Munshi & co started business in 1914, making various types of dies and engraving work, and graduated to manufacturing high precision dies. The company in 1949 won a "gold medal" at the 8th indian industrial exhibition held in mumbai. Later it started manufacturing soap making machinery and also detergent machinery, based on its own r& d. It has a good record of exports of soap machinery to various countries. The company offers roll mills - industry. Special chilled casting rolls are employed which rotate in roller bearings. The rolls are interior cooled with water to percolate undesirable heating of the mass during operation. There is continuous water circulation system in all the rolls. The transfer of soap or detergent mass from one roll to the next is enabled by the differing roll speeds. The first roll gathers up the mass and squeezes it. The second roll runs faster than the first roll as a result of which the soap sticks as a film of adjustable thickness onto the second roll - the rolls possess an accurate manually actuated fine inter roll gap adjustment. The third roll runs faster than the second roll owing to the inter roll gap and cause an intensive grinding of the soap or detergent mass in small layer thickness. The inter roll-gap between the upper and lower roll can be adjusted manually. The capacity ranges from 20 kg/hr to 250 kg/hr and above. Rolling mills are usually three but four and five roll mills are also employed for these purposes. The drive is affected via an electric motor and spur gears, pulley and v-belts. Production rate varies with product type, film thickness, moisture content, etc. The capacity ranges from 500 kg/hr to 2000 kg/hr and above.
