We Supply Pipe Fitting Mould Die Sr Elbow Mandrel Head Sr Elbow Calibration Mould and all kinds of corresponding molds and dies for all our Pipe fittings Machine. The mandrel and corresponding induction coil for elbow forming machine. The mandrel is mainly engineered from 18-8, 2520, K18, stainless steel and alloy steel. It allows for production of pipe elbows with diameter between 21 and 1,620mm, curvature radius of 1D-3D, and wall thickness of 5-80 mm.
The mandrel for Pipe Fitting Mould Die Sr Elbow Mandrel Head Sr Elbow Calibration Mould comes with an ox horn shape, and is necessary during the hot forming process. Due to the special shape design, it enables diameter expanding while creating the bending.

Our Pipe Fitting Mould Die Sr Elbow Mandrel Head Sr Elbow Calibration Mould and elbow mandrel head materials are generally ZG1Cr18Ni9Ti, ZG3Cr20Ni14, ZG1Cr25Ni20Si2, ZG0Cr20Ni25, etc., the high temperature strength and wear resistance have gradually increased, and the price has also increased accordingly.

Pushed elbow mandrel head is divided into single curvature, double curvature and multiple curvature according to the radius of curvature.

For single-curvature, double-curvature, and multi-curvature mandrels, the thrust force is gradually reduced, and the production cost is gradually increased. According to the cross-sectional shape, it is divided into two types: circular cross section and elliptical cross section. The circular cross section is simple to make and the cost is low, but the ellipticity and thinning rate of the elbow are too large. Different, the ellipse and thinning rate of the push elbow are small.

Heiyan chose a mandrel with an oval cross section. According to whether or not there is a shaping section, it is divided into a mandrel head with a shaping section and a mandrel head without a shaping section. The Pipe Fitting Mould Die Sr Elbow Mandrel Head Sr Elbow Calibration Mould mandrel with shaped section is complicated to manufacture, high cost and long use time; the mandrel without shaped section is simple to manufacture and low cost.
