What is the difference between injection, vac formed, resin and mixed media?

Injection Moulded - Hot liquid plastic is injected at high pressure into a steel or resin mould. As used by the major firms in this business. This is mass production which usually results in the lowest retail price.

Resin Moulded - A mixture of 2 different chemical liquids which are mixed together and poured into a rubber mould. These kits may be hand made and the moulds usually only last for about 30 models before they have to be remade. Production is slow and resin is expensive, so resin kits and accessories are not cheap but this method does allow less well known aircraft to be produced. Aircraft that major manufacturers could not consider producing.

Vacform Moulding - A resin mould is made and then pushed into a sheet of heated plastic. The vacuum pump is turned on and the plastic is sucked down into the mould. All parts are in the sheet and then have to cut out and then sanded down until the parts look as they would if they had been injection moulded. There are fewer and fewer kits being made this way but we will continue to stock them while we can

Multi Media. Made from a mixture of materials. A typical kit might have a vac formed fuselage, resin wings and engines with small parts such as the undercarriage in white metal. Different manufacturers can vary this mix slightly

All methods allow superb detail to be achieved. The better the original master and mould, the better the parts will be.
