What specific benefits can in-mold tapping machines bring to stamping factories? Which company does in-mold tapping well?

The stamping and tapping process is formed in one step, which simplifies the factory production process, reduces transportation in the manufacturing workshop, saves labor costs, and promotes the improvement of the company's mold manufacturing level, etc.

However, in-mold tapping is not the most suitable choice for tapping stamping products. For some products whose production speed is higher than 120 times per minute, using in-mold tapping will reduce the production speed. In addition, improper use and maintenance of the in-mold tapping machine is also very troublesome, and the stability of the mold is relatively high. The mold for installing the in-mold tapping machine must be a precision mold.

There are many ways to solve the problem of tapping of stamping products, and they are not necessarily less efficient and stable than in-mold tapping, and can even be better. For example, using a vibrating disc-type automatic thread tapping machine, the small hardware previously used can tap more than 20,000 pieces of hardware with a single head in an 8-hour shift. For some products that are produced more than 120 times per minute, tapping can be carried out through continuous wiring. The first punch press punches out the flanging hole of the product, and the product comes out of the mold and enters the tapping machine. It can be stamped accordingly. The number of heads of the tapping machine is designed according to the speed, such as two heads, three heads, four heads, etc. After tapping, the material belt enters the mold of another punch machine to punch other characteristics of the product. Through practice, it is much better than in-mold tapping.

Ten years ago, a Taiwan-funded factory in Guangdong had a relatively mature in-mold tapping machine. At that time, even the punch press was shipped from Taiwan to the mainland. Later, a plate in the in-mold tapping machine was damaged by wear. At that time, the cost of repairing a plate was more than 10,000. With the spread of in-mold tapping technology in recent years, there are many products on the market. There are many different manufacturers, ranging from more than 10,000 units to 60,000 to 70,000 units, so you have to choose a manufacturer that entered this field relatively early. The one in Dongguan that I contacted ten years ago seems to be Morikawa Machinery. The brand of tapping machine is Kornoson.
