Microcellular Foaming Injection Molding

Microcellular foaming injection molding is a plastic processing technique that enhances the production of plastic parts by introducing gas (N2 or CO2) into the melted plastic material. By pressurizing the gas to a supercritical state, it is mixed with the molten plastic to form a single-phase solution. During the injection process, a rapid drop in pressure causes the gas to form uniform microbubbles within the plastic, resulting in a product with a honeycomb-like internal structure.
