Tungsten Carbide Mandrel

Tungsten carbide mandrel is a smaller version of the mandrel, the mandrel standard carbide overall length always are less than 100mm, the main length is 80mm. But if the customers have special required about the size, we could provide the mandrel according to different customer requirements. Tungsten carbide mandrel is mainly used in the pressing direction of the mandrel in the compact or the sintered body forming mold parts Profile.

Application

Ordinary materials of mandrel are mainly for the production of seamless pipe when inserted into the body with the interior annular grooved rolls or the like so that the pipe forming tool. Continuous rolling machine rolling, pipe rolling ramp extended period type rolling machine rolling, you must use a mandrel head pipe and tube when cold-rolled cold drawn.
Tungsten carbide mandrel, as special nature of the material, and carbide materials prices are relatively high, so it is usually used in the main oil bearing plants, metallurgy plants, tool factory and relatively high-end products.

Features
1. Mirror-polished, surface finish to Ra0.02μm.
2. The outer diameter of the precision required to achieve 0.001mm, roundness to within 0.5μ.
3. Size can be made according to customer specified to make a variety of specifications; the minimum outside diameter can be processed Φ0.2mm size.
4. Tungsten carbide mandrel is characterized by material wear, very suitable for oil-bearing plants, metallurgy plants, and tool factory.
