Cause of Injection machine screw break

1. The screw itself is of poor quality.

2. The temperature of the barrel is set low, and the shearing force of the screw rotation is too large.

3. The length-to-diameter ratio of the screw is not suitable and is large.

4. There is a problem with the screw installation

5. There are too hard metal or non-metallic impurities in the raw materials used.

6. The injection molding machine is cold-started, and the viscosity of the raw material in the barrel is too high.


Requirements For Screw Performance On Material Properties

 1) wear resistance and long life;

 2) High temperature resistance, no deformation under high temperature;

 3) Corrosion resistant, the material is corrosive;

 4) Has good cutting performance;

 5) High strength, can withstand high torque, high speed;

 6) The residual stress is small after heat treatment, and the thermal deformation is small.
