How Mold Texture and Surface Finishing Influence Injection Molded Part Quality

Beyond dimensional accuracy, the surface texture of a mold has a significant impact on the final look and performance of injection-molded parts. At Dongxinda Mould Technology Co., Ltd., we provide precise mold texturing and finishing services to meet both aesthetic and functional requirements across a wide range of industries.

Why Surface Texture Matters

The surface finish of the mold directly transfers onto the plastic part, affecting:

• Visual appearance (matte, gloss, patterned)

• Scratch resistance

• Paint or coating adhesion

• Release performance during ejection

Whether you need a high-gloss finish for consumer electronics or a textured surface for better grip in automotive interiors, Dongxinda offers the right mold finishing techniques to meet your needs.

Our Finishing Capabilities:

• High-Polish (SPI A1–A3) for transparent or mirror-finish parts

• EDM Surface Finishing for controlled texture and functional aesthetics

• Sandblasting & Bead Blasting for uniform matte finishes

• Laser Etching or Chemical Texturing for custom logos or grip surfaces

We also work with industry-standard texture codes like VDI, SPI, and Mold-Tech (MT) to match international client requirements.

Industries We Serve:

• Automotive interiors and controls

• Home appliances and power tools

• Consumer product housings

FAQs:

• Can you match an existing mold texture or standard?
  Yes, we work with VDI, MT, and custom samples to match client expectations.

• Will texture affect part release or cycle time?
  It can, but we optimize draft angles and ejection force accordingly.

• Is polishing available for transparent parts like lenses?
  Absolutely, we offer mirror polishing suitable for PC, PMMA, and more.
