Filled grades mould design

With assistance of ICI various alternative grades of filled PP were considered but the final selection was made by actually moulding a tank and subjecting it to in-service tests. The tank was of such a complex shape that a theoretical approach to material selection was out of the question. The preferred method was to construct a mould suitable for SF mouldings and try out different materials. This approach may, of course, necessitate modifications to be made to the mould (as was the case with this tank mould). It was pointed out by Philips designers that because of the novel nature and complexity of the product the development of the... 

When designing mouldings in reinforced and filled PP, the general guidelines for design of the product and the mould are the same as those for unreinforced PP. However, filled and reinforced grades require some extra consideration ...
