Stamping parts are used in a wide range of industries, including automotive, medical, electronics, household appliances and other industries. The selection of materials for stamping parts is very important. Stamping factories need to have strict requirements on the thickness of the material, because once the thickness of the material changes greatly, the use of the same mold and gap for production will affect the quality and accuracy of the product, and the mold will be damaged in severe cases. Even in the production of large stamping parts, production accidents still occur. According to Dongguan Fortuna's precise analysis, the thickness tolerance of stamping materials has an impact in the following process.1) In the punching process, the positive deviation of the thickness of the stamping material is too large, or the negative deviation is too large, which may cause burrs. Materials with too much negative deviation will increase springback and affect dimensional accuracy. Materials with too large positive deviation will increase the punching force and punching work, which may damage the punching equipment. Uneven material thickness will also produce unilateral burrs on the stamped parts.2) In the bending process, materials with large negative deviations have large springbacks, resulting in inaccurate shapes and sizes of stamping parts, and easily cause deflection and distortion. If the positive deviation of the material thickness is too large, it will cause curved surface extrusion, affect the surface quality of the stamping parts, and increase the bending force and bending work, which may damage the equipment. The uneven thickness will also lead to inaccurate shapes and dimensions of the stamped parts.3) In the deep drawing process, if the negative deviation of the material thickness is too large, the shape will be uneven due to springback, and the height of the stamping part will be insufficient, and the opening and bottom of the stamping part will be small. At the same time, The pressure will decrease. In addition, the relative increase in the gap between the male mold and the female mold causes the material to wrinkle during the stretching process, which increases the difficulty of the flow of the metal material, thereby increasing the stretching force, and causing the stamping to break during stretching.
For stamping factories, aluminum stamping parts are also a very common metal stamping part. Aluminum is light in weight, and products of the same size are relatively light, which can effectively reduce costs. Aluminum stamping parts generally require surface treatment to achieve some special work capabilities. Dongguan Fortuna has focused on precision metal stamping parts for more than ten years, and has accumulated rich experience in custom processing of stamping parts. Next, we will share some surface treatment methods of aluminum stamping parts, hoping to help everyone.Aluminum stamping parts1. AnodizingWhen it comes to the surface treatment of aluminum stampings, anodizing process has to be mentioned. Anodizing can effectively make up for the lack of surface hardness and wear resistance of aluminum stamping parts, and can also greatly increase the use time of aluminum stamping parts, making the product look more beautiful. Now, anodizing has become a common surface treatment method for aluminum stamping products. Anodizing refers to the electrochemical oxidation of metals or alloys. Due to the action of the current applied under the corresponding electrolyte and specific process conditions, aluminum and its alloys form an oxide film on the aluminum product (anode).2. sandblastingSandblasting is usually an intermediate process of surface treatment of aluminum stampings. After sandblasting, aluminum stampings can effectively remove surface burrs and oil stains. The surface of aluminum stamping parts can improve the cleanliness, and different surfaces can be obtained by controlling the sandblasting material. The roughness of the product. After sandblasting, the performance of the product can be greatly improved. In the subsequent surface treatment process, the adhesion between the aluminum stamping parts and the coating can also be increased, thereby making the product more durable and more beautiful.3. polishing treatmentPolished aluminum stamping parts can be close to the mirror effect, which greatly improves the grade and aesthetics of the product. However, due to the characteristics of aluminum products, aluminum stampings are relatively less polished. If other surface treatments are not performed after polishing, the durability will be relatively low. After aluminum stampings are polished, it is difficult to maintain the mirror effect for a long time. Generally, it is recommended to use stainless steel for products that require a mirror effect.4. wire drawing processingThere are many types of brushed aluminum stampings, the common ones are straight wire drawing, chaotic drawing, spiral drawing and thread drawing. After processing aluminum stampings by wire drawing, you can see clear and subtle traces on the surface, and the product gives a visual feeling of luminous silk grain.Aluminum stampings basically require surface treatment after processing, but the choice of treatment method depends on the specific requirements of the customer.
Stamping is a very common metal processing product, which is widely used in the electronics industry, machinery industry, furniture industry, automobile industry, etc. Auto stamping parts, as the name suggests, are stamping parts used in the automotive industry. Today, Dongguan Fortuna will introduce to you what are the requirements for stamping parts used in the automotive industry.1. When designing the geometry of automobile stamping parts, a simple and reasonable structure should be adopted, and the number of processing surfaces and processing area should be as small as possible.2. The materials used in automobile stamping parts must not only meet the technical requirements of product design, but also meet the process requirements of cutting, electroplating, and cleaning after stamping;3. Forming performance requirements for automotive stamping parts; in order to produce high-quality stamping parts, the material should have good plasticity, and the yield strength of the material should be less than the ratio of the elastic mold. For the separation process, the material does not have to have good plasticity. The better the plasticity, the more difficult the separation.4. The stamping oil used in the processing of automotive stamping parts should meet the process requirements. Special stamping oils with excellent performance can optimize the processing environment and improve the accuracy of parts.
