FORMING UP

FORMING DOWN

Holes through a pipe and a code. Drain holes, air holes or the like.

Forming process for making tubes. Used to guide or protect the code and pipe.

It forms tubes of various inner diameters.
After processing pre-hole, a tube is formed by one punch.

Shapes which do not fit in tool range such as φ300 can be processed by the continuousprocessing.

This photo is the example of burring for a variable resistor which is what we call a volume switch.

Forming tool forms a tube from the workpiece and makes a "rising part".

1）Please indicate the dimension(A)or (B), when you order
2）We recommend coated tools and heavy duty type dieset (in the case of upward) in order to reduce the trouble such as material which are difficult forming like stainless steel.
3）The diameter of pre-hole is as the following formula.
Estimate diameter = A + 1.8 x Material thickness - 2 x H
