Medicine Bottle Blow Molding Machine

Start with your largest container in the product range. If your maximum volume is 500 ml or below with a body diameter under 60 mm, the 2-cavity HGA.ES compact configuration is the natural fit. Containers from 500 ml to 1000 ml with wider body diameters point toward the HGA.AS standard or the HGA.ES large-cavity series. Bottles above 1000 ml and up to 1500 ml fall in the HGA.ES XL 2-cavity range.

Neck size is often the determining constraint. Sub-10 mm neck finishes — used in eye drop and nasal spray bottles — require a machine specifically built for small-tooth-mouth operation. The 7 mm automatic configuration is unique to this series. For necks in the 18–38 mm range typical of syrup and wash bottles, the 3-cavity or 6-cavity HGA.ES models deliver maximum output efficiency.

PET is the default choice for most pharmaceutical bottles and is widely approved under international pharmacopeial standards. PETG is preferred for pediatric and ophthalmic applications because of its better drop resistance and compatibility with lower-temperature sterilization. If your packaging specification references a specific resin grade by code, confirm this with the machine supplier at the quotation stage — mold material and process settings are resin-specific.

Each machine requires a compressed air supply (low-pressure circuit at 7 kg/cm², high-pressure blowing at 26–35 kg/cm²), a cooling water circuit operating at 5–6 kg/cm² with flow rates of 30–40 ltr/min, and electrical supply matched to the machine’s heating power (33–62.5 kW maximum). Facilities in Colombia, Southeast Asia, and the Middle East often run shared utility infrastructure — verify your existing capacity against the machine’s peak demand before specifying a model.
