1. The replaceable design of the punch insert leads to lower usage costs:

2. When the size less than 2.0mm, the tool  needs to be designed as fully guided.

3. When using a multi-hole die, it is essential to avoid repeated stamping of the same hole.

4. If the step distance is too small during processing, it may cause damage to the lower die. It is recommended that the step distance be larger than the hole diameter.

5. To ensure the strength of the lower die, the distance between holes (including the thickness of the sheet) shall not be less than 3.2mm, or the distance between holes shall be greater than twice the thickness of the plate.

6. Multi-hole molds come in both integral and split inlaid structures, and the mold structure can be designed according to the processing requirements of customers.

7. Generally, customers only need to purchase the punch assembly, the lower die, and the discharge plate (PDS).

8. If the customer's internal guide sleeves are insufficient, it should be specified when placing the order that a separate guide sleeve assembly needs to be ordered.
