Decorative aluminum profiles for wire-drawing can eliminate scratches, scrapes and machining knife marks on the surface. The degree of elimination is related to the depth of the wire drawing, the greater the depth of the wire drawing, the stronger the ability to eliminate decorative aluminum profiles surface texture defects.
However, demanding wire drawing treatment needs to use polishing or polishing and other pretreatment before wire drawing to eliminate the surface defects of the workpiece, especially for shallow wire drawing should be so. In addition to the decorative aluminum profiles mentioned above which can eliminate surface defects, the more important role of wire drawing is to improve the texture of metal materials to provide a strong decorative effect to increase the appearance of products, which is also a commonly used decorative method.
Decorative aluminum profiles surface drawing is done by wire drawing machine, small flat workpiece can be used flat press belt drawing machine, this drawing way is based on the surface requirements of the product is different, you can choose coarse-grained belt processing rough, have obvious feel silk, you can also choose fine grain sand belt processing more delicate silk. For small workpiece can also use a more simple structure of the erasing machine to carry out, the thickness of the silk can also be controlled according to the thickness of the grinding block particle size. For large workpiece or plate can also use roller brush drawing or wide sand belt drawing, etc.
Refer to the operation manual of wire drawing equipment for the specific operation method of wire drawing.
Sandblasting or wire drawing provides decoration at the same time also has the function of covering decorative aluminum profiles surface defects, wire drawing is easier than sandblasting to cover decorative aluminum profiles surface defects, For the depth of the larger thread even allow the workpiece surface has more obvious scratches, scrapes and other machining marks. Sandblasting can only cover up minor scratches, bruises, etc., for the workpiece with obvious machining marks, it should be polished or polished in advance before sandblasting.
