Founded in 2001, Jiangsu Jinhang Machinery Manufacturing Co., Ltd. has obtained the ISO9001 Quality Management System Certification. We are committed to the R&D and manufacturing of various roll types with different roll body structures. In accordance with the requirements of mechanical equipment, we can design rolls that meet the application needs. Meanwhile, we also provide custom processing services, enabling us to carry out custom manufacturing based on your drawings.
The goal of Jinhang Machinery is to design and manufacture efficient, stable and durable rolls within a reasonable budget. Each roll undergoes quality tracking and inspection at different process stages, and only after passing the inspection can it proceed to the next process, ensuring that all rolls meet the quality requirements before leaving the factory. We also provide reliable and practical after-sales services. Within the warranty period, for any quality issues that occur under the mechanical conditions specified in the drawings, we will provide free repair or replacement of the rolls.
Currently, the company has a standard workshop covering an area of 13,000 square meters and a team of over 60 employees. Our equipment lineup includes CW61190, 61160, 61120, 61125 and 6180 lathes, imported Italian POMINI universal grinding machines, 1380, 1363 and 1350 grinding machines, 160 and 110 boring and milling machines, vertical milling machines, drilling machines, dynamic balancing machines, plate bending machines, automatic welding machines, as well as domestically advanced polyurethane casting machines and fully automatic environmental protection sandblasters.
We specialize in manufacturing and processing various high-precision rolls with strict requirements, including various rubber rolls, polyurethane rolls, heating rolls, mirror surface rolls, chill rolls, corona rolls, ceramic anilox rolls, chrome-plated rolls, tungsten carbide rolls, and other various customized carbide-coated rolls and special roll shapes. Our products are widely applicable to industries such as metallurgy, mineral processing, packaging, printing, lithium battery manufacturing, and automotive testing equipment.

Product Description:
Tungsten carbide has advantages such as high melting point, high hardness, poor electrical and thermal conductivity, and stable chemical properties, making it an ideal material for producing wear-resistant and corrosion-resistant coatings. However, due to its high melting point and high hardness, sprayed tungsten carbide particles have poor adhesion to the substrate and are prone to oxidation when exposed to elevated temperatures in air. Therefore, pure tungsten carbide powder is rarely used alone as a thermal spray powder material. It is typically added with metals or alloys such as Co, Ni, or Ni-Cr as a binder phase to create sintered or coated powders for thermal spraying. Tungsten carbide, cobalt and tungsten carbide series thermal spray powders have been widely used. Because the coatings prepared by them have extremely high hardness, excellent wear and corrosion resistance and good toughness, they are widely used in aerospace, automobile, metallurgy, electric power, papermaking and other fields to improve the wear resistance of component surfaces and repair worn areas.
