why do most customers say that stainless steel badges are not stainless steel? Because there are many processes that cannot be achieved by using stainless steel to make badges, stainless steel generally only makes some etching or printing processes, and both processes are basically flat, or the etching is only slightly concave and convex, so that the effect that the customer wants cannot be achieved, and it will inevitably be completed by stamping or die casting, but both processes cannot be made of stainless steel. 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.
sand mold casting: low cost, small batch, can process complex shapes, but may require a large number of post-processing processes. 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.
self-adhesive label manufacturers are of good quality and low price, bending: an economical production process for processing any form of sheet, Rod and tubular materials. Continuous binding and forming: feed metal sheets between pressure rollers to obtain metal shapes with continuous length and consistent cross section. Similar to the extrusion process, but the wall thickness of the processed components is limited, only a single wall thickness can be obtained. Only on the premise of mass production, the processing cost is reasonable. The stamped metal sheet is placed between the male die and the female die and is pressed and formed for processing hollow shapes, and the depth can be deep or shallow.
adhesive backing is not suitable for signs like split signs or signs with small lines. Adhesive backing has strong adhesion, good retention, strong temperature resistance and good waterproof performance, it is an environmentally friendly chemical. Four-dimensional glue commonly used in digital products, household appliances, furniture, mechanical equipment, car key chains and other products is a glue with strong viscosity among these common glues.
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.
chemical stability of the material itself: stainless steel material 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 environments, such as high temperature, wet and cold, and long-term exposure to rainwater, stainless steel signs can still remain bright and beautiful for a long time without 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?
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.
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.
self-adhesive labeling manufacturers have excellent quality and low price. The nickel plating crystals are extremely fine and have excellent polishing performance. The polished nickel coating can obtain a mirror-like luster appearance while maintaining its luster in the atmosphere for a long time. Therefore, the plating layer is often used for decoration. The hardness of nickel coating is relatively high, which can improve the wear resistance of product surface. Nickel plating layer is commonly used in printing industry to improve the hardness of lead surface.
take the film and stick it to stainless steel. When sticking it, be careful not to stick it backwards. The side of the film is facing down and placed on the glass; Turn on the lamp tube, vacuumizing time is 25±5 seconds, and exposure time is 28±3 seconds; The exposure is completed and transported to the development workshop via the transmission output port. Development: The operator dips the exposed stainless steel plate into the developing liquid and puts 4 ~ 6 tablets.
