Fin punching die for shell and tube heat exchanger

Fin punching die outline

This is a fully automatic and continuous production fin punching die, which is the key mold for making aluminum or copper fins of tube and shell heat exchangers, It is composed of multiple independent small molds combined to form a complete automatic mold,

This type of mold has many advantages, such as adaptability to high-speed production, ultra-long service life, and simple combination arrangement to produce different sizes

Due to the many sizes of the diameters of tube and shell heat exchangers in industrial applications, in order to meet the multiple application scenarios in the market, we have designed a quick installation device for arc cutters for fin punching die. In production, fins of different sizes can be produced by simply replacing the cutters, which can save a lot of money for factories

Fin punching die advantage

1. The width and length of the fins can be freely changed without changing the spacing and diameter of the holes. One mold can produce multiple products, which saves a lot of money for the factory

2. This fin-punching die uses high-quality materials, and the key parts have undergone vacuum quenching to a hardness of 62. Its service life is very long

3. Our engineers have an average working age of over 16 years. Our mold design is reasonable, compact, and aesthetically pleasing, making it perfect for various stamping machines

4. Our factory manufactures every critical component, effectively controlling the quality of the mold and providing effective guarantees for rapid delivery
