Overmolding Services In China
What Is Overmolding And How Does It Work?
Overmolding is a specialized type of injection molding technique. It consists of creating an injection-molded part and then using another injection mold to add additional layers to the current part.
Essentially, overmolding is the process of combining two different plastics into a single part by molding one material over the other – which is where the term “overmolding” comes from.
What Are The Benefits Of Overmolding?
Saves time and money
First and foremost, overmolding from Qmolding lets you save both time and money. We can create overmolded parts in a quick, two-step process using our injection molding machines – so there’s no need to outsource this process.
No need for additional adhesive
Add different textures, designs to parts
For these reasons – and many more – overmolding from Qmolding is a very useful, versatile method of creating plastic components, parts and products.
What Material Combinations Are Appropriate For Overmolding?
However, you must take care and make sure that your combination of materials is compatible with overmolding, by ensuring the following:
Initial part is made of heat-resistant material
The part that is created first must be made of heat-resistant plastic. Otherwise, it may melt when exposed to the high temperatures of injection molding the second material.
The two plastics don’t react
The two plastic resins used must be non-reactive, otherwise, the overmold will completely fall apart and fail.
You work with an experienced overmolding company
Overmolding is more complex than simply injection molding. It takes proper technique, the right equipment, and a good understanding of the plastic resins that are commonly used in manufacturing today.
What’s The Difference Between Overmolding & Insert Molding?
Insert molding and overmolding may look similar on the surface, but these processes are a bit different.
Insert molding, in contrast, is the process of loading a preformed part (usually metal) into a mold, where it is molded with a special thermoplastic resin to create the final component. For example, brass contacts may be embedded in a plastic resin to create a plastic electrical connector, or a metal threaded insert may be placed into a plastic housing.
