Application of non-standard precision low-pressure casting in the field of new energy
description1

Motor housing
The motor of new energy vehicles is the core power component, and the performance of its housing directly affects the operating efficiency and reliability of the motor. Yongkang Hantai Casting uses non-standard precision low-pressure casting technology to manufacture the motor housing, which has excellent thermal conductivity and can effectively dissipate the heat generated by the generator during operation, ensuring that the motor can still operate stably under high temperature conditions. At the same time, the motor housing has good mechanical strength and electromagnetic shielding performance, which prevents the influence of external electromagnetic interference on the motor control system and ensures the driving safety of the vehicle. Its precise size and smooth inner surface help optimize the heat dissipation channel and internal structure layout of the motor, and improve the overall performance of the motor.
For example, the motor housing we customized for a new energy vehicle brand has been rigorously tested. Under harsh working conditions such as high temperature and high speed, the temperature rise of the motor is controlled within a reasonable range. The motor efficiency is increased by [80]% compared to the housing manufactured using traditional casting technology, which significantly improves the vehicle's cruising range and power performance, and has been highly recognized by customers.

Battery Pack Housing
As the energy storage core of new energy vehicles, the battery pack housing not only needs to have high strength and good sealing to protect the internal battery module from external impact, dust and moisture, but also needs to have certain heat dissipation and insulation properties. Yongkang Hantai Casting's non-standard precision low-pressure casting process can manufacture battery pack housings with complex structures and high precision requirements. By accurately controlling the wall thickness and the distribution of reinforcing ribs, the mechanical properties of the housing are optimized, so that it can remain intact under various bumps and collision conditions during vehicle driving. At the same time, a special heat dissipation rib structure is designed on the surface of the housing, combined with the excellent thermal conductivity of the material, to achieve efficient heat dissipation of the battery pack and extend the battery life.
Compared with traditional processes, our battery pack shell also has significant advantages in lightweighting. While ensuring structural strength, the weight is reduced by [X]%, which helps to reduce the weight of the entire vehicle and improve the energy efficiency of the vehicle. In addition, by optimizing the casting process, a close fit between the shell and the battery module is achieved, which improves the space utilization of the battery pack and provides the possibility for the compact design of new energy vehicles.

Inverter shell
The inverter is a key component in new energy vehicles that converts direct current into alternating current. Its shell needs to have good heat dissipation performance and electromagnetic compatibility. Yongkang Hantai Casting's non-standard precision low-pressure casting inverter shell is made of aluminum alloy material. After special heat treatment process and surface treatment, it has high thermal conductivity and low thermal resistance. It can quickly dissipate the heat generated inside the inverter to the external environment, ensuring the temperature stability of the inverter when it is running at high power, thereby improving its conversion efficiency and reliability. At the same time, the electromagnetic shielding coating on the surface of the shell effectively prevents the leakage of electromagnetic interference and ensures the normal operation of the vehicle's electronic system.
In actual applications, the inverter housing we produced for a new energy vehicle company has increased the heat dissipation efficiency of the inverter by [X]%, reduced electromagnetic interference by [X] decibels, significantly improved the performance of the inverter, and provided strong support for the efficient power transmission and stable operation of new energy vehicles.

Solar tracking bracket components
In the solar photovoltaic power generation system, the tracking bracket can automatically adjust the angle according to the position of the sun to improve the power generation efficiency of the solar panel. Yongkang Hantai Casting's non-standard precision low-pressure casting components, such as the joint bearing seat and drive housing of the tracking bracket, have high precision and high reliability. These components can operate stably for a long time under complex outdoor environmental conditions, withstand erosion by natural factors such as wind, sand, rain, and ultraviolet rays, and ensure the flexible rotation and precise control of the tracking bracket. Its precise casting process ensures the dimensional accuracy and matching clearance of the components, making the movement of the tracking bracket smoother, reducing friction and wear, extending the service life of the equipment, and improving the overall power generation efficiency of the solar power generation system.
For example, in a large solar power station project, the failure rate of the tracking bracket casting parts we provided was far lower than the industry average after years of actual operation, and the power generation efficiency was improved by [X]%, which brought significant economic benefits to the power station owner and also contributed to the efficient use of solar energy.

Wind turbine parts
The parts of wind turbines, such as hubs, variable pitch bearing seats, gearbox housings, etc., have extremely high requirements for casting quality and performance. Yongkang Hantai Casting uses non-standard precision low-pressure casting technology to manufacture precision castings that meet the high strength and high fatigue life requirements of wind turbines. By optimizing the casting process parameters and alloy composition, the castings we produce have excellent mechanical properties and can maintain stable operation under complex wind field environments and long-term alternating loads. At the same time, the precise casting size reduces the amount of subsequent processing, reduces manufacturing costs, and improves production efficiency.
In the field of wind power, we have cooperated with many well-known wind power companies and provided them with high-quality parts. For example, the wind turbine hubs we produce have undergone rigorous fatigue testing and actual operation assessments, and their fatigue life has reached more than [X] times the design requirements, effectively ensuring the safe and stable operation of wind turbines and providing reliable support for the development of the wind energy industry.
