subject: So Do Look For Aluminum Casting [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 . Nonstick Cookware 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..
Aluminum Casting has excellent mechanical, physical properties, it can have a variety of strength, hardness, toughness, matching overall performance, but also combines one or more special properties, such as wear resistance, high temperature and low temperature, corrosion-resistant and so on. Metal Halide Lamp 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. 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 Coach Bags, available audio, ultrasonic, eddy current, X-ray and -ray and other methods to check and judge.
Aluminum Casting casting choice principle: Aluminum Casting priority to the use sand casting, sand casting mainly lower cost than other casting methods, production process is simple, short production cycle. 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, Aluminum Casting can also be mass-piece casting Instrument valve.
