Now day’s manufacturers are turning to overmolding plastic part as they are learning how it adds value to their product lines. It also lowers total production costs-a rare combination apart from just improve functionality and performance and aesthetics.
It is a one-shot or two-shot process that to the substrate of the product bonds a thin layer of TPE (thermoplastic elastomer). For a wide range of products, ranging from personal care products like toothbrushes to power tools this exterior layer is what creates the soft-touch grip that is quite popular. Over molding can be a barrier to oxygen and moisture and also reduces provides electrical insulation, shock, and vibration and dampens sound, boosts chemical/UV resistance.
As a result, this kind of feel is demanded by the consumers to the products they purchase and thus overmolding applications continue to expand. Product engineers get more options for creating attractive and functional products and staying on the leading design edge of their markets b the availability of this technology.
Not every overmolding plastic part china can over mold; however throughout the production run it requires extensive training, specialized equipment, and precise control of multiple variables. Quality gets affected by even the slightest variations, so it is a must to have skilled operators. The maximum of this knowledge is related to the type of TPE and substrate being used, so it is very much important to have a deep understanding of material science and chemical behavior.
Vents must be properly sized for tooling and during over-molding, they are placed in the mold to permit the release of air from the mold cavity; between the TPE and the substrate trapped air can weaken the bond. For the materials involved to eliminate the risk of delamination or curling the shutoff must also be properly designed.
It’s quite rarely found when an advanced technology improves product viability and customer satisfaction and still reducing overall production costs. As over-molding by overmolding plastic part Manufacturer reduces the number of steps involved in making the product as a result the total costs get automatically lower. Into one injection molding process by combining these steps, over-molding increases boost throughput, quality, reduces waste, and decreases overall production cost.
