Why Use Insert Plastic Molding?

Insert plastic molding, or overmolding, involves placing insert parts (usually made from metal or other suitable materials) into a mold before injecting plastic into the mold cavity. The plastic resin hardens around the inserts, creating a single product. This process was initially developed to place threaded inserts for plastic molding into molded parts.

Insert plastic molding has helped improve several part manufacturers’ product quality, as well as improving order turnaround time. Rather than purchasing the costly equipment and training employees to produce plastic molds and operate the plastic molding machines, most manufacturers instead hire out this work to specialized plastic molding companies.

Contracting with a professional insert plastic molding company like Streamline Plastics produces many benefits, including:

  1. Lowers labor and assembly costs. Complex projects can be turned over to turnkey operations with streamlined processes and the latest equipment, allowing for dramatically reduced labor and assembly costs but resulting in a higher-quality product.
  2. Design flexibility. Plastic insert molding opens up a world of possibilities for designers, allowing for parts that move freely.
  3. Smaller, lighter products. Using plastic inserts instead of fasteners and connectors leads to products that are both smaller and lighter weight.
  4. Increased reliability of products. Components encased in tight, secure plastic will experience less misalignment or other defects.
