Moulding is a manufacturing process of shaping liquid or pliable raw material using a rigid frame called a mold.

• Types of moulding: injection moulding, blow moulding, compression moulding, rotational moulding, etc.

• Forging is a manufacturing process of shaping metal using compressive forces.

• LPDC stands for Low Pressure Die Casting, a casting process for producing metal parts.

• Materials used for moulding: plastic, rubber,

There are three types of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through direct contact between solids.

• Convection is the transfer of heat through the movement of fluids (liquids or gases).

• Radiation is the transfer of heat through electromagnetic waves.

• Examples: Conduction - touching a hot stove; Convection - boiling water; Radiation - feeling the warmth of the sun.

A boiler is a closed vessel used to generate steam or hot water for heating purposes. There are various types of boilers.

• Boilers are used in industries, power plants, and residential buildings.

The 5 engine part names are piston, cylinder, crankshaft, camshaft, and valve.

• Piston: Moves up and down inside the cylinder to compress the fuel-air mixture.

• Cylinder: Houses the piston and allows for the combustion process.

• Crankshaft: Converts the linear motion of the piston into rotational motion.

• Camshaft: Controls the opening and closing of the engine's valves.

• Valve: Regulates the flow of fuel-air mixture and exhaust

1st and 3rd angle methods are used in engineering drawings to represent the orientation of an object in 3D space.

• 1st angle method is commonly used in Europe and Asia, while 3rd angle method is used in North America.

• In 1st angle method, the object is placed in the first quadrant of the viewing plane, while in 3rd angle method, it is placed in the third quadrant.

• The symbol for 1st angle projection is a square with a dot ...read more
