Industry metal products industry also encountered some difficulties in the development process, such as single technology, low technical level, lack of equipment, shortage of talents, etc, this has restricted the development of the metal products industry. To this end, we can improve the development of the metal products industry by improving the technical level of enterprises, introducing technical equipment, and cultivating suitable talents. In 2009, products in the metal products industry will tend to be more and more diversified, the technical level of the industry will be higher and higher, the product quality will be steadily improved, and the competition and market will be further rationalized. Hardware products auxiliary and accessory finished products used in daily life and industrial production.
Shantou nickel label electroforming factory punching: using special tools to punch and cut a certain shape on the metal sheet can be applied in batch production. Punching: it is basically similar to the punching process. The difference is that the former uses the punching part, while the latter uses the rest of the metal sheet after punching. Shearing: cutting metal sheets by shearing is the same as cutting paper from the position by a pair of scissors. Chip Forming: when cutting metal, the cutting method of chip production is collectively referred to as chip forming, including milling, drilling, lathe processing, grinding, sawing and other processes.
chemical stability of the material itself: stainless steel has the properties of high temperature resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, etc. Affected by the chemical structure of stainless steel, in harsh environment, such as: high temperature, wet and cold, long-term exposure to rain medium environment, stainless steel signs can still maintain bright and bright for a long time, no deformation. In short, it is characterized by strong annual use and not easy to deform. In the choice of making metal signs, stainless steel and aluminum are very common metal materials, so what is the difference between the advantages and disadvantages of these two materials?
comparison of advantages and disadvantages between the two: stainless steel plate has stable structure, firmness and durability, and is not easy to deform; Stainless steel has strong corrosion resistance, acid and alkali resistance and oxidation resistance, and is not easy to rust. Aluminum plate is light in weight, unstable in structure, easy to deform and rust, poor in oxidation resistance and easy to corrode. The stainless steel material has a strong three-dimensional effect, and the surface style looks more upscale and is often used for high value-added commodity decoration.
there are not many small nameplates made of aluminum, because the logo nameplates and other products made of aluminum are not as delicate as stainless steel, and the gloss is relatively poor, moreover, the surface of the aluminum sign is easily scratched and ground. Stainless steel sign stainless steel sign stainless steel sign its material is 304 stainless steel, has good resistance to atmospheric and freshwater medium corrosion performance, and through corrosion, polishing, drawing after the decorative effect is very high-grade and beautiful. Stainless steel signs are generally divided into concave signs, convex signs and concave-convex signs.

Under the action of electrolysis, a metal electroforming layer is gradually deposited on the surface of the original mold, and the metal electroforming layer is taken out of the solution after reaching the required thickness, and the electroforming layer is separated from the original mold, the metal parts corresponding to the shape of the original mold are obtained. The stability of nickel plating layer in air is very high. Due to the strong passivation ability of metal nickel, a very thin passivation film can be rapidly formed on the surface to resist the corrosion of atmosphere, alkali and some acids.
The operator lays the electroformed stainless steel on the working table, and cuts the OPP protective film with appropriate size to the surface. Light fold (Bending) Stainless steel plate to separate electroformed products from stainless steel. The glue brushing operator takes an 80-mesh clean screen and places it on the printing machine, and debugs it. Seal the position that does not need printing with gummed paper.
The ultra-thin nickel label made of Hot Melt Adhesive is pasted on the leather. If the ultra-thin nickel label is to be pasted on the leather, such as mobile phone holster, leather Bluetooth speaker on the surface, etc. The label with ordinary water glue is pasted on the leather material and will fall off easily, which requires the use of hot melt glue when selecting glue. Hot Melt Adhesive has high temperature resistance of 50℃ and low temperature resistance-40 ° C.
plastic spraying is a surface treatment method for spraying plastic powder on parts. The treatment process is a relatively common decoration technology for metal surface treatment in the world. L cast iron and cast aluminum cast iron are the general name of alloys synthesized by iron, carbon and silicon. Cast Aluminum is a process in which molten aluminum is poured into a mold and cooled to form aluminum parts of the required shape.
