Metal Casting Elbow Mould Die 5 - 80mm Wall Thickness Long Service Life

We Supply Pipe Fitting Mould Die To Pushing Carbon Steel Alloy Hot Forming Elbow 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 To Pushing Carbon Steel Alloy Hot Forming Elbow 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.

When the pipe section passes through the mandrel, the mandrel will be hold firmly via a holding mechanism.Then, a trolley, which may be hydraulically driven or mechanically driven via leadscrews, will be available to push the pipe section to move along the mandrel.Outside the mandrel, there is an induction coil which serves to heat the pipe section. After thorough heating, the trolley further pushes the pipe section to unload it, and thus a pipe elbow is created.Elbow sizing dies are specialised in sizing the dimension of the elbows after its first hot forming, the specification of the dies could be up to 2 metes in diameter, and it could also be manufactured based on the customised requirement and sketch.

Our Pipe Fitting Mould Die To Pushing Carbon Steel Alloy Hot Forming Elbow 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 To Pushing Carbon Steel Alloy Hot Forming Elbow 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.

And the mandrel and Pipe Fitting Mould Die To Pushing Carbon Steel Alloy Hot Forming Elbow material used in our factory has the characteristics of wear resistance, bending resistance and strong impact resistance, and the surface is bright and clean, suitable for the extrusion of copper, iron, aluminum, zinc, stainless steel and other metals.
