The design features of the three-roll equipment include a lower row of double rolls for material feeding, and the upper roll is hydraulically lifted to control changes in material diameter.
Molds can be customized according to customer needs to process various profiles such as special-shaped alloys, rectangular steel, round steel, I-steel, H-steel, rectangular tubes, and round tubes.
It can bend metal profiles into arcs while keeping their cross-sectional characteristics basically unchanged, thus achieving the effect of bending workpieces into circles, cylinders, spirals, etc.
It is widely used in multiple industries such as boiler manufacturing, industrial manufacturing, aerospace, shipbuilding, automobile manufacturing, and chemical engineering.
The three-roll machine processes metal materials through the rotation of the rollers.
It features fast processing speed, which can significantly improve work efficiency.
It has low manufacturing cost and a wide range of applications.
Through the design of mold adaptability, it can process various materials with low mold costs.
The motor can rotate forward or reverse, facilitating multiple processing and correction to reduce errors.
It has a simple structure, is robust and durable, and easy to maintain.
High precision and good stability, which can effectively solve the problem of precision reduction of the hydraulic system over time.
It can better ensure the horizontal alignment of the processing rollers when processing profiles.
It can further correct the size of the processed profiles.
With over 20 years of deep cultivation in the industry, the company has formed four mature business segments:
