All about Overmolding
More manufacturers are swinging to overmolding as they figure out how it increases the value of their product lines. It does not just improve the usefulness and style of the items, it also lessens the expenses of the generation which seldom occurs. Overmolding can be done either in one-shot or two-shot that connects a very thin layer of thermoplastic elastomer to the substrate of the product. The external layer is soft, and this makes the items a most loved of the population, regardless of whether they are purchasing a toothbrush or a power device. Overmolding also diminishes shock and vibration, dampens sound, gives electrical insulation, supports chemical/UV resistance, and can be a barrier to oxygen and moisture. Since it began, customers expressed a liking for products that have gone through that process, and more companies have started using it. Also, producers have an assortment of styles to browse, and overmolding empowers them to be at the front of the competition.
For an injection molder to overmold, there as to be a lot of preparation put into it; the hardware used should be specialized and the factors used should be monitored. This is important because just a slight variation can greatly affect the outcome; therefore, the operators working on it should be very skilled. The factors that are used depends on the substrate that is being worked on; therefore, the people operating on it should have all the knowledge required for that. The materials utilized in the process continue developing, and greater usefulness is being added to them. A key advance in overmolding is deciding the best TPE/substrate mix for optimal bonding, trailed by structuring the suitable mold and tools. Maintaining the melt temperature of the TPE is critical. It is very important to keep the surface of the substrate free of all blemishes. Any contamination superficially could incredibly influence the bond between the two things as it could be frail or could even fail. Also, any moisture that is on the surfaces can influence the bond so they should be dried very well before molding.
When the process is ongoing, vents of the right sized should be used to release the excess air from the mold, and this is because if any remains, the bond will be weak. The shutoff should also be properly designed for the materials required to wipe out the risk of delamination or curling. It’s uncommon when a cutting edge innovation improves product viability and consumer satisfaction, yet still reduces overall production costs. Total costs are lower because overmolding can reduce the number of steps involved in making the item. One good example is how the bond formed is so strong that there is no need to do things like painting or coating. Overmolding goes a long way in reducing waste and increasing the quality of products.
