In addition to the badge made of stainless steel, other materials must be used. Other materials are electroplated. The commonly used plating is generally nickel plating, which is also the white steel color we often say, this color is almost the same as the stainless steel color, so the customer mistakenly believes that it is a stainless steel badge. In the early days, it was made of metal materials such as gold, silver, copper, iron and tin, hence its name. In addition to metal materials, non-metallic materials such as plastics and glass fibers are widely used. According to the data of 'analysis report on development prospect and strategic planning of hardware products industry', in 2010, China's hardware products industry recovered throughout the year. In general, the hardware products industry is running well, the growth momentum of domestic and foreign sales is obvious, the import and export is growing at a high speed, and various economic indicators have basically returned to the previous level.
Shanxi large metal sign- Good quality and low price
In addition to metal materials, it is also widely used in non-metallic materials such as plastic and glass fiber. 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.
Shanxi large metal sign- High quality and low price, injection casting method: used to process complex shapes with high errors. Due to the characteristics of the process itself, the product does not need post-treatment after Molding. However, the advantage of low cost can only be shown in the case of mass production. Die casting method: the processing cost is high, and the cost is reasonable only in the case of mass production. However, the cost of the final product is relatively low and the error is relatively high. Can be used to produce parts with thin wall thickness. Rotary casting is an ideal method for processing small parts and is usually used in jewelry manufacturing. Rubber models can be used to reduce the cost of processing.
Shanxi large metal sign-It is of good quality and low price and belongs to labor-intensive production. The cost of processing can be relatively low. Solid forming processing classification spinning: A very common processing method for producing circular symmetrical parts, such as dishes, cups and cones. During processing, push the high-speed rotating metal plate closer to the model on the same rotating and fixed lathe to obtain the preset shape. This process is suitable for batch production.
what types of glue are commonly used in the use of metal signs? How is the glue correct and what type of sign or product is used? In the use of metal signs, we often use four kinds of glue: water glue, hot melt glue, back glue and four-dimensional glue. Water glue is a kind of liquid glue. The surface is colorless and transparent, and it is not easy to turn yellow. It is an environment-friendly chemical. It has good adhesive strength at normal temperature and is convenient to use. The release paper that tears the label can be directly attached to the product; Commonly used in electronic digital products, furniture, gift boxes, household appliances and other products.
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.
