Precision mold manufacturing is the core supporting link of high-end manufacturing. Electrical discharge machining (EDM), as the core process for processing complex cavities and high-hardness materials, has long faced industry pain points such as carbon deposits affecting workpiece quality, difficulty in micron-level precision control, low cutting efficiency of high-hard materials, and deformation of the fuselage during long-term operation. These bottlenecks are particularly prominent in high-end scenarios such as automotive molds and aerospace precision component manufacturing, and directly restrict the pace of upgrading of downstream industries.
The local equipment manufacturing company located in the “Mold Capital” of Huangyan, Taizhou, Zhejiang, has been deeply involved in the field of precision EDM machine tools since its establishment. By integrating core technologies such as pulse power control and intelligent discharge algorithms, it has now created an equipment matrix covering more than ten products, and has provided customized solutions to more than 200 industrial customers. It has occupied a stable market share in the Yangtze River Delta mold industry chain.
In response to the core pain points of the industry, the company has built a complete technical response system from three dimensions:
1. High-gloss processing technology to overcome the problem of carbon deposits
The entire series of CNC EDM machines launched by the company can achieve processing capabilities of 0.2μm surface roughness. The realization of this performance relies on multiple technical guarantees: the independently developed A-series pulse power supply can provide stable high-frequency pulse output to ensure uniform discharge gaps; coupled with real-time monitoring of intelligent discharge algorithms, processing parameters can be automatically adjusted to meet complex cavity processing needs.
Among them, the CNC450 model has been used in stainless steel material finishing processing scenarios. With its built-in anti-carbon deposition function, it can directly meet the processing standard of 0.2μm roughness, significantly reducing or even eliminating the subsequent polishing process, and providing a systematic solution to the carbon deposition pain point of traditional EDM.
2. High rigidity structure ensures long-term operation accuracy and stability
The entire equipment adopts the one-piece Meehanite cast iron casting process. The shock-absorbing performance of the material is 10 times higher than that of conventional cast iron. With the fuselage structure optimized by CAE simulation, it can achieve micro-deformation control under long-term operation.
At the supply chain level, the company has integrated the world’s top core components, equipped with linear rails imported from Switzerland, Japanese high-precision bearings and servo systems, to improve the stability and service life of the equipment on a hardware basis.
Among them, the large-size model CNC1880 has successfully completed the high-precision molding task of large-scale mold frames in the aerospace field through lightweight and high-load-bearing structural design, verifying the reliability of the high-rigidity and seismic-resistant structure under heavy-load conditions.
3. Intelligent operation + special equipment covering multiple scenarios
The entire series of equipment is equipped with a highly integrated control system that supports dual-mode operation of touch screen input and manual control box, which lowers the threshold for equipment use and improves the efficiency of human-computer interaction. The system’s built-in intelligent algorithm can automatically optimize discharge parameters, allowing operators to quickly adapt to different materials and processing requirements without the need for complex process debugging.
For large mechanical parts and heavy cutting conditions, the company has also launched special equipment series such as multi-head spark machines, double-head spark machines, and CNC electric pulse machine tools. The multi-head configuration can achieve synchronous processing mode, which can greatly improve rough machining efficiency in heavy cutting scenarios of automotive parts and shorten the delivery cycle of large and complex parts. The optimized CNC electric pulse control technology can accurately control pulse width and current parameters, providing a feasible solution for spark processing of high-hardness and difficult-to-machine materials such as titanium alloys.
Relying on the location advantage of Taizhou Huangyan Mold Industry Cluster, the company can radiate to mold manufacturing concentrated areas such as Ningbo, Shanghai, and Jiangsu in the Yangtze River Delta, and provide customers with full-process services including equipment selection, process debugging, and technical support. The supporting service network can quickly respond to customer needs and provide timely technical support and spare parts guarantee.
The current global manufacturing industry continues to increase its precision requirements for precision machining. Micron-level processing capabilities, complex geometric structure forming technology, and efficient processing solutions for difficult-to-machine materials have become core needs in the high-end manufacturing field. The company’s independent and controllable EDM equipment system built on the “specialized, special and innovative” development path not only provides domestic mold manufacturing companies with a cost-effective localization option, but also explores a feasible development path for the technological upgrading of domestic high-end precision processing equipment.
