Permanent Mold (Gravity) Castings
Based in Guanzhou, China, ChinaSavvy is a high quality permanent mold castings supplier and molding specialist. Our dedicated team endeavors to not only deliver quality castings, but an unsurpassed service at affordable prices.
Our world class machinery and highly experienced team casts parts ranging from 50 grams to 70 kilograms with good dimensional repeatability and little need for secondary finishing operations.
This casting process find applications in a number of industries, ranging to include the automotive industry, the electrical industry as well as the architectural industry.
In copper permanent mould casting, yellow brasses, high conductivity coppers and engineering alloys are used to produce various parts and components ranging from decorative faucets and sanitary fittings, to water pump impellers and cutout hardware.
Other component manufactured includes engine components, gears, wheels, insulating flanges, brackets for the textile industry, hand levers, filters for the petroleum industry, valve bodies for the electrical industry, light domes for general industries and electrical housing components, to name but a few examples.
Why Choose Permanent Mould Casting?
This particular casting process has its set of advantages and limitations, but is a popular casting process because it is capable of producing parts that are more complex than those parts produced by sand casting.
Another great reason for choosing this process is that the molds produced are reusable, it is a medium cost process (though set-up cost and tooling is high) and delivers parts that exhibit uniform mechanical properties.
Capable of delivering a finer surface finish than sand casting can, permanent mold castings also exhibit a better ductility than parts produced through die casting.
The Gravity Die Casting Process / Permanent Mold Casting Process
Gravity die casting, also known as permanent mold casting, is a metal casting process in which metal (usually steel or cast iron) is used as a mold material. The mold itself is usually in two halves and clamped together before pouring.
Cores, usually made from iron, steel or sand, is inserted before the two halves are clamped together. Before pouring can begin, the interior walls of the mold is coated with a refractory material and pre-heated.
Metals that can be permanent mold casted is poured, either directly or by tilting the mold into a vertical position, into the mold in molten or liquid form without the use of pressure.
The casting process consists of mold preparation, mold assembly, pouring, cooling, opening of the mold and trimming. For more detailed information on the process and its variations, please visit our Permanent Mold Casting Process page.
