Seki Press Co., Ltd. Main Factory

Blanking/shaving method

A shaving method bores normally is hole in the first step (blanking) and then performs shaving in the second step
With our method, we can blank and shave simultaneously.
Our technology has been adopted in a variety of fields, including automotive parts.

Drawing and molding technology (shaving applied)

By applying our company's shaving technology to drawing, we've achieved the creation of 2-mm plane surfaces from drawn edges.

Stainless steel Shaving (progressive line products)

We offer and provide high accurancy items as they move along the line for customers

SUS materials, central hole shaving

Shaving parts

We change U-shaped grooves at each side from machining to shaving, reducing costs and creating edges at least as good as those made by machining.
Squareness and flatness precision are also sufficient.
S65CM material

Elliptical hole shaving

Regular methods drawing holes are not good for maintaining precise dimensions at four points in a central elliptical hole, so we fulfill customer needs with our precision shaving process.
Material: SUS316

WARISAKI -the World’s first technology- press processing to split metal

This is a promotion video shows our news technology WARISAKI.
We acquired domestic patent and applied for Taiwan Patent.

How would you use this technology?

WARISAKI technology (Brass)

We have succeeded in splitting a plate of brass.

[WARISAKI] T-shape brackets

We produce T-shape bracket only by Press processes.

meterials available: Copper, Aluminum, Steel, Brass.

** the reference photo is Steel and Brass.

[WARISAKI] SUS304 Punching metal

We succeeded in splitting Stainless steel (punching metal) by WARISAKI press work.

Integrated press processing product of complicated 3D shapes by WARISAKI (split processing technology)

This is the world’s first technology to succeed manufacturing the product from splitting technology (Patent No. 5165806, International and Taiwan patent pending) to Heming processing in the progressive die. It achieved the shortening of the lead time and reducing the cost from the conventional construction method.

Materials: Steel, Aluminum, Copper
It has various uses
      ・Complex 3D shapes by splitting and hemming
      ・Jointing dissimilar metals
      ・T-shape brackets

The Splitting technologies of the titanium and the stainless steel are now on trial.

Integrated press processing product of complicated 3D shapes by WARISAKI (split processing technology)

We utilized splitting (Warisaki) processing technology and succeeded to manufacture integrated cast processing products of complicated 3D shapes by the metal press.

・Shifting from previously manufacturing by welding and forging to now process by products by the metal press enabled us to
1) Reduce cost (maximum of 75%)
2) Shorten the lead time (by one quarter)
3) Greatly improve the quality stability due to no connection such as the welding construction method

The round shaped metal fittings applied Splitting (Warisaki) processing technology

We provide a round-tip product by applying splitting (Warisaki) processing technology.

・To change the material shape from flat metal to round metal!
・To put the round shaped part to the flat metal directly!

We can cope with a specially ordered product if the diameter of the round shape is within the dimension which can be put on the press.
We constantly handle with the extending of the materials.
