Points to note about PPS injection molding parts

Due to PPS being a crystalline resin, stress concentration will occur in the corners and wall thickness changes of the product. Cracking, dimensional changes, and decreased impact strength are prone to occur in these areas. Therefore, when designing PPS injection molding parts, attention should be paid to adding radius to the corners of the product and trying to make the wall thickness as uniform as possible. Adding reinforcement ribs in appropriate positions can increase the strength and rigidity of the product, eliminate residual stress, and improve fluidity.

Although PPS has a low water absorption rate (about 0.03%), in order to reduce nozzle leakage, silver wire and bubbles, PPS injection molding material should be dried thoroughly. A dehumidification dryer should be selected, with a drying temperature of 160 ℃ and drying for 3-4 hours.

The injection pressure and injection speed have a significant impact on the fluidity of the melt and play an important role in the quality of the mold and the PPS injection molding product. The injection pressure is generally 80-130 MPa. The faster the injection speed, the better the surface smoothness of the product, but it is prone to product warping and burning. It is important to note that a moderate injection speed is generally used. More information please check Yuanfang plastic injection mold making process for reference.
