refers to a die structure in which a press machine completes blanking, punching and other processes in one stroke.

Compound Die Classification

(1)BlankingCompound die manufacturing: such as blanking and punching or cutting and punching etc.

(2)Forming compound die: such as bending, extrusion etc.

(3)Blanking and forming compound die: such as blanking and deep drawing; punching and flanging; deep drawing and trimming; blanking, deep drawing, punching and flanging etc.

 

Compound Die Set Features

1. Production efficiency is highly increased.

2. Quality of stamping parts improved

3. Concentricity error of compound die is within +/-0.02 ~ +/-0.04mm.

4. High requirements for die manufacturing accuracy

 

Because the compound die needs to complete several stamping processes in one die, the die structure is generally more complex than single station die. and the components require no interference, accuracy, and reliability during operation which requires a high manufacturing precision. Therefore, the manufacturing cost of the compound die is also increased, the manufacturing cycle is relatively extended, and the maintenance is not as simple as the single process.
