Metal Replacement Rollers

The aluminum guide roller has the advantages of high unit strength, light weight, small inertia, bright surface and no rust, and is widely used in embossing printing, coating, coating, blown film, lamination, coating, slitting, paper making, textile, etc. production line. The production of aluminum alloy guide rolls has passed the most stringent raw material extrusion production process. The high-strength special section and ribs can greatly enhance the rigidity of the aluminum tube. The excellent hot assembly process and the surface finishing of the CNC lathe can achieve the highest combination of products. Strength and precision, good linearity and concentricity, precise high-speed dynamic balance system can ensure static balance and high-speed dynamic balance performance (up to ISO1940 G1 grade), ensuring that aluminum rollers run at high speed on the machine without vibration, but different The surface treatment provides different application requirements, and the new aluminum rollers can greatly improve the performance of your machine.
The structure of the aluminum guide roller can be roughly divided into:
(1) Hollow aluminum roller: The inner bearing type structure, the bearing is assembled in the inner bearing hole at both ends.
(2) Coaxial aluminum roller: The steel body or stainless steel shaft end is combined at both ends of the roller body, which is an integrated structure.
(3) Water-passing aluminum roller: cooling or heating liquid enters and exits through both sides and circulates in the roller body.
(4) Special rollers: various special structural rollers processed according to the drawings.

Different surface processing methods for aluminum guide rolls:
(1) Glossy surface: surface with smooth and low resistance, which can reach different surface roughness Ra0.3~Ra6.3 according to requirements
(2) Surface thread: Commonly used cross thread and center unfolding line (two points from the center, extending to both ends).
(3) Concave and convex surface: Various concave, convex and arc-shaped surfaces can be processed by CNC lathe.
(4) Sand blasting or shot peening: sand blasting or shot peening can obtain a rough surface and increase friction.
(5) Knurling or network cable: Different sizes of flower surface can be provided according to customer requirements.

Different surface treatments or coatings for aluminum guide rolls.

(1) Universal white oxidized surface: moderate surface hardness HV300, low cost, can also provide different color surface (such as pure black) according to customer requirements, suitable for low tension film industry.

(2) Brown hard oxidized surface: high surface hardness HV700 and 0.1mm or more oxide film thickness, Taiwan introduced oxidation technology, high hardness and high abrasion resistance can be applied to various high tension and thick materials, which can be greatly improved The life of the aluminum roller.

(C) Teflon surface: The special Teflon coating makes the ink easy to clean and provides moderate anti-stick properties.

(4) Rubber surface: The aluminum roller is used as the core shaft, and different rubberized layers can provide versatility of different characteristics and different hardnesses.

(5) Industrial hard chrome surface: higher surface hardness and corrosion resistance, surface roughness can be as low as Ra0.01 (ultra-mirror surface), compared with traditional chrome-plated steel rolls.
