Medicine Bottle Series Blow Molding Machine
9 fully automatic two-step PET stretch blow molding machines — from 2-cavity compact models to 6-cavity high-output configurations — covering every pharmaceutical bottle format from small eye drop vials to large hospital supply dispensing containers.
Medicine Bottle Series Overview
Korea Ever-Power's Medicine Bottle Series covers nine fully automatic two-step blow molding machines for pharmaceutical-grade PET, PETG, and PP bottle production — from 2-cavity 2,000 BPH entry models to the 6-cavity 7,200 BPH high-output configuration, in two sub-series:
Established cam-driven blow station. Two models: AS-2C114.3 (2,000 BPH / 1,000 ml) and AS-4C76.2 (4,000 BPH / 500 ml). Preferred when a reliable, cost-efficient cam-driven platform is the selection criterion.
Next-generation servo-driven blow station — precise stretch-rod control, repeatable positioning, faster changeover. Seven models from ES-2C100 to ES-6C76. The choice for tight wall thickness tolerances or frequent format switching.
All 9 Models at a Glance
Three parameters determine the right model: container body diameter (sets minimum pitch), required BPH (sets cavity count), volume (confirms ceiling). Start with body diameter.

Choose AS when cam-driven architecture is acceptable, BPH target is 2,000–4,000, or capital cost is the primary criterion.
Choose ES when wall thickness tolerance is tight, the line runs multiple SKUs with frequent mold changeover, or upgrading from AS on the same pitch.

Why Two-Step Blow Molding for Pharmaceutical Bottles?
Pre-made PET/PETG preforms are reheated through infrared oven zones and stretch-blown into finished containers — delivering three key advantages for pharmaceutical packaging:
✓ Consistent wall thickness — reheating stabilises crystallinity before blowing, producing more uniform material distribution than one-step ISBM
✓ Format flexibility — changing the blowing mold changes the container without touching preform tooling; multiple SKUs share the same preform stock
✓ Clean production — no injection molding in the blowing room; two-step layout is compatible with GMP clean-room requirements

What is the difference between the AS and ES series?
The AS series uses a cam-driven blow station — proven architecture in 2 models. The ES series uses a servo-driven blow station delivering more precise stretch-rod control, repeatable cavity-level positioning, and faster changeover. Choose ES when wall thickness tolerance is tight or the line runs multiple SKUs with frequent mold changeover.
Which model should I choose for eye drop vials and small pharmaceutical dropper bottles?
For small-mouth vials (18–38 mm neck): the ES-3C76 is purpose-built at 3,000 BPH. For higher throughput: ES-4C76 (4,800 BPH) or AS-4C76.2 (4,000 BPH). The ES-3C76's narrow neck specialisation covers eye drop formats that wider-neck machines cannot serve.
Is an oil-free compressor required for all models?
Yes. All nine models require an oil-free air compressor — oil contamination in blowing air would compromise container hygiene and fail pharmaceutical packaging compliance. High-pressure air consumption ranges from 1,000 L/min (ES-2C100) to 5,800 L/min (ES-6C76).
Does Korea Ever-Power supply molds for all nine models?
Yes. Korea Ever-Power designs and manufactures matched blowing molds and preform injection molds for all nine models. Submit your container specification — body diameter, neck finish, height, volume, material, wall thickness targets — for mold feasibility review and pricing.
What materials can these machines process?
All nine models support PET, PETG, and PP. PETG is commonly specified for amber tinted pharmaceutical vials providing UV protection. PP suits containers requiring greater chemical resistance. Infrared oven zones are independently adjustable for each resin type.
I'm not sure which model fits — what should I send Korea Ever-Power?
Body diameter, neck finish diameter and thread standard, container height, volume, material (PET/PETG/PP), required BPH, and annual production target. Our engineers confirm the correct model, pitch compatibility, mold feasibility, and auxiliary equipment specification within 2 business days.
