System advantages by piercing nuts
A paying investment
Factors, such as degree of utilization, reliability, maintenance, failure frequency, investment and the cost of logistics are critical to the economy of a joining system.
Here, the system advantages of PIAS® come into play in comparison with conventional methods, such as welding.
Additional cost advantages, such as lower energy input, shorter transport distances, no rework, etc., are not considered in the cost table below.
Also left out of consideration in the following example are the advantages of low investment.
Cost comparison | Welded nut | Punched nut |
| Material each nut | 0,02 | 0,0357 |
| Production time 12 sec. each part, cost rate c. 45€/hr. | ||
| Production cost | 0,115 | |
| Tool wear | 0,00155 | 0,00085 |
| Cost of 1 nut | 0,13655 | 0,03655 |
| Saved on 1 nut: 0.1 Euro | ||
| For 300,000 nuts a year the cost saving is approx. 30,000 Euro per year! | ||
