The die used for metal stamping dies is called a stamping die, or simply a die for short. Stamping dies are specialized tools for batch processing materials (metals or non-metals) into the required stamped parts. Meanwhile, in modern manufacturing, metal stamping dies are the core tools for batch production of metal components, and their processing quality directly affects the precision, efficiency and cost of the products. The processing of metal stamping dies is a complex systematic project integrating design, precision processing, heat treatment and assembly and debugging. Its core lies in ensuring the dimensional accuracy, surface quality and performance of the dies through reasonable process planning and high-precision processing.
So, what exactly is the processing procedure of metal stamping dies? Dongguan Manye Precision Hardware Co., Ltd. provides you with a detailed answer
1.Manual grinding and polishing: Traditional surface processing methods for molds mainly rely on the operator's experience and skills. Manual polishing is time-consuming and inefficient. Some more complex curved surfaces or seam grinding and polishing can be quite difficult to handle.
2. Mechanical fine processing - CNC milling machine: This surface processing method for stamping dies not only features high processing efficiency but also excellent processing quality. It can handle all aspects except for cavities with sharp inner corners and extremely narrow and deep cavities.
3. Mechanical precision processing of metal stamping dies - grinding processing: Commonly used grinding processing equipment includes surface grinding machines, internal and external cylindrical grinding machines, and tool grinding machines. To ensure accuracy, numerical control is generally adopted for processing. The appropriate type of grinding machine should be selected based on the different shapes of the parts. For plate-type parts, surface grinding machines should be used, while for curved and rotary surface parts, internal and external cylindrical grinding machines or tool grinding machines should be adopted.
4. There are also some non-mechanical finishing methods, such as ultrasonic processing, electrical discharge polishing, laser finishing, chemical polishing, electrochemical polishing, etc.
The processing of metal stamping dies takes "precision and efficiency" as its core. Through the closed-loop control of "design - processing - assembly - debugging", combined with technologies such as numerical control processing, electrical discharge machining, and precision grinding, it realizes the transformation from drawings to high-precision dies. In the future, with the growth in demand for precision stamping parts in fields such as 5G and new energy vehicles, mold processing will rely more on automation and intelligent technologies to meet the market challenges of multiple varieties, small batches and high precision.
