Jwell Hot Mill Roller for Plastic Sheet and Nonwoven Lamination
High-strength hot mill roller with HRC58–62 surface hardness and efficient hot-oil circulation for plastic sheet forming, nonwoven thermal lamination, polishing and embossing.
Roller Features
- HRC58–62 Surface Hardness — Heat-treated alloy-steel construction for demanding service.
- High Strength, Low Deformation — Supports uniform product thickness under pressure.
- Uniform Heat Transfer — Helps maintain a stable roller-surface temperature.
- Two Hot-Oil Channel Designs — Spiral inner liner or circumferential drilled channels.
- Multiple Processing Uses — For plastic sheet, nonwoven fabric and leather applications.
Product Description
The hot mill roller is designed for forming high-density plastic plate and sheet and for thermal lamination of nonwoven materials. Its special structural design provides the strength, toughness and heat resistance required for applications where the roller must operate under pressure while maintaining stable surface temperature. It is also suitable for surface polishing and embossing of thin PC and PMMA sheet, nonwoven fabric and leather.
The roller body can be manufactured from high-quality alloy steels including 38CrMoAlA, 42CrMo, 60CrMoV and 9Cr2Mo. After machining and heat treatment, the roller surface hardness can reach HRC58–62. This construction supports high overall rigidity and helps limit roller deformation under compressive loads, contributing to more uniform finished-product thickness.
Two internal hot-oil circulation structures are available: a spiral inner-liner channel and circumferential drilled channels around the roller body. The guided hot-oil flow improves thermal exchange and helps reduce the temperature difference between the two ends of the working surface. More uniform heat distribution supports stable forming, laminating, polishing and embossing performance across the usable roller width.
For technical selection, buyers should provide the required roller diameter and face length, product material, operating temperature, line speed, pressure or load conditions, surface-finish requirement and preferred heat-transfer-oil connection. JWELL can then evaluate the appropriate alloy-steel grade, internal circulation structure and roller configuration for the intended plastic-sheet or nonwoven processing line.
