1. High casting quality: In the process of low pressure casting, the molten metal is filled and solidified under pressure, making the casting dense tissue and good air tightness. At the same time, due to the smooth filling process, the billowing, impact and splashing of the metal liquid are avoided, and the quality of the casting is further improved.

2. High dimensional accuracy of the casting: the metal liquid fills the cavity quickly under the action of pressure, which can accurately copy the mold surface. By controlling the casting temperature and the cooling rate of the liquid metal, the dimensional accuracy and shape of the casting can be precisely controlled.

3. Wide range of application: low pressure casting is suitable for a variety of casting materials, such as sand, lost wax, shell, graphite, semi-metal and metal. At the same time, low pressure casting is also suitable for a variety of casting alloys, including non-ferrous alloys, cast iron and cast steel.

4. Convenient production operation: the pouring system of low pressure casting is simple, which can reduce or eliminate the riser, and the metal liquid that has not yet solidified can flow back to the crucible, reducing the loss of the metal liquid. In addition, low pressure casting is easy to achieve mechanization and automation, improving production efficiency.

5. Casting surface clean: due to the metal liquid filling under pressure, can improve the flow of metal liquid, conducive to the formation of a clear outline, smooth surface of the casting.

6. High mechanical properties: the casting crystallizes and solidifies under pressure, can be fully supplemented, the casting has dense structure, good mechanical properties, such as tensile strength and hardness, etc., have been improved.

In summary, low pressure casting parts have the advantages of high quality, high precision, wide applicability, easy operation, high mechanical properties and surface smoothness, which make it widely used in aviation, aerospace, automotive, machinery manufacturing and other fields.

I. Design elements:

1. Geometry: The design must consider the feasibility of the casting process and avoid shapes that are too complex or difficult to fill.

2. Wall thickness: Appropriate wall thickness can ensure the structural strength and stability of the casting, while avoiding shrinkage holes, shrinkage and other defects.

3. Gating system design: Reasonable gating system design is crucial to ensure the smooth metal flow and filling integrity.

4. Die inclination: In order to release the mold smoothly, it is necessary to consider the die inclination, especially in complex shapes of castings.

The melting point and fluidity of the material are considered to ensure that the mold can be filled smoothly during the casting process.

Third, casting process:

Choose the right casting process, such as gravity casting, pressure casting, sand casting or metal casting, to meet the quality and production efficiency requirements of the casting.

Consider the temperature control, pouring speed, cooling speed and other factors in the casting process to ensure the quality and performance of the casting.

4. Mold design:

The mold design should consider the dimensional accuracy, surface quality and production efficiency of the casting.

Select the right mold material and structure to ensure the durability and stability of the mold.

V. Quality control:

Develop strict quality control standards, including material inspection, casting process monitoring, casting inspection, etc.

Adopt appropriate testing equipment and methods, such as X-ray testing, ultrasonic testing, mechanical properties testing, etc., to ensure that the quality of the casting meets the requirements.

Vi. Cost-effectiveness:

Consider the cost of custom castings, including material costs, processing costs, mold costs, etc.

Under the premise of meeting the quality requirements, we seek ways to reduce costs and improve the cost performance of customized castings.

7. Delivery time and after-sales service:

According to customer needs to determine the delivery time, and reasonable arrangement of production plan.

Provide perfect after-sales service, including technical support, maintenance services, etc., to ensure that customers get timely help in the process of use.

8. Environmental Protection and Sustainability:

Environmental requirements are considered in the customization process to reduce waste and pollutant emissions.

Choose materials that can be recycled and reused to improve resource efficiency.

In summary, custom aluminum alloy casting needs to consider design, material, process, mold, quality, cost, delivery time and environmental protection and other factors. By taking these factors into account, it is possible to ensure that the quality and performance of customized castings meet customer needs, while maximizing economic and social benefits.
