Instructions for use of Bull Plate Lube
Bring mould up to casting temperature and fill cavities with alloy.
Be sure to have complete base fill out to avoid getting Bull Plate Lube in the cavities.
Cut the sprue and keep blocks together with boolits in cavities.
Lightly dampen a Q-tip with Bull Plate Lube and spread a light film of lube on the mould block top surface and bottom of sprue plate.
With a clean Q-tip wipe away any excess lube from both surfaces. Only a very small amount is needed.
Also apply to alignment pins and hinge points.
New or very clean mould may require more than one treatment. Reapply at the first sign of any drag on opening or closing sprue plate.
Repeat procedure at the beginning of each casting session.
