The production process of stainless steel signs you don't know1

There are many kinds of materials for signs, among which stainless steel signs are a large category. Stainless steel is a special material, which has good resistance to atmospheric and freshwater medium corrosion. Therefore, its manufacturing process is much more difficult than that of copper plate and aluminum plate. However, the decorative effect obtained after corrosion, polishing and wire drawing is very beautiful, so the fastest corrosion method for stainless steel is electrochemical corrosion, also known as electrolytic corrosion. Because electrochemical corrosion will cause ink to fall off during sign corrosion, sign is not suitable for electrochemical corrosion, especially fine patterns. The following is the manufacturing process of stainless steel signs. 1. Use a computer to arrange the graphic files of the signs, and then use a lettering machine to engrave the layout of the signs with stickers; 2. The engraved self-adhesive is accurately attached to the plate to make the film stick flat and firmly attached. It is necessary to heat the plate with the film attached; 3. Wear heat-insulating gloves and heat the label to a hot point on the honeycomb briquette stove (About 90-100 degrees Celsius, estimated) , Then remove the text, lace, form a hollow version; 4. Use pickling or sand to deal with the label so that the paint can be firmly combined with the plate; 5. Clean and corrode the signs and prepare for painting. Paint can be painted (Must have an oven)Or car metal paint can be; 6. After the paint is sprayed and dried, remove the excess adhesive on the label, and the product is completed; 7. Final defect treatment: if the label is left on the label due to self-adhesive degumming, it can be removed with a rag and some loose Perfume. The above is the manufacturing process of the stainless steel label, but there are still things to pay attention, first of all, the self-adhesive should be of good quality, so that it can be firmly pasted on the stainless steel plate, and it is not easy to degumming after baking. If the paint is removed at some position, the sticker of the part can be engraved, and the sticker is placed in the defective position. After the paint is repaired with a small brush, the sticker is removed immediately. It can be repaired.
