Texture decoration is an important factor to improve the appearance quality of home appliances. Making different shapes and forms on the surface of metal appearance parts can play a decorative role on the surface of home appliances. The appearance texture decoration technology of metal products is varied. Today, let’s take a detailed inventory of several major technologies to realize the surface texture decoration of metal products. Let’s see how much you know?
1. Metal etching
Metal etching is also called photochemical etching. It removes the protective film on the pattern area to be etched after exposure to plate making and development, and contacts chemical solution during metal etching to achieve the effect of dissolution and corrosion, forming concave-convex or hollow molding effect. For general consumer products, patterns or text LOGOs on aluminum plates are often made by etching. In addition, etching is also often used to make various metal speaker meshes.
2. CNC machining
CNC machining refers to machining with CNC machining tools. CNC machine tools are programmed by CNC machining language to control the feed rate and spindle speed of the machining tool, as well as tool changers, coolants, etc., to physically process the surface of the substrate. CNC machining has great advantages over manual machining. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be completed by manual machining.
3. Metal coating
Metal coating usually refers to a product formed by coating or bonding a plastic film after surface treatment of a steel substrate and baking it. Metal lamination product is to compound PVC film on the metal surface to make it firmly combined, also known as PET/PVC film color steel plate. The product has the advantages of beautiful appearance, excellent processing performance, corrosion resistance and scratch resistance, and can achieve different effects from low light to high light. The film material on the surface has the characteristics of special treatment such as printability, and can show a variety of color and texture effects.
4. Pre-coating process
Pre-coated sheet is to pre-coat the metal plate, that is, to spray paint on the metal surface. In addition to the decorative effects of monochrome, pearlescent, pattern, etc., the application field of pre-coated sheet has also expanded from the original blinds to building exterior walls and interiors. Decoration, transportation and home appliance exterior and other industries.
