Challenge:
The main challenge was to achieve a smooth and uniform mirror-like surface on the fog lamp inner lens. Since this part is related to light transmission and optical appearance, the surface required strict quality control. Any flow marks, weld lines, sink marks, scratches, polishing marks, or uneven gloss could affect both the final appearance and the lighting performance.
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, mold temperature, material temperature, injection speed, holding pressure, and cooling time were fine-tuned to ensure a stable mirror-like surface, good optical clarity, and consistent appearance quality.
