Zhuhai self-adhesive nickel standard

during the 12th Five-Year Plan period, China will change the development mode of hardware industry, on the premise of saving resources, reducing consumption, protecting the environment and improving the quality and efficiency of economic growth, we will continue to maintain an orderly, healthy and rapid growth of the industry, strive to transform China from a hardware manufacturing power to a hardware manufacturing power. In the early days, it was made of metal materials such as gold, silver, copper, iron and tin, hence its name.

Zhuhai self-adhesive nickel standard

Zhuhai self-adhesive nickel standard, sand mold casting: low cost, small batch, can process complex shapes, however, a large number of post-processing procedures may be required. 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.

metal particles are sintered and formed by high temperature heating. This process does not require machine processing, and the utilization rate of raw materials can reach 97%. Different metal powders can be used to fill different parts of the mold. Solid molding solid molding processing: refers to the raw materials used are some metal strips, sheets and other solid forms that can be molded at normal temperature.

metal flat signs are usually made by screen printing or color printing technology. Metal signs made by printing technology are very high-grade with bright colors, however, there is also a disadvantage that the paint on the metal surface falls off due to external scraping during installation or transportation. Therefore, in this context, sign makers use a layer of film on the metal labelto protect the paint on the surface of the metal sign, remove the film when ensuring that the metal plate is 'safe. Metal flat signs are usually made by screen printing or color printing technology, and the metal signs made by printing technology are very colorful and high-grade, however, there is also a disadvantage that the paint on the metal surface falls off due to external scraping during installation or transportation.

high wear-resistant micro-deformation cold deformation die steel is represented by Cr12Mov type, which is a high-performance cold deformation die steel widely used abroad. Cr12Mov is an improved Cr12 steel. The carbon content is too high, resulting in serious uneven large bulk carbides. Cr12Mov steel is characterized by high wear resistance and hardenability. It is a micro-deformation cold blanking die. The main material of cold heading die is still widely used in general factories. The modified material has high hardness and high wear resistance, high hardenability, especially small deformation after heat treatment, good filing performance during pliers processing, is still widely used in blanking forming dies, drawing dies and other dies.

W18Cr4V (1220 ℃-Heating and quenching at 1250 ℃), W6Mo5Cr4V2 (Use 1170 ℃-1190 ° C) The mould treated by low temperature heating and quenching has high plastic deformation resistance, high hardness and wear resistance; There is enough blade property. Practice has proved that the punch quenched at low temperature can significantly prolong the service life and greatly reduce the fracture accident of the punch. Ductile cold deformation die steel some cold extrusion dies and cold heading Dies need to bear high strength and high impact toughness, while ordinary high speed steel and high carbon chromium rigid parts are easy to brittle break or break, and the dies need to have high strength and toughness, it can be divided into two categories: Carbon High speed steel: W series or Mo series high speed steel with carbon content reduced to 0. 5-0. 6%, increase the toughness of the treated steel.
