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.
ans is none because top gate are used in very large casting due to erosion occur in this casting
You cannot design a full adder using only OR gates. You also need AND gates. Typically, this can be done with just NAND gates.
channels or runners that connect the sprue to the pattern or mold cavity
There are several types of fence gate designs available for installation, including single swing gates, double swing gates, sliding gates, and cantilever gates. Each design offers different benefits and features, so it's important to choose the one that best suits your needs and space requirements.
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.
Gates, watchtowers, and ditches were included in city wall designs for defense and security purposes. Gates allowed controlled access, watchtowers provided surveillance and defense, and ditches acted as barriers to deter attackers. These features helped protect the city and its inhabitants from potential threats.

Good casting design can prevent problems by ensuring proper placement of gates and risers to allow for proper filling of the mold, promoting smooth metal flow and reducing the chance of porosity or shrinkage defects. Designing the mold with appropriate draft angles and fillets can also help prevent issues like cracking or distortion during solidification. Additionally, selecting the right material and considering factors like cooling rates and part geometry can further prevent casting problems and ensure a successful outcome.
