The high scrap rate of metal stamping parts manufacturers will increase production costs. This requires us to optimize the production process from multiple perspectives, improve the production process, provide raw material utilization, and increase quality control capabilities in combination with actual production. So what are the specific solutions, let's take a look.1. Dongguan Fortuna stamping parts processing manufacturers analyze the reasons for the high rejection rate(1) Materials do not meet the standards, the performance is unstable, and the dimensional tolerance is large, resulting in unqualified accuracy.(2) The mold is not installed correctly.(3) During the cutting process, the operator did not install the feeding positioning device.(4) After the mold is used for a long time, the gap becomes larger and the parts are worn.(5) During stamping, the die is subjected to excessive impact force, resulting in loosening of bolts or parts, affecting quality.(6) The stamping personnel did not operate in accordance with the operation manual formulated by the company.2. Solutions proposed by Dongguan Fortuna stamping manufacturers(1) When purchasing raw materials, it is necessary to strictly follow the production standards. If the factory conditions permit, the steel composition, surface roughness and dimensional accuracy should be tested, and qualified raw materials are the premise to ensure the quality of stamping parts. When purchasing raw materials, choose a regular steel dealer or choose from a large steel mill.(2) After designing the stamping process, the stamping workers must strictly abide by the process regulations during the operation. Each stamped product has a different stamping process, which requires managers to formulate a specific product before processing the product.(3) The punches and stamping dies used in the factory should always be in stable operation and should be regularly maintained and overhauled.(4) Formulate a complete quality inspection charter. The first batch of products should undergo full/surface testing before formal production, and sample testing should be carried out regularly during the production process.(5) Use appropriate tools for feeding to avoid scratching the product.(6) When stamping, pay attention to keep the mold clean, and the workpieces and raw materials in the workshop should be placed in an orderly manner.
Dongguan Fortuna has been committed to precision metal stamping custom processing for more than 20 years. We can design and manufacture stamping according to the different needs of customers, and apply them to internal production. Below we will introduce the procedures and principles of precision stamping die assembly.The key to die assembly of precision stamping parts is how to ensure that the relative positions of the convex and concave dies installed on the upper and lower die bases and various parts related to them can work normally when the mold is closed, and punch out workpieces that meet product requirements. To this end, it should be mentioned that all kinds of parts put into assembly must meet the processing requirements of the assembly process for all kinds of parts. For example, for the fixing plate with multiple punches, the relative position dimensional accuracy and step distance accuracy of each type of hole must be consistent with the die and the stripper plate; the bolts and pins on the backing plate have a large gap through the holes, which can Drilling according to the size of the drawing, after quenching, the upper and lower surfaces should be strictly ground; the overall die installed on the upper die seat or the lower die seat, in addition to the processing of each hole conforming to the requirements of the drawing, should also be processed out bolts Holes and pin holes, which are put into assembly after heat treatment and finishing, need to be connected to the fixed die base and guide plate.The screw holes and pin holes on them should be drilled and matched according to the corresponding holes on the die during assembly. hinge. Based on this, although the types and structural characteristics of precision stamping parts are different, the assembly methods and installation sequences used are also different, but the assembly principles that should be followed are the same.When assembling a precision stamping die, it is first necessary to select an assembly reference piece, which is used as the assembly benchmark of the precision stamping die, and then gradually assemble other die parts according to the reference piece; the selection of the reference piece depends on the structural characteristics of the precision stamping die; The guide plate that also serves as the stripper plate should be selected as the assembly reference part; the precision stamping part dies guided by the guide post usually use the female die as the assembly reference part; It is a prerequisite that the output center/center of the ejector plate is aligned with the center/center of the die handle.After the reference part is selected, the various parts of the precision stamping die are first assembled into assemblies according to the individual connection relationship between them, and then the final assembly of the precision stamping die is carried out with the reference part as the assembly benchmark.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined PartsPrecision Stamping Products
With the continuous development of society and technology, labor costs continue to rise, and many manufacturers are faced with opportunities and adjustments for transformation and upgrading. The introduction of automation equipment by stamping manufacturers has greatly improved efficiency and reduced production risks while reducing production costs. coefficient. Next, let's take a look at the advantages of stamping manufacturers using automated equipment.1. Significantly improve material production efficiencyAfter the implementation of stamping automation, part of the stamping process does not require manual intervention, and fully automatic production greatly improves the entire stamping efficiency. In production, it is necessary to continuously improve the process technology and continuously increase the production capacity.2. Effectively reduce manufacturing costsThe use of automated equipment can achieve high-speed processing, greatly reducing the production time, thereby obtaining higher economic benefits. At the same time, the service life of the stamping die can be extended. However, it should be noted that the economic benefits obtained after stamping automation are gradually greater than the investment in production equipment, that is, attention should be paid to the overall benefits of stamping production.3. Reduce the footprint of metal stamping factory spaceThe application of automation equipment reduces the workshop area required for the storage, transfer and accumulation of raw materials between each process and equipment; due to the compact installation location of multiple presses, more space can be reserved for production use.4. Reduce the risk factor in productionIt fundamentally solves the insecurity/safety factor of the stamping operator's hands entering the stamping work area. In some automatic production environments, the operator may not even enter the production site to ensure personal safety/safety in the production process. In addition, once automatic monitoring and corresponding automatic protection devices are used in all aspects of stamping production, equipment accidents and mold damage can be avoided.5. Reduce the labor intensity of workersWith the continuous increase of raw materials processed in the stamping process, the processing speed of workers will also decrease, and manual operation is a heavy manual labor. When the weight of the stamping parts is very large, the handling speed of the workers will be greatly slowed down, and the production efficiency will be reduced accordingly. After the stamping automation is realized, it can break through the physiological limit of labor and move relatively heavy stamping parts at high speed, so as to get rid of the heavy stamping labor and improve working conditions.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined PartsPrecision Stamping Products
Cleaning is an indispensable process in the production and processing of precision stamping parts. I believe everyone knows what cleaning method to choose. This article will briefly introduce the stamping parts manufacturer when cleaning precision stamping parts and when there are cleaning accuracy requirements What methods are there to choose from.According to the requirements of cleaning accuracy, it is mainly divided into three categories: general precision industrial cleaning agents, industrial cleaning agents, and ultra-precision industrial cleaning agents.1. Precision industrial cleaning includes cleaning in the processing and production of various products, cleaning of various materials and equipment surfaces, etc., which is characterized by the ability to remove tiny dirt particles.2. General industrial cleaning agents include cleaning of the surfaces of vehicles, ships, and aircraft. Generally speaking, only relatively coarse dirt can be removed.3. Ultra-precision cleaning includes ultra-precision cleaning of mechanical parts, electronic components, optical components, etc. in the process of precision industrial production, with the purpose of removing extremely small dirt particles.According to the different cleaning methods, it can be divided into chemical cleaning and physical cleaning.1. Relying on the action of chemical reactions, the method of using chemicals* or other solvents to clean up the dirt on the surface of objects is called chemical cleaning. For example, various inorganic or organic acids are used to remove rust and scale on the surface of objects, and oxidants are used to remove stains on the surface of objects.2. Using the principles of mechanics, acoustics, optics, electricity, and heat, and relying on the action of external energy/energy, such as mechanical friction, ultrasonic cleaning, negative pressure, high pressure) to hit. The methods of removing dirt on the surface of objects such as ultraviolet rays and steam are called physical cleaning.These are some of the methods of cleaning.More Recommendations:Metal Stamping Parts ManufacturerCustom Metal StampingCNC Machined PartsPrecision Stamping Products
