| Summary: | This thesis is a project of design and fabrication of Small Scale Extrusion
Machine. In development the machine, the principle of extrusion process need to study
and understand to determine the components of the machine. Extrusion process is another
method to form and shape metals and plastics beside the other process such as injection
molding, blow molding and rotational molding.
The machine is designed to extrude raw materials such as plasticine and powder
in certain shape where screw will rotate to force the raw material from feed hopper to
shape-forming die. Design process start after know the functional of the components and
the conceptual design of the machine. During design phase, the shapes and dimensions
components will follow the guideline given by conceptual design.
After designing completed, the suitable materials is selected to fabricate the
components. Many machines are used to fabricate the components that drill, lathe,
milling and rapid prototyping machine. The machines used depend on the components to
fabricate and the materials used. All components are assembled after fabrication
completed to run extrusion machine by using motor. First run will evaluate the extrusion
machine performance. Improvement and modification need to be done to the design if
components are not functioning properly and effectively. Extrusion machine will run
again until the performance is satisfied.
