Wire & Cable Machinery
A trade resource on wire and cable manufacturing machinery in India — extrusion lines, crossheads, screw & barrel design, haul-offs, and line setup for insulation and sheathing.
Who makes extrusion crossheads for wire, cable and tubing in 2027, the main crosshead types (fixed-centre, manual-centre, in-line, multi-layer), and what to check before you buy.
The leading wire and cable extrusion machine manufacturers and extrusion line suppliers for 2027, what each is known for, and how to choose a cable extrusion line for your product.
Solid, stranded, bunched and compacted conductors explained: IEC 60228 classes, concentric vs bunched construction, lay length, and why conductor quality matters to the extrusion line.
How an on-line spark tester finds pinholes and thin spots in cable insulation, AC vs DC vs high-frequency testers, where it goes on the line, and how to read the fault count.
Why keeping the conductor centred in its insulation matters for safety and cost, how eccentricity is measured on a running line, and what controls it during extrusion.
A practical comparison of PVC, PE and XLPE cable insulation — electrical and thermal properties, where each is used, and how the choice changes your extrusion setup.
From pay-off to take-up, a wire and cable extrusion line is a chain of coordinated stations. Here is what each one does and why line tension and cooling make or break the product.
The screw and barrel decide output, melt quality and which polymers a line can run. A practical guide to L/D ratio, screw design and why the right pairing matters for cable work.
The crosshead is where a bare conductor becomes an insulated cable. Here is how it works, why concentricity matters, and what separates a good crosshead from a troublesome one.
