<p>A infusion in-mould helmet is disclosed. One side of a plastic sheet that is not resistant to high temperatures is attached with a protective tape that can withstand high temperatures, followed by printing, plastic removal, edge cutting, and hole drilling, to form an outer helmet. The outer helmet and a pre-formed inner helmet are disposed together in a molding machine to render an integrally formed sports helmet at lower pressure, lower temperature, and shorter time.</p> |
