Tooling Materials

Before starting injection molding for low or high-volume production, high-tolerance CNC machined tooling is requisite. the materials used for CNC tooling are:

Tool Steel:  Stainless Steel: P20, H13, S7, 718, 718H, 738, NAK80, S136, S136H,420,S7,1.2311,1.2312,1.2344,1.2343,1.2767 ,1.2085,1.1730,N690 ,M334,SKD11,   SKD51.SKD61,

Other steel,316, 301, 303, 304, 420, NAK80, S136, 316Lect,other steel ,sus303,sus 304,ect other steel .

Aluminum: 6061, 5052, 7075 ,6082,ect ,Other Steel .

Plastic Materials& Additives and Fibers

With an extended range of plastic materials, you can choose what fits your needs perfectly.Each material has qualities that include heat resistance,

Impact strength, wear resistance,  and many more.Impact resistant: ABS, PMMA, PVC, PE, PC ;Wear-resistant: POM, PEEK, UHMW ;Dimensional stability: PBT, ABS, HIPS, PPS ;

Chemical resistance: PEEK, PP, PBT, PA, PE, LDPE ;Rubber like: TPU, TPE, Silicon ;Cost-efficient: PP, HDPE, LDPE；Cosmetic: ABS, PC, HIPS

Additives and fibers to enhance the quality and esthetics of standard plastic materials. Glass fibers 

The process increases the functionality and performance of the molded product.  UV absorbers , Colorants,Flame retardants,Plasticizers

Surface Finishes of Injection Molding

The process includes various steps, from injection mold tooling to entire plastic injection molding. Surface finishes of molds are processes typically carried out during production.

At our company, we perform the specific surface treatment after the injection molding process according to customer requirements.Glossy ; 

The SPI grade A1, A2, and A3 surface finishes are made with diamond buffing for a glossy and shiny surface finish; 

Semi-glossy ; The SPI standard B1, B2, and B3 grade surface treatment uses grit sandpaper paper to yield a semi-glossy surface finish;

Matte ; The C1, C2, and C3 SPI grade surface treatments use grit sanding stones to achieve rough texture and uneven surface:

Textured ; D1, D2, and D3 grade treatments use dry blast glass beads, and oxides for the surface finish to produce a very coarse and textured surface.
