LBJZ-40 Chain Continuous Drawing Machine

LBJZ-40 chain continuous drawing machine is used for continuous drawing of metal bars and tubes. It is suitable for carbon steel, alloy steel, stainless steel and non-ferrous metal materials that require improved diameter accuracy and bright surface quality.
The chain drive system provides stable traction force and reliable continuous operation. The equipment can be used with pointing, lubrication, straightening, cutting and collection units to form an efficient drawing production line.
This model is suitable for medium and large production batches where stable drawing force, consistent product size and high surface quality are required.
Typical applications include bright bar production, precision tube drawing, special steel processing and raw material preparation for fasteners, machinery parts and automotive components.
