The overmolding begins with development of a two-cavity, or space in the tool. In one area the company fills the hard plastic, and in the other space they apply (pour?) The soft rubber. Afterward, the plastic cools off and solidifies, at which point the tool rotates and the rubber is injected into his second space. It is this unique process that allows both materials to bond together so well, making them strong and durable products which are made dependable for everyday use.
Consider a phone case designed with overmolding. They involve a rugged outer shell for impact protection with an inner core (such as soft rubber) that allows you to grip the phone better. It is true that Rega (yixing) has created a product, which allows for the same rapid technological output in spite of your hands becoming wet or sweaty as would often be the case with most people.
It's Only The Beginning: Overmolding has really opened up the floodgates of manufacturing and products that are used every day. Historically, that means a company used to have to make individual pieces, then put them together to create the end product. It used to be a long process that increased cost of production. Despite that, with the advent of overmolding, this has permitted one homogeneous piece to suffice and outperform the former technology. This has made it easier for businesses to manufacture better products with fewer defects and less waste.
Safety features are one domain in which the automotive segment has reaped significant rewards through overmolding. For example, you can develop airbags via overmolding with the sensors directly in the steering wheel without a requirement of producing and adding extra components. What that means, in a nutshell, is better cars and easier design.
Companies must consider some crucial factors to determine if overmolding is the right method for producing their parts or products. The first issue to consider is what materials are needed for the product. Over molding is more useful when it comes to the parts which need to be strong as well as soft like handles, grips and phone cases. It also creates more texture in products, which makes them easier and more pleasant to use.
It is also necessary to take into account the durability of existing materials and tools for production. Although there may be a higher initial cost for building the tool for overmolding as opposed to standard methods, in many cases this long-term consideration mitigates or even surpasses that up-front cost, because the part is likely expected to perform and look better now and down the line.
There are several considerations that companies need to make when designing products for overmolding. To begin with, they have to be certain that the two materials will stick well together. After all, it sits at the core of creating a high-quality end product. Secondly, they have to create a device which is going to put the two materials in place and where we press on the final dress we have on the out side. Third, you need to know where injection points for materials will be needed If these points are not taken care of properly, they may deteriorate the look and performance of the end product.
