Plastic Injection Molds

With our experience and advanced machinery, we specialize in designing and manufacturing a range of injection moulds to adjust your tolerances and costs.

Plastic Injection Molding

Plastic Injection Molding

Our plastic injection molding process uses precise machinery to shoot molten resin into a mold to become a final production-grade thermoplastic part.

Overmolding

Overmolding

Covering plastic, metal, and rubber over each other via chemical bonding, our overmolding reduces assembly time and gives our parts greater strength and flexibility.

Overmolding

Overmolding

Insert molding is the process of molding thermoplastic material around a preformed component to create a finished part that incorporates multiple materials.

Injection Molding Materials

When selecting the materials for the injection molding process, there are a ton of options including thermoplastics, thermosets, metals, and elastomers. At Junying, a wide selection of more than 100 thermoplastics and polymers are available, we’ll help you choose the optimal material based on the part and application.
