Insert Molding is when plastic is injected into the mold cavity and insert piece (or pieces) prior to plastic injection molding. The resulting product is a single piece with the insert encapsulated by the plastic.Insert Molding Benefits:Faster Assembly TimeReduced Part SizeReduced Part WeightCost-EffectiveInsert Molding Product Examples:Filters with Fine Mesh InsertsVacuum Hose ConnectorsAutomobile Air DuctsHeavy Equipment ComponentsMedical Syringes*Special Notes: When it comes to plastic injection molding, temperature plays a vital role in part quality. The most common temperature-induced defects are Warpage, Sink Marks and Jetting. In plastic injection molding, if gate size is inadequate the flow rate of the molten resin will be restricted as it tries to move through. This restriction can cause the filling rate to slow down enough to cause an excessive pressure drop from point-of-gate to last-point-to-fill. Gate size will depend on the resin being used and the size of the part being molded.*The larger the gate, the better and easier it is to make high quality parts.*

How Are Injection Molds Made

With today’s machinery, plastic molders are able to inject resin very fast, very slow, or variations of both throughout the process, but within the same injection phase. PMC is one of the few plastic injection molding companies who has in-house Master Molders (there are less than 1,000 Master Molders in the entire world). Many plastic mold design projects have landed with us because others were not able to manufacture a product the way the customer had intended.

Good communication with your new molder is imperative to satisfying results. Continuous interaction with your new partner and creating a solid foundation of your business relationship will only benefit the development process.Quality versus Quantity: Is cost the important aspect of your project?? Quality stands the test of time; it may not be obvious until parts fail to do their job in the finished product. You supply your customers with reliable products. Be sure your molding company is supplying you with a dependable process.

How To Store Resin For Injection Molding

Since the nozzle is the final transfer point from the barrel to the mold, it’s essential to analyze. If the nozzle is too cold, the resin’s travel time can slow which prevents the molecules from getting properly packed. If the molecules don’t pack evenly, they will shrink at different rates which causes mold warping. Operating environments is a key component in plastic injection mold design.
