Among the current metal processing technologies, there is a fast-developing special casting method that is pressure casting. The casting process is to quickly fill the molten metal into the mold under high pressure and high speed, and crystallize and solidify under high pressure to form a casting. The main characteristics of aluminum die castings are high pressure and fast speed. OEM Aluminum Die Castings can be made into processing parts such as auto parts, engine parts, power parts, construction parts, and decorative parts.
The difference between aluminum die casting and casting
Casting refers to a process in which a material melts into a liquid state at a high temperature to make it flowable. Then inject it into the mold cavity (the cavity is generally sand and metal, etc.), enter the set cavity and then cool to form. However, the surface roughness of such die castings is generally very low, and most of them are used as blanks, and rough machining and finishing are required separately, so cast iron will be used as a kind of casting material.
Because the metal copper, zinc, aluminum and aluminum alloy have good fluidity and plasticity, and the casting process is carried out on a pressure die casting machine, aluminum die castings can be made into various more complex shapes, and can also be made into higher The precision and smoothness.
In this way, the processing volume of castings and the casting allowance of metal copper, zinc, aluminum or aluminum alloy can be greatly reduced. It not only saves electricity, metal materials, but also saves labor costs. But copper, zinc, aluminum and aluminum alloys have excellent thermal conductivity, small specific gravity, manufacturability, and survivability. Therefore, die castings are widely used in various industries, such as automobile manufacturing, internal combustion engine manufacturing, motorcycle manufacturing, motor manufacturing, transmission machinery manufacturing, precision instrumentation, landscaping, power construction, etc.
Temperature will play a vital role in the production of each product, and aluminum alloy die castings are no exception. It will not only affect the quality of the mold, but also affect the service life of the product. The control of temperature is the control of surface heat treatment. In the die-casting mold processing technology, only when the temperature is stable, the quality of the forming mold will be the best, and the obtained surface will be relatively smoother.
Aluminum die castings play an extremely important role in machining. When purchasing, be careful not to buy defective aluminum die castings. If you buy it, remember to repair it in time to ensure that the entire machine is in good condition.
The above are all the differences between OEM Aluminum Enclosure and castings.
