Moulding sand is prepared by mixing suitable amount of clay and water. 2. Place the pattern on moulding board with its flat side on the board. 3. Place drag over board after giving a clay wash inside. 4. Sprinkle the pattern and moulding board with parting sand. 5. Allow the loose sand preferably through a
Moulding materials are used for making cope, drag and core parts. As it’s used for making structural part it has to be processed certain kind of characteristics. Most desirable 8 Moulding Materials property are discussed below, MOULDING MATERIALS PROPERTY:- 1. REFRACTORINESS:- It is the capability of the moulding sand material to withstand the high temperature
MIG and TIG Welding are one of the most commonly known welding method. In this article we find out some key differences between them. DIFFERENCE BETWEEN MIG AND TIG WELDING:- MIG WELDING TIG WELDING 1. it’s Full form- METAL INERT GAS WELDING. 1. it’s Full form- TUNGSTEN INERT GAS WELDING. 2. MIG welding uses consumable
A number of foundry tools and other equipment are used in foundry work, particularly in sand moulding for doing different kind of foundry operation. All of them are classified
What is pattern? A pattern may be defined as the replica of desired casting which when packed or embedded in a suitable moulding material with some extra modifications (i.e Different allowances, Spece for core prints) produces a cavity called mould. This cavity when filled with molten metal produces the desired casting after solidification of poured
