The correct answer is option 'A': 3 5 2 1
Explanation:
To match the equipment with their respective functions, let's go through each option:
A. Hot chamber machine: This equipment is used for die casting. Die casting is a manufacturing process in which molten metal is injected into a die cavity under high pressure. The hot chamber machine is specifically designed for die casting with low melting point metals such as zinc, tin, and lead. So, the function of the hot chamber machine is die casting.
B. Muller: A muller is a machine used for mixing. In the context of mechanical engineering, a muller is commonly used in foundries for mixing sand and other materials used in the process of molding and core making. So, the function of the muller is mixing.
C. Dielectric baker: Dielectric refers to a nonconducting material or substance. A dielectric baker is an equipment used for annealing non-conductive materials. Annealing is a heat treatment process that involves heating a material to a specific temperature and then cooling it slowly to make it softer and more ductile. Dielectric bakers are commonly used for annealing plastic components or other non-metallic materials. So, the function of the dielectric baker is annealing.
D. Sand blasting: Sand blasting is a process used for cleaning or surface preparation. It involves propelling fine particles at high velocity to clean, etch, or roughen a surface. Sand blasting is commonly used in various industries including automotive, aerospace, and construction for tasks such as removing rust, paint, or contaminants from surfaces. So, the function of sand blasting is cleaning.
Based on the above explanations, the correct matching of List-I (Equipment) with List-II (Functions) is:
- Hot chamber machine: Die casting (3)
- Muller: Mixing (5)
- Dielectric baker: Annealing (2)
- Sand blasting: Cleaning (1)
Therefore, the correct answer is option 'A': 3 5 2 1.
