Combined Drawing Machine

The combined drawing machine is used for producing bright steel bars with high efficiency and low production cost. It integrates drawing, straightening, cutting and collection processes into one continuous production system.
The equipment is suitable for stainless steel bars, carbon steel bars, alloy steel bars and special steel materials in multiple specifications. It helps improve bar surface quality, dimensional accuracy and production consistency.
The line can be configured according to drawing force, incoming material size, finished bar length and automation requirements. It is widely used in bright bar production, precision steel processing and metal material finishing plants.
Key advantages include high production efficiency, stable drawing performance, reduced handling, compact workflow and reliable finished product quality.
