any city is developing continuously. The disappearance of the old urban landscape does not mean the annihilation of urban personality, the design of signs, notices and directions will tend to be uniform. 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.
metal signs are widely used in daily life, not only for these purposes listed above, such as road signs, campus education guidance and signs, etc, these are the common uses of metal signs in our daily life; So don't underestimate the role of small signs, it brings many convenient uses to our life.
Foshan cool electroforming label production manufacturer professional Hot Melt Adhesive is a kind of plasticity of adhesive in at room temperature under no viscous, it needs to be heated by a hot press to above 120 ℃, and the glue will be sticky only when dissolved, and it has no tasteless 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!
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?
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.
SiMnMo series Graphite Steel is characterized by high Si content. Under the action of strong graphitization element Si, some carbon exists in graphitization state, the steel has 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.
Foshan personalized electroforming label manufacturer is specialized, such as 6W6Mo5Cr4V2, and 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.
