Space-Saving Design with Robust Construction
The compact "short-space" design was developed specifically to meet the needs of manufacturers with limited production floor space. The system reduces overall line length and eliminates separate loop pits or buffer zones, making it ideal for space-constrained workshops .All straightening rollers are manufactured from GCr15 bearing steel, heat-treated to HRC60°±2, hard-chrome plated, and precision-ground for extended service life and consistent flattening performance . The heavy-duty steel frame ensures durability and stability under continuous operation.
Easy Operation & Maintenance
The user-friendly console and intuitive controls allow for quick setup and adjustment. The straightening gap is easily adjusted via a worm gear mechanism with a dial indicator for precise setting . The unique flip-top design allows workers to clean the straightening rolls easily, reducing downtime and ensuring consistent performance .
Customizable Solutions
SUNRUI offers extensive customization, including special roller materials (e.g., PU rollers for soft materials like aluminum or copper to prevent scratching), film collection devices for sensitive surfaces, and various control system options .

SUNRUI 2 IN 1 decoiler straightener --- Frequently Asked Questions
1. What is a Decoiler Straightener?
A Decoiler Straightener is a 2-in-1 coil handling machine that combines an uncoiler and a straightener into one compact unit. It unwinds metal coils and removes coil set before feeding the material into the next production process, such as stamping, roll forming, or slitting.
2. What are the advantages of a 2 in 1 Decoiler Straightener?
A 2-in-1 machine saves factory space, reduces installation costs, improves coil feeding stability, shortens material travel distance, and increases production efficiency.
3. What materials can the SUNRUI Decoiler Straightener process?
Our machines are suitable for:
Carbon Steel
Stainless Steel
Galvanized Steel
Aluminum
Copper
