How It Works
One-Step ISM Process: Three Stations, One Continuous Cycle
The ISM (Injection Blow Molding) process integrates preform injection, blow molding and bottle ejection onto a single rotating machine. All three stations operate simultaneously — so output rate is governed only by injection time, not the sum of all three stages.
Plastic is injected into the mold under controlled pressure. The bottle neck, thread and preform geometry are formed here. After the mold opens, the mandrel rotates 120° to Station 2 via the precision angle divider.
The hot preform is inflated by compressed air through the mandrel core. The blow mold cavity determines final bottle shape, diameter and height. The mold opens and the turret advances to Station 3.
Finished bottles are stripped and discharged onto the conveyor. Since all three stations run in parallel, one complete set of bottles is produced every cycle — no deflashing, no reheating, no trimming required.
Three-Station Rotary Principle: Station 1 Injection - Station 2 Blow - Station 3 Stripping

Technology Overview
ISM Machine vs. ISBM Machine — What Is the Difference?
EVER POWER manufactures both ISM machines (Injection Blow Molding) and ISBM machines (Injection Stretch Blow Molding). Both start with injection molding, but the downstream forming and target applications differ substantially.
| Item | ISM Machine (IBM) | ISBM-machine |
|---|---|---|
| Process | Inject preform — blow directly on mandrel. No stretch rod. | Inject preform — reheat — stretch axially with rod — blow to shape. |
| Materials | HDPE, LDPE, PP, PS, ABS, EVA, PCTG, bio-resin | PET primarily. Also PP, specialty resins. |
| Containers | Pharma vials, eye drops, cosmetic jars, cream bottles, 1ml–2000ml | PET water/juice/CSD bottles, 300ml–2L+ |
| Neck precision | Extremely high — within 0.1mm, no flash, no parting line | High — neck formed at injection stage |
| GMP suitability | Excellent — closed one-step process. EP60HE GMP cleanroom ready. | Good — multi-step requires more cleanroom planning |
| Scrap | Zero | Minimal gate vestige possible |
| Best for | Pharma, cosmetic, baby, daily chemical containers in PP/HDPE/LDPE/PS/PCTG | PET beverage bottles, high-clarity PET jars |
EVER POWER manufactures both ISM and ISBM machines. For PP, HDPE or LDPE pharmaceutical and cosmetic containers — ISM is the right choice. For clear PET beverage bottles — contact us to discuss ISBM options. Send us your bottle drawing and we will confirm the correct technology in writing.
EVER POWER ISBM Machine (EPY Series)
Oil-Free Screw Air Compressor for IBM Lines
In addition to ISM machines and IBM molds, EVER POWER also supplies oil-free screw air compressors — a critical utility component for any injection blow molding production line. The ISM machine requires a continuous, clean compressed air supply at 0.7–1.2 MPa for the blow molding station. Oil contamination in the air supply is a direct cause of bottle surface defects and failed pharmaceutical packaging inspections.
Our oil-free screw compressors are specifically matched to EP series ISM machine air consumption requirements, delivering clean, dry compressed air without risk of oil carry-over. Sourcing the compressor from EVER POWER with the machine eliminates the compatibility and sizing risks that arise when assembling third-party equipment.

FAQ
ISM Machine Common Questions
What is an ISM machine?
An ISM machine (Injection Blow Molding machine, also called IBM machine) is a one-step hollow container forming machine. It combines preform injection, blow molding and bottle ejection in a single three-station rotating machine. Unlike EBM (Extrusion Blow Molding), the IBM process produces zero flash, uniform wall thickness and a precision-formed neck thread — making it the standard equipment choice for pharmaceutical and cosmetic container production where neck accuracy is mandatory.
What is the difference between ISM and ISBM machines?
ISM (IBM) inflates the preform directly without a stretch rod — used for PP, HDPE, LDPE, PS, PCTG containers in pharmaceutical, cosmetic and daily chemical applications. ISBM adds an axial stretch rod before blowing, enabling biaxial molecular orientation — used for PET water, juice and CSD bottles. EVER POWER manufactures both. If your project involves PP or HDPE pharmaceutical bottles, ISM is correct. For clear PET beverage bottles, contact us to discuss ISBM.
What materials can EVER POWER ISM machines process?
All EP series ISM machines process HDPE, LDPE, PP, PS (including lactic acid bacteria transparent PS), ABS, EVA, PCTG and bio-based corn material. The EP135 with 6+N barrel zones and 70mm screw at 22:1 L/D also processes PC and PETG engineering resins. Confirm material compatibility with our team before ordering for non-standard compounds.
How do I select the correct ISM machine model?
Three calculations: (1) Total shot weight needed = preform weight × cavities — must be below the model injection weight. (2) Required cavities = target output per hour ÷ (3600 ÷ cycle time). (3) Mold platen fit — your cavity array must fit within the model maximum platen size. Send us your bottle drawing, production target and material and our team will confirm the correct model in writing.
Can the ISM machine meet pharmaceutical GMP requirements?
Yes. The one-step IBM process keeps the container in a closed cycle — no inter-machine transfer, no contamination risk. The EP60HE fully electric model features zero lubricant above the mold area (bottom-up design), fully meeting pharmaceutical hygiene standards. All EP series machines can be configured with stainless steel enclosures for cleanroom Class 100,000 installation. EVER POWER provides equipment documentation to support IQ/OQ/PQ validation.
Do you also supply the oil-free screw air compressor for the IBM line?
Yes. EVER POWER supplies oil-free screw air compressors matched to EP series ISM machine air consumption requirements (0.7–1.2 MPa, 0.7–0.8 M3/min). Sourcing the compressor with the machine eliminates compatibility and sizing issues. Oil-free design ensures no oil carry-over risk to bottles — essential for pharmaceutical and food-grade packaging. Contact us to include the compressor in your production line quotation.
