・Precision cold-headed parts
・Precision cold-headed parts
・Precision press parts
・Precision cut/turned parts
・Fasteners
・Various assembled parts

For fulfilling customers' requests, we have several patents of manufacturing methods such as swaging/caulking
technique to cold-headed, cold-forged, pressed and assembled parts which we developed by utilizing our experiences
gained from metal works for years. We, members of Production Technology/Development Room, act mainly for developing
new production technologies, and respond to customers' requests.

Blanks cut out from wire and bar materials are shaped by drawing, swaging and making holes. Compared to cutting
there is a great advantage over costs as the machining speed is faster and production efficiency is better.
Scraps are very fewer than those from cutting and it is fairly good to environment.

☆ Scope of production fields (including capabilities of our sub-suppliers) ☆
・ Parts-former: 1mm to 43mm in diameter of material, one to nine stages can be possible.
・ Forging press: 80 tons to 1500 tons

  Basically we manufacture products from board-shaped materials while on the other hand those by forging and
heading processes are made from coils and bars.

※ Excluding those made by a forging press and/or a secondary process with a press machine.
  Pressed parts are formed inside dies in the same manner as those made by heading and forging. Inside dies, board
materials can be blanked out, bent and drawn.

　As it is easy to machine parts automatically, it results in good production efficiency.
　That is, it contributes to the cost.

  Scope of Process
・ Capability of presses: from 10 tons to 600 tons
・ Capability of levelers: approx. from 0.15 mm to 9.00 mm

 

  In case that there are problems in shape, accuracies, and quantities, we manufacture them by cutting. Compared to
those made by heading and forging, as dies are not used, so we don't need to consider the cost which has to be spent at
early stages when dies are used.

  We also can make a variety of shapes by forming with lathes and multi-shaft machines.

  Scope of Process
・ NC automatic lathe: Up to φ52
※ Including facility at our sub-suppliers

We provide brake and transmission parts which become safety parts after respective parts partially being assembled at
the automatic line.

【Precision spherical machining by cold-heading and
forging】
・We can realize the mass production at lower prices by
using the precision spherical working technology.

Cases using technology above
・Parts for car-air conditioner
・ABS parts

【Precision blanking work with ordinary press】
・ We can realize "100% shorn section" which means
"no broken-out section" by using ordinary press.  
・ Cases using technology above  
・ Brake parts
・ Transmission parts  
・ Parts for seats
