D600 Front Combination Lamp Bezel

Challenge:
The main challenge was to achieve a bright and uniform mirror-like surface on the front combination lamp bezel. As a visible part of the appearance, the surface required strict quality control. Any flow marks, weld lines, sink marks, scratches, polishing marks, or uneven gloss could directly affect the final visual quality and overall assembly appearance.

Solution:
We applied high-precision machining and fine polishing to the mold surface to meet the mirror-finish requirement. The gate layout and cooling system were optimized to improve material flow and reduce surface defects. During mold trials, we fine-tuned the mold temperature, material temperature, injection speed, holding pressure, and cooling time to ensure a stable high-gloss appearance and consistent mirror-like surface quality.
