casting molding after the products need to the post-processing post-processing conditions is 60 ℃ under thermal insulation 2h 120 ℃ under thermal insulation 2 h. In addition to metal materials, non-metallic materials such as plastics and glass fibers are widely used. Hardware products have played an important role in the process of human survival and development. With the development of social economy and the refinement of social division of labor, hardware products are gradually enriched and improved, with more and more varieties. Modern hardware products can be divided into three categories according to their uses: Daily hardware for daily life, hand tools for production and living aids, building hardware as connectors, fasteners and supporting facilities in buildings and structures.
standardization factors with the continuous improvement of people's living standards, people have higher and higher requirements for visual design of signs; In the design of metal signs, it is not only required to be beautiful but also to reflect the information conveyed to people by the products of the enterprise, so that people can think of the Enterprise when they see the logo of the trademark, what kind of products are suitable for what style, what material of signs, so that people are more easy to remember; For example: Home appliances, electronic digital products, most of the choice of gold or silver logo, material selection: stainless steel or nickel material!
Hot Melt Adhesive is a kind of plastic adhesive, which has no viscosity at normal temperature. It needs to be heated to above 120 ℃ by a hot press, and only when the glue dissolves can it have viscosity, it has odorless properties and belongs to environmentally friendly chemical products. It has the characteristics of high adhesion, strong adhesion, etc. It is often used on the surface of leather goods, digital products, household appliances, etc. , like double-sided tape, and is generally attached to the overall metal label, such as stainless steel signs, electroforming thick standards, etc!
entering the 1980s s, many industries, especially the automobile industry, rely 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.

is affected by its chemical structure. Compared with aluminum, the chemical structure is stable. Under the same conditions and environment, stainless steel is not prone to oxidation, rust and deformation. Therefore, most of the users who need to keep the signs bright and beautiful for a long time under the conditions of long-term outdoor exposure to rainwater or wet, cold and high temperature environment choose to use stainless steel materials. In short, the stainless steel sign is characterized by durability and not easy to deform. Characteristics of aluminum signs: in terms of manufacturing process, the manufacturing of aluminum signs is much simpler and more convenient than that of stainless steel signs.
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.
The sign sign of the office building is the symbol of the modern sign guidance system as the static identification of the environment, it is an important indication of connecting people in daily life. Due to the multi-element alloy, the carbide Dispersion strengthening after solid solution strengthening and tempering is better, with high toughness, high impact fatigue resistance. Used for pneumatic tools, punching tools and large and medium-sized punching dies. The disadvantages are low compression resistance, poor thermal stability and difficult control of quenching deformation. For CrWzSi steel, when Shearing (Such as 5CrW2Si) High temperature heating quenching should be used as far as possible to change the shape of martensite and greatly improve its strength and toughness, which the author has achieved good results in practical work. Small signage nameplates are not made of aluminum, because the products such as logo signage nameplates made of aluminum are not as delicate as stainless steel, and the gloss is relatively poor, and the surface of aluminum signage is easy to be scratched. 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.

The design of
SiMnMo series Graphite Steel is characterized by high Si content. Under the action of strong graphitization element Si, some carbon exists in graphitization state, making the steel have self-lubricating effect, it has 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.
