Our Solution 


Since the product required high volume production, we created a fully automated process for the part using a transaxial robot to load the two brass inserts into the injection mold. The inserts were preheated before inserting into the mold to achieve a perfect match with the elevated mold temperatures. The preheating process minimized warpage and unwanted stresses which can occur in the plastic part if a cold insert was overmolded. The insert molding process produces a robust thread feature within a plastic part without the need for unscrewing mechanisms.


Application Of Insert Molding 


Metal, ceramic or plastic pieces can be inserted into the molten thermoplastic to form multi-material, robust parts with additional functionality. For example, threaded metal inserts can be molded into the parts to allow them to be attached to other parts.


Insert molding can reduce cost by embedding secondary parts into the plastic injection molding process, as opposed to installing the parts after molding. By integrating the inserts at the time of molding, the parts become more robust compared to staking the pieces in post-molding. Of course, the insert pieces must be able to withstand the high temperature and pressure of the injection molding process.


Insert molding is naturally a more complex process that standard injection molding, so some injection molding companies are more experienced in the process than others. For low-volume production runs, a machine operator may load the inserts into the mold by hand, prior to the plastic injection cycle. For high-volume production runs, however, it is common to use automated machinery to place the inserts into the mold.
