internship in Butterfly Manufacturing Company Ltd from 15th November to 15th January (2
months). This internship report based on ‘’Industrial Manufacturing Management and
Maintenance System of BMCL’’.
As an engineer we need to have some ideas about operations management of BMCL which
will help us to make this report worthy. We spent our full internship with four departments.
Materials department, Production department, Quality department and Maintenance
department. We worked in materials, production and quality department for 1 month. And
another 1 month we worked only in maintenance department. As an EEE student we have to
stretch importance in maintenance department because this is our main objective. First one
month we learnt about company rules and regulation, how to materials brought for production
and where it’s stock, how to produce products, what kind of machine need to produce which
products, how to check quality of products, how a product suitable for a customer and finally
how to packaging outgoing all products from this company. Next one month we worked in
maintenance department. We learnt here utility maintenance and floor maintenance of this
company. During the utility maintenance we learnt about sub-station, sub-station equipment,
transformer, generator, air dryer, compressor and main distribution panel. During the floor
maintenance how to machine worked, automation system, hydraulic system, pneumatic
system, how to control motor in Conveyor line and last which machine need PLC. This is all
