KYOSHIN VIETNAM CO., LTD.
Most recent update: 2025-01-25
Kyoshin Vietnam was established in March 1995, started production of metal stamping parts, over-molding parts and solenoid coils.
PR message
One stop services from tooling progressive dies, mass production of metal stamping parts, through heat treatment, electro plating, over-molded parts and solenoid coils.
There are a series of machine tools, Presses, Plating lines (barrel and reel-to-reel), Vertical injection molding machines and Semi-auto winding machines, we have long experiences of progressive stamped parts as terminals, deep-drawing parts and lamination cores, over-molded parts as Solenoid coils.

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, Contacts for circuit breakers, Busbars for EV batteries, Automotive wire-harnesses.

Tapping process in a progressive stamping die.
Tapping is performed in synchronization with the punching speed of the die.
Compared to an additional tapping process after pressing, it reduces man-hours and prevents forgetting to tap due to process skipping.
We can also deliver parts in embossed tape or radial taping for customers who use automatic mounting machines.
Our, RHYTHM group's Screw Terminal series are produced by this In-DIe Tapping process.

We have designed and made more than 800 progressive dies.
Max. die length: 1500mm
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.
