Don’t let the basic design of the o-ring be fool your eyes! It is a huge undertaking to manufacture one of these small rubber rings and careful precision is put in each. The volume of o rings made every day by PPE Precision Polymer Engineering Ltd. Precision Polymer Engineering Ltd, is impressive in the best way possible. There are many steps involved creating custom polyurethane or neoprene o rings. Inside an o-ring factory can be seen in this video made by PPE.

It is no doubt that the method shown is amazing to watch. The materials are first mixed in a milling machine. It’s then extruded from a machine similar to an extruder for pasta. It is then moulded by a press, and then delivered to an mechanic or engineer that requires it. It’s fascinating to witness the creation of tiny rubber rings. But greater when you consider larger ones! They require more attention and care, being ran through a buffer machine. Production of rubber is both profitable and beautiful to observe.
