| dc.description.abstract |
The project is based on design, development and fabrication of small injection molding machine for the formation of small plastic articles in small-scale industries. The machine is capable of forming small plastic articles by injecting molten resins into a closed, cooled mold, where it solidifies to give the desired products. The machine is designed and constructed to work as a prototype for producing very small plastic /semi plastic components. Also, working drawings and materials selection is made based on calculations of the diameter of injection plunger, number of teeth required for the plunger rack and spur gear, the angular velocity, number of revolution, torque and power obtained from the electric motor and the leverage on the handle of the machine. The machine components are then assembled together. The result obtained from the test was satisfactory. |
