Today, turning to overmolding is being done by many manufacturers. Overmolding is essential to them because it helps them add value to their product line. the functionality, performance, and even aesthetics are improved when overmolding is done. More to that, the total production costs of their products are lowered by overmolding these days. Overmolding involves two processes and they are one-shot and two-shot processes. What is overmolding? It is a thin layer of thermoplastic elastomer is bonded to the substrate of products through a process.
An exterior layer is created when overmolding is done on products. The exterior layer is the one that produces the soft touch grip that is found with many products. Overmolding can be done to several products such as toothbrushes and even modems. Apart from improving the quality of products, other benefits that overmolding process offer to them are many. Some of these benefits are like shock and vibration reduction, dampens sound, provision of electrical insulation, increased chemical resistance and also acts as a barrier to oxygen and moisture.
2 shot overmolding is a process where one material is injection molded over the previous injection molded substrate. 2 shot overmolding is mostly done on electronics such as modems. Overmolding of these electronics is done with a more durable engineering thermoplastic. Electronics become chemical resistance, bio-compatibility and also superior abrasion when overmolding process is applied. When 2 shot overmolding is applied on products, it combines the benefits of low pressure molding with conventional injection molding. Low pressure is the one will be started with when this process is being used to form a premolded device.
Safely encapsulated is one of the benefits that is enjoyed when products are premolded. You can then use a high pressure injection process after that process. This process will seal and protect the electronics with a rugged thermoplastic outer layer. Many benefits are offered to products especially the electronics when 2 shot overmolding is applied. Other stuff such as solvent resistance and biocompatible overmolding materials rated by FDA are required by many medical and consumer electronics appliances. A lot of manufacturers of such electronics apply a 2 shot approach on such products.
Protection is provided by the overmolding process to electronics. Finishing of overmold is done with materials that customers’ needs. Manufacturers are helped to confirm their gating location by the first low pressure molding shot which is why it is important. Trapped air and unsightly flow fronts are some of the things that are prevented by low pressure molding which makes it to be important. Electronics such as batteries are enjoys improved heat and pressure distribution when the first low pressure molding shot is applied. Click here for further details.
