Process

This is a fairly simple process utilising

Fairly high processing temperatures in excess of 280°C, sheet metal or aluminium moulds, biaxial rotation on 2 different axes, fine powders or liquid polymers and then cooling. This produces hollow, seamless and low induced stressed parts.

 

LOADING THE RESIN

FUSING THE RESIN

COOLING THE RESIN

UNLOADING

A closable mould which is mounted onto the arm of the machine is charged with the polymer resin. The mould is closed using bolts or other mechanical clamping mechanisms.

The closed mould is rotated continually on the 2 different axes at low speed inside a closed oven. The oven is heated using an energy source of choice. The resin melts and adheres to the mould’s inner surface until the inner surface is completely coated.

The mould’s arm then moves the mould out of the oven whilst continually rotating on the 2 different axes and into a cooling station.

Once the resin is sufficiently solidified, the mould is split open and the moulded part is removed.
