Why build the Plastic Shredder?
The function of the shredder is to crush recycled plastic into tiny pieces, which will be then placed into the compressor, injection molding machine and or extruder. The plastic is crushed because this makes it easier to melt and form, since a greater surface area of the plastic is exposed to heat.

Building the Shredder
Outside the High School Design lab, we have collected different types of plastic, which will be crushed into tiny pieces by the shredder. The crushed plastic will then be placed inside a mould, added to the compressor.
This process involved grouping the different parts of the shredder so that they may be assembled easily
In this picture, we are assembling the shredder. This process involved fixing the parts in their designated positions so that they may be welded together.
Our team working on the 3 phase electrics of the shredder! The purpose of developing the electrics is so that the rotation of the shredder may be alternated from clockwise and anti-clockwise.
A lift's motor, with an rpm of 90, that will be used to provide the power in rotating the grinders of the shredder. Although it may look old, it is extremely strong and will work in the desired way.
The image to the left involved fixing the motor to the shredder. Both parts are sitting on a reinforced steel frame.
The final product! Shredded and washed PET flakes drying in the sun.
