How do you demould the plastic test, do you know? -Huaqiang Electronic Network

The plastic test molds are generally a whole. Only the bottom of the test mold has a small hole. How to drag the test mold out completely is the most concerned issue for everyone. Here are a few simple steps:
First, the inside of the test mold should be brushed with oil once before injection molding to facilitate the later demoulding;
After brushing the oil, a small piece of waste paper is placed at the small hole of the test die to protect the test hole from being blocked by concrete;
Finally, the air pump and the test mode are linked, so that a complete test mode is dragged out. It is best to buy it together with the air pump when buying the test mode. If the test mode is more and the gas pump seller will give it. If there is no air pump, it can only be ejected from the bottom hole with steel bars and other things, and it is smashed out on the edge of the test piece or on a platform, then the plastic mold is inverted, and the plastic mold is not forced. Too large, otherwise it will damage the test mode.
