PET Injection Molding Machine manufacturers

Specilizing in PET Series of injecton molding machine
1. Super energy saving, output power varies with load, and no energy is wasted, in the holding pressure phase, the servo motor will reduce speed with low energy consuption; during the cool down period, the motor does not work, with zero power consumption, compared with the ordinary injection molding machines, it can save 20% to 80% of the power.
2. High precision and high stability, Equipped with the precise pressure sensor and rotary encoder, it can respectively monitor and feed back on the flow and pressure. Based on the feedback, the high performance synchronous servo motor will adjust flow and pressure accordingly by changing the speed and torque. The closed-loop control can ensure the stability of product quality.
3. High response and High efficiecy, the driving system responsed with high sensitivity. It take only 0.05 seconds to reach maximum value. The response speed is much faster than the ordinary injection molding machines, in the way, it significantly shortens the cycle time and increases the production efficiency.
4. Adopt the speical designed screw and injection unit, in order to facilitate PET raw materials plasticizing and molding.
5. The ejector system can be well meet the production of PET products.
6. With the high-power motor pump system, it can achieve shorter cycle time.
7. With the high g torque hydraulic motor for plasticizing, it can charging and mix the pet material well.
8. Bigger tie bar distance, compare with other supplier, we have bigger tie bar distance, we can put big molds in the machine.
9. Long openging stroke, compare with other suppliers, we have long opening stroke which can produce deep cavitiy product install competitor bigger size of machine.

Industry Knowledge Expansion

A PET (Polyethylene Terephthalate) injection molding machine is a type of plastic injection molding machine specifically designed to produce PET preform and bottle products. PET is a thermoplastic polymer material that is commonly used to make containers, such as bottles and jars, for food, beverage, and other consumer goods.

PET injection molding machines work by first heating the PET resin into a molten state and then injecting it into a mold, where it cools and solidifies into the desired shape. The molding machine typically features a high-pressure injection system, which is necessary to ensure consistent and accurate filling of the mold, as well as an efficient cooling system to rapidly cool the molten PET.

PET injection molding machines are typically designed to meet the demands of high-volume production, offering fast cycle times, high precision, and efficient production capabilities. Additionally, the use of PET resin provides several benefits, such as high strength, transparency, and resistance to impact and heat, which make it an ideal material for a wide range of applications.

PET preform injection molding machines are specialized machines used to produce PET preforms, which are plastic containers that hold liquid or semi-liquid substances. Some of the key features of PET preform injection molding machines include:

High precision: They are designed to produce high-precision, uniform PET preforms with consistent wall thickness, weight, and dimensional accuracy.

Fast cycle times: PET preform injection molding machines have fast cycle times, allowing for increased productivity and efficiency.

Efficient production: They are equipped with advanced control systems and efficient hydraulic systems, making them ideal for high-volume production.

User-friendly operation: PET preform injection molding machines feature an intuitive HMI, making it easy for operators to set up and monitor the molding process.

Customizable: They can be configured to meet specific requirements, such as the production of different sizes and shapes of preforms, and the use of different materials, such as recycled PET.

Energy-efficient: They are designed with energy-saving technologies, such as servo motor drives, to reduce energy consumption.

Low maintenance: PET preform injection molding machines have fewer components compared to hydraulic machines and use modern, reliable electric servo drives, reducing maintenance requirements.
