Surface Finishes for Injection Molding

XinCheng offers a comprehensive list of secondary finishing operations to improve the mechanical and aesthetic appearance of your product. We will work with you to choose the suitable finishing option for your part’s application.

Glossy (A)This finish is made of diamond buffing and produces glossy and shiny surfaces on injection molded parts.
Semi-glossy (B)This is a B-grade surface finish with a slightly rougher finish due to the use of grit sandpaper. Custom-molded plastic parts with this finish will have matte textures.
Matte (C) A C-grade finish that produces rough and uneven surfaces with grit sanding stones. They also have matte surface textures.
Textured (D) D-grade finishes use dry glass beads and grits to create a rough textured surface. Products can have a satin or dull finish depending on the material used.

Advantages of Injection Molding

  • Efficiency and Quality
    After mold development, the injection molding process can operate at a remarkable speed, with fast cycle times. It is particularly beneficial for medium to high-volume production runs.
  • Large Material Choice
    Injection molding is compatible with a lot of materials, and they’re customizable. You can choose materials flexibly depending on the specific applications of your final part.
  • Excellent Surface Finish
    Injection mold tooling is carefully CNC milled and finished, giving the parts an excellent surface. Typically, the parts produced require little post-processing.
  • Scalability and Repeatability
    Injection molding is the cost-effective method for specialized manufacturing runs of 500 to more than 500,000 parts. It ensures the repeated production of identical products.

Injection Molding FAQs

Injection molding is a plastic production technique where plastic polymers are melted to create desired components. The molten plastic resins are solidified under pressure in mold tooling that has been pre-machined in the shape of the desired part. Custom injection molding can create thousands of parts with the same shapes and complexities.

We create injection mold tooling with production-grade steel or aluminum materials using CNC machining to ensure high accuracy and precision. Therefore, it is typically possible to achieve tolerances of up to +/- 0.005 inches for injection molded parts. Some machines can even achieve more restrictive tolerances.

You will get injection molding quotes after our platform has considered several variables, such as the component’s size, the complexity of the mold, the number of injection cavities, the materials, the requirements for post-processing, etc.

Injection molding is a highly versatile manufacturing process used in various industries. These include the aerospace, medical, electronics, and energy industries. Injection molding also helps produce consumer goods, including housewares, kitchen appliances, and cosmetic packaging. Toys and game manufacturers rely on injection molding to produce intricate, complex, customizable parts.

It takes approximately 35 days to design and create the mold and another three to five days to produce the molded parts after you make your order.

Yes, we offer production tooling for the on-demand manufacturing of custom plastic parts. This tooling option ensures multi-cavity capabilities, longer production runs, and a cost-effective molding process.
