Material used for manufacturing chair is Polyethylene terephthalate also known as PET. It has good mechanical properties and good corrosion resistance of thermal radiations.

Process:

Plastic pellets are added in the hopper and is heated above its melting point. These are then sent in an injection molding machine. These are then pressed and squeezed into the mold (mold shown in Figure bellow) then they are separated to get to get the molded chair. These are then cleaned by removing the burr present on the part. After this sharp corners are removed and finishing operations are done on it to make it shine.
