veenu - factory visit

We went to visit 3 factories on the 21^st of April. These factories were small-scale units. It was a great learning experience where we saw to processes involved in the making of raw material to the final product. The learned the steps involved in procurement of raw material, making of different parts and assembling of these parts.

Aluminium Factory

This factory procures the scrap of waste pressure cooker, bus body, old coins and wire scrapes from the local market. Air blast oil fired furnace is used to melt the aluminium; here cover flux is added to segregate metal and its impurities. The molted metal in then pored into cast iron book moulds and then it goes through hot roller. Cold roller is used to stretch the thick metal sheet into the required thickness. Finally analing is carried out in a furnace in order to release the hardness of the metal sheet. These sheets of aluminium, after being cut into required shapes, are sold to the factories that make pressure cookers, utensils and bus body parts.

Wood Factory

This factory uses wood like saghoan, teek wood, sheesham, rose wood along with plywood and sun mica was used to make furniture. Their work is of high quality and precision is taken into account. Most products are exported and some are made for the local market also. As the machinery are very efficient so less manpower is required and the process is done faster. There were machine had sawdust suction which ensure better health of the workers. They made special blades for different range of styles in the furniture. Various electrical, pneumatic and mechanical machines were used in the whole process. Wide range of foldable furniture, and combination of various materials were used to create innovative furniture. Lots of experimentation was done in stone, metal and different leather.

Plastic Factory

This factory made pumps that are used in coolers. The plastic granules of dalerine which is a non-wearing plastic and which can’t be reused was used here. Nylon 66 which can be reused is also used here. The temperature used to melt the plastic is 80^oC. The process used was hand molding; they used different moulds for different products. The assembling of these parts was done at the same place. The other types of granules used were polycarbonates and ABS.
