Zhuhai metal hollow plate

sand mold casting: low cost, small batch, can process complex shapes, but may require a large number of post-processing procedures. Investment casting/lost wax casting: this processing method has high continuity and degree, and metal products can also be used to process complex shapes. On the premise of relatively low processing cost, it can achieve perfect surface effect and is suitable for mass production. However, the metal ions in the metal salt lose electrons and become positive metal ions, gradually move and deposit on the original mode of the cathode, and form an appropriate thickness (Thin Standard thin can reach 0. 04mm). The application range of nickel sheet label products is very wide. The thickness of nickel sheet thin label can be controlled at 0 on products such as mobile phone case, protective cover, electronic digital product case, home appliance product case, gift box outer package, etc. 05-0. Within the range of, the surface can be used for wire drawing, netting, vacuum plating and oil injection.

For example, 6W6Mo5Cr4V2, the specific heat treatment process is quenching heating temperature 1160-1180 ℃, after cooling, after 550- Tempering at 570 ℃ for three times, hardness Rc60- 63, used for cold extrusion punch or cold heading punch can double the service life. Matrix Steel: Matrix Steel is another way to improve the toughness of high speed steel. Compared with high speed steel, Matrix Steel has few excess carbides and fine carbide particles, the distribution is uniform, so the impact toughness and fatigue strength are better than that of high speed steel, while maintaining good wear resistance. Matrix Steel successfully developed and popularized in China.

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.

technological process of making nickel sheet label II. Cleaning steel plate and steel plate is the carrier when making nickel label, and the steel plate can be recycled, A plate can be repeatedly plated 2000 times, and each time it is reused, it must be cleaned and polished. Operation Guidance: The operator turns on the switch of the grinding machine and holds the stainless steel plate with both hands to make it close to the nylon wheel; Move left and right up and down, polish the stainless steel to make it bright and flat, and visually check the surface for nickel spots, letter marks and scraping. Polished stainless steel is placed in clear water to avoid oxidation of stainless steel plates.

clear water after OK, and wait for full inspection after drying. The pickup operator removes the excess waste from the electroformed stainless steel surface, puts the steel plate in the material rack, and dips the material rack into the deinking tank. The temperature in the tank is kept at 45 ℃ ~ 60 ℃, soaking time 10 ~ 15 minutes. After OK, take it out and rinse the ink on the surface of the steel plate with clear water.

in some electronic products, large machinery, customers like to use stainless steel signs. Based on the use environment of stainless steel signs, customers are generally recommended to choose water glue. Water Gel high temperature resistance 80 ° C, low temperature resistance- At 40 ℃, the label can be directly placed in the reserved position in the product during operation. Other frequently used glues include adhesive, Sun glue, etc. Engineers will choose the appropriate glue according to the customer's use environment for the label. No matter what kind of glue, we will try our best to meet the needs of customers and provide them with quality brand services.
