The first and foremost disadvantage is that to ensure the structural integrity of the metal disk against the injection molding pressure, the area of the solid metal will be greater than the aggregate area of the small-diameter holes contained within the metal disk.
The high melt flow rate of 80R90CD clarified PP reduces maximum molding pressure, allowing lower-tonnage machines to be used and contributing to longer tool life and reduced maintenance.
An IR lamp was the only thermal source, whereas the molding pressure was provided by means of a small pneumatic cylinder.
