Micro Foam Injection Molding Process
Feb 20, 2023
It is an innovative precision injection molding technology, which uses the expansion of pores to fill the product, and completes the molding of the product under low and average pressure.
Fundamental:
The microcellular foam molding process can be divided into three stages: first, the supercritical fluid (carbon dioxide or nitrogen) is dissolved into the hot melt adhesive to form a single-phase solution; Cavities, due to the instability of molecules caused by the decrease of temperature and pressure, a large number of bubble nuclei are formed in the product, and these bubble nuclei gradually grow to form tiny holes.
