1. Operational process of wire drawing
Wire drawing aims to form a continuous silk texture on the surface of Stainless steel sign to enhance its beauty and texture. First, make sure the surface of Stainless steel sign is clean and flat, and remove impurities such as oil, rust, etc. Then, prepare the wire drawing tools according to the requirements of the wire drawing direction (such as horizontal, vertical or oblique). For small batch production or small-sized signs, manual wire drawing cloth wheels can be used, while large-scale production mostly uses automatic wire drawing machines. During operation, the wire drawing tool is closely contacted with the surface of the sign, and the wire drawing tool is pulled or moved at a uniform speed in the predetermined direction. For example, if a manual wire drawing cloth wheel is used, the operator needs to apply uniform pressure to ensure that the depth of the drawn silk texture is consistent. During the wire drawing process, the effect of the silk texture should be checked frequently to ensure that the texture is uniform and coherent, without interruption or disorder.
2. Basic operation of polishing
Polishing is to make the surface of Stainless steel sign as bright as a mirror. Before starting polishing, the Stainless steel sign needs to be pre-treated, such as grinding off the rough part of the surface. Polishing is usually done with the help of a polishing machine and polishing paste. Apply an appropriate amount of polishing paste to the polishing wheel of the polishing machine, start the polishing machine, and make the polishing wheel reach the appropriate speed. Next, gently move the Stainless steel sign against the polishing wheel, paying attention to controlling the pressure to avoid excessive pressure causing surface deformation. When polishing, ensure that all parts of the sign surface can be evenly contacted with the polishing wheel, which can be achieved by slowly moving the sign. If it is a sign with a complex shape, it may be necessary to use polishing wheels of different shapes and sizes, or manually assist in polishing some difficult-to-polish parts until the entire sign surface presents a uniform bright effect.
3. Combination of wire drawing and polishing
Some Stainless steel signs may need to be wire drawn first and then polished to achieve a unique visual effect. First, follow the wire drawing process to draw out the required silk pattern. Then, perform partial or full polishing on the basis of wire drawing. For example, for some areas where the content of the logo needs to be highlighted, selective polishing can be performed after wire drawing to make the logo more eye-catching. In this combined operation, special attention should be paid to the treatment of the transition area between wire drawing and polishing to ensure that the transition is natural and there are no obvious marks. During operation, the scope and degree of polishing need to be precisely controlled, so as not to damage the wire drawing effect and achieve the expected polishing purpose.
4. Quality control and precautions
Quality control is crucial when performing surface treatment of Stainless steel sign. For wire drawing treatment, check the uniformity, depth and direction of the wire pattern. For polishing treatment, pay attention to the brightness of the surface and whether there are polishing marks. Safety should also be paid attention to during operation, such as preventing the polishing wheel from flying out and injuring people when using a polishing machine. At the same time, it is necessary to select appropriate wire drawing cloth wheels, polishing pastes and other materials according to the material characteristics of stainless steel, and pay attention to the influence of ambient temperature and humidity on the surface treatment effect to ensure that the surface treatment effect of the final produced Stainless steel sign meets the design requirements.
