Tool systems
There are two fine blank tool systems in use:
a) tools with a fixed punch (sometimes called "three plate tools")
b) tools with a sliding punch (sometimes called "two plate" tools)
Sliding punch tools are easier to design and manufacture so they are cheaper than fixed punch tools. But for some applications, sliding punch design can weaken the tooling elements and shorten die life. Costs for sliding punch tools are in the range of $5000 to $15,000.
Fixed punch tooling has a more robust tool design which makes it the choice for heavy blanking pressures and long runs. However, the cost is prohibitive for short to medium run tools. Costs for fixed punch tools are in the range of $10,000 to $30,000.
As you can see, fine blank tooling is more expensive that conventional stamping tools. This is due to the need for expensive tool steels and extreme accuracy in manufacture.
Partech has developed a low cost tooling system for small parts, so if your applications will fit inside a 9 inch circle, please contact us for a competitive quote.
