What You Need to Know about Large-part Injection Molding

Plastic overmolding uses multiple materials to create a single component. It is a two-step procedure requiring a substrate material at the start. It molds the initial molten plastic over another molded part. It also utilizes a specialized machine that can make the cycle more convenient.

If you are thinking of making an item with this process, we at Richfields Corporation can help you. Our advanced techniques ensure the precision of your product’s specific needs. With years of experience in plastic manufacturing, our techniques for plastic overmolding in China will seamlessly integrate your design into your ideal plastic item.

Materials Used in Plastic Overmolding


Various plastic materials are pivotal in this process. They are the foundation to make complex and high-quality products a reality. Each has its unique qualities and advantages that manufacturers take into consideration. Some materials used in plastic overmolding in China are the following:

  • PEI (Polyetherimide)
  • Acrylonitrile butadiene styrene (ABS)
  • Polyetheretherketone (PEEK)
  • Polymethyl methacrylate (PMMA)
  • High-density polyethylene (HDPE)
  • Low-Density Polyethylene (LDPE)
  • Polypropylene (PP)
  • Thermoplastic Elastomers (TPE)
  • Polyoxymethylene (POM)
  • Polyetherimide (PEI)

Since the technique molds together various materials, the types of plastic should be compatible. This allows for a better combination process to make the ideal item. The guidance of an expert plastic manufacturer is a significant help. They ensure that the materials are chemically and thermally compatible to suit your requirements.

Types of Plastic Overmolding Processes


There are two processes in plastic overmolding in China. Each has its distinct benefits that can make manufacturing your product more convenient. These injection molding methods focus on how substrate-molded products are made.

Insert Molding

Insert Molding

The main requirement in insert molding is utilizing a pre-molded performed insert. It is usually made of a metal material like brass. This pre-made component is placed into a mold and a second material is shot to cover the first part. This type of plastic overmolding in China uses a conventional single-shot insert molding machine.

Multiple Material Plastic Overmolding

Multiple Material Plastic Overmolding

This process requires unique injection molding equipment designed with several barrels. The number of barrels usually pertains to the quantity of materials you can use. It is an efficient and cost-effective method since the molding process of the materials is all done in the same cycle. This reduces the time to produce a plastic component.

Common Applications of Plastic Overmolding in China


Overmolding can accommodate a wide selection of materials in a variety of combinations and formats. It can be used for nearly every application you can think of. With the right designs, materials, and processes, the technique enhances the functionality, aesthetics, and durability of plastic components.

From rubber grips to waterproof seals, this plastic manufacturing method is a cost-effective and quick process that can create many kinds of products with reliable quality. Whether it is industrial or construction applications, it offers an efficient solution to meet the demands across different industries.
