Our expertise lies in PET preform injection molding. Our R&D team, led by industry veterans including former HUSKY (Canada) senior engineers, as well as experts from China's "Thousand Talents Plan" (Dr. Rong & Dr. Liu), drives innovation in every machine. Whether it's standard models or high-speed production systems, we craft equipment that combines precision, durability, and energy efficiency, outperforming global benchmarks.

We have a global reach with expanding direct EFFICIENT-branded exports worldwide, while ensuring local support for seamless service. No matter if you're a startup scaling up or an industry leader optimizing production, our solutions cater to your needs in diverse sectors.

Take 500/550ml, gram weight 12.8g-16g, and 48-cavity with preform weight 13.5g as an example, The outputcapacity of EFFlCIENT solution is about 20% higher than that of competing products of the same model in the marketThe output of preforms is about 700 kg more per day, and the output of preforms per month is about 21fons. Calculated at a profit of US$80/ton for PET preforms, each month you can have US$1,615 more proft wit EFFICIENT Solution.

1. It adopts a servo system of a world-famous factory-branded high-voltage gear pump with a Japanese or German brand, with high response speed and control accuracy, saving about 30% to 80%.

2. All hydraulic components are made of products from world-renowned manufacturers to ensure the stability and durability of the machine operation.

3. The proportional backpressure control is adopted to make the process adjustment range wider and the product is more stable.

Re-define the PET Preform Injection Molding Machine

As the competition in the PET preform market becomes more and more intense, and the profit becomes less, the transformation and upgrading of the preform production process and cost control have become the top prionty to all PET relevant products manufacturers. The two core factors that restrict the production cost of preforms are the cycle time and energy consumption.Therefore, the requirements for the cycle time and energy consumption of the PET lMM getting higher and higher. Most of the injection molding machines used on the market are from general-purpose lMM, only by simply changing the screw & barrel unit, not specially desgned for PET preform mold and PET material. EFFlCiENT has been focusing on high-speed preform injection molding system for many years, and has successfully developed a series of special PET injection molding machines in an essential sense. These special high speed PET injection molding machines can help our clients solve this difficult problems from the root.
