During the formation of cast aluminum parts, it is easy to produce internal loose, pores, and pores. These defective castings are removed after being processed by the surface and exposed the internal tissue defects.For car cast aluminum parts with sealing requirements, such as cylinder body, cylinder head, air intake manifold, brake valve body, etc., when performing pressure -resistant sealing tests, the presence of defect micro -pores will cause a large amount of leakage of the sealing medium to cause a lotThreading, and these defects are often found to be found after processing, causing severe waves in working hours, raw materials and energy.

Technical requirements for cast aluminum parts
Technical requirements: 1. The thickness of the product is uniform, and the difference in wall thickness cannot be too large.And the thickness should not be too thick (the phenomenon of bubbles and sand holes will be more) or too thin (poor filling, difficulty in molding).The thickness is determined according to the area of ??the products die-casting area.The minimum 0.8mm and the maximum 6mm.The product is too thin or the die -casting deformation is seriously enhanced.2. Some holes with high positioning holes and high accuracy. Die casting cannot be completely formed. It can only be made of pits first, and then processed.3. Do not have sharp corners as much as possible, generally the rounded corner of R1.0.4. The product should have a decarcal slope in the direction of the mold opening.The outer mold is generally 1 °, and the inner extract is 2-3 ° to facilitate the release of the mold.
Price of aluminum parts
Generally, there is very little weight according to the weight, because the small pieces of small pieces are not cost-effective, and the large parts of the automotive parts are a little more weight. Generally, it is 35-45 yuan per kilogram.There are more tonnage fees for Taiwan. For example, a 200 -ton of 2 yuan, a complex product with a slider or a heavy weight, and then add points appropriately.
