How do hockey helmets get constructed?

Answer 1

Plastic sections are moulded into shape and set. The wires making up the cage or face mask are bent into the right positions and welded together; their anchors are also attached this way.

The sections are bolted together, and padding is glued into them. Any straps are attached via buckles, which may be bolted onto the plastic part or welded onto the cage.

The cage is attached through its anchors to the plastic, and all straps and connections are checked off. Thus, a finished helmet.
