Injection Speed Med
These process conditions may vary with individual equipment and processes.
• Secondary Processing
As a thermoplastic material, Si-TPV® material can be secondary processed for ordinary products
• Injection Molding Pressure
The holding pressure largely depends on the geometry, thickness and gate location of the product. The holding pressure should be set to a low value at first, and then slowly increase until no related defects are seen in the injection molded product. Due to the elastic properties of the material, excessive holding pressure may cause serious deformation of the gate part of the product.
• Back pressure
It is recommended that the back pressure when the screw is retracted should be 0.7-1.4Mpa, which will not only ensure the uniformity of melt melting, but also ensure that the material is not severely degraded by shear. The recommended screw speed of Si-TPV® is 100-150rpm to ensure the complete melting and plasticization of the material without material degradation caused by shear heating.
