Rub the resin sticks and glass fiber adequately, then receives the volume, carries on essential curing processing. When the sheet material does not interfere, we can to cut out certain size as the request, take off the both sides membrane, and then fold in the metal mold to heat up and pressure forming the certain product.
According the product structure, the request as well as mold's situation to chose the SMC series and the way of formation such as the mold pressing law, transmission mold, and injection mold.
When pressing formation, put the weighed SMC mold plastic group into the preheated mold, close the molds quickly and accord the following condition to suppression formation.
a. Pressure: Generally in 60-80Kg/㎝2
b. Temperature: Formation temperature generally in 140-160℃, cover mold compared to after mold temperature high 2-5℃
c. The time of heat preservation and guarantees pressure: Generally in the 40-60s/mm thickness, different according to the products’ thickness.
