Fortuna multi function metal stamping service factory for connecting devices

There are many stamping materials to choose from, and if the performance of the material and the processing process can be considered together, the stamping process can be continuously improved, which is conducive to the precision, beauty, and durability of the product. The benefits are obvious. How to choose materials for your stamping parts processing?1. It is not advisable to use materials with small strain hardening exponents for tensile partsThe strain hardening exponent has a very close relationship with the formability of sheet metal. According to the plastic deformation limit theory, the maximum elongation strain when the sheet is subjected to concentrated stretching is twice that of uniaxial stretching. Under normal conditions, the material will rupture immediately after the necking concentration occurs. Therefore, the larger the strain hardening exponent of the material, the stronger the ability of the material to resist local fracture, the distribution of plastic strain tends to be uniform, and the peak strain is lower. Therefore, materials with a small strain hardening exponent should not be used in molded parts dominated by elongation.2. The compression molding process should not use materials with poor stabilityIn compression forming, the deformation zone is mainly achieved by compressive stress and compressive strain to undergo compressive deformation. Sheets are prone to instability and wrinkling under compressive stress. In order to improve the stability of plastic deformation, it is not suitable to choose materials with poor anti-instability ability.3. The stretching process should not use materials with poor plasticityIt is not suitable to use materials with low elongation during the stretching process. The better the plasticity of the material, the higher its uniform elongation, which means stretching between stable deformation and uniform deformation.4. Hardened material should not be used in spinning processCommon spinning materials are mainly pure aluminum, low carbon steel and stainless steel, of which low carbon steel and stainless steel account for more than 60%. For ordinary spinning, soft materials with good plasticity, low yield point, less impurities and uniform structure should be used.5. High-strength, low-plasticity materials should not be used in the cold stamping processThe cold stamping process should not use high-strength, low-plastic materials to avoid increasing deformation resistance and crack resistance. The requirements for cold stamping and other volume forming of materials are: materials should have high plasticity, low yield point and low work hardening sensitivity. Commonly used cold stamping materials are pure aluminum and aluminum alloys, copper and copper alloys, low carbon steel, medium Carbon steel, low alloy steel, etc. Products stamped with this material have a smooth surface, dimensional accuracy and can withstand high pressure. One-time plastic deformation, punching out products with complex shapes.6. High elastic materials should not be used in the bending processSteel for stamping and bending needs to have good plasticity, low yield strength and low elasticity. The steel with good plasticity is not easy to bend and crack during the bending process. Its low output, high strength and low elasticity steel has small rebound deformation after bending, and it is easy to obtain accurate bending shape.7. Materials with poor plasticity should not be used for elongation formingDuring the stamping process, flaring, reaming, bulging, bending, eversion and partial stretching are extension-type deformations. Since the deformation zone is mainly subjected to tensile deformation by normal stress and normal strain, the material in the deformation zone is prone to excessive elongation. When the elongation exceeds the ultimate elongation of the material, it is easy to break, so it is not suitable to use materials with poor plasticity in the elongation forming process.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined PartsPrecision Stamping Products

When the precision stamping factory receives the order, it needs to formulate a detailed plan rigorously to avoid various problems in the subsequent actual production and processing, which will affect the production efficiency and product quality, resulting in waste of time and cost. So what preparatory work do stamping parts need to do after receiving the order? Let's introduce it below.1. Analyze drawings of precision stamping partsAfter receiving the drawings of precision stamping parts from the customer, we must confirm the quantity of the product and the specific dimensional tolerance requirements with the customer at the first time, and then determine which process to use for production. For example, when the batch size required by the customer is relatively large, we can Stamping and stretching processing technology is adopted to reduce product cost.After determining the production process, it is necessary to design a reasonable discharge method to minimize waste.2. Develop a processing plan for precision stamping partsAfter analyzing the drawings of precision stamping parts, it is necessary to formulate an overall processing plan. Some precision stamping products are not only achievable by the stamping process, but also include other processing processes, such as: riveting, welding, drilling, laser cutting , tapping and so on. This requires the development of a sequence of various processing techniques.3. Determine the number of processing steps and dimensionsThe vast majority of stamping parts require multiple processes to be processed, and a reasonable number of processes must be designed. A reduction in the number of processes means a reduction in product costs.After determining the number of processing procedures, it is necessary to understand the shape and size of the product after each procedure, and determine the size and shape of the product blank.4. Design of stamping dieWhen designing stamping dies, we must pay attention to ensure the operability and safety of the dies. The wearing parts are also designed to be detachable, which is convenient for future maintenance.5. Choose the right punchThe required stamping force is calculated according to the dimensions and thickness of the precision stamping parts. In addition, the size of the working surface of the punching machine must conform to the size of the product.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined PartsPrecision Stamping Products

The development of metal stamping parts enterprises has encountered a lot of resistance, and is now in a period of severe challenges, especially now that it has been affected by the Covid-19. If you want to continue to seek development, you need to take certain measures and actions. So what are the problems facing the metal stamping processing industry?1. Labor costs continue to rise.Now the older generation of metal stamping parts processing industry has retired at home, and young people have no reason to engage in the hard and boring work of stampingMost metal stamping parts processing factories in China are labor-intensive. There is a large demand for manufacturing workers and they cannot recruit people. Of course, wages will rise. In addition, prices have risen in recent years. If wages do not increase, they will not be able to recruit people.2. Vicious competition among peers.The threshold of the metal stamping parts processing industry is relatively low, resulting in a mixture of fish and dragons in the entire industry, and vicious competition inevitably occurs. Prices are constantly being driven down, and profit margins are already very thin.3. Prices and housing prices continue to rise.The price of raw materials and equipment required for the processing of metal stamping parts is also rising, which makes the pressure on the stamping factory continue to increase. The main reason is the increase in workshop costs.Dongguan Fortuna Metals CO,,LTD has been focusing on the mass production of high-precision  parts for more than 20 years.

With the continuous development of society, science and technology, the demand for metal stamping parts continues to grow, and the market has higher and higher requirements for them. In order to be able to produce metal stamping parts that satisfy customers, stamping parts manufacturers must continuously improve their technology, internal repair and external training, and continuous improvement. So what principles should we pay attention to in the production of metal stamping parts? Let's take a brief look at it.1. Metal stamping parts should meet product use and technical performance, and be easy to assemble and repair.2. It should be beneficial to improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce the consumption of materials as much as possible. Use low-cost materials where possible, and make parts as scrap-free and blank as possible.3. For metal stamping parts, it should be beneficial to use the existing equipment, process equipment and process flow as much as possible to process them, and to prolong the service life of the die.4. The designed stamping parts should make the dimensional accuracy grade and surface roughness grade as low as possible under the condition of normal use, which is conducive to the exchange of products, reduces waste and ensures stable product quality.5. The shape of metal stamping parts is simple and the structure is reasonable, which is conducive to simplifying the mold structure and simplifying the number of processes, that is, the processing of the entire part is completed with few and simple stamping processes, and the use of other methods for processing is reduced. The organization realizes mechanization and automation of production to increase labor productivity.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined PartsPrecision Stamping Products
