Thermoset Molding

Thermosetting plastic molds are mainly used for molding thermosetting plastic products, that is, powder thermosetting plastics are processed and formed. There are three types of thermosetting plastic compression molds, thermosetting material transfer molds, and thermosetting plastic injection molds. Commonly used thermosetting plastics are phenolic plastics (ie bakelite), amino polyesters, epoxy resins, poly diallyl phthalate (PDAP), silicone plastics, etc. We provide professional manufacturing services for FRP molds, composite molds, SMC/BMC molds, compression molds, and thermosetting molds.

Important Considerations for Thermosetting Plastics in Injection Molding

The molding temperature must be strictly controlled (when the temperature is low, the plasticization of the material is insufficient, and the fluidity is poor, and if the temperature is slightly higher, the fluidity will become smaller or even hardened), usually a water heating system controlled by a constant temperature is used, and the temperature can be accurate. The ground is controlled within the range of ±1°C.

When the thermosetting plastic undergoes cross-linking reaction in the mold, low molecular substances are precipitated, so the mold clamping part of the injection machine should meet the requirements of the deflation operation.

The thermosetting plastics should not stay in the barrel for too long to prevent hardening. Usually, multi-mode replacement is used.

The injection pressure and clamping force of the injection machine should be larger than that of the injection machine for molding thermoplastics.

Benefits Of Thermoset Plastic Molding

Thermoset materials have good insulating properties and are resistant to electricity and heat, making them ideal for the electrical, electronic, and appliance industries.

Thermoset-molded plastic resists corrosion and retains its mechanical properties at elevated temperatures, increasing its durability and reducing the risk of shrinkage over time.

Manufacturers can maintain tighter tolerances in thermoset moulding process than thermoplastics.

Thermoset Injection materials have high impact strengths.
