During the production process of precision stamping parts, stamping parts manufacturers need to formulate guidelines and require operators to strictly control the quality of products in accordance with the guidelines. Fortuna has been engaged in precision stamping for decades, has accumulated rich experience, and has also summarized some for your reference. Dongguan Fortuna metals CO.,LTD will introduce the three major principles of quality control of precision stamping parts:1. Maintain and optimize quality levels.a. The operator is clear about the current quality level, the overall goal to be achieved and the relative regulations.b. Quality information content of supervision and manipulation steps.c. Analyze the reasons and take effective preventive measures. 2. Carry out the confidence of "quality is produced by production"a. Inspect the first and last batch of stamping die products for each production line.b. Carry out regular inspections to avoid unqualified products.c. Supervise whether the staff is working in accordance with the work norms. 3, when it is found that the quality is not up to standard, effective preventive measures can be taken.The unqualified products attributed to the internal cause should be repaired and reported to the person in charge and put forward opinions and preventive measures.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined Parts
Good mold design can improve mold life, durability, production efficiency, reduce production costs and ensure product quality. So what should we pay attention to when designing the mold? The following editor will introduce 13 things that must be paid attention to when designing precision metal stamping dies.1. Before designing the material belt, be sure to understand the tolerance requirements of the parts, material properties, punch tonnage, punch table, SPM (punch times per minute), feeding direction, feeding height, mold thickness requirements, material utilization, and mold service life .2. When designing the material belt, CAE analysis should be carried out at the same time, mainly considering the thinning rate of the material, and more communication with customers.3. The design of the material strip is an analysis of the molding process of the product, which basically determines whether the mold is successful or not.4. In mold design, mold material selection and heat treatment and surface treatment, especially metal drawing parts.5. When trying the mold for the first time, the upper mold must be slowly closed. When there is a stretching process, the thickness of the material level must be tested with a fuse. After the material level gap reaches the material thickness, the mold must be tested first. Right. For drawbeads, please use movable inserts to adjust the height of the drawbeads.6. When trying out the mold, the reference hole and reference surface must be matched with the mold before placing the product on the inspection tool for measurement, or sending it to CMM for 3D report.7. The red pill must be well matched, otherwise the product will be unstable, and it will not be possible to make a judgment on the modification of the mold in the later stage, and the size of the parts will not meet the customer's requirements.8. For parts with more bending, the bending should be adjusted step by step according to the process when adjusting the mold.9. When adjusting the forming angle, the R angle during bending can be reduced or the folding line reference can be moved to achieve the purpose of forming the forming angle.10. When adjusting the mold, most of them use gaskets to adjust the height of the forming male, or move the forming male parts left and right, back and forth, and the gaskets generally use stainless steel hard sheets.11. For the trimming line affected by molding, it is necessary to choose to cut it after molding, and the special position can be realized by cross-cutting.12. For multiple reference hole positions, the method of punching and forming is adopted at one time to avoid affecting the accuracy after step-by-step punching.13. For product breakage, it can be carried out in a variety of ways, such as adding wrapping, extruding material, increasing the forming area of the sheet rod, and opening holes in the early stretch. CAE analysis should be carried out before the mold is changed.The above is a summary of some experience in actual stamping work, I hope it will be helpful to those who read this article.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined Parts
The mold industry is very complicated, and technology requires a long time of accumulation and practice. Dongguan Fortuna can design and manufacture stamping toolings according to the different needs of customers, and apply them to internal production, and has accumulated rich experience in mold technology. Below, the technical staff of Dongguan Fortuna will share with you some experience in designing and designing products of precision stamping tooling. 1. The punching position of the product is too close to the bending edge, the punching hole will be deformed after punching first, and the punching hole after punching first has no strength. At this time, in order to ensure the size, it is recommended to open the process hole at the bending position to avoid the hole position. 2. Similar to the convex hull with the corner, the corner position is very easy to break due to the pulling material. In order to ensure the appearance, it needs to be changed to a process hole to remove the corner position. 3. The bending position often bends to the inside of the material. In fact, the product is very ugly. In order to ensure the stability of the angle and the appearance, it is necessary to add a process groove at the bending position. 4. The bending position is directly connected to the product plane, which is prone to cracking after bending. In order to ensure the bending angle and appearance, it needs to be improved to bend with a straight section, and the improved height H is preferably not less than 2T. 5. The bending angle is too large. In order to ensure the stability of the angle and reduce the rebound when the mold is used for one-time molding, a bulge (called: reinforcement rib) can be added in the middle to ensure stability and stress. 6. When the product material is thick, the product position is prone to cracks or even cracks after bending. In order to reduce this situation, try to keep the punching burr on the inside of the bend.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined Parts
Stamping dies, as the name suggests, are dies used in stamping production, which are very important for stamping parts production. If stamping factories want to better produce stamping parts, they need to understand the classification of stamping dies. Dongguan Fortuna Metals CO.,LTD. has been focusing on the customized processing of precision stamping parts for more than 30 years, and has also accumulated rich experience in mold processing. Next, I will share with you the classification method of stamping dies.1. According to the feeding methodAccording to different feeding methods, it can be divided into manual feeding die, semi-automatic die and fully automatic die.The manual feeding die does not require special feeding equipment, the die is relatively simple, the production is convenient, and the application in stamping production is extremely common.Semi-automatic punching dies and fully automatic punching dies need to be set up with special feeding machines and equipment. There are strict regulations on punching machines, high production preparation costs, and high performance regulations, which are only suitable for mass production.2. According to production adaptabilityAccording to the requirements of different production and operation scales, it can be divided into two methods: general-purpose die and special-purpose die.General-purpose dies include combined dies, general-purpose bending dies, etc. The former one is suitable for small batches and multi-type production methods.Most of the stamping dies used in general production are special-purpose dies, that is, a pair of dies only stamps one or several types of parts.
