Shenzhen metal brushed copybook-Metal signage manufacturer

Shenzhen metal wire drawing copybook

has entered many industries in the 1980s s, especially the automobile industry, which relies more on powder metallurgy technology than ever before, using as many high-performance parts of powder metallurgy as possible is a powerful means to improve the competitiveness of automobiles, especially cars, in the market. High density P/M products are the key factors to ensure their excellent mechanical properties. Therefore, in order to expand the application range of powder metallurgy P/M Parts, it is necessary to increase its density to obtain powder metallurgy parts with excellent mechanical properties. Generally, the whole surface is used as a sign.

This type of sign is characterized by waterproof, low price and mass production. It can be directly pasted with neutral glass glue and paint surface. The disadvantage is that the appearance is not as delicate as metal signs. Aluminum Alloy sign aluminum alloy sign is a popular material in 1990s, aluminum. Compared with traditional materials, it does not rust, has light volume and low cost. The big signs we usually see outside, the signs are all made of aluminum alloy, such as the signs on the road, and some cards are also made of aluminum alloy.

Shenzhen metal wire drawing copybook, SiMnMo series Graphite Steel, is characterized by high Si content. Under the strong action of graphitization element Si, part of carbon exists in graphitization state, which makes steel have self-lubricating effect, high bite resistance, good machinability and wear resistance, small heat treatment deformation and stable size. SiMnMo steel is used to make bending, stretching and punching dies with strict surface quality requirements, which can significantly improve the quality of punching parts.

Shenzhen metal wire drawing copybook, such as 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.

nickel sheet label manufacturing process; Photosensitive development photosensitive: The operator first checks whether the film has yarn eyes and scratches, and the yarn eyes are in diameter of 0. Below 5MM and the scraping diameter is 0. Less than 2MM can be repaired with a black pen, and too large yarn holes and scratches are directly scrapped; Check the exposure machine glass for black spots and dust, and if any, clean it.

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.
