• Relatively simple industrial rollers: Generally require 3–5 weeks • Customized industrial rollers of moderate complexity: Typically require 5–8 weeks • Industrial rollers with complex structures and high surface treatment requirements: Often require 8–12 weeks or longer

The rubber roller manufacturing process can be divided into the following stages: 1. Metal mandrel preparation (turning and cleaning) 2. Rubber formulation preparation and mixing 3. Rubber coating process (extrusion coating or calendering coating) 4. Vulcanization and curing (curing) 5. Precision grinding 6. Dynamic balancing 7. Surface treatment and final inspection

Insufficient dynamic balance accuracy of industrial mirror rollers will trigger a series of chain reactions; these problems are not just "possible," but "inevitable." 1. Generates periodic vibration 2. Destroys the surface finish of the mirror roller 3. Accelerates damage to bearings and transmission systems 4. Affects material surface quality

Jinhang Machinery is considered one of the leading Chinese manufacturers of high-performance ceramic corona rollers. If your production line requires a highly stable ceramic corona roller that can operate continuously in extreme environments and has a longer lifespan, then Jinhang is your choice.

Jinhang Machinery manufactures and processes a wide variety of high-precision rollers, including various rubber rollers, polyurethane rollers, heated rollers, mirror rollers, cooled rollers, corona rollers, chrome-plated rollers, tungsten carbide rollers, and other special roller types.

In the industrial field, the hardness of tungsten carbide coated rollers typically ranges from HV1100 to HV1600. These hardness parameters are far higher than those of ordinary steel rollers (HRC 30–55 ≈ HV 300–550) and significantly higher than chrome-plated surfaces (HV 800–1000).

Nitrile butadiene rubber is non-toxic, and NBR rubber rollers are also non-toxic products. Nitrile butadiene rubber (NBR) is an industrial synthetic rubber material copolymerized from acrylonitrile and butadiene, possessing excellent oil resistance, abrasion resistance, and mechanical stability.

To maintain a stable and controllable surface temperature during the processing of different materials, mirror rollers are typically designed into two types: • Heated Mirror Roller • Water-Cooled Mirror Roller

In industrial processing, the ideal state of "completely frictionless" contact between the mirror roller and the material is not ideal. On the contrary, moderate and controllable friction is often a prerequisite for stable process operation.

Plastic films (such as PE, PP, PET, PA, PVC) are most sensitive to cooling roller temperature. • PE/PP film cooling roller temperature: 20–40℃ • PET film cooling roller temperature: 10–25℃ • PA (Nylon) film cooling roller temperature: 15–30℃ • PVC film cooling roller temperature: 30–45℃

Professional roller manufacturers can not only manufacture according to drawings but also provide engineering-level design and optimization based on your equipment requirements. As a high-quality industrial roller supplier in China, Jinhang Machinery is such a roller manufacturer that can provide customized drawings and structural designs.

A mirror roller is an industrial roller that has undergone high-precision machining and polishing. Its surface has an extremely high degree of smoothness, typically reaching Ra0.01–0.02 μm or higher. Mirror rollers are used for pressing, traction, shaping, polishing, or optical-grade surface replication of materials.
