Description

Diamond D Cake is a hard blocking material used for blocking together a series of lenses or work pieces that are to be edged or profiled.  Other applications include thin film blocking, Blanchard wheel work, spot blocking, surface protection and a variety of uses where semi-hard, high tack materials are desired. 

Application

Depending on application, Diamond D Cake can be applied in two basic methods:
Pre-melt Diamond D Cake h in a controlled heating vessel, and apply or pour molten pitch to blocking plate or lap, and then mount the workpiece.
Pre-heat the blocking plate or lap and work piece, and wipe the pitch across the heated tool and mount the workpiece.
Diamond D Cake can be removed from the parts by using Uniclear. For best results, please consult with UPI technical staff to recommend optimal processing conditions.
