2k injection molding

2K Injection Mold

For an economical and efficient solution to mold two different plastic materials, we offer 2K injection mold tooling. This allows for a seamless integration of soft and hard plastics in a single product at save costs.

Surface Textures

The surface finish of the mold directly affects the appearance and quality of the final product. A smooth, polished mold surface results in a product with a better aesthetic appearance, free from imperfections like scratches or rough spots.
NameDescriptionSPIGuideR.A ValueTypical applications Injection Plastic material
GlossyThe diamond buffing process is employed to create polished and lustrous finishes on the injection mold, constituting the result of a grade. This procedure is notably time-intensive, with the choice of steel grade significantly influencing the ultimate outcome.A1Grade #3   Diamond0-1Lens /   Mirror – requires 420 SS materialAcrylic

A3Grade #15   Diamond2-3High   Polish partsABS, Acrylic. PS, Nylon, PC
Semi-glossyUtilizing grit sandpaper, B-grade finishes are employed to craft components featuring a subtle and matte surface texture, effectively eliminating all traces of tooling and machining imprints.B1600 Grit   paper2-3Medium   Polish partsABS, Acrylic, PP. PS, HDPE, Nylon, PC

B3320 Grit   paper9-10Med – Low   polishABS, Acrylic, PP. PS, HDPE, Nylon
MatteGrit sanding stones are employed in C-grade finishes to create an intentionally coarse and uneven surface. This process effectively eradicates tool and machining marks while enhancing mold release properties. The resulting mold surface exhibits a muted matte texture, devoid of any shine or sheen.C1600 Stone10-12Low Polish   partsABS, Acrylic, PP. PS, HDPE, Nylon, TPU

TexturedIn D-grade finishes, a combination of grit and dry glass beads or oxide is harnessed to generate an exceedingly rugged textured outcome, serving to conceal shrink marks and other flaws. The final appearance varies based on the material employed, potentially resulting in a satin or non-reflective finish for the products.D1Dry Blast   Glass Bead10-12Satin   finishABS, PP.
