Application fields and technical requirements of die castings for new energy vehicles

New energy vehicles include electric vehicles (EV), plug-in hybrid vehicles (PHEV) and hydrogen fuel cell vehicles, etc. The application fields of their die castings cover multiple key components, including body structure, chassis, power battery system and motor components. The following are several major application fields of die castings for new energy vehicles:

Body and chassis structure

In the design of new energy vehicles, lightweight and strength improvement of body and chassis are key technical requirements. The use of New Energy Automobile Die Castings die casting process can integrate multiple parts, reduce weight and improve the overall performance of the vehicle. Aluminum alloy and magnesium alloy materials are widely used in the manufacture of body structural parts and chassis brackets because they are not only strong but also have low density.

Using the high-precision aluminum alloy die casting machine of Ningbo Jinyao Machinery Co., Ltd., in conjunction with the parts produced by the CNC machining center, it is possible to manufacture high-strength, low-weight body frames and chassis brackets to meet the strict requirements of new energy vehicles for lightweight. At the same time, the castings are post-processed by precision cutting equipment to further improve the surface quality and dimensional accuracy of the parts.

Battery system and thermal management components

The battery system is the heart of new energy vehicles, and the structure and heat dissipation system of the battery pack are crucial to the performance of the vehicle. New Energy Automobile Die Castings play an important role in the production of battery packs and battery management systems. Through New Energy Automobile Die Castings, high-precision battery housings, heat sinks, battery separators and other components can be produced to meet the multiple needs of lightweight, strength and thermal management.

Ningbo Jinyao Machinery Co., Ltd. uses fully automatic deburring systems and precision machining equipment to ensure the smoothness and dimensional accuracy of the surface of battery system components, thereby improving the heat dissipation effect, extending battery life and improving the endurance of electric vehicles.

Motor components

The motor is the power source of new energy vehicles. The manufacturing of the motor requires high precision and high performance, especially in the production process of stators, rotors and housings. Die casting technology can efficiently manufacture various components of the motor to ensure its reliability and durability under high load and high temperature environments.

Ningbo Jinyao Machinery Co., Ltd. provides a variety of die casting machines from 280 tons to 2500 tons, which can meet the production needs of motor components of different specifications. During the production process, the company combines high-precision CNC milling machines and surface treatment equipment such as horizontal polishing and vibration grinding to ensure the smooth surface of each motor component and ensure the high efficiency and stability of the motor.

New Energy Automobile Die Castings" Production Process and Technical Advantages

The production of New Energy Automobile Die Castings requires not only high-precision die-casting machines, but also precise post-processing processes to ensure the quality of parts. Ningbo Jinyao Machinery Co., Ltd. has a complete production line and high-precision equipment to meet the strict requirements of new energy vehicle manufacturing for die-casting parts.

High-precision die-casting and efficient production

Ningbo Jinyao Machinery Co., Ltd. has introduced die-casting equipment from world-renowned brands, covering medium to large die-casting machines, which can meet the production needs of various new energy vehicle parts. Whether it is body structure parts, chassis brackets or battery pack shells, the company's die-casting equipment can provide precise casting results.

The company is also equipped with CNC milling machines and precision cutting equipment from Japan's Makino, Brother and the United States' Wheeler. These high-precision equipment ensures the machining accuracy of castings and ensures that the dimensional tolerance of each component meets the standards for new energy vehicle production.

Post-processing and surface treatment technology

The surface treatment of new energy vehicle die castings is crucial to their appearance, corrosion resistance and long-term performance. Ningbo Jinyao Machinery Co., Ltd. has a full range of surface treatment equipment, including hanging polishing, horizontal polishing and vibration grinding, which can meet the surface smoothness requirements of different types of castings.

Hanging polishing and horizontal polishing: used to improve the surface finish of aluminum alloy die castings and avoid defects in the appearance of the vehicle.
Vibration grinding: By removing burrs on the surface of the casting during the vibration grinding process, the overall surface quality and precision of the casting are improved.

This series of surface treatment processes not only improves the aesthetics of die castings, but also enhances their corrosion resistance and wear resistance, and is particularly suitable for the exterior and chassis components of electric vehicles.

Automation and flexible production line

In order to improve production efficiency, Ningbo Jinyao Machinery Co., Ltd. introduced a flexible automated deburring system and precision cutting equipment on the production line. The automated deburring system can automatically remove burrs and excess parts after casting production, avoiding the inefficiency and errors of manual deburring. At the same time, precision cutting and processing equipment can be customized according to different parts requirements, greatly improving the flexibility and efficiency of production.
