<p><strong>Hardware stamping parts manufacturers</strong> must handle five points when processing precision metal parts in order to ensure the accuracy of the stamping parts. </p><p><br></p><p><strong>Five principles for processing precision metal parts</strong></p><p><br></p><p>1. The principle of precision</p><p><br></p><p>The number of processes for drawing parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, which can be confirmed only after drawing process calculations.</p><p><br></p><p>2. The principle of exquisiteness</p><p><br></p><p>When the section management and standard precision requirements of stamping parts are high, you can consider adding a trimming process after the punching process or directly choose to use a fine punching process.</p><p><br></p><p>3. The principle of finesse</p><p><br></p><p><br></p><p>The number of processes for bending parts mainly depends on the complexity of its structure, and metal stamping parts need to be determined according to the number of bending angles, relative orientation, and bending direction.</p><p><br></p><p>4. The principle of quality</p><p><br></p><p>In order to ensure the quality of <a href="https://www.ruibangwj.com/precision-metal-parts.html" rel="noopener noreferrer" target="_blank"><strong>precision metal parts</strong></a> and the stability of the processing technology of metal stamping parts, sometimes it is necessary to increase the number of processes, such as additional positioning technology for bent parts, increased deformation in the forming process, reduction of hole punching to transfer deformation areas. It can ensure that each product is refined and exquisite.</p><p><br></p><p>5. The principle of precision</p><p><br></p><p>Blanking the workpiece with a simple shape can be finished with a single-process die. When processing the metal stamping parts with a messy shape, the surface and the inside summary should be divided into several precision parts for blanking due to the restriction of the structure or strength of the die, which needs to be selected. It shall adopt multiple metal stamping processing procedures. Besides, continuous die can also be selected when necessary.</p><p><br></p><p>For workpieces with high flatness requirements, a leveling process can be added after the punching process to accurately adjust the characteristics of each product to the production process.</p><p><br></p><p><strong>Stamping processes for processing metal parts</strong></p><p><br></p><p>In the <a href="https://www.ruibangwj.com/precision-metal-parts.html" rel="noopener noreferrer" target="_blank"><strong>metal stamping parts</strong></a> processing plant, the cold stamping process is used to process metal stamping parts. Today, I will help you to understand the more commonly used processes in this stamping process.</p><p><br></p><p>1. Blanking process</p><p><br></p><p>Blanking is the basic process in the cold stamping process. Through blanking, the required metal stamping parts can be stamped out, and the blanks can be prepared for other cold stamping processes.</p><p><br></p><p>2. Bending process</p><p><br></p><p>Bending is a plastic forming process to make a flat blank into a workpiece with a certain shape angle and size requirements. The bending process uses different tools and equipment due to the different shapes of the processed metal stamping parts. Bending methods can be divided into press bending, bending, twist bending, roll bending and stretch bending.</p><p><br></p><p>3. Deep drawing process</p><p><br></p><p>Deep drawing can punch a flat blank of a certain shape into open hollow parts of various shapes through a drawing die, or use the open hollow machined parts as a blank to further change the shape and size of the hollow part through a cold stamping process.</p><p><br></p><p>The drawing process of metal stamping parts can be divided into two categories. One is to use a flat plate as a blank, which does not produce large thinning during the drawing process, and the thickness of the cylinder wall and the cylinder bottom are relatively consistent, which is called thinning and deep drawing. This is based on the hollow part with bottom opening as the blank, and the precision metal parts is formed by reducing the wall thickness, which is called thinning and deep drawing.</p><p><br></p><p>4. Forming process</p><p><br></p><p>The sheet metal forming process is a general term for the process of changing the shape and size of the blank through the local deformation of the sheet metal. Common forming processes include: bulging, flanging, necking, leveling and shaping.</p><p><br></p><p>For a metal stamping part, because of its different shape, size and purpose, the stamping process of the metal stamping part is different, and the stamping materials used are also different.</p><p><br></p><p>The process designer of the <a href="https://www.ruibangwj.com/" rel="noopener noreferrer" target="_blank"><strong>metal stamping parts factory</strong></a> should design and select a reasonable stamping process according to the requirements of the sample parts. While meeting the performance of the stamping parts, it should also be able to maximize the production efficiency.</p>
