mplementation of the project “Design and manufacture of plastic molds
(Design and manufacture of plastic molds 6 kinds of spoon products)” and set up process
machining technology of molds. We finished with full content requirements. Through
the project, we not only practice the knowledge we learned in basic and specialized
subjects but also directly interact with new knowledge on mold processing technology,
advance machining such as CNC. And non-traditional methods such as Etching and
Rapid Prototyping.
Finally, we would like to thank Mr. Pham Son Minh for helping us complete our
graduation project. We thank the board teachers and all teachers at the school who led to
teach us the knowledge of machine manufacturing technology, which helps we can
complete the project on time, on duty and the plan is assigned.
