Features

1. Progressive die is a multi-task sequential die. It can include punching, bending, deep drawing, forming and many other processes, so it has higher production efficiency than compound die, and can produce quite complex stamping parts.

2. Progressive die operation is safe because manpower does not have to enter the hazardous area.

3. in the progressive die design, process can be dispersed. Because the process does not have to be concentrated in the same station, there is no problem of "minimum wall thickness" in the compound mold. Therefore, the mold is relatively strong and has a long service life.

4. the progressive die is easy to realize automation, including automatic feeding, automatic output (material), automatic riveting; 

5. the waste of the progressive die will drop downwards, and the work piece will come out downward or exit from the side of the mold. Therefore, high-speed presses can be used for its stamping, such as terminal dies, high-speed dies etc. 

6. in general, one set of progressive die uses one press machine, so the use of progressive die can reduce the press quantity, workshop area, semi-manufactured goods transportation and storage area, and manpower required for stamping.

Metal Pall Rings

Metal Pall Ring has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiency and so on. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.

It is made of materials like carbon steel, stainless steel or Aluminum alloy, etc.
