subject: Aluminum Casting Product Knowledge [print this page] Aluminum Casting quality of the performance of mechanical products have a significant impact. For example, the machine Aluminum Casting wear resistance and dimensional stability, directly affect the accuracy of machine tools to maintain life; all kinds of pump impeller, housing, and hydraulic pressure cavity size, profile accuracy and surface roughness, a direct impact pump and hydraulic system efficiency, energy consumption and air loss of development; internal combustion engine cylinder block, cylinder head, cylinder liner, piston rings, exhaust and other Aluminum Casting of strength and resistance to thermal shock of cold shock, directly affecting the engine's working life .
Enamelware weight and size range is very wide, only a few grams of the lightest weight, most weight up to 400 tons, the thinnest wall thickness of 0.5 mm and the thickest of more than 1 meter in length may be a few millimeters to 10 meters can be used to meet the requirements of different industrial sectors. Foundry, Aluminum Casting to the quality of the control and inspection. First developed from the raw materials, auxiliary materials to each specific product process control and inspection codes and technical requirements. On each process strictly according to rules and technical requirements of process control and inspection. Finally Finished Aluminum Casting for quality inspection. Detection methods should be equipped with reasonable and appropriate test personnel. The general appearance of the Aluminum Casting quality specimens can be compared to determine the Aluminum Casting surface roughness; surface cracks can be subtle shading, and magnetic method check. Internal quality of the Aluminum Casting, available audio, ultrasonic, eddy current, X-ray and -ray and other methods to check and Coach Bags.
Metal Halide Lamp casting method is commonly used resin sand casting, followed by special casting methods, such as: metal casting, investment casting, plaster casting. The sand casting sand can be divided into clay, organic binder sand, resin from the hard sand, lost foam, etc.. When the wet type can not meet the requirements and then consider the use of clay, sand is dry sand, dry sand or other sand. Green sand mold castings from a few kilograms of weight can be up to tens of kilograms, while the production of dry clay can weigh hundreds of tons of castings. Aluminum Casting casting and production methods should be suited to volume, low pressure casting, die casting, centrifugal casting and other casting methods, equipment and tooling for the price of expensive, so only suitable for mass production.
