The RPS 3 Phase Process

1. Loading a measured quantity of polymer into the mold.
   
   

2. Heating the mold in an oven whilst it rotates, until all the polymer has melted and adhered to the mold wall. The length of time the mold spends in the oven is critical. If the mold is in too long the polymer will degrade, reducing the strength. If the mold spends too little time in the oven, the polymer melt may be incomplete. The polymer grains will not have time to fully melt resulting in large bubbles in the polymer. This has an adverse effect on the mechanical properties of the finished product.
   
   

3. Cooling the mold, usually by fan. This stage of the cycle can be more lengthy depending on the component. The polymer must be cooled so that it solidifies and can be handled safely by the operator. The component will often shrink on cooling, coming away from the mold, and facilitating easy removal of the part. An uncontrolled cooling rate can producing a warped part.
