To get the best results, use the abundant of ejector pin is very important.

In the design, should consider the ejector pin with sufficient area, in order to prevent the compression surface of resin. At the same time, the ejector pin should be placed properly, don't make the product produces stress. Top cover for bulge parts, recommended. When the correct design and polishing, GE resin in general there is no need to use the external release agent.
