Usually after injection molding, the head and the product are connected through a gate. The workers need to trim the gate. The labor intensity is high and the construction is not beautiful.

In-mold heating is an automatic mold injection molding process that cuts or breaks the gate before the plastic mold is opened, so as to realize the separation of parts and materials after the plastic mold is opened.

The existing solution is to cut the gate from the top plate when the mold is opened, both methods are cut after the mold is opened, because the plastic has cooled, the gate surface after cutting is not beautiful, the product quality does not go up, it still needs several manual trimming to trim the gate flat, the labor intensity is still large, increasing the labor cost.

In-mold hot die has been widely used in various industrial developed countries and regions in the world. This is mainly because the in-mold heat mold has the following significant characteristics:

1, reduce the impact of artificial quality of products

In the process of in-mold hot mold molding, the automatic gate separation ensures the appearance of the gate separation, and the result is a consistent quality part, while the traditional manual gate separation process cannot guarantee the appearance of the gate separation. Therefore, many high-quality products on the market are produced by in-mold hot molds.

2, reduce the molding cycle, improve production stability

The automation of in-mold hot forming avoids useless human actions in the production process, and the fully automated mechanical cutting of the product ensures the consistency of quality, which has an incomparable advantage over the traditional mold in the mass production process of the product.

3, the mold gate separation automation, reduce the dependence on people;

After the traditional plastic mold is opened, the product is connected with the gate, which requires two processes to be manually cut and separated. The hot mold in the mold will separate the gate before the opening of the mold, eliminating the subsequent processes, which is conducive to production automation and reducing dependence on people.
