    Insert Injection Molding Service

    Insert Molding is the process of securing the insert at proper location in the injection molding, then molding it with plastic. The molding is then wrapped in cooled and solidified plastic and buried tightly inside the plastic to produce a product with inserts, such as threads and electrodes. Plastic inlaid with metal, glass, wood, fiber, paper, rubber or formed plastic parts are called inserts, the most common inserts for metal.

    Where the injection part is required to include other parts that have already been machined, the use of inserts in the mold is the most reliable form, as this way the pre-machined part for fixation is completely wrapped in plastic. Usually we see the connection plug containing copper core, wrapped in plastic iron chip and so on are in this form. In the die casting mold, there is also the use of this form, such as the car driving wheel parts. When we require injection parts to contain two kinds of performance or color different materials to achieve special appearance or use requirements, we will also use the method of forming one of the materials first, and then put it into the injection mold of another material together. In fact, two-color or multi-color injection molding is basically the application of this principle. The first part of it is called a plastic insert.

Here two color pistol grip, utilizes TPU injected onto PC material.Two types material should form a bond and offer functional performance. Compared with the third-party material bonding, over mold process makes the process faster and more cost-effective, it has been widely employed in plastic design.

    Regarding over molding mold design,we must take shrinkage into consideration due to two different plastic materials.Two material both have their own injection gate and runner systems. And the wall thickness of over mold should be as uniform as possible in order to have the shortest cycle time. In the range from 0.7mm to 2mm will ensure very good bonding of two materials in most over molded applications. But if final part requires the use of thick, then they should be cored out to manimize shrinkage problem and to reduce the part weight and cycle time.
