  • Rotational molding machine and method
    Patent number: 8562333
    Abstract: A molding machine apparatus and method for the production of thermoplastic skins or shells by means of what is generally known as rotational or slush molding. The tooling is heated uniformly, rapidly and efficiently by means of high velocity, hot air streams directed at the tooling which create turbulent flow on the surface of the tooling. The air stream is accelerated by means of adjustable nozzles and the air is circulated in the mold by means of a centrifugal fan.
    Type: Grant

  • Moulding method using microwaves
    Publication number: 20100038828
    Abstract: A method of moulding products made of expanded polymer beads using steam. The steam is generated by introducing a quantity of water into a mould that is capable of being pressurized. Steam is created by way of exposing the mould to microwave irradiation and the temperature of the steam is directly controlled by the pressure inside the mould.
