They are highly engineered systems that combine optical performance, regulatory compliance, manufacturability, thermal management, and long-term reliability. Some of the key plastic components that make up a modern automotive rear lamp assembly include: ๐Ÿ”น Outer Lens – Provides optical function and styling signature while meeting regulatory requirements. ๐Ÿ”น Reflector / Light Guide – Controls and distributes light for brake, position, indicator, and reverse lighting functions. ๐Ÿ”น Light Guide / Optical Elements – Enhance optical performance and ensure uniform light output. ๐Ÿ”น Housing – Provides structural support, protects internal components, and enables feature integration. ๐Ÿ”น Brackets & Supporting Components – Ensure accurate...

But near the gate, silver streaks appeared across the surface. Those are Splay Marks — one of the most common cosmetic defects in injection molding. Splay marks occur when moisture, trapped gases, contamination, or degraded resin travel with the melt and stretch across the surface during filling. The result is a silver, fan-shaped pattern that becomes highly visible on automotive interior and Class-A surfaces. Why it happens: ① Moisture in resin ② Excessive injection speed ③ Contamination in the barrel ④ Overheating and resin degradation How to prevent it: ✓ Dry resin to the specified moisture level ✓ Reduce injection speed when required ✓ Purge the barrel thoroughly during material changes ✓ Optimize barrel temperature settings ✓ Maintain proper back pressure for a homogeneous melt Splay marks are not a surface proble...
