AN INVESTIGATION ON P/M POROUS MATERIALS USED FOR FOUNDRY TOOLS AND DEVICES

A rudimental experiment was tried on the illustration of P/M bronze filtering components used for cold box tools by investigating the technologies of triethylamine air spray cold boxes. It has been founed that production costs can be decreased and casting qualities can be improved by using P/M bronze filtering components as venting units. This is a trial to extend the application range for these porous materials.
