Pulp Mold Machine
Dynapore® Mold Screen
Dynapore Improves Screen Longevity
In pulp molding machines, a slurry of paper pulp fibers is drawn onto a wire mesh
screen, flash dried into a solid, and then ejected off the screen while maintaining the original shape of
the screen. Common molded pulp products include egg trays, apple trays, fast food packaging, protective
shipping forms, and many other uses. A single layer stainless steel wire mesh screen is generally formed
into the shape of the desired part. The repeated cycle of slurry under vacuum, dry and eject results in
fatigue failure of the screen over time. Since the screen is not sintered, some apertures in the screen
are extremely deformed during the forming operation resulting in uneven pulp distribution or screen rejection.

Dynapore® Is the Best
Solution for Savings
A DynaporeŽ multi-layer laminate is sintered and fully annealed and can be
formed into shallow or moderately deep forms without cracking or extreme aperture
deformation . The multi-layer structure offers much greater strength than a
single layer mesh and thus has a fatigue life much greater than single-layer
un-sintered wire mesh. This results in tremendous cost savings over time,
since downtime to change molds is significantly reduced.
