Quiz on Pattern

Here is the quiz for you:

Overview

A pattern is the replica of the object to be procured by Casting. Casting is a manufacturing process by which you can create the products with the help of hot liquid molten material.

The entire casting process includes: pattern or core making, moulding, melting of the material, fettling and finishing.

There are different types of patterns: solid or single piece pattern, split or two-piece pattern, multipiece pattern, match plate pattern, gated pattern, skeleton pattern, sweep pattern, pattern with loose pieces,cope and drag pattern,follow board pattern.
