PET Fusing Machine

Previous Next

The design of the prototype is based on three stages which transform PET (polyethylene terephthalate) into cotton fibers, which can have different applications, including packing stuffing, stuffed toys, pillows, or synthetic thread.

The design moves around three important stages of transformation:

The first is the ignition of PET in small precut flakes, (between 5 and 7 mm2) by the hopper which is responsible for feeding a screw that is housed in a jacket (cast iron) at high temperature and is responsible for Transform the PET from solid to liquid phase.

The second stage presents a centrifugation of the liquid material through a saucer that is perforated symmetrically, and is responsible for passing the material from liquid form to semi-solid but in the form of small threads of plastic material, which is thrown to the walls of the equipment and Falls in the form of cotton.

The third stage is the transportation and complete solidification of the fibers emitted by the centrifugation system, so that at the end of the conveyor belts an operator can pack the product obtained.

As an advantage is the low cost in the acquisition of raw material due to the use of recycled PET pellets in a way that is easy to get in recycling centers, and even in city landfills.
At present there are processes used for the transformation of this material, however the implementation of this prototype could contribute to new small companies the opportunity to collaborate in the transformation of the plastic and to put in the market the product at low cost.
The environmental impact would occur with the high trasform trash (PET) in usable synthetic fibers introduced back to the market what in time was trash.

Beforehand I thank you that you are reading this short summary, I hope I could explain more concretely.
I appreciate the appreciable time taken to read it, and I would appreciate more, an opinion to help me improve.
