Materials for Injection Molding
These are common molded plastics offered by our injection molding services. After knowing the basics of materials such as common grades, brands, advantages, and disadvantages, choose the appropriate injection molding material according to your application requirements.
Tooling Materal
Before injection molding process starts low or high-volume production, a high tolerance CNC machined tooling is needed. Most commonly used materials include:
| Tool Steel: | P20, H13, S7, NAK80, S136, S136H, 718, 718H, 738 |
| Stainless Steel: | 420, NAK80, S136, 316L, 316, 301, 303, 304 |
| Aluminum: | 6061, 5052, 7075 |
Plastic Materials
Plastic injection molding service comes with a wide range of materials with different properties, including impact strength, rigidity, thermal resistance, chemical resistance, etc.
| ABS | Nylon (PA) | PC | PVC |
| PU | PMMA | PP | PEEK |
| PE | HDPE | PS | POM |
Additives and Fibers
Standard plastic materials may not meet custom injection molding parts requirement. In this case, additives and fibers can be added to improve aesthetic and functional properties, providing additional features for your injection molded parts.
| UV | absorbers | Colorants |
| Flame | retardants | Glass fibers |
| Plasticizers |
Surface Finishes for 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.
Glossy
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.

I worked with another Chinese injection molding factory for eight years, and while the relationship was initially great, eventually became disappointed by quality issues, late delivery, and a complete lack of communication. Decided to give NOBLE a chance with a small order. Not only did they deliver on schedule, but they also did itwith100% accuracy and attention to detail. It was the same with my next order.
What is Injection Molding?
Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, and easy replacement of products, and complex conditions. In parts, injection molding is suitable for mass production, complex shape products, and other molding processing fields.
