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 rubber mold cavity undergoes vacuuming, heating, and compression, which cause the rubber compounds inside the custom mold begin to vulcanize, then fully compression molding 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.
