Enhancing Glossiness in Household Appliance Molds

How to Enhance the Glossiness of Injection-Molded Parts in Household Appliance Mold Manufacturing?

It’s actually quite simple. Here’s a brief guide from DAYIN Plastics on improving the glossiness of ABS injection-molded parts through household appliance mold manufacturing. You can achieve this by optimizing mold processing quality, controlling processing temperatures, using appropriate release agents, and performing surface treatments like polishing.

Mold Cavity Processing Quality:

If the mold cavity has scratches, micro-holes, wear, or roughness, it will inevitably affect the glossiness of the plastic parts. Therefore, it is crucial to process the mold carefully, ensuring that the cavity surface has minimal roughness. Polishing and chrome plating can be applied if necessary.

Surface Cleanliness:

If the cavity surface has oil stains, water marks, or excessive release agent, it will result in dull and lackluster plastic parts. Thus, it is essential to clean any oil and water stains promptly and limit the use of release agents.

Draft Angle:

If the draft angle of the plastic part is too small, it may cause difficulties during demolding or require excessive force, which can damage the surface gloss. To prevent this, the draft angle should be appropriately increased.

Mold Venting:

Poor mold venting can trap gases inside the mold, affecting the glossiness of the part. It is important to inspect and correct the mold’s venting system to ensure effective ventilation.

Gate and Runner Design:

If the cross-sectional area of the gate or runner is too small or changes abruptly, the melt may experience excessive shear forces during flow, leading to turbulence and affecting glossiness. Therefore, the cross-sectional area of the gate and runner should be appropriately enlarged to ensure smooth flow of the melt.
