The 68 mm neck diameter makes this auto blowing machine one of very few in its class capable of producing incision-free easy-open cans automatically — a technically demanding format that traditional machinery handles poorly.

The 4-cavity pet blow molding machine design sustains up to 4,600 bottles per hour under normal operating conditions. Whether you run single-shift or continuous 24-hour production, the output figures hold up under sustained load.

Normal heating power sits at 21 kW against a peak of 62.5 kW, meaning the heating system operates at around one-third capacity during steady-state production. This ratio keeps energy expenditure predictable and overhead low for food packaging operations running extended production windows.

The rigid machine frame, coupled with a precisely tuned clamping mechanism (128 mm stroke, 200 mm close distance), maintains consistent mold alignment across millions of production cycles. Dimensional variation between bottles is kept within tight tolerances — critical for downstream filling and capping equipment.

While PET is the primary material for food containers in this series, the plastic blowing machine platform supports PETG, PC, PCTG, and PP with appropriate tooling and parameter adjustment, giving processors the flexibility to respond to changing packaging specifications or material sourcing conditions.

The engineering behind this fully automatic blow moulding machine series is backed by multiple registered national patents covering the heating system design, mold-clamping mechanism, and preform transfer methodology. These patents reflect years of iterative improvement in production reliability and output consistency.

Preform Injection Mold

• The gate and die-lip assembly uses a dual-component structure that guarantees axial alignment throughout the preform forming stage.
• Cooling channels are routed through calculated paths to maximise heat extraction from each preform, shortening cycle time without compromising structural quality.
• All forming components are produced from imported die steel grade 2316, providing rust resistance and dimensional stability after heat treatment.
• Core plate, cavity plate, and structural components are machined from 420 stainless steel for long-term corrosion resistance.
• Standard interchangeable fittings enable rapid mold servicing with minimal downtime.
• Advanced mold architecture allows a single mold to accommodate more than one preform profile.

Blowing Mold

• All cavity blocks are fabricated from premium-grade alloy steel selected for long fatigue life under high-pressure blowing cycles.
• Bottle geometries are developed using professional 3D CAD/CAE software, allowing complex wide-mouth profiles to be validated digitally before any metal is cut.
• A broad library of validated bottle shapes is available to shorten tooling lead times for customers with defined bottle briefs.
• Water-cooling channels follow an optimised routing pattern to remove heat evenly from the blown bottle, maintaining consistent wall thickness and clarity.
• Every metal component in the mold assembly is finished on CNC machining centers to tight tolerances, ensuring repeatable parting-line quality and surface finish.

Wide-mouth jars blown on this auto pet blowing machine provide an airtight, resealable format that protects dried produce from moisture ingress. The 80 mm body diameter accommodates large pieces without bridging at the neck.

Condiment processors filling products like chilli paste, oyster sauce, and salad dressing benefit from the consistent wall thickness distribution that the stretch-blow process provides, reducing the likelihood of pinhole failures during transport and storage.

PET bottles for edible oil require excellent clarity, structural rigidity under filled weight, and resistance to light exposure. This bottle blow molding machine produces oil-grade containers that meet all three criteria in a single production pass.

This machine is among the first in its category to produce incision-free easy-open plastic cans automatically. The combination of 68 mm neck capability and precise clamping keeps the can rim geometry within specification for standard lid-seaming equipment.

Supplement brands and nutraceutical producers that require tamper-evident wide-mouth containers will find the dimensional repeatability of this fully automatic blow moulding machine directly compatible with child-resistant closure systems and automated filling lines.

Consumers in Colombia, Southeast Asia, and beyond demand food-grade, BPA-free, crystal-clear containers for infant nutrition products. The tight process control of this two-step blow molding machine ensures batch-to-batch consistency and verifiable material purity for regulated markets.

Neck diameter is the deciding parameter for wide-mouth applications. If your container requires a neck of 50 mm or above, you need a dedicated bottle blow molding machine in the HGA.ES series. Standard narrow-neck machines cannot produce these formats reliably.

A pet blow molding machine rated at 4,600 bph on a 4-cavity mold needs to align with your downstream filler, capper, and labeller throughput. Over-specifying creates buffer inventory; under-specifying creates bottlenecks. Use theoretical output figures as a baseline, then apply a 10–15% efficiency factor for real-world conditions.

If your product portfolio includes both PET and PP containers, choose a plastic blowing machine platform that supports both material families through tooling changes rather than full machine replacement. The EP-HGA.ES-4C100 covers PET, PETG, PC, PCTG, and PP.

High-pressure blowing at 35 kg/cm² demands a matched air compressor with sufficient flow capacity. Verify that your plant utility infrastructure — compressed air volume, cooling water flow at 30 ltr/min, and electrical supply — meets the machine specification before finalising your order.

High-pressure blowing at 35 kg/cm² requires a matched air compressor with sufficient flow rate and oil-free output to protect bottle clarity and food-contact compliance. We supply compatible units engineered specifically for pet blowing machine environments.

Stable mold surface temperature is a prerequisite for repeatable bottle wall thickness in any two-stage blow molding machine setup. Our temperature controller units maintain cooling-water temperature within ±0.5°C, directly supporting the 8–12°C cooling specification of the EP-HGA.ES-4C100.

For food-grade and pharmaceutical lines, automated visual inspection at the blow-moulding exit point is increasingly a regulatory and customer requirement. Our inline inspection system detects contamination, deformation, and wall-thickness anomalies at production speed without operator intervention.

We bundle chiller and air compressor packages for customers commissioning complete blow-moulding lines. This combined supply simplifies procurement, ensures hardware compatibility, and gives our engineering team a single point of accountability for utility performance across the full blow molding machine installation.
