injection molding. The injection molding adopts granular materials prepared by suspension polymerization and is molded on ordinary plunger or screw injection molding machines. Sand mold casting: low cost, small batch, can process complex shapes, but may require a large number of post-processing procedures. 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.
Maoming sun-resistant label electroforming factory professional
Hot Melt Adhesive is a plastic adhesive, no viscosity at room temperature, 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!
Maoming sun-resistant label electroforming factory is professional and has entered many industries in 1980s, 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.
Maoming sun-resistant label electroforming factory is specialized in chemical stability of the material itself: stainless steel has the properties of high temperature resistance, acid and alkali resistance, corrosion resistance, oxidation resistance, etc. , and is 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?
aluminum plate is cheaper than stainless steel plate, and because the manufacturing process of aluminum plate is relatively simple and fast, there is no complicated manufacturing process of stainless steel plate, therefore, the production cost is also low. Metal signs are signs that can be seen everywhere in our daily life and can be found in many products or places; For example: mobile phones, computers, electronic digital products, household appliances, gift box packaging, bags, leather goods, cards, indication signs, etc. Commodity decoration: for example, the sign decoration of electronic products, household appliances, luggage, gift boxes and other commodities highlights the cultural concept given by the Enterprise to the commodities and a quality hint given to customers, let people think of the company and the products produced by the company as soon as they see the trademark.
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.
