Process time compression molding bakelite

WebbAfter the mold is closed and heated, the punch compression (hence the name of this molding technique) eases the flow of the material so that under the compression pressure it acquires the expected mold shape and the molecular crosslinking process gets started. When heating cycle time is up, the mold is opened and the molded product removed. WebbThermoset compression molding At Van Norman, we’ve optimized the thermoset molding process. In order to reduce costs, shorten cycle times, increase part consistency and improve structural integrity, we carefully design molds and mold builds. In addition, we use state-of-the-art molding techniques, such as in-mold pressure and temperature sensing.
