PS3 controller

Playstation 3 dual shock controller  

Not a lot of information out there about the manufacturing and actual plastics used, there must be a  Sony patent on the design. 
Outer shell made from HDPE (high density polyethylene) injection moulded in two parts. The front and back clip together and are screwed in place by 5 screws at the back of the controller.
