More than 95% of the badges are stamping and die casting processes, these two processes can be used to make some badges with a very three-dimensional feeling, especially die-casting is suitable for Super three-dimensional or 3D three-dimensional badges. 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.
punching: using special tools to punch and cut a certain shape on the metal sheet can be applied in batch production. Punching: it is basically similar to the punching process. The difference is that the former uses the punching part, while the latter uses the rest of the metal sheet after punching. Shearing: cutting metal sheets by shearing is the same as cutting paper from the position by a pair of scissors. Chip Forming: when cutting metal, the cutting method of chip production is collectively referred to as chip forming, including milling, drilling, lathe processing, grinding, sawing and other processes.
Shenzhen split nickel standard manufacturer integrity, 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!
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.
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.
The manufacturing process of nickel sheet thin standard 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.
Shenzhen split nickel standard manufacturer is honest, high wear-resistant micro-deformation cold deformation die steel is represented by Cr12Mov type, which is a high-performance cold deformation die steel widely used abroad. Cr12Mov is an improved Cr12 steel. The carbon content is too high, resulting in serious uneven large bulk carbides. Cr12Mov steel is characterized by high wear resistance and hardenability. It is a micro-deformation cold blanking die. The main material of cold heading die is still widely used in general factories. The modified material has high hardness and high wear resistance, high hardenability, especially small deformation after heat treatment, good filing performance during pliers processing, is still widely used in blanking forming dies, drawing dies and other dies.
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.
