1. )Lens Materials: PC
2.) Lamp Shade Materials: PC+UV Coating
2. Basic Demands:
1.) Lens: not allowed any texture and injection flow marks (lines) etc.
2.) Lamp Shade: limited concave point and convex point in each cone; blushing, black oxide coating, plating flow mark, plating point should less 0.15mm; Untouched Lamp Shade etc.
Lamp Shade Materials Choice:
1.PC materials which temperature resistance is higher than ABS.
2.PC working temperature can up to 120°C-150 °C;
3.In theory ABS working temperature can up to 120 °C,
4.Actually, when temperature up to 90°C, the lamp shade will out of shape
UV Coating Choice:
1.About the plastic plating, the technological process of UV Plating and vacuum plating is same.
2.Regarding surface hardness and viscidity, UV plating is better than Vacuum plating.
3.UV plating hardness at least up to 1H. If the hardness of Vacuum plating can up to HB, that's good.
4.For more detail, that depends on Plating factory if cut corners, like base coating and gloss coating.
5.Degreasing is very important, if you want to plate good plastic products. Like hand perspiration, need long-time supervision by yourself.
6.The cost of UV plating is four times more than vacuum plating.
