Energy-saving effect, after the market trial operation, compared with the traditional PET IMM, EFFICIENT PET injection molding machine not only increases the production capacity of the whole line, but also effectively increases the energy saving by more than 15%.

The actual energy consumption per ton of PET material of most traditional PET IMM on the market is about 500 degrees; however, EFFICIENT machines have undergone a series of upgrades and improvements, and measured by the actual use of end clients, each ton of PET material can save about 70 degrees. Calculated according to the electricity cost of 0.13 USD/Kwh, the electricitly cost can be saved by about 9.2 USD per ton. According to the average daily consumption of 4.18 tons of raw materials, the daily energy consumption cost can be saved by 38,46 USD/day.

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.

Application Needs Recommended Series Core Reason
Large-scale, high-intensity production (e.g., 500ml water bottle preforms) HPET Series Designed specifically for high-speed cycles to maximize output per unit time and reduce unit cost.
Diversified, medium-scale production (e.g., cosmetics containers, pharmaceutical bottles) KPET Series Modular design enables fast mold changes, with excellent energy efficiency in non-continuous production.
Extra-large neck diameter and special preforms (e.g., wide-mouth jars, deep-cavity bottles) KPET Custom Machine Features a larger mold opening stroke and special mold-locking structure to accommodate complex mold requirements.
1. What products can this machine produce?
This solution is designed for high-performance packaging production and can be configured for PET preforms or selected PE/PP applications depending on the machine type and project requirement.
2. Which applications are suitable for?
Depending on the project configuration, this solution can support water and beverage preforms, edible oil packaging, daily chemical containers, wide-mouth packaging, and 3–5 gallon preform applications.
3. How do I know whether this machine is right for my production target?
The right model depends on your product type, material, cavity requirement, output target, and future expansion plan. Our team can recommend a suitable configuration based on your production goals.
4. How does this machine improve production efficiency?
