What are the functions of pattern?
Functions of Pattern: (i) A pattern is essential for the production of any metal or alloy casting. (ii) A pattern is used to produce the cavity in the moulding sand for pouring the molten-metal. (iii) A properly manufactured pattern reduces the overall cost of casting.
What is pattern and types of pattern?
Types of Patterns Patterns are made of wood, metal, ceramic, or hard plastics and vary in complexity. A single piece pattern, or loose pattern, is the simplest. … Match plate patterns are patterns with the top and bottom parts of the pattern, also known as the cope and drag portions, mounted on opposite sides of a board.
What is difference between pattern and casting?
Casting is the process of pouring liquid metal into a mold, where it cools and solidifies. … Patterns are a model for the object to be cast. A pattern makes an impression on the mold, liquid metal is poured into the mold, and the metal solidifies in the shape of the original pattern.
