The basic molding requirement calls for a mold that will compress the plastic into the desired shape and hold it under pressure and heat until the molding cycle has been completed. The operation must be done in the simplest manner and for the least cost, which requires that the mold be designed so that the resin and insert could be introduced easily and the part ejected. A good source to study the procedure for designing compression molds is Plastics Mold Engineering HandbookS ...

PPS resins are chiefly used for injection molding. The melt flow of the glass-filled resins is very stiff, and high injection pressures are required. Mold surface wear is heavier than for most other engineering plastics. Molding melt temperatures are near 330°C for optimum surface gloss and impact strength, mold temperatures of 130°C should be used. The resins are brown to brown-black.
