Ratio of Effective Working Length To Hole Diameter

Sep. 25, 2018

The compression ratio of ring die that maybe the Customized Ring Die is the ratio of effective working length and hole diameter of ring die.

The material of ring mould is carbon steel, alloy structural steel or stainless steel. The material of ring mould can be selected according to the corrosiveness of materials and the working strength of ring mould.

The ratio of the inlet area to the cross-sectional area of the die hole is compression ratio, and the compression ratio and compression ratio are easily confused.

After several hours of use, due to material friction, the original inherent pore size becomes larger, the effective compression length remains unchanged and the compression ratio decreases. Under the same conditions of materials, steam, etc., the hardness of the production feed gradually decreases and the ring mold is scrapped.
