Introduction of surface drawing process for aluminum profiles

Update time : 2022-08-17 18:24:21

Drawing can eliminate the scratch, scratch, machining tool marks of aluminum alloy profiles. The degree of elimination is related to the depth of the wire drawing. Generally speaking, the greater the depth of the wire drawing, the stronger the ability to eliminate the material defects on the surface of aluminum alloy. However, for the demanding wire drawing treatment, it is necessary to use polishing or polishing pretreatment to eliminate the surface defects of the workpiece before drawing, especially for the shallow wire. In addition to the above mentioned can eliminate the surface defects of aluminum alloy workpiece, a more important role is that the drawing can improve the texture of metal materials, provide a strong decorative effect to increase the appearance of the product, which is also a commonly used decorative method. In recent years, drawing is widely used in the shell decoration of a variety of electronic products, such as the panel of laptop computers, keyboards, mobile phone panels and other digital products related parts.

Wire drawing machine wire drawing is adopted to the surface of the aluminum alloy, can be used for small plane workpiece flat pressure type abrasive belt wire drawing machine, this way of drawing according to the requirements of the product surface is different, can choose a coarse-grained abrasive belt and processing the rough, there is a clear feel silking, also can choose fine-grained sand belt work out more exquisite and silking. For small workpiece can also be used a more simple structure of the rubbing machine to carry out, the thickness of the wire can also be controlled according to the grain size of the grinding block. For large workpiece or plate can also be used roller brush drawing or wide sand belt drawing.

Sandblasting or wire drawing in providing decoration at the same time have played the function of covering the surface defects of aluminum alloy workpiece, for sandblasting and wire drawing, wire drawing is easier to cover the surface defects of aluminum alloy workpiece, for larger depth of wire drawing and even allow the surface of the workpiece to have more obvious scratches, scratches and other mechanical processing traces. And sandblasting is only allowed to have a slight scratch, abrasion, etc., for mechanical processing traces obvious workpiece should be pre-polished or polished after sandblasting treatment.
