First of all, we all know that flashing can also be called flashing and flashing, which usually occurs when the front and back molds are opened and closed. For example, the parting surface of the injection mold, the gap of the insert, the hole position of the ejector, and so on. If the flash is not handled in time, it will cause partial collapse of the injection mold or even damage the mold in severe cases.

Factors leading to injection mold flash:
1. Improper adjustment of the mold clamping device of the injection molding machine will cause the mold to fail to achieve the required parallelism, which will affect the phenomenon that the seal on one side of the injection mold is not tight, and the seal on the other side is firm. Will easily overflow.

2. The parallelism of the injection molding machine itself has a certain deviation, and the uneven distribution of the tie rods will also cause the mold to be unable to close tightly and cause overflow.

3. The fixing ring of the injection molding machine is worn out, the screws are severely worn, the injection volume in the barrel is insufficient, and the cushion is too small, which will also cause overflow.

4. The accuracy of the parting surface of the injection mold is poor, the movable template in the mold is deformed and warped, foreign objects on the parting surface and the protruding sliding burrs around the mold base can also cause injection overflow.

5. When the mold design is unreasonable, the opening position of the mold cavity is offset too large, which will cause the unidirectional tension of the injection mold to be super normal during the injection molding process, and it is easy to produce flash.
