neck finishes are achievable?
Because the neck is injection molded around the core rod, standard cosmetic threads, sealing lands, and inner bores are produced to tight tolerance and pair with pumps, flip caps, and standard closures. Consistent necks cut capper jams on high-speed filling lines.
What utilities and floor space are needed?
The cell needs power, cooling water, and compressed air sized to cavitation, plus a modest floor area thanks to the compact three-station layout. The IBM55 hybrid electric further reduces cooling load. Exact utility ratings are confirmed in the configuration drawing.
How long does a mold changeover take?
Changeover is shortened by the SD-card recipe system and common clamp architecture across Aibim models. Swapping cavity tooling and loading the proven recipe lets a line move from a lotion bottle to a cleanser tube in a planned, repeatable step rather than a long re-tuning session.
Is the machine certified for export markets?
Every Aibim machine is CE certified, with a stripper-station laser sensor and light curtain as standard safety features. This meets the European machinery framework out of the crate, so buyers in regulated markets avoid a separate safety retrofit.
