Aluminum gravity die casting is a permanent mould casting process, where the molten metal is poured from a vessel or ladle into the mould. The mould cavity fills with no force other than gravity, filling can be controlled by tilting the die. Undercuts, and cavities can be incorporated into the component form with the use of sand cores. This process gives a better surface finish than sand casting as well as better mechanical properties, both due to rapid solidification. EZLEE places an emphasis on understanding the specifications and customer quality requirements, and established a whole process quality control system, which is certified to ISO9001:2008, to cover the critical quality control on site, including the raw material, initial samples, process dimensions, mechanical character, surface treatment, packing and delivery.
