Detailed Product Description
Catagory:
1,HV300 aluminum roller
2,HV700 aluminum roller
3,Teflon aluminum roller
4,Mirror-Surface Roller
Introduction:
Aluminum roll uses high quality domestic and imported steel, aluminum tube, 20# steel, 45# steel, forged alloy steel (42GrMo, 38GrMoAI),
work by advanced heat treatment quenching, to stress,hardening,
and inner hole machining,after that thickness will be uniform,surface hardness can up to HRC50 ~ 62 after quenching.
Different surface treatment & coating on aluminum roller:
1:Generic white oxide surface:Moderate surface hardness HV300, lower cost, but also available upon request different color surfaces (such as pure black), suitable for low tension film industry.
2:Brown hard anodized surface: The height and thickness of oxidized surface hardness HV700 over than 0.1mm,Taiwan imported oxidation technology,high hardness and high wear resistance can be applied to a variety of high tension and thicker material, can significantly improve the aluminum roll life.
3:Industrial hard chrome surface: The highest surface hardness and corrosion resistance, surface roughness can be as low as Ra0.01 (super mirror), due to lighter weight than steel rolls,
chrome-plated aluminum roll is suitable for higher-speed machines.
4:Rubber surface: Aluminum roll as the mandrel, different layer can provide different packages with different characteristics and hardness.
5:Teflon Surface: Special Teflon coating layer allows easy cleaning of ink, and provides moderate anti-adhesive.
Different surface processing methods:
1:Smooth: has a smooth, low surface resistance, to follow the requirements to achieve different surface roughness Ra0.3 ~ Ra6.3
2:Screwing line surface: common cross threads, the center expanded line (extending from the center to the ends of the surface dichotomy).
3:Concave & convex surface: CNC lathe can be processed into a variety of concave, convex type and circular type surfaces.
4:Grit or shot blasting surface: Sand blasting or shot blast process may obtain the rough surface can increase friction.
5:Knurled or network cable surface: According to customer requirements to provide a pattern surface and different sizes.
