A magnet will not attract the tungsten carbide coating itself. However, whether a magnet can attract the entire "tungsten carbide coated roller" depends on whether the roller substrate is magnetic. For example: • If the substrate is carbon steel → magnetic → a magnet can attract it.

According to data from Jinhang Machinery, the dielectric strengths of different coatings are approximately as follows: • Silicone corona roller: Approximately 400 inches/kW • Epoxy-coated corona roller: Approximately 500 inches/kW • Ceramic corona roller: Approximately 300 inches/kW

As one of China's leading high-quality industrial roller manufacturers, Jinhang Machinery possesses mature capabilities in designing and manufacturing various high-precision rollers. We can tailor rollers with various structures, sizes, and special functions to meet specific customer needs.

Jinhang Machinery, a professional roller manufacturer in China, not only manufactures various industrial rollers but also provides customized processing, deep processing, precision polishing, plating, hard chrome plating, and tungsten carbide spraying processes based on customer drawings, achieving perfect processing of mirror

Machining is a crucial stage in mirror roller manufacturing, mainly involving rough machining, semi-finishing, and finishing. For high-precision mirror rollers, the permissible error is typically within the range of 0.01–0.03 mm.

Almost all industries that require material softening, plasticizing, coating, pressing, stretching, or shaping require heated rollers. In short, wherever a production line uses heat to influence material properties, heated rollers play a crucial role.

NBR rollers can withstand temperatures of approximately 120°C in air and approximately 150°C in oil. This is determined by the combined characteristics of NBR's molecular structure, heat resistance, and oil resistance.

Hot water typically heats up faster in the low-temperature range (≤150℃). • Hot water heating roller → The medium transfers heat to the roller body more quickly → The roller body heats up faster. • Oil-guided heating roller → Heat transfer is slower → The heating rate is naturally slower.

Due to their performance characteristics, EPDM rubber rollers play a crucial role in many fields such as printing, papermaking, textiles, plastics processing, chemicals, food processing, and metal handling. Jinhang manufactures and processes various high-precision industrial rollers, including but not limited to rubber rollers.

The machining parameters of Jinhang, a high-quality industrial roller manufacturer in China, are as follows: • Maximum machined outer diameter: 2000 mm • Maximum machined length: 8000 mm • Maximum mirror roller surface roughness: RA 0.005 μm • Maximum overall accuracy (coaxiality / circular runout): 0.002 mm

The fastest cooling speed generally refers to: Cooling rollers with a bidirectional spiral flow channel + thin-walled structure + high thermal conductivity material + mirror finish + low-temperature chilled water medium.

As a professional roller manufacturer, Jinhang Machinery possesses a complete high-precision machining system. Its equipment configuration is a crucial foundation for becoming an excellent roller manufacturer.
