How many annealing cycles does an automotive headlight lens require?
In automotive headlight manufacturing, only the lens (the polycarbonate/PC light-distributing cover) undergoes a single annealing process;other components (such as the reflector and housing) do not require this treatment.During injection molding, the polycarbonate (PC) lens develops residual internal stress due to uneven cooling, making it prone to cracking or warping under temperature fluctuations or impact. Annealing […]
