Aircraft Sales and Parts

Aircraft wings and dashboards are shaped in metal molds. These have to be 'greased', just like cake tins, before each molding process so that the plastic parts can be extracted at the end. A permanent coating has been designed to provide help in future. Baking a cake without greasing the tin is usually a disaster: The cake cannot be taken out in one piece. The same principle applies to the manufacture of fiber-reinforced plastic parts such as aircraft wings. Before the engineers can pour the mixture of resin, plastic and textile fibers into the metal mold, they have to apply four to six layers of release agent -- mostly by hand.
