EP-HGA.AS-2C114.3 Автоматты ПЭТ үрлеу машинасы — 1000 мл, 2 қуысты, косметикалық және фармацевтикалық бөтелкелер

Half-Preblowing (AS) Structure

The AS-series half-preblowing mechanism expands the preform in a controlled intermediate stage before full pressure blow, resulting in more uniform radial wall thickness — especially critical for narrow-neck pharmaceutical and cosmetic containers where standard RSBM machines show measurable wall variation.

International-Grade Servo Drive System

Equipped with internationally recognised servo motors and precision reducers, the drive system provides consistent torque and speed across all clamping, stretching, and blowing motion axes. Energy consumption is significantly lower than hydraulic-dominant systems of comparable output.

High-Precision Neck-Finish Tolerance

The machine is designed to maintain strict neck-finish dimensional tolerances across both cavity positions, supporting compatibility with precision closure systems used in pharmaceutical dispensers, eye-drop applicators, and high-end cosmetic dispensing caps.

Digital Infrared Heating System

The digital infrared preform heating system provides zone-by-zone temperature control along the preform body, enabling precise thermal profiles for challenging bottle geometries including narrow shoulders, long necks, and asymmetric wall distributions.

Zero Hand-Contact Automated Output

From preform loading through finished bottle discharge, the EP-HGA.AS-2C114.3 operates as a fully sealed automated system. No manual intervention occurs at any stage of bottle formation, supporting compliance with pharmaceutical GMP and food-contact hygiene requirements.

AS vs. ES: Understanding the Difference

Buyers evaluating the AS series alongside the standard ES series should note the structural difference: ES machines use a direct single-blow sequence; AS machines insert a controlled half-preblow stage. For small-diameter, high-precision containers, AS delivers a measurable quality advantage. For larger-diameter, higher-volume standard containers, ES machines offer greater throughput efficiency. See our full RSBM machine range for a direct comparison.

Фармацевтикалық қаптама

Oral liquid bottles, syrup bottles, eye-drop containers, nasal spray bottles, and medical dropper containers requiring tight neck-finish tolerances and wall-thickness uniformity. The AS structure is particularly suited to narrow-neck pharmaceutical bottles where a standard single-blow sequence produces measurable wall variation.

Cosmetic & Personal Care

High-clarity serum bottles, toner bottles, essence flacons, lotion dispensers, and premium skincare packaging where optical clarity and surface finish consistency are non-negotiable. The half-preblowing structure achieves superior clarity on PET and PETG substrates compared to direct-blow equivalents.

Application: Oral antibiotic liquid bottles (60ml and 100ml) with 28mm neck finish for child-resistant closures.

Problem solved: The facility had previously used a standard ES-type RSBM machine and experienced consistent rejection rates above 3% due to wall thinning at the bottle shoulder — a critical failure point for pressure-tested pharmaceutical containers. Switching to the AS-series half-preblowing architecture reduced rejections to below 0.4% within the first month of operation.

“The wall thickness improvement was immediate and measurable. Our QC team confirmed that shoulder thickness variance dropped from 0.18mm average to under 0.06mm. For our GDA audit, this was the data we needed.”

Application: PETG serum flacons (30ml, 50ml) for a domestic premium skincare brand producing for both local retail and export to South Korea.

Problem solved: The brand required a specific optical clarity target — bottles needed to appear glass-equivalent on shelf. Previous PET machines produced flacons with visible haze at the base due to insufficient preblowing. The AS structure eliminated the haze entirely on the PETG substrate at their specified bottle weight.

“Our retail buyer in Seoul commented that the bottle clarity was indistinguishable from glass in their product photography. That was a direct result of switching to the AS machine.”

Application: LDPE-equivalent narrow-neck eye-drop bottles (5ml, 10ml) with 13mm neck diameter requiring precise dropper-tip compatibility.

Problem solved: Existing equipment produced inconsistent neck ovality at the 13mm neck diameter — dropper tips failed the leak test at a rate of approximately 1 in 80 bottles. The AS-series neck precision reduced dropper-tip leak failures to 1 in over 2,000 bottles under identical test conditions.

“For eye-drop containers, a failed seal is not just a quality issue — it is a patient safety issue. The neck-finish precision of this machine solved a problem we had been working around for two years.”
