Mills for automotive tube industry

摘要

RAFTER Equipment Corporation manufactures tube mills, pipe mills, roll forming machines, cut-off machines, and other related mill machinery. For the automotive tube industry, in particular, the company has produced several mills. A common automotive tubing application is the production of exhaust tubing. This includes lighter wall 409 stainless steel using both high-frequency induction (HFI) and laser welding techniques. Another application is fuel line tubing, which is generally formed and welded at a larger 13mm diameter and subsequently cold-stretch reduced to a final size as small as 4.76mm OD. Automotive drive shaft tubing is another application.
