Generally speaking, steel with a content of more than 12% Wcr has the characteristics of stainless steel. Stainless steel can be divided into five categories according to the microstructure after heat treatment: namely ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, austenitic- Ferritic stainless steel and precipitated carbonized stainless steel will suffer from damage, defects and some substances affecting the surface, such as dust, floating iron powder or embedded iron, hot tempered color and other oxide layers, rust spots, grinding, welding arc spots, welding spatter, flux, welding defects, oil and grease, residual adhesives and paints, chalk and marking pens, etc. 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.
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.
color label manufacturer- Professional, 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.
The appearance design of metal signs generally requires many factors such as humanization, standardization, coordination between products and environment, etc. What are the factors that affect the appearance design of metal signs. Humanized factors the appearance design of metal signs should be combined with the actual situation, sensory vision, and design according to local conditions, reflecting the people-oriented concept and improving customer satisfaction, such: the sign design of scenic spots should reflect the service concept of humanization, individuation and characteristic on the whole and in detail, so as to greatly enhance the reputation of scenic spots.
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.
these signs that can be seen everywhere are made of different materials and processes, the focus of this article is also to introduce the material classification of signs and their main application fields, so that you can distinguish different materials when purchasing signs and have a general understanding of the process and cost. Plastic signs plastic signs we usually see outside electric cars, bicycles are used to plastic signs, hotels and other public places can also see a lot of plastic signs, as well as plastic business cards and so on. Plastic signs are generally made of plastic and screen printed.
The manufacturing process of nickel sheet thin target is to use the cathode deposition phenomenon in the electrochemical process to carry out molding processing, I . e. the conductive original mold is used as the cathode, using Electroformed Metal as anode and metal salt solution of electroforming material as electroforming solution, under the action of direct current, the metal plate at anode will gradually dissolve into metal ions, it is continuously added to the electroforming solution to keep the concentration of the electroforming solution balanced.
W18Cr4V (1220 ℃-Heating and quenching at 1250 ℃), W6Mo5Cr4V2 (Use 1170 ℃-1190 ° C) The mould treated by low temperature heating and quenching has high plastic deformation resistance, high hardness and wear resistance; There is enough blade property. Practice has proved that the punch quenched at low temperature can significantly prolong the service life and greatly reduce the fracture accident of the punch. Ductile cold deformation die steel some cold extrusion dies and cold heading Dies need to bear high strength and high impact toughness, while ordinary high speed steel and high carbon chromium rigid parts are easy to brittle break or break, and the dies need to have high strength and toughness, it can be divided into two categories: Carbon High speed steel: W series or Mo series high speed steel with carbon content reduced to 0. 5-0. 6%, increase the toughness of the treated steel.
color label manufacturer- Professional receiving engineering drawings are customized according to CDR, AI or cad format engineering drawings provided by customers and technological requirements such as size, color, thickness, glue, etc, the logo design in the drawing shall not be less than 0. 25mm (For example, the I word is only 0. , Then the drawings must be changed, or communicate with the customer to change the size, otherwise the size is too small, it is difficult to take it down during the shipping process, resulting in the improvement of defective products) After confirming the drawings, we will first make samples and send samples to the customer for confirmation. After confirmation by the customer, the order will be made.
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.
