Cross head
Supermac has introduced the new series of Cross Heads which are compact in design and offers the uncompromised accuracy of distributing the extruded material over the conductor. The new series of cross heads are meant for insulation & sheathing application of round, Sector shape & multi core cables. The wide range of models are available in Fixed Centering, Manual centering, Single Cross Head, Dual Cross Head and Triple Cross Head.
The in house production capabilities at Supermac enable us to achieve the high accuracy in machining of cross head parts which in turn given our customer nearly the perfect product suiting their application. The cross head components are made of special alloy steel & are vacuum heat treated. The most important part of the cross Head is its melt distributor. Its task is to uniformly distribute the molten polymers over the conductor. Various melt distributor profiles are designed and developed through computer software's to suit the challenging demands of new generations of polymers like PVC, Nylon, XLPE, ZHFR and FRLS etc.
The Cross Head is supplied with internal cartridge heating system, which helps in fast heating of head & conserve the heat energy from external losses.
FAQ
Cross head is an important function in the extrusion process of cables. In this process, a wire or multiple wires are aligned together to form a cable. The process of sheathing an inner layer of polymer on the cross headed wires that ensure the alignment stays intact, is also done under this process. It is only after this level, that the final outer layer of rubber is coated on a cable.
In a crosshead machine, a wire or a group of wires is passed through the machine. The machine aligns these wires to form an inner layer of the cables. As soon as the wires are aligned, a layer of polymer is added to the structure to keep the alignment intact. The most important part of the cross head is its melt distributor. Its task is to uniformly distribute the molten polymers over the conductor.
The varieties of cross heads that are offered by Supermac are:
- Fixed Centering
- Manual centering
- Single Cross Head
- Dual Cross Head
- Triple Cross Head
