The teacher demonstrates how to use the injection mold machine.
Students are to produce 2 injection molded parts from our pre-made molds and clean them up for final presentation.
A video about
injection molding is shown in class. An
injection mold making video is also shown so students understand the process and expense involved in mold making.
Finally, a short video about the production of Lego parts is shown (from the 50's and from the
modern age).
