Fortuna precise lead frame manufacturer for discrete device lead frames

Metal stamping parts are metal parts with certain shape, size and performance formed by stamping process. They are widely used and have broad market demand. What are the main features of metal stamping parts, do you know? Dongguan Fortuna Metals, a metal stamping manufacturer, has more than 20 years of experience in processing and customization, and will show you. 1. Stamping can process parts with thin wall, light weight, complex shape, good surface quality and good rigidity. 2. Save material There can be minimal or no waste, and in some cases even edges and corners can be fully utilized and made into other forms of parts to avoid waste. 3. The product has good interchangeability The dimensional tolerance of metal stamping parts is guaranteed by the mold, has the same characteristics, and generally does not require further processing, so the processing of the same product has high dimensional accuracy, good consistency, and good interchangeability. 4. High production efficiency Metal stamping processing with ordinary presses can reach dozens of pieces per minute; production with high-speed presses can reach hundreds or thousands of pieces per minute, which is suitable for larger batch production. 5. Simple operation, easy to organize production, easy to realize mechanization and automation. 6. Metal stamping has high production efficiency, high material utilization rate and low production cost.

Metal stamping parts are very common in our life. They are metal parts with certain shape, performance and size obtained through stamping process. Stamping parts with different materials and functions can meet various needs of the market. Next, Dongguan Fortuna Metals CO.,LTD will briefly introduce the process performance of metal stamping parts materials. Metal stamping parts Stamping material properties 1. Stamping performance: the ability of metal materials to withstand stamping deformation without breaking. Stamping at room temperature is called cold stamping, and the inspection method is tested by cupping test. 2. Forging performance: the ability of metal materials to withstand plastic deformation without breaking during forging. 3. Casting performance: Refers to some technological properties of whether the metal or alloy is suitable for casting, mainly including flow performance, ability to fill the mold; shrinkage, the ability to shrink the volume of the casting when it solidifies; segregation refers to the inhomogeneity of the chemical composition. 4. Welding performance: refers to the characteristics that two or more metal materials are welded together by heating or heating and pressure welding, and the interface can meet the purpose of use. 5. Performance of top gas section: refers to the performance of metal materials that can withstand upsetting without breaking. 6. Cold bending performance: refers to the performance of metal materials that can withstand bending without breaking at room temperature.

Metal stamping parts can be seen everywhere in our life, and our requirements for its surface quality are getting higher and higher. Stamping parts manufacturers will inevitably have scratches on the surface of metal stamping parts during the production and processing process. What should we do at this time? We first need to understand what causes it, such as the concave and convex mold, raw materials, processing technology, etc., and then find the corresponding treatment method. metal stamping parts, metal stamping 1. When the bending direction of metal stamping is parallel to the rolling direction of the material, cracks will occur on the surface of the stamping parts, which will reduce the surface quality of the stamping parts. When metal stamping bending is performed on more than two parts, it should be ensured that the directions of the two have a certain angle as much as possible. 2. When the burr surface is used as the outer surface for metal stamping and bending, stamping parts are prone to cracks and scratches, so the burr surface should be used as the inner surface of metal stamping bending. 3. When performing continuous bending operations on soft materials such as copper and aluminum alloys, metal particles or dross are easy to attach to the surface of the working part, causing large scratches on the stamping parts. The shape of the working part, lubricating oil, etc. should be carefully analyzed Under the circumstances, try not to appear scratches caused by particles and dross. 4. The gap between the convex and concave dies should not be too small, too small a gap will cause thinning and scratches. Always check the changes in the clearance of the mold. 5. The radius of the die fillet is too small, and there are impact marks on the bending part of the metal stamping. Polishing the die and increasing the fillet radius of the die can avoid scratches on the metal stamping bending parts. 6. When the depth of the punch entering the die is too large, the surface of the part will be scratched. In the case of ensuring that it will not be affected by springback, the depth of the punch entering the die should be appropriately reduced. 7. In order to make the stamping parts meet the precision requirements, the metal stamping bending die at the bottom is often used. When the metal stamping is bent, the spring on the pressing plate, the positioning pin hole, the supporting plate and the return hole, etc. will be pressed into Indentation, it should be adjusted.

Stamping has developed rapidly since its emergence in the field of metal processing. In people's daily life, stamping parts are widely used, involving all aspects of life. What basic processing principles should be followed in stamping processing? Next, Dongguan Fortuna Precision will share with you. 1. Each stamping part needs to consider the technical standard and model size of stamping processing at the design level, so that it can achieve the expected effect during assembly or use, thereby improving the technical advantages, and also creating various stamping processes in the process of processing specialty. 2. In the process of processing, the shape of the stamping part needs to be as simple as possible, so the design of the mold also needs to be as simple as possible to meet the manufacturing specifications of the stamping die. From the perspective of the processing technology of the stamping parts processing plant, the technical advantages and characteristics have been improved. Only by constantly discovering the processing characteristics, can better processing advantages be produced. 3. The designed stamping parts need to be conducive to improving the utilization rate of gold materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. Use low-cost materials where possible, and make parts as waste-free and waste-less as possible. 4. It should be conducive to the use of existing equipment, process equipment and process flow to process it as much as possible, and to prolong the service life of the die.
