This document summarizes the process of mould making. It defines a mould as a hollowed-out block used to shape liquid materials like plastic, glass, or metal. The key steps in making a simple mould are: 1) placing the drag half of the pattern on a moulding board, 2) adding pins and parting sand, 3) cutting funnels for runners and risers, 4) applying a coating, 5) drying or blowing air to prepare the mould, and 6) closing the cope over the drag to complete the mould for pouring. Moulds are used across industries to manufacture objects through casting.

2. What is Mould......?
• Moulding is the process of manufacturing by
shaping liquid using a rigid frame called a mould.
• A mould is a hollowed-out block that is filled with a
liquid or pliable material such as plastic, glass,
metal, or ceramic raw material.
• A mould is the counterpart to a cast.

3. • The manufacturer who makes the molds is called
the mouldmaker.
• A release agent is typically used to make removal
of the hardened/set substance from the mould
easier.
• This is generally only used for larger and more
valuable objects.

4. Processes of mould
The various stages in making a simple mould :-
1. Place to drag half of the pattern on the molding board with
parting surface in contact with the board.

5. 2) Place the Drag in position on the board with pins
pointing downwards.
3) Cut off excess send off the mould using a strike off
bar.
4) Sprinkle parting send over the surface uniformly.
5) Place the runner and riser pins in proper position
depending on the getting in risering system decided.
5) Cut funnels around the runner and riser pins using a
gate cutter.
6)Remove the runner and riser pins.

6. 7) Dust the surface of the mould with a coating material.
8) Dry to mould in case of dry sand moulding.
9) Remove any loose or burnt send by blowing
compressed air if it is a bried mould.
11) Close the cop over the drag.
12) Weight or clamp the cope and drag the mould is now
ready for pouring.
