Our Injection Molding Capabilities
From plastic protot🃏yping to production mo🎃lding, cncjsd custom injection molding service is ideal for the manufacturing of competitive pricing, high-quality molded parts in a fast lead time. Strong manufacturing facilities with powerful, precise machines ensure the same mold tool for creating consistent parts. Better yet, we provide free expert consultation on each injection molding order, including mold design advice, materials&surface finishes selection for your end-use applications, and shipping methods.
Plastic Injection Molds
With our experience and advanced machinery, we excel at designing and manufacturing a series of plastic injection molds adjusted to your tolerance and cost.
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
Covering plastic, metal, and rubber over each other via chemical bonding, our overmolding reduces assembly time and gives our parts greater strength and flexibility.
Insert Molding
Insert molding is the process of molding thermoplastic material around a preformed component to create a finished part that incorporates multiple materials.

Surface Finishes of Injection Molding
Injection molding includes injection mold tooling, plastic injection molding, and more. The surface treatment of the mold is usually completed during the production process. After the injection molding is completed, we will carry out certain surface treatments on the finished product as per your requirement.
| Name | Description | Link |
 | A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts. | - | |
 | Semi-glossy | B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture. | - |
 | Matte | C grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture. | - |
 | Textured | D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish. | - |
