It is the simplest method used to create thin films from solution using centrifugal force. By drop small amount of polymer solution (or chemical solution) onto spinning head (mold or surface), then spin the solution (rpm for few seconds or minutes), the centrifugal force (force used for rotating around the motor) will provide enough force to spread the solution droplet into thin film layers spreading out on top of the surface (mold).

What is gravity die casting?

It is process of making Alu. zinc component die. and material flows in die by Gravity force only no external pressure applied as Pressure Die Casting. Gravity casting is the liquid metal in the Earth's gravity into the casting process, also known as gravity pouring casting. The generalized gravity casting include sand casting, metal casting, investment casting, lost foam casting, clay mold casting; narrow-defined gravity casting refers to the metal casting. uses the force of gravity, to fill a permanent mold, or die, with molten material. It does not use the high-pressure method to form the casting. It will ensure that there will not be any clusters formed during this gravity casting process. The method has advantages like cost effective, good quality, and process control over other casting techniques.

What is the difference between gravity die casting and die casting?

Die casting is done by forcing molten metal under high pressure into a mold. Gravity die casting is a simpler method in which molten metal is poured into the mold rather than using force and high pressure. Gravity die casting is mostly used for only simple shapes, while die casting can be used for much more complex ones.
