New energy vehicles are an important development direction of the global automobile industry. Their environmental protection and high efficiency are gradually changing the face of the traditional automobile manufacturing industry. In the manufacturing process of new energy vehicles, die-casting technology plays a vital role. This article will conduct an in-depth discussion on the application of die-casting machines in new energy vehicle manufacturing.

1. Basic principles of die casting machine

A die casting machine is a pressure casting equipment for metal or non-metallic materials. It injects molten metal or alloy liquid into the mold at high speed through high pressure, and after cooling and solidification, it forms parts or components of various shapes, such as automobile engine cases, wheel hubs, battery packs, etc.

The working principle of the die casting machine can be divided into four basic steps:

Pouring: Molten metal is injected into the mold under high pressure;
Filling: The molten metal flows and cools in the mold until it solidifies to form the part;
Demolding: The solidified parts are taken out of the mold;
Cleanup: Clean the mold in preparation for the next pour.

2. Application of die-casting machines in new energy vehicle manufacturing

In new energy vehicle manufacturing, die-casting machines are mainly used in the following aspects:

Body structure and components
The body structures and components of new energy vehicles usually use high-strength, lightweight aluminum alloy materials, which places higher requirements on die-casting technology. For example, the body structure of new energy vehicles needs to withstand greater loads and impacts, so it has higher requirements for the strength and toughness of aluminum alloy materials. In addition, aluminum alloy materials have poor fluidity and require high-pressure injection to form complete parts. Die-casting machines are able to meet these requirements and produce high-quality aluminum body structures and components.

battery pack
The battery pack of a new energy vehicle is an important component, and its safety and performance directly affect the performance and life of the vehicle. The battery pack usually contains a large number of lithium-ion battery cells, which need to be made into battery cases of various shapes and sizes through a die-casting process to adapt to different power needs and safety performance requirements. The die-casting machine can precisely control the shape and size of the battery pack to ensure its safety and performance.

Motor and electronic control system
The motors and electronic control systems of new energy vehicles also require the use of a large number of die-cast parts, such as motor casings, electronic control boxes, sensor casings, etc. These parts need to be manufactured under high precision and complexity requirements, and die-casting machines have excellent molding accuracy and production efficiency to meet these requirements.

3. Advantages of die-casting machines in new energy vehicle manufacturing

The application of die-casting machines in new energy vehicle manufacturing has the following advantages:

high efficiency
Compared with traditional stamping, machining and other processes, die-casting machines have higher production efficiency. On the one hand, the die-casting machine has a fast molding speed, which can greatly shorten the product development cycle; on the other hand, the die-casting machine can reduce the later machining and assembly links, further improving work efficiency.

High precision
The die-casting machine can achieve high-precision molding, especially for parts with complex shapes and high-precision requirements. This is particularly important for the manufacturing of new energy vehicles, because each component of a new energy vehicle needs to strictly comply with design requirements to ensure the performance and safety of the vehicle.

Save materials
Compared with traditional casting processes, die-casting processes can save materials more effectively. Due to the poor fluidity of aluminum alloy materials, traditional casting processes often require the removal of a large amount of remaining material, while the die-casting process can reduce this waste to a great extent. In addition, the die-casting process can also achieve mass production, further reducing the material cost per unit product.

4. Conclusion

The development of new energy vehicles provides a broad application space for die-casting technology. The application of die-casting machines in new energy vehicle manufacturing not only improves production efficiency, but also improves product quality and precision, effectively promoting the development of the new energy vehicle industry. However, as new energy vehicle technology continues to advance, the demand for die-casting technology will continue to increase. Therefore, future research should pay more attention to improving the intelligence and flexibility of die-casting machines to meet more diverse and personalized production needs.
