Low pressure and gravity casting are two similar casting processes used to manufacture metal parts and components. Each casting method has its own benefits and drawbacks, so it is important to understand the differences between them.
Low pressure casting is a process in which molten metal is injected into a mold at a low pressure, usually less than 10 pounds per square inch. The low pressure results in less force being applied as the molten metal is pushed into the mold, allowing for cleaner, smoother surfaces with fewer surface defects. Low pressure casting also requires less energy than other casting methods, and allows for greater control of the speed and volume of the molten metal being injected into the mold.
Gravity casting, on the other hand, utilizes gravity to fill the mold with the molten metal. This process is done in an open mold, usually with a ceramic core, into which the molten metal is poured. The core holds the shape of the part as the metal cools and solidifies. The downsides to this process are that because it relies entirely on gravity, the molten metal takes more time to fill the mold, and the surface finish of the part may not be as smooth as in low pressure casting.
In summary, both low pressure and gravity casting have their advantages and drawbacks. Gravity casting is a slower process and results in rougher surfaces, while low pressure casting is much faster and produces parts with superior surfaces. Companies should decide which casting process is the best fit based on the desired output and their budget.
1) Material Purchase Control: Our Material are imported from Malaysia, Thailand ect. Those country specializing in better rubber.

The wheels come in 17 20 inch sizes, made from A356.2 material with PCD options of 6X139.7/6X135. The MOQ is 80PCS, packaged in Brown Carton/White Carton, backed by a 3 Years warranty.
We provide LOGO customizing (Milled Letters and Word) on wheels, Center caps and Carton LOGO customizing, and requested finishing. We can manufacture using forged, Flow forming, and Lower pressure casting processes.
We provide timely per-sale and after-sale service. Before sample or mass production orders are placed, all details are checked and confirmed with customers. We accept sample orders for testing first, and offer a free sample policy when placing an order with us.
Gravity casting relies on gravity in an open mold, taking more time and resulting in rougher surfaces. Low pressure casting injects molten metal under low pressure (less than 10 psi), using less energy, offering faster production, and producing cleaner, smoother surfaces with fewer defects.
