From June 28 to 29, 2023, the 4th New Energy Engineering and Industrial Development Conference was grandly held in Changzhou. The theme of this conference is "Intelligent Manufacturing of New Energy and Going Global with Industrial Chains". MEST, as a Chinese fluid application expert, was invited to attend and discuss the development prospects of the new energy industry chain with all parties in the industry. At the same time, MEST's precision dispensing, bonding, surface coating, fixed-point potting and other fluid application solutions also attracted people on site to stop and watch.

This time, MEST displayed products such as dual-aisle screw valve MEST-FD2000, single-aisle screw valve MEST-F2000, high-viscosity screw valve MEST-F1000, piston injection valve MEST-P20, gear injection valve MEST-GP30, etc. As well as customized products and solutions for the new energy automobile industry, many R&D and production engineering technicians from automobile OEMs and battery motor manufacturers have come to inquire and pay attention. MEST's products and technologies can be recognized by everyone and brings us greater confidence.

According to data from the Gasgoo Automotive Research Institute, the rapid development of new energy vehicles will drive high growth in demand for vehicle controllers, motor controllers, battery management systems and other related automotive electronics. The overall development of the new energy vehicle industry chain is on an upward trend and the market is improving. However, it should also be noted that the expansion of the production capacity of the three-electric system still faces the problem of bubbles in potting materials that reduce the yield rate. Vacuum potting technology is urgently needed to solve this pain point. .

Why is vacuum material preparation/vacuum pottting technology so important?

In the battery pack of new energy vehicles, in order to ensure the safety and stability of the battery, it is necessary to use vacuum preparation and potting technology to coat and bond the battery. In addition, in order to ensure the normal operation of the electric drive system, it needs to be heat dissipated and sealed. The G280 vacuum pail feeding system independently developed and produced by MEST presses the high thermal conductivity glue that has been degassed on the surface into every corner for heat dissipation, and seals and fills all parts of the electric drive system to prevent dust from entering the system.

In new energy vehicle motors, through vacuum potting technology, the inside and outside of the stator coil can be completely covered with heat-dissipating and insulating glue. The wires of the coil are protected by glue, thereby improving the thermal conductivity and insulation of the stator. , reduce friction loss, avoid instantaneous breakdown of high-voltage coils, and ensure the accuracy and stability of the motor stator.

Choosing the vacuum filling system independently developed by MEST can ensure a fully sealed vacuum environment from material preparation to feeding and filling to avoid the generation of bubbles.

The vacuum preparation&feeding system MEST-G380 performs glue pre-processing actions such as heating, stirring, and circulation within the vacuum pipeline. It can ensure a vacuum environment and isolate air during glue preparation and pressurized supply. The MEST-GV series of vacuum injection stations strictly ensures the vacuum operating environment. The glue is placed in the vacuum, and the stacked three-axis sends the glue to the piston injection valve MEST-P20 for high-precision dispensing operations to ensure product potting with bubble-free and ensuring product quality.

As an expert in fluid applications in China, MEST actively expands in-depth cooperation with automobile companies and has been recognized and trusted by more and more customers. In the future, MEST will continue to adhere to the vision of "intelligent exploration and promote the reform of the dispensing industry", continue to increase investment in the research and development of dispensing products, and provide customers with better products and services.

In the process of globalizing Chinese brands and entering the overseas new energy industry market, we will make full use of our own technological advantages to inject strong impetus into the high-quality development of the industry and accelerate the intelligentization process in the dispensing field. We will be like a ship that breaks the waves. Move forward courageously, constantly explore new markets, and win more respect and honor for Chinese manufacturing and Chinese brands.
