Product Abstract:

Louver Tool Closed Type/Louver Tool Openned Type 1.Mold is correspondent with plate thickness, different plate thickness require different tooling. 2.Different plate thickness, different mold size, only need to change inserts, save purchase cost. 3.Process program should pay attention on the plate moving direction, reserve enough unloading time. 4.Non-forming pitch (A) must be larger than 3 times plate thickness, width is 2-3 times height not including plate thickness. 5.Forming height: tC.S is 3-4 times of sheet thickness, Alum is 2-3 times and S.S is 1-2 times sheet thickness. 6.The higher the forming height, the more serious the reverse pulling phenomenon. 7.For thickness that is less than 1.2mm sheet, the R should be larger than 10mm so as to avoid angle part from splitting.

Product Description

Louver Tool Closed Type/Louver Tool Openned Type


1. Mold is correspondent with plate thickness, different plate thickness require different tooling.

2. Different plate thickness, different mold size, only need to change inserts, save purchase cost.

3. Process program should pay attention on the plate moving direction, reserve enough unloading time.

4. Non-forming pitch (A) must be larger than 3 times plate thickness, width is 2-3 times height not including plate thickness.

5. Forming height: tC.S is 3-4 times of sheet thickness, Alum is 2-3 times and S.S is 1-2 times sheet thickness.

6. The higher the forming height, the more serious the reverse pulling phenomenon.

7. For thickness that is less than 1.2mm sheet, the R should be larger than 10mm so as to avoid angle part from splitting.

For punch body, we produce it with SKH-51. It has another name of high speed steel. This is an alloy steel with complex composition. It includes tungsten, molybdenum, chromium, vanadium, cobalt and other carbide forming elements. The total amount of alloying element arrive to 10%-25%. On the condition of hot heat (around 500℃) that emerging with high-speed punching, it will keep high hardness and HRC can arrive above 60. This is also the main feature of high speed steel which is called red hardness. 


This material can make the toolings more durable and wear-ressistant which will cause a longer tooling life.


The die material we choose is Japanese imported special steel DC53, which is a new type tooling steel improved from SKD11. This material overcome the weakness of SKD11’s insufficient tempering hardness and toughness. The strength and hardness is excellent while doing heat treatment, HRC can arrive to 62-63.

DC53 steel’s toughness in cold die steel is more prominent. Tools made by DC53 will have little cracks and cracking which will greatly improve the tooling life.
