Three machine families — the EP-ZQ European-style IBM series, the EP-HGY one-step ISBM series, and the EP-HGA reheat stretch blow molding (RSBM) series — cover pharmaceutical vials, cosmetic flacons, baby bottles, daily-chemical containers, water and beverage bottles, wide-mouth jars, water barrels, and industrial packaging.
Why a Solution-First Approach
Selecting the wrong blow molding technology — or the wrong model within the right technology family — 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 injection blow molding (IBM), one-step injection stretch blow molding (ISBM), and reheat stretch blow molding (RSBM) machines in our own 20,000 m² factory. Our engineering team's understanding of all three processes means we will always recommend the technology that actually fits your application — including recommending the alternative if your initial specification points to the wrong process.

Each industry solution matches container requirements to the specific machine platform, station configuration, resin family, and cavity count that delivers the best combination of quality, output, and cost-per-bottle. Our engineering team provides free feasibility assessment for any application listed below — contact us with your bottle drawing and target output.
Oral liquid vials, tablet and capsule bottles, eye-drop containers, nasal-spray bottles and infusion packaging in HDPE, PP, PET and PETG. Both the EP-ZQ IBM and EP-HGY ISBM series operate with zero human hand contact throughout the production cycle, directly supporting GMP manufacturing practice requirements. Neck finish is formed to closure-compatibility tolerance in the injection mould — no secondary trimming or machining required.
High-clarity serum flacons, lotion dispensers, perfume bottles and complex-profile cosmetic containers in PET, PETG, Tritan and PCTG. The one-step ISBM process produces bottles with optical clarity approaching glass. Neck-diameter tolerance is held to ±0.05–0.10 mm. The full-servo EP-HGY150-V4-EV is specified by premium brands requiring GMP documentation and PLC-based parameter traceability.
Shampoo, body-wash, fabric conditioner, hand-wash and household cleaning product containers from 100 ml to 2,000 ml in HDPE, PP and PET at high cavity counts. The EP-ZQ IBM series reaches up to 30 cavities at 10 ml — the standard platform for FMCG daily-chemical mass production. For PET containers requiring clarity or higher barrier performance, the EP-HGY ISBM series provides superior output per machine.
BPA-free baby bottles and infant feeding accessories in PC, Tritan and PP requiring exceptional optical clarity, autoclave sterilisation compatibility, and fully automated zero-contact production. The one-step ISBM process provides GMP-level contamination exclusion. Neck dimension consistency is critical for teat-to-bottle sealing — ISBM delivers this within ±0.05 mm across all cavity positions.
Mineral water bottles, juice containers, condiment jars, cooking oil bottles and wide-mouth food canisters in PET from 100 ml to 2,500 ml. The biaxial molecular orientation of the ISBM process delivers significantly superior gas barrier performance and compression strength compared to extrusion blow moulded containers of equivalent wall thickness — extending shelf life and enabling lighter-weight containers.
Cosmetic cream jars, protein powder containers, vitamin and mineral supplement bottles and food condiment wide-mouth jars requiring neck diameters exceeding 60 mm. The EP-HGY200-V4-B with AOKI-250 mould compatibility and 600 mm upper mould stroke is the dedicated solution for tall wide-mouth profiles. The EP-HGY250-V4 with ASB-70DPH compatibility handles the largest-diameter formats up to 200 mm body diameter.
Asymmetric bottles, art-glass-effect containers, gift packaging bottles, multi-faceted cosmetic containers and novelty craft containers. The one-step ISBM process is uniquely capable of reproducing complex non-round and asymmetric bottle profiles that two-step reheat stretch blow machines cannot achieve consistently — because the preform never leaves the machine between injection and blow, eliminating thermal distortion.
5 L, 10 L, 18.9 L (5-gallon) and 20 L drinking water barrels and large-format industrial containers in PET and PETG. The EP-HGY650-V4 is the only machine in the EP-HGY range engineered specifically for this application — with 400 KN dual clamping force, a 1,070 mm upper mould stroke, and a maximum single-bottle weight of 900 g. ISBM-produced water barrels deliver substantially superior optical clarity, wall-thickness uniformity, and oxygen barrier performance versus EBM equivalents.
The EP-HGA RSBM series covers nine application industries across 28 machine configurations — AS series pharmaceutical precision, ES series multi-industry (2–8 cavities, 500 ml–5 L), FS series wide-mouth and special-shaped, JS series large-capacity (5 L), and JS-2C366 / J-2C366 for 20 L water barrel and edible oil barrel production. All models process PET in a fully automatic two-step cycle with zero hand contact and servo drive. CE certified. For operations where high-volume single-format PET production requires maximum throughput, the RSBM process — and specifically the EP-HGA ES-8C76 at 8 cavities — is the definitive solution.
What We Produce
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 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.
The one-step ISBM process consolidates three historically separate operations — injection molding, thermal conditioning, and stretch blow molding — 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.
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 20–30% higher clamping force than Chinese-market alternatives at each tonnage tier.
Injection → Blow → Stripping operates simultaneously every cycle. All three stations fire in parallel — maximum output efficiency, minimum idle time.
Because IBM injects directly onto the core rod, there is no parison and no flash generated at any stage. 20–40% material savings versus EBM.
IBM excels with resins that cannot be stretch-blown effectively. HDPE, LDPE, PP, PS, PCTG and EVA are the standard IBM resin families.
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.
Reheat stretch blow molding (RSBM) separates the production process into two independent stages. Stage one: preform injection molding on a dedicated injection machine or purchased as ready-made preforms. Stage two: preforms are reheated and biaxially stretch-blown into finished bottles on a standalone EP-HGA RSBM machine. This two-step approach allows the RSBM machine to run at maximum output continuously without being limited by a co-located injection cycle — enabling higher per-line throughput at scale versus one-step ISBM.
Stage 1: preforms injected separately or purchased ready-made. Stage 2: EP-HGA RSBM machine reheats and biaxially stretch-blows the preform into the finished bottle. The two stages run independently — the blow machine is never waiting for an injection cycle.
The ES-8C76 at 8 cavities is the highest-output machine in the EP-HGA range — the definitive platform for water bottling plants and beverage operations requiring maximum throughput from a single machine installation at the 700 ml format.
All EP-HGA RSBM machines process PET: standard food-grade IV 0.76–0.84 dl/g for water and beverage, pharmaceutical-grade for medicine bottles (AS series), food-contact grade for edible oil and food containers.
Water & beverage · cosmetic & daily chemical · pharmaceutical · food · edible oil · chemical & pesticide · baby bottle & PP · large barrel (5L–20L) · special-shaped & craft bottle. One machine family covers all nine.

Frequently Asked Questions
Questions procurement managers and engineers ask most frequently when evaluating blow molding technology options. Contact our engineering team directly for questions specific to your bottle design.
Switching from EBM to IBM or ISBM typically delivers: elimination of flash scrap (20–40% material saving per cycle), elimination of flash trimming labour, 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 delivering superior oxygen barrier, compression strength and optical clarity that EBM cannot achieve at equivalent wall thickness.
Yes. The EP-HGY150-V4 and EP-HGY150-V4-EV are engineered for direct mechanical compatibility with the Japanese ASB-12M mould format. We recommend sharing your specific mould drawings with our engineering team before finalising the purchase order.
There is no universal minimum — the commercially viable cavity count depends entirely on your target output per hour, your bottle size, and your cycle time. Contact us to provide your production plan and we will confirm whether the proposed cavity count is correct.
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 1–4 hours.
GMP compliance for a blow moulding machine 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; and (4) validated machine qualification documentation (IQ/OQ/PQ basis). The EP-HGY full-servo EV series, EP-ZQ IBM series, and EP-HGA AS series satisfy all four requirements.
All Ever Power IBM and ISBM machines require: (1) Power supply — 370–400V / 3-phase / 50 Hz; (2) High-pressure compressed air — 2.0–3.5 MPa for ISBM blow air; (3) Cooling water — inlet pressure 0.4–0.6 MPa, temperature below 25 degrees C; (4) Floor loading capacity — minimum 2 T/m². Detailed utility specification sheets are provided upon order confirmation.
