Features of a Quality Mandrel Bender for Sale

Plug-type Mandrel on a Mandrel Bender for Sale

When you are bending some jobs it only requires a mandrel plug.  Note that this mandrel type does not have any attached balls and linkage.  Plug-type mandrel can have a blunt end, round end, or tapered end.  It is often referred to as a mandrel shank. A mandrel is held in a fixed position while the tube is pulled over it.  Tube stretching is located on the outer radius of the bend. The mandrel then takes the force and supports the inner radius of the bend while firmly set into the bend die groove area. The plug-type mandrel on a mandrel bender produces a good quality bend when the bend specifications do not require additional support.

Ball-type Mandrel on a Mandrel Bender for Sale

See the mandrel diagram.  Unquestionably, your reason to seek a mandrel bender for sale is to employ a ball-type mandrel. You bend and it will become increasingly difficult to retain the material shape through the bend process .  It will lose ovality or flatten.

Wiper Die Importance on a Mandrel Bender for Sale

The material supported by a mandrel under compression on a mandrel bender will form wrinkles.  Tight radius, thin wall material will prove this.  Ultimately, it is the reason a ball mandrel and wiper die work together on a mandrel bender for sale.  The ball mandrel supports the inside of the material through a bend.  As a result, the balls stop the material from collapsing after it leaves the mandrel shank area.  Then the wiper die is used to prevent wrinkles.

Mandrel Extractor on a Mandrel Bender for Sale

On the condition that you bend with a mandrel, a mandrel extractor is a key feature on a mandrel bender for sale.  The mandrel extractor retracts and advances the mandrel on a mandrel rod.  This feature prevents the tube from forming around and gripping the mandrel balls. A mandrel extractor on a mandrel bender also helps minimize wall thinning and preserves ovality of the material.
