APPLICATION: David Wolfe Design Roto-Poppet ("RP") Inserts are used when there
is a need to assist in the removal of the already roto-molded part
from the mold by introducing positive air pressure between the
molded part and mold cavity during de-mold. DWD "RP" Inserts are
made from M-1 aluminum and to be used in conjunction with DWD "SL"
Series Air Poppets sold separately.
INSTALLATION: DWD "RP" Inserts have been designed to be installed in an area of
the mold with a nominal thickness of 3/8". This may be achieved by
either spotfacing or building up the backside of the mold as
necessary. A nominal 1" hole then needs to be bored through the
mold shell. The "RP" Insert should then be installed from the back
side of the mold and welded in place. Install the DWD "SL" Series
Air Poppet from the face of the mold securing with the supplied
SHCS. Plumb the air supply to the 1/8" NPT port on the back of the
insert.
