the progressive die main advantage as below

1. it belongs to high-speed stamping tool.

2. it have high-efficiency and high-output.

3. the life span of die not less than one hundred million stamping times.

4. the process cost is very lower than single punch die.

5. it can be completed automatic stacks of single sheet.

6. it will can be saved the raw material .

About our product features

1. All punch chip use tungsten steel to stamping, The comprehensive service life span of the tool is not less than ten million stamping times. Tungsten steel edge should be grinded within 2 million stampings per time. but any details according to customer reuquires.

2. All price will precision count by my engineer and provide a competitive price for my customer. let all product have good value for money.

3. Consider to convenience,it's simple assembly to our mould.and lower cost for maintenance, special after-sales service and  regular maintenance and  grind punch chip.

4. We have a experienced design and manufacture team. and it's important to each details for us. we very care the finally and key requires. the good quality and warm service always  promise and  practice to my customers. meanwhile, we won the  affirmation and trust of them.

5. We can provide design drawings 2D and 3D files to my customers. and technology support.

6. We have complete test system and instrument. and Issued quality inspection sheet by Jiarun Quality inspection department.

7. As to the problem in the tooling manufacture process. main department will  organize discussion and solution.
