Build quality into the Manufacturing Process

The most important assignment is understanding current situation of production procedures. To know how procedures are working, SENGOKU's quality is getting higher and higher. Outside adviser teach all employees regarding PPM(Project Portfolio Management). Since we continuously check past-defected point, we are avoiding defected production. We thinks and installs that right operations results no defects. Currently, Our target qualification level is tenth of current defects numbers.


Actions for environment

Since 2008, we have been trying "Eco Action 21" which is established by Environment Ministry.
We contribute below points for nature environment
1. Reducing Carbon Dioxide
2. Reducing discharge of exhaust things

200t Line pacer

Facilities for mass production

Depending on customer needs, we changes manufacturing methods such as pressing or robotting. Processing weight ability is from 60t to 1250t.
Since we communicate with mold division, we can quickly repair or change mold.

  • 60t – 1250t pressing
  • 150t pressing
  • Line pacer ( Robot line)
  • Multi pacer (Robot line)

NC turret punch press,

We make small amount of production, special order product, and proto type product.  As computerized production, we make products by unpeopled and inexpensive production.

  • NC turret punch press
  • NC laser/turret punch processing
  • NC press braking

[2] Welding processing

To weld metals with several methods such as spot welding and TIG-MIG welding, seam welding.
