Pulley / OTO Type Wire Drawing Machine
Pulley OTO wire drawing machine is an economical continuous‑drawing solution.
Reference base model: LW6‑550 six‑pass unit.
Standard configuration targets low‑medium carbon steel for nail wire, binding wire and welded mesh wire. With customized cooling, die‑box and transmission upgrade, it can also process high‑carbon steel, stainless steel, copper and aluminum alloys.
It adopts reliable purchased‑brand reducer, easy operation and low spare‑part cost for mass‑production scenarios.

Frequently Asked Questions
1.What wire sizes can this OTO pulley machine handle?
Answer: Our reference LW6‑550 model runs from Φ6.5 mm inlet down to Φ2.5 mm finished wire. Wider wire range Φ2.5‑10 mm inlet / Φ0.4‑6 mm finished can be realized by customizing drawing passes and hardware. Please share your wire specification for assessment.
2.How many drawing passes do I need for my wire?
Answer: Drawing passes are customized based on raw wire diameter, finished wire size, material and target speed. Send us your wire specification, we will calculate the matching passes.
3.What supporting equipment do I need with this machine?
Answer: Common matched equipment includes wire pay‑off stand, take‑up spooler, wire pointing machine and descaling machine. We can recommend supporting units together according to your production line layout.
4.Can this pulley machine draw high‑carbon steel, stainless steel or copper‑aluminum wire?
Answer: The standard machine is optimized for low‑medium carbon steel. It can process high‑carbon steel, stainless steel, copper and aluminum alloys, but cannot run directly with standard configuration. It needs technical evaluation plus upgrade on cooling system, die‑box and transmission components. Please provide your wire specifications for our assessment.
