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.
Corona roller
Silicone corona rollers, ceramic corona rollers, and epoxy-coated corona rollers
Structure: Supports a variety of special roller surface treatments, such as silicone coating, ceramic coating, and epoxy spraying.
Processing Dimensions and Precision:
Applications:
Surface treatment of plastic films, metal films, and plastic sheet products
Product Description:
Supports a variety of custom coatings. The service life and performance of different coatings are as follows.
Silicone corona rollers: Dielectric strength is approximately 400 in²/kW. However, for rollers with larger diameters, vulcanized silicone is recommended. Silicone is very economical and can be replaced, but its service life is only about six months.
Epoxy-coated corona rollers: Dielectric strength is approximately 500 in²/kW. Epoxy-coated corona rollers are more durable than silicone corona rollers, with a service life of about one year. Epoxy resin coating is also available. The epoxy resin value varies depending on the operating temperature and hardness requirements. When choosing epoxy resin, please inform us of the operating temperature and required hardness of the roller. Pinholes on the epoxy resin corona roller surface can be repaired on-site.
Ceramic corona rollers: Dielectric strength is 300 in²/kW. They have a service life of approximately two years and offer resistance to high-temperature oxidation, heat insulation, wear, and corrosion. While the manufacturing cost of ceramic corona rollers is higher than silicone and epoxy corona rollers, they can withstand more extreme operating environments.
Custom Roller Design and Processing
We design roller processing drawings based on your equipment requirements, including roller material selection, roller welding requirements, roller precision, special surface treatment, and optimized roller structure.
