Aluminum Foil Roller

Brief introduction of the structure of aluminum guide roller

From the surface structure of the aluminum guide roll body, it mainly consists of two parts: the mesh and the mesh wall; from the composition structure, it is mainly composed of the roll core, the base material and the surface plating. The commonly used material for the base material is electroplated copper, which is the basis for making the mesh and the mesh wall; the surface plating is made of metal chromium or ceramic, which mainly improves the wear resistance and the corrosion of the solvent to the base copper layer.

Heating aluminum guide roller
It can directly process various lines and embossed patterns on the aluminum guide roll surface, without special pre-plated copper wall for the roll surface, long service life and uniform pattern, suitable for compound sizing, coating and ink transfer. , glazing, etc. Mainly used for sizing and coloring. Suitable for plastics, leather, leather, paper, carton machinery and other industries.

The as-cast microstructure of the mirror roll is austenite and a small amount of martensite. The carbide is mainly M7C3 type, and the shape is granular, massive, strip-shaped, and the distribution is relatively uniform, and it is not mesh-like. This kind of tissue has a macro hardness of HRC45-50, which has high impact toughness. Microhardness carbide (M7C3) HM1 422 - 1 813, matrix HM426 - 467.

Different surface processing methods of aluminum rollers:

(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: The concave, convex and arc-shaped surfaces can be machined 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.
