Quality Inspection
Inspection Equipment
Mitutoyo Surface Roughness Measurement
A surface roughness instrument measures textured molds and product samples.
German Gloss Meter Inspection
The gloss meter measures gloss on textured molds and product samples.
Light Transmission Inspection
A light-transmission meter measures the transmission rate of lighting samples.
Production Part Does Not Match the Approved Plaque
Possible causes include insufficient processing control, unsuitable inspection instruments, an impractical design or inadequate draft angle.
Suitable measuring instruments, controlled processing and early confirmation of the required draft angle with the texturing supplier help reduce this mismatch.
Gloss Variation
Gloss is influenced by the following factors.
1. The reflectivity of the plastic.
2. The final gloss level applied during mold texturing.
3. The reflectivity of the texture itself.
4. Injection-molding conditions, including cavity-side mold temperature and holding pressure.
Scratch Resistance
Scratch performance is influenced by the following factors.
1. The hardness relationship between the product surface and the scratching object accounts for 80%.
2. Texture selection matters because sandblasted, coated and film-transfer textures have different scratch performance.
3. The microscopic surface structure of the texture.
