Polystyrene Forming

Amorphous materials, moisture is small, not be fully dry, is not easy to decompose, but large coefficient of thermal expansion, easy to produce internal stress. Good fluidity, available screw or piston type injection molding. Suitable for high temperature, Gao Mowen, low injection pressure, within the extended time helps to reduce stress and prevent shrinkage and deformation ... Available forms of gate, Gate connected to the arc for plastic parts, so as not to damage plastic parts of the gate. Stripping slope, and out of uniform. Plastic parts uniform wall thickness, preferably without inserts, such as insert should be preheated.

1. water absorption very small, not before drying. Mold temperature 30-60 degrees, the temperature of 140-200 degrees.

2. the brittle crack, thermal expansion coefficient, is easy to produce internal stress.

3. better mobility, should pay attention to the die clearance to prevent shrinkage and Flash.

4. suitable for high temperature, Gao Mowen, low injection pressure, within the extended time to reduce stress to prevent shrinkage and deformation, temperature is too high, vulnerable to silver, or release agent a much lower temperature then the poor transparency.

5. can take a variety of forms of gate, stripping slope should be large, ejection force evenly to prevent cracking.

6. plastic parts uniform wall thickness, preferably without inserts, the surface should be circular connection, not chipped, sharp corners.
