Key factors affecting the performance of die-castings for new energy automobiles

The influence of material selection on the performance of die-casting parts for new energy automobiles

Material selection is one of the basic factors affecting the performance of die-casting parts for new energy automobiles. Die-casting parts for new energy automobiles usually need to have performance requirements such as high strength, low weight, corrosion resistance and high temperature resistance. Different types of alloy materials, such as aluminum alloys, magnesium alloys and zinc alloys, have different physical properties and chemical characteristics, so it is crucial to choose materials reasonably. Aluminum alloys are widely used in new energy automobiles for their good lightweight performance and corrosion resistance; magnesium alloys, although with low density, are relatively less used due to their cost and processing difficulty; zinc alloys are mainly used for small parts. The purity, composition ratio and microstructure of the material directly affect the strength, toughness and fatigue resistance of the die-casting. As the performance requirements of new energy automobiles for parts continue to increase, the selection of materials has become the key to optimizing the performance of die-casting parts. The addition of certain elements in the alloy, such as silicon and copper, can not only improve the mechanical properties, but also improve the wear resistance and oxidation resistance.

The influence of die-casting process parameters on performance

The die-casting process is another important factor affecting the performance of parts. Multiple parameters in the die-casting process, including injection pressure, injection speed, mold temperature, cooling rate, etc., directly affect the physical properties and surface quality of the final die-casting. Excessive injection pressure may cause mold damage, while too fast injection speed may cause uneven flow, affecting the density and surface quality of the die-casting. In addition, the control of mold temperature is crucial. Too high mold temperature may cause oxidation on the casting surface, while too low temperature may cause the metal to fail to completely fill the mold, causing defects. Cooling time is also a key factor. Uneven cooling may cause internal pores or cracks, and in severe cases may cause deformation. Therefore, regulating the die-casting process parameters to ensure that they operate within the optimal range is crucial to ensure the quality of new energy automobile die-castings.

Influence of mold design and manufacturing accuracy

Mold design not only determines the shape, size and surface quality of die-castings, but also affects production efficiency and the manufacturing cost of parts. Reasonable mold design can optimize the metal flow path, reduce local stress concentration, reduce the defect rate, and avoid product damage or deformation during use. For die castings of new energy automobiles, especially high-load bearing parts, the design of the mold needs to take into account the mechanical properties under extreme conditions, such as expansion under high temperature environment and stress distribution caused by temperature gradient. The manufacturing accuracy of the mold is equally important. High-precision mold manufacturing can ensure the dimensional consistency and shape accuracy of each die casting, reduce the later processing and finishing work, and improve production efficiency. With the introduction of high-precision CNC equipment, the mold manufacturing accuracy has been further improved, which directly improves the production quality of die castings.

Surface treatment technology improves the performance of die castings

Surface treatment technology is a key link to improve the corrosion resistance, wear resistance and aesthetics of die castings. In the production process of new energy automobiles, the surface of die castings often needs to withstand the challenges of high temperature, chemical media and harsh environment, so surface treatment becomes a key step to improve its durability.

With the increasing requirements for environmental protection and sustainable development, future surface treatment technology will develop in a more environmentally friendly and low-pollution direction.

The impact of structural design on performance

The die-casting parts of new energy automobiles are not only required to have high strength and durability, but also to be lightweight. Reasonable structural design can reduce the amount of materials and reduce the weight of the automobile body while meeting the strength and stiffness requirements, thereby achieving the goal of energy conservation and emission reduction. Structural design not only considers mechanical properties, but also comprehensively considers the product's use environment, assembly requirements and feasibility of production processes. For example, the battery pack and drive system of electric automobiles usually require die-castings to withstand greater pressure and vibration, so their structural design must have good impact resistance and fatigue resistance. Through finite element analysis technology, engineers can optimize the structure in the design stage and accurately predict the stress, thermal expansion and deformation problems that die-castings may encounter in actual work, thereby ensuring the long-term stable operation of parts.

The role of production environment and quality control

The control of production environment directly affects the quality of die castings. A clean production environment can effectively avoid undesirable phenomena such as bubbles and impurities on the surface of molds and castings due to contamination. Temperature and humidity control is also an important factor in ensuring the quality of die castings. Excessive temperature and humidity may cause deformation or dimensional instability of castings. Therefore, the temperature and humidity of the production workshop should be kept within an appropriate range. In terms of quality control, die castings of new energy automobiles usually need to pass multiple tests and inspections, including dimensional measurement, mechanical property testing, non-destructive testing, etc. With the advancement of science and technology, non-destructive testing technologies such as laser scanning and ultrasonic testing are gradually applied to die casting production, which can effectively discover and correct potential defects and ensure the high quality and long-term reliability of parts.

Summary of key factors affecting the performance of die castings for new energy automobiles

The performance of die castings for new energy automobiles not only depends on the selection of materials and process parameters, but also is affected by the comprehensive influence of mold design, surface treatment, structural design, production environment and other factors.
