Design and production of foaming molds: Foaming product foam mold factories should be designed reasonably. The requirement for the mold is that the heating should be even and the cooling should be even. The air hole is selected in a place with a large space. During production, the foamable resin is directly filled into the mold, and it is heated and melted to form a saturated solution of air foam mold liquid. Through nucleation, a large number of tiny bubble nuclei are formed, and the nuclei grow to form foam plastic parts. There are three commonly used foaming methods: physical foaming, chemical foaming and mechanical foaming.
