Blow Molding Solutions for Every Packaging Application
Two machine families โ the EP-ZQ European-style IBM series and the EP-HGY one-step ISBM series โ cover pharmaceutical vials, cosmetic flacons, baby bottles, daily-chemical containers, wide-mouth jars, water barrels, and industrial packaging.
Why a Solution-First Approach
Match the Right Machine to Your Bottle โ Before You Buy
Selecting the wrong blow molding technology โ or the wrong model within the right technology family โ is the most expensive mistake a packaging procurement team can make. A machine that is under-specified cannot meet your output targets. A machine that is over-specified ties up capital in capability you will never use. And a machine that is technically mismatched to your resin, bottle geometry, or neck finish specification creates quality problems that compound with every production run.
Ever Power manufactures both injection blow molding (IBM) and one-step injection stretch blow molding (ISBM) machines in our own 20,000 mยฒ factory. Our engineering team's understanding of both processes means we will always recommend the technology that actually fits your application โ including recommending the alternative if your initial specification points to the wrong process.

What We Produce
Container Types Across Both Machine Families
The EP-ZQ IBM and EP-HGY ISBM machine families together cover every hollow plastic container type from 1 ml laboratory vials to 20 L industrial barrels.
How It Works
The Two Production Processes โ In Plain Engineering Terms
The right process choice is the foundation of every successful packaging machine investment. The four sections below explain both processes and provide the technical comparison and selection criteria needed for procurement and engineering team decision-making.
One-Step ISBM Process
The one-step ISBM process consolidates three historically separate operations โ injection molding, thermal conditioning, and stretch blow molding โ into a single continuous automated cycle without any secondary reheating step. This eliminates up to 40% of energy consumption versus two-step RSBM and provides superior biaxial molecular orientation for barrier and strength properties.
Click each stage to expand the technical detail.
European IBM Process
Injection blow molding is a closed-loop 3-station rotary process without a stretch step. HDPE, PP or PS resin is injection-molded around a core pin at Station 1, forming the preform and the finished bottle neck finish simultaneously to closure-compatibility tolerance. The EP-ZQ European-style IBM machines operate at 20โ30% higher clamping force than Chinese-market alternatives at each tonnage tier.
3-Station Rotary Architecture
Injection โ Blow โ Stripping operates simultaneously every cycle. All three stations fire in parallel โ maximum output efficiency, minimum idle time. No separate conditioning station needed.
Zero Flash ยท Zero Scrap
Because IBM injects directly onto the core rod, there is no parison and no flash generated at any stage. 20โ40% material savings versus EBM. No flash trimming equipment, no trim scrap management required.
HDPE ยท PP ยท PS ยท PCTG ยท EVA Resins
IBM excels with resins that cannot be stretch-blown effectively. HDPE, LDPE, PP, PS, PCTG and EVA are the standard IBM resin families โ covering pharmaceutical, daily-chemical, food and specialty applications.
Up to 30 Cavities at 10 ml
The EP-ZQ135 flagship delivers up to 30 cavities at 10 ml per cycle. Independent hydraulic double system from EP-ZQ80 upward eliminates inter-cavity weight variation. Weight consistency typically within ยฑ1% across all cavities.
ISBM vs IBM vs EBM
Ten key performance dimensions across the three primary blow molding processes. Both IBM and ISBM are Ever Power product lines โ EBM is included for reference as the process most commonly displaced when customers switch to injection-based technology.

Frequently Asked Questions
Solutions & Application Questions
Questions procurement managers and engineers ask most frequently when evaluating blow molding technology options. For questions specific to your bottle design or production target, contact our engineering team directly.
I currently run an extrusion blow moulding line. What does converting to IBM or ISBM give me?+
Switching from EBM to IBM or ISBM typically delivers: elimination of flash scrap (20โ40% material saving per cycle), elimination of flash trimming labour and equipment, improvement in bottle weight variation from approx. 3% to approx. 1%, improvement in neck-finish consistency, and reduction in per-bottle energy consumption. For PET containers, ISBM also adds biaxial molecular orientation โ delivering superior oxygen barrier, compression strength and optical clarity that EBM cannot achieve in PET at equivalent wall thickness.
I have existing ASB-12M moulds. Can I use them directly on an Ever Power ISBM machine?+
Yes. The EP-HGY150-V4 and EP-HGY150-V4-EV are engineered for direct mechanical compatibility with the Japanese ASB-12M mould format. The injection station platen dimensions, tie-bar spacing and blow station geometry match ASB-12M standard specifications โ enabling direct mould installation without adaptation fixtures. We recommend sharing your specific mould drawings with our engineering team before finalising the purchase order.
What is the minimum viable cavity count for a commercially competitive IBM or ISBM line?+
There is no universal minimum โ the commercially viable cavity count depends entirely on your target output per hour, your bottle size, and your cycle time. A 1-cavity EP-HGY650-V4 running 18.9 L water barrels at a 50-second cycle time is fully commercially competitive for a water barrel production operation. Contact us to provide your production plan and we will confirm whether the proposed cavity count is correct.
Can the same machine produce different bottle sizes by changing moulds?+
Yes. Both IBM and ISBM machines are designed for mould changeover between different bottle SKUs. The machine parameters are stored as recipes in the PLC and recalled at the start of each production run. Physical mould changeover time is typically 1โ4 hours depending on machine size and operator experience. The constraint is that the new mould must be within the machine's physical stroke and platen dimensions.
What does "GMP compliant production" mean in practice for a blow moulding machine?+
GMP compliance for a blow moulding machine specifically means: (1) zero human hand contact with the bottle at any stage; (2) documented and traceable process parameters for every production batch; (3) consistent, verifiable dimensional output across all cavities in the mould; and (4) validated machine qualification documentation (IQ/OQ/PQ basis). The EP-HGY full-servo EV series and EP-ZQ IBM series satisfy all four requirements.
What utility connections does an IBM or ISBM machine require?+
All Ever Power IBM and ISBM machines require: (1) Power supply โ 370โ400V / 3-phase / 50 Hz, connected load varies by model from approx. 20 KW (EP-ZQ40) to 112.8 KW (EP-HGY150-V4-EV); (2) High-pressure compressed air โ 2.0โ3.5 MPa for ISBM blow air and 0.5โ0.7 MPa for IBM and pneumatic ancillaries; (3) Cooling water โ inlet pressure 0.4โ0.6 MPa, temperature below 25 degrees C; (4) Floor loading capacity โ minimum 2 T/mยฒ beneath the machine footprint, up to 5 T/mยฒ for the EP-HGY650-V4. Detailed utility specification sheets and installation drawings are provided upon order confirmation.
