[0002] Moulds are tools used to manufacture various products in industrial production. They are produced by injection moulding, blow moulding, extrusion, die casting, forging, smelting or stamping to obtain the desired products.

[0003] When producing car seats, molds are needed for foaming production. The mold for foaming molding is a plastic foaming mold. The foaming resin is directly filled into the mold, which is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed. The bubble nuclei grow to make foam plastic parts. There are three commonly used foaming methods: physical foaming, chemical foaming and mechanical foaming.
