<p>The mixing chamber is surrounded by a bypass arrangement. Each constituent is fed through channels into the mixing chamber. When the mix is ready (a) it flows out directly into the mould and a plunger passes through to the bottom of the chamber, removing any residual resin and forming part of the moulding surface, (b) supply of each constituent is diverted through the bypass back via return channels to the source.</p> |
