Technological innovation of electric isostatic pressing machine promotes the upgrading of powder material preparation
Date: 2025-07-10Read: 7
With the rapid development of new materials and new energy industries, electric isostatic pressing machines, as key equipment for powder material forming, are ushering in a new round of technological breakthroughs. This device replaces traditional hydraulic drive with an electric servo system, demonstrating significant advantages in precision control, energy conservation, and environmental protection. It provides a better solution for the preparation of materials such as lithium battery positive and negative electrode materials and ceramic powders.
Technological breakthrough highlights
1. Precision pressure control
Adopting a high-precision electric servo system, the pressure control accuracy can reach ± 0.5%, far exceeding the ± 2% of traditional hydraulic equipment. Combined with a closed-loop feedback system, precise programming of pressure curves can be achieved to meet special process requirements such as gradient suppression.
2. Energy saving and environmental protection advantages
The electric drive system saves more than 30% energy compared to hydraulic systems, and avoids the risk of hydraulic oil leakage, which meets the requirements of modern manufacturing green production. The working noise is below 65 decibels, greatly improving the working environment.
3. Intelligent operation interface
Equipped with a 10 inch touch screen control panel, it supports digital settings for more than 20 parameters such as pressure and holding time. Built in process formula storage function, allowing for quick switching between pressing programs for different materials.
4. Modular structural design
The innovative quick release mold assembly structure can complete mold replacement within 5 minutes. The pressure head made of special steel has a service life of over 500000 times, significantly reducing maintenance costs.
Industry application expansion
1. Preparation of new energy materials
In the research and production of key materials such as positive and negative electrode materials and solid electrolytes for lithium batteries, ensuring the uniformity of powder forming density and improving battery performance consistency.
2. Ceramic manufacturing
Suitable for preform of structural ceramics such as alumina and silicon nitride, improving the density distribution of the green body and reducing sintering deformation through isostatic pressing process.
3. Powder metallurgy field
In processes such as hard alloy and metal injection molding (MIM), precision molding of complex shaped parts can be achieved with dimensional tolerances controlled within ± 0.05mm.
Future Development Trends
1. Intelligent upgrade
The equipment will integrate IoT modules to achieve remote monitoring and fault diagnosis, and cooperate with MES system to achieve production data traceability.
2. Development of large tonnage aircraft models
The industry is developing electric isostatic pressing equipment weighing over 500 tons to meet the forming needs of large-sized ceramic products and special alloys.
3. Multi functional integration
Future models may integrate online detection, automatic weighing, and other functions to form an integrated intelligent molding system.
