تخصيص علبة التروس للسيارات المصنوعة من الألومنيوم المصبوب

Aluminum die-cast automotive transmission cases have many details to consider during the design and production process, which directly affect their performance and longevity.

1. اختيار المواد:

1،Aluminum alloy composition: commonly used aluminum alloys include  ADC12، A380، A383 etc., which have good mechanical properties and castability. The composition of the alloy affects the strength, hardness and corrosion resistance of the shell.

2،Alloy treatment: Heat treatment, such as aging, is usually required to enhance the strength and hardness of aluminum alloys.
2. Die casting process:

1،Die design: Accurate die design is critical to the quality of aluminum alloy die castings. The mold must be able to withstand high temperatures and pressures, while ensuring the accuracy and surface finish of the castings.

2،Casting process control: This includes temperature control of the molten aluminum alloy, injection speed and pressure control, etc. to ensure that the castings are dense and free of porosity.
3. التصميم الإنشائي:

1،Strength and stiffness: the case design needs to take into account the mechanical loads that the transmission is subjected to when it is working, so it is necessary to design reasonable reinforcing bars and reinforcement areas.

2،Heat dissipation design: Aluminum alloy has better thermal conductivity, but the design still needs to consider the layout of heat sinks and ventilation holes to ensure that the transmission can effectively dissipate heat when running at high temperatures.
4. surface treatment:

1، Anti-corrosion treatments: aluminum alloy surfaces are often anodized to improve corrosion and wear resistance.

2،Coatings: Spraying or other surface treatments are sometimes applied to enhance appearance and durability.
5. Accuracy requirements:

1، Dimensional Accuracy: Die castings require a high degree of accuracy to ensure that the components of the transmission fit together precisely. Dimensional tolerance control is critical to assembly and operational performance.

2، Surface finish: A smooth surface reduces friction and wear and improves the service life of the parts.

6. Post-treatment processes:

1،Machining: Some die castings require machining after casting, such as drilling, cutting and trimming, to meet final assembly requirements.

2،Quality inspection: This includes non-destructive testing (e.g. X-ray inspection) and mechanical property testing to ensure that each casting meets design requirements and safety standards.
By carefully designing and controlling these details, you can ensure that aluminum die-cast transmission cases will perform well in automotive applications, providing reliable performance and long service life.
