There are various types of plastic injection molding materials, and a wide variety can be selected depending on the application. If the moldability is not good, the molded product will not be formed, the precision will be poor, the mold releaseability will be reduced and the molding cycle will be prolonged, so the yield will be reduced and the cost will be increased.
Good moldability has the following eight points.

① Wide range of temperature and pressure for injection molding, suitable values　
② No change in physical properties and appearance even when left at molding temperature for a long time
③ The fluidity of resin is suitable for injection molding
④ Short molding cycle
⑤ Easy to release
⑥ Low molding shrinkage
⑦ No special precautions required for pre-drying
⑧ Easy to color
