Hydraulic Decoiler Straightener GL-H (0.4-4.5mm)

The SUNRUI GL-H series is a hydraulic decoiler straightener designed for manufacturers with limited production floor space. By integrating coil unwinding and precision flattening into a single compact unit, it eliminates the need for separate decoiling and leveling equipment—reducing installation footprint by up to 40% while ensuring consistent material flatness and stable material flow.

This space-saving design is more than just compact. The straightening section features 7 precision-ground rollers (4 upper / 3 lower), manufactured from GCr15 bearing steel with deep hard-chrome plating and mirror polishing. Surface hardness reaches HRC60°±2, delivering exceptional wear resistance and low surface friction that protects sensitive material finishes from scratches and surface defects.

The leveling section incorporates a worm gear adjustment mechanism with a dial gauge for quick, accurate straightening point positioning—ensuring batch-to-batch consistency across full production runs.

In metal stamping, material flatness determines part quality. The SUNRUI GL-H series hydraulic decoiler straightener addresses two critical challenges simultaneously: limited plant space and inconsistent material quality.

1. Solve Space Constraints

   
   The short-space, integrated design eliminates the need for separate decoiling and leveling stations. No intermediate material buffer zone is required—making automation upgrades feasible even in older, space-constrained facilities.

   
   

2.  Eliminate Quality Inconsistencies

   
   Whether processing stainless steel, galvanized sheet, aluminum, or high-strength steel, the GL-H delivers consistent flatness across the full coil width. With 7 precision-ground straightening rollers, hardened to HRC60°±2 and hard-chrome plated,the machine ensures:

• Up to 40% floor space savings

• Significantly reduced scrap rates from material distortion

• Lower rework costs and improved first-pass yield

• Reduced initial investment vs. purchasing separate units

• Lower long-term maintenance and energy costs
