What are the different types of gates provided in casting design?

There are five different gating systems provided in casting design. They are the horizontal gating system, vertical gating system, top gating system, bottom gating system and the middle gating system. The gates provide a way for the hot metal to flow.


What is gating ratio in casting?

Gating ratio is the ratio of sprue area to total runner area to total gating area. As : Ar :Ag


What are the functions by the gates in casting process?

Gate is the portion of the runner through which the molten metal enters the mold cavity. Depending on application, many types of gates are used in casting design. Parting gate is commonly used. The metal enters the mould at the parting plane when part of the casting is in the cope and part in the drag. Gate is specially, the point at which molten metal enters the casting cavity. A mould cavity must be filled with clean metal in a controlled manner to ensure smooth, uniform and complete filling, for the casting to be free of discontinuities, solid inclusions and voids. This can be achieved by a well-designed gating system. The first step involves selecting the type of gating system and the layout of gating channels, the orientation and position of sprue, runner and ingate. The most critical design decision is the ideal filling time, based on which the gating channels are designed.


What is the definition of gating factor?

Gating Factor refers to the key element of a series of interdependent tasks which has the ability to delay the whole. For Example: "The arrival of the last shipment of components will be the gating factor for us to be able to meet our on time delivery."


What does gating have to do with tomography?

Gating is the technique of synchronizing the motion of the heart with the images taken during tomography to eliminate blurring normally caused by the beating of the heart.

What are mechanical gated channels?

Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions to enter the cell.
