This process utilizes machinery fitted with dies in order to transform sheet metal into custom shapes at incredibly tight tolerances. The manufacturer may even be able to complete the piece with a single stroke of the press, which is known as a single-stage operation. More complex pieces may require multiple strokes, which is referred to as a series operation. Precision metal stamping is flexible and adaptable, and is particularly beneficial for high-volume manufacturing.

Its immense level of precision, even for complex parts, is what sets this process apart from similar machining options. Precision metal stamping machinery enables manufacturers to perform microstamping, crafting complex minuscule parts where even the smallest error could render the final product ineffective. The accuracy and efficiency of precision metal stamping in crafting these parts has created a high demand in industries ranging from automotive to aerospace.
Projects using precision metal stamping will typically begin with computer modeling, virtually simulating the stamping process to check for errors or defects. Once this testing is complete, the computer will send the design straight to the machinery in an efficient process that reduces the chances of human error.
The factors affecting the life of stamping mold are design, use and maintenance. Only do a good job in each details, can the service life of the mold be prolong.
The life of stamping mold refers to the total number of parts that can be processed by the mold under the premise of ensuring the quality of the stamping parts, including the life after repeated mold repairs on the working face and the replacement of wearing parts for a precision metal stamping manufacturers in china. The life of high speed stamping die is generally divided into tool design life and service life. Under normal circumstances, the service life of the mold is greater than the design life of the mold.
The division of process content should be reasonable in progressive stamping process design to avoid too centralized design of process content; The stamping angle should be reasonable to avoid sharp corners on the inserts of the progressive die; The forming mold should try to make the material flow uniform to avoid the occurrence of wrinkling stacking phenomenon. Try to choose raw materials with good stamping technology to reduce stamping deformation force; Ensure the grade, thickness and surface quality of raw materials.
Reasonable dies&#; structure is conducive to improve the bearing capacity of the dies. When customer require a custom metal design stamp, a precision die and stamping inc should fully consider the stress and structural strength of each structural component.
The selection of stamping material is very important to the life of the mold. The material division of each component needs to be based on the stress of each component. In another words, It is according to the chemical composition, structure, hardness and metallurgical quality of the material itself.
There are two basic requirements for the material of the parts of the custom stamping dies:
The performance of material has high hardness and high strength, as well as high wear resistance and enough toughness.
With competitive price and timely delivery, Qisheng sincerely hope to be your supplier and partner.
The machining and manufacturing process of custom metal stamping parts is generally more complicated. Therefore, It is usually necessary to select mold materials with excellent performance according to the material characteristics.
The accuracy of the guide mechanism of the stamping dies is very important to the life of mold. An accurate and reliable guide mechanism has a great influence on reducing the wear of working parts of the mold and avoiding the bite of the mold.
Casting quality and forgings quality directly affect the life of the mold. Defects in casting and forgings may directly lead to the scrap of the mold. The sudden failure of hidden internal defects during use may cause irreparable safety accidents and have a great impact on production. Therefore, the quality control of stamping material is very important in the mold manufacturing stage.
The pros and cons of the surface quality of the working parts of the mold has a significant impact on the wear resistance, anti-gluing resistance, anti-fracture ability of the mold, and directly influence the service life of die, especially the surface roughness value had a great influence on the mold.
For all the mounting surface/hole and datum surface/hole that need to be assembled, in the case of guaranteed processing accuracy, the assembly must be assembled in accordance with reasonable assembly techniques to ensure the quality of each process. Assembly accuracy directly affects product quality and mold life.
The choice of heat treatment process and equipment has a great impact on the life of the custom metal stamping tool. That is to say, a good heat treatment process can give full play to the properties of the steel material of the tool. In order to achieve the hardness, strength, toughness and wear resistance required by the stamping tools. On the contrary, An unreasonable heat treatment process will cause carbonization of the mold body or insufficient hardness, thereby accelerating the wear of the tool and affecting the life of the tool & dies.
The precision and rigidity of stamping equipment are extremely important to the life of stamping die.
The guide parts of the mold are well lubricated and the working parts of the mold are free from cracks, unreasonable gaps and other defects. In general, correct use of mold is beneficial to increase mold life.
Disassemble all working parts and inclined wedge mechanism of the mold. Maintain and repair the moving parts, safety parts, elastic components, pneumatic components, unloading mechanism, auxiliary mechanism and so on.
We should use the advanced mold manufacturing technology and the implement mold manufacturing quality management in the design, manufacture, use and maintenance of the process of custom custom metal stamping dies. In order to develop specialized manufacturing processes, implement standardized operational process, continuously improve the equipment and environment for mold manufacturing. It can better to extend the service life of mould and ensure the quality of parts production.
