Nikko Sangyo Co. has been utilizing the bulgeforming principle as their main process to manufacture from metal tubing or sheet metal under very high fluid pressure, products difficult or impossible to manufacture by the current conventional casting or punch press processes.
Our Bulgeforming process started in 1963, applying Japan MITI patented invention which has more recently expanded extensively, particularly in Europe and in North America to the Automotive Industries. Our organization, on the basis of many years of experience, has designed and developed our machines complete with necessary associated software. Our hope and our effort is to be able to propose to many customers the variety of difficult to manufacture products with reduction in weight, unbelievable reduction in cost while retaining very high quality in a very safe environment.

1)
|
The above processing has general limitation but it is possible to process any product beyond the above formula, all depend on the shape, so we look forward to receiving you enquiries.
|
|
2)
|
Materials unsuitable for Bulge-Forming are Steel with high carbon/Low Elongation, and others with High Hardness/Low Elongation.
