Detailed Product Description


EA series 2-component elastomer casting machine, dosing machine, mixing machine

1. Summary:

Our pu casting injeciton machine is that our company follows the international advanced technological products, imports the main machine parts from foreign countries and famous brands. Hence, technical and safety performance of the equipment has reached the advanced level of the same product of the same period abroad.

This machine is used for producing casting polyurethane elastomer product which use MOCA and other material as chain extender, such as gluing roller, pad, rollers for elevator use and highly rigid products and can compose pre-polymer and vacuum defoaming in this machine.

Different PU rubbers can be switched instantaneously to produce CPU of different materials.

Heating: Independent electrical heating Mixing by mixed-head match with the motor

Temperature check: Thermal sensor.

Tolerance on the temperature maintenance: +/- 1°C

Motor: Electric motors, controlled by a frequency convertor.

Our uniquely mixing head design has the following features: It can guarantee the accuracy of speed, and at a very low speed of the mixed quality of raw materials; so that the prepolymer does not cause pressure damage to properties.

Made of special alloy mechanical seal system made the mixing head also could work in the high anti-pressure, while ensuring the reliability of mixed system.

Unique design of the mixing chamber can be cleaned to ensure easy-to-use and thoroughness.
