What is Compression molding? Compression molding is that uncured rubber compounds, preformed into shapes like disks or strips, are precisely placed into the core of a custom rubber mold installed on a vacuum vulcanizing machine. As the machine operates, the mold cavity undergoes vacuuming, heating, and compression, which cause the rubber compounds inside the custom mold to begin to vulcanize, then fully cured and transformed into the final molded silicone products through the application of controlled heat and pressure. The curing time from 60 to 250 seconds is different depending on the product structure, vulcanizing machine tonnage, and specific rubber compounds used.
Compression Molding Process
