Key Advantages of This Blow Molding Machine
What sets this fully automatic blow moulding machine apart is the integration of engineering precision with operational simplicity. The infrared preform heating system uses segmented zone control, so wall temperature distribution can be fine-tuned for different preform geometries without swapping hardware. The high-pressure blowing circuit, rated at 26–35 kg/cm², ensures full mold fill even in long, slender bottle bodies, while the low-pressure circuit handles mechanical actuation efficiently — keeping the air compressor load balanced and power consumption predictable. Below is a summary of the core structural and performance advantages built into this pet blowing machine.
Two cavities per cycle maximise throughput for compact-footprint lines. Ideal for medium-scale water and beverage bottling operations that need reliable output without a large machine investment.
Normal heating power runs at just 8–12 kW despite a peak rated capacity of 34 kW, meaning the oven zones adapt dynamically to actual production throughput — cutting utility costs significantly over long shifts.
The 110 mm clamping stroke combined with a 280 mm mold-open distance provides ample clearance for bottle extraction while maintaining structural rigidity during the high-pressure blow phase.
Cooling water maintained at 8–10°C at 30 ltr/min flows through optimised mold channels, solidifying bottle walls uniformly and enabling faster cycle times without sacrificing dimensional stability.
All high-wear components — including the stretch rod assembly and mold clamping guides — are manufactured from hardened alloy steel with surface treatments that resist wear, corrosion, and fatigue over millions of cycles.
At 2900×1525×1930 mm and 2,000 kg, this plastic blow molding machine fits comfortably in standard production halls without requiring reinforced flooring or heavy crane installation procedures.

How to Choose the Right Blow Molding Machine
Selecting the appropriate blow molding machine for your operation is a decision that impacts output quality, operating cost, and product range flexibility for years. The key variables to evaluate are container volume, required throughput, material compatibility, and whether a one-step or two-step process better fits your supply chain model. For water and beverage producers working with standard PET preforms and container volumes up to 500 ml, a two-step blow molding machine like the EP-HGA.ES-2C100 is typically the most economical and flexible choice. You gain the ability to source preforms from multiple suppliers, adjust preform weight independently of the blowing line, and run the blowing station at full capacity without being constrained by an integrated injection unit's cycle time.
For operations that require faster mold changeovers, consider cavity count carefully. A two-cavity machine like this model delivers 2,400 bph — adequate for small-to-medium lines. If demand grows, the same mold engineering and production know-how scales directly into higher-cavity models within the same series. Evaluate also your utility infrastructure: this auto pet blowing machine requires a high-pressure air supply at 26–35 kg/cm², which means a compatible industrial air compressor is a critical ancillary investment. The cooling water system at 5–6 kg/cm² and 8–10°C also calls for a properly sized chiller unit to maintain consistent bottle quality across shifts. For Colombian and South American markets where ambient temperatures vary significantly by season, chiller sizing should include a thermal margin of at least 20% above calculated heat load.

常见问题解答
What are the main steps involved in the two-stage blow molding process for producing PET water bottles?
In two-stage, or two-step blow molding, the process is divided into two independent phases. First, PET resin is injection-molded into an intermediate preform at a dedicated injection station. These preforms are then cooled, inspected, and stored until needed. In the second stage — handled by machines like the EP-HGA.ES-2C100 blow molding machine — the preforms are reheated in an infrared oven to a precise orientation temperature, stretch-rods extend them axially, and high-pressure air at 26–35 kg/cm² expands them against a blowing mold cavity to form the final bottle shape. This separation of stages allows each process to be independently optimized for throughput, energy consumption, and quality control.
Which types of PET bottles for water and beverage applications can this fully automatic blow moulding machine produce?
The EP-HGA.ES-2C100 blow molding machine is designed to handle a variety of PET bottle formats within its container specification range — up to 500 ml volume, 80 mm body diameter, and 200 mm height. This covers standard still water bottles (200 ml, 330 ml, 500 ml), sports drink containers, juice bottles, and ready-to-drink beverage formats. The machine can also be mold-configured for oval and contoured body profiles if brand differentiation is a priority. Neck diameters of up to 68 mm accommodate standard 28 mm and 38 mm closure systems commonly used in global beverage markets, including Colombia and South America.
How does a two-stage blow molding machine differ from a single-stage machine when producing PET beverage bottles at scale?
In a single-stage machine, injection of the preform and blowing of the bottle happen in one integrated cycle on the same equipment. This reduces material handling but ties the speed of the injection process to the overall output rate. A two stage blow molding machine like the EP-HGA.ES-2C100 separates the two operations: preforms can be purchased or produced in bulk, stored, and fed into the blowing station at a rate that is independent of injection cycle time.
What auxiliary equipment does a beverage bottling plant in Colombia or South America need to run this pet blow molding machine reliably?
Operating this automatic pet blowing machine in a tropical or subtropical environment — typical in Colombia and much of South America — requires careful sizing of ancillary systems. You will need an oil-free high-pressure air compressor capable of sustaining 1,000–1,400 ltr/min at 26–35 kg/cm² under ambient temperatures that may reach 30–35°C. An industrial chiller sized to supply 30 ltr/min of 8–10°C cooling water is essential; tropical ambient conditions require a chiller with at least 20% thermal reserve above design load. A mold temperature controller adds an additional layer of process stability.
How can beverage producers reduce energy consumption when operating a blow molding machine on a continuous multi-shift production schedule?
The EP-HGA.ES-2C100 is designed with energy efficiency as a core operating principle. Its normal heating power runs at 8–12 kW, well below the rated 34 kW peak, because the infrared heating zones modulate automatically based on the preform feed rate and process temperature feedback. To further reduce energy use on continuous shifts, operators can: schedule preform feed consistently to avoid oven zone overshooting; ensure cooling water temperature is stable at 8–10°C so mold cycles complete at the designed dwell time without extensions; keep high-pressure air receivers properly sized to avoid compressor short-cycling; and conduct regular maintenance on heat exchangers, heating lamps, and cooling channels to maintain system efficiency at rated design levels throughout a multi-shift schedule.
