Process Planning

Osaka Seiko cooperates with customers discussing part shape,size,accuracy,material from the development stage of new products.
It is one of Osaka Seiko’s attributes to not only design the forging dimensionally, but to suggest material and production process of CHQ wire.
This makes it possible to produce precision cold forging parts and to meet customer’s requirements and characteristics of product which customer produces.
We challenge the underdeveloped and frontier areas of cold forging processes.

Equipment

Osaka Seiko provides a wide range of production capability fromφ2 toφ55 material processing formers which covers all types of automobile parts produced from CHQ wire.
In addition to meet the specific needs of our customers for more complex shapes and larger, we have 1100KN, 2500KN and 6300KN Press machines.
