A METHOD AND APPARATUS FOR FORMING A MOULDING COMPRISING MAGNETIC PARTICLES

摘要

A method and apparatus is disclosed for forming a moulding. A material (23') comprising magnetic particles is injected into a mould (10) and a magnetic field is applied to at least a portion of the material (23') comprising magnetic particles so as to change the orientation and/or distribution the magnetic particles in the moulding material (23'). One or more further materials (24) may be injected into the mould (10) to form a multi-layered moulding. The further materials (24) may comprise magnetic particles.
