Parts feeder will automatically provide contacts/nuts/self clinching fasteners into progressive stamping dies one by one, then caulking it into stamped parts made of copper alloys.
In-die caulking process enables us to reduce additional caulking/welding processes after stamping. It also minimizes the risk of operational errors.
Application: Contacts for automotive switches and circuit breakers, Busbars for EV batteries, Automotive wire-harnesses.

Tapping in a progressive stamping die.
Tapping is performed in perfect synchronization with the punching speed of the die.
Compared to a separate tapping process after stamping, this method reduces labor hours and eliminates the risk of missed operations due to skipped processes.
We can also supply parts in embossed tape or radial taping formats, tailored for customers who use automatic mounting machines.
The RHYTHM Group’s Screw Terminal series is manufactured using this advanced in-die tapping process.

We have designed and made more than 800 progressive dies.
Max. die length: 1500mm (Maximum machine tonnage is 220-ton)
For drawing parts, terminals, busbars, brackets, lamination cores, In-die tapping, In-die caulking/riveting etc.
Total 20 skilled workers and die-designers.
Depends on the numbers of orders, there are cases that we use outsource to meet customers required lead time.
