01

High-Hardness Alloy Steel Forging Material

Utilizing 50CrMoA precision-forged alloy steel produced by Zhongyuan Special Steel, China's top steel mill, to ensure the substrate's strength, wear resistance, and thermal stability. Shell thickness ≥75mm.
02

High-Precision Welding Process

Axle head and shell are interference fit welded and then stress-relieved by tempering; ensuring the product has a simple structure, positive centering, strong load-bearing/impact resistance, and low deformation.
03

Composite Heat Treatment Process

Employing a combination of nitriding, quenching, tempering, and deep cryogenic treatment (-190°C); surface hardness HRC≥60.
04

High-Hardness Wear-Resistant Coating

Using American-imported Praxair JP8000 supersonic flame spray equipment with tungsten carbide powder; coating uniformity deviation <±0.01mm, hardness increased to HV1200~1500.
05

Independently Developed Peripheral Heating Corrugating Rolls

With years of independent research and development in peripheral heating pore technology, it has been successfully applied to many internationally renowned brands and domestic corrugating equipment; 40% of the company's orders are derived from this technology, which has proven to be market-proven and reliable.
06

Flute Profile Optimization Design

With two decades of professional experience and computer-aided optimization design, it reduces paper take-up rate (under the same tooth number/flute height), enhances the physical properties of cardboard, and helps customers save on raw paper costs; industry with significant technical barriers.

Why Choose Us
EXPLORE OUR FEATURED
Excellent product with exquisite craftsmanship
  • High-quality Roll Material and High-speed Production

    We use premium-grade 50CrMoA roll material, supporting high-speed production.Our corrugating roll operating speed can exceed 350 m/min.

  • Corrugation Pattern Design Experience

    With over 20 years of experience in corrugation pattern design, our designed corrugating rolls have the same flute height and pitch as others, but with a material consumption rate that is 1%-0.5% lower than the industry standard.This does not compromise the physical properties of the corrugated cardboard, helping customers save on raw paper costs.

  • Exclusive Composite Heat Treatment Process

    Our exclusive composite heat treatment process includes surface processing, compound nitriding, tempering, deep cryogenic treatment, and other multi-step processes to maximize surface hardness. The microstructure after heat treatment is more refined, with hardness reaching HRC ≥60. The service life is exceptionally long; the peripheral heating corrugating rolls have a lifespan exceeding 100 million meters.

  • Ultrasonic Tungsten Carbide Spraying Equipment and Powder

    We use the ultra-high-speed tungsten carbide spraying equipment and Praxair 1342 ultra-hard tungsten carbide powder from Praxair USA. This significantly reduces porosity and corrosion. We use high-precision Siemens CNC grinding machines to ensure the high precision of the corrugating rolls.

  • Special Polishing Technology

    Our unique polishing technology achieves a surface roughness of Ra0.2-0.4. A silicon oil coating is applied to the surface to effectively prevent pitting corrosion and rust.

  • Full-Process Manufacturing and Strict Quality Control

    We have full-process manufacturing capabilities and follow strict manufacturing and quality inspection procedures. This guarantees delivery of our products.
