Main components of die manufacturer:

1. Standard components and specifications

The following matters shall be considered in the selection method of standard specifications for moulds: (A) When the specifications used are not limited, the high-level ones shall be used. (B) In principle, the standard number shall be adopted. (C) If the standard part of the mold does not have this size, it shall be processed by the closer one.

2. Design of punch

The punch can be roughly divided into three parts according to its functions: (A) The cutting edge tip of the processing material (the cutting edge has irregular shape, square shape, round shape, etc.). (B). The contact part with the punch fixing plate (the fixing part or the handle, whose section shape is irregular, square, round, etc.). (C). The connecting part (middle part) between the blade and the handle.

The design criteria of each part of the punch are briefly described from (A) the length of the cutting edge, (B) the grinding direction of the cutting edge, (C) the fixing method of the punch and the shape of the handle.

3. Design of punch fixing plate

The thickness of the punch fixing plate is related to the size of the die and the load. Generally, it is 30~40% of the punch length, and the length of the punch guide should be 1.5 times higher than the punch diameter
