•  Guidelines on Insert Molding

    What is Insert Molding? Insert molding is a process of fabricating a finished part by applying a metal part into  moltenres in a mold. As compared to installing inserts into a plastic molded part in a post-molding process, the use of molded-in inserts eliminates the need for secondary installation of the inserts and thereby reduces costs. The mold temperature of INSERT MOLDING process is 65 -120 cels degree, and the material temperature is 260-320 cels degrees. Of course, different raw material ratios have different temperature ranges requirment and the resin producer will provide upper and lower limit temperature with the datasheet.   The upper limit temperature indicates the temperature at which the material begins to carbonize and decompose, while the lower limit temperature indicates the temperature at which the material begins to flow.On one hand, if the molten temperature is lower than the lower limit, the liquidity of the material is insufficient, and the insufficient plasticity of the molding screw can easily break the molding…
