COMPRESSION/RAM BENDING is a tube bending process we offer that creates a bend by hydraulically cycling a bend die in a downward motion into the tube. The tube is supported by a pair of wing dies that separate and rotate as the bend die moves through the center of the tube. This motion wraps the tube around the bend die, allowing the wing dies to support the tube on each side. This process is very fast and is great for high production. There are a variety of bend types available with this method of bending including controlled crush & knuckle bends. The maximum bend radius is 110° and is best for tight radius bends
