Presently, we are designing and developing a safer military marine hull which is lighter than water and unsinkable. Which will be able to carry a larger payload while traveling a greater distance with less fuel then present marine hulls. Also will have more resistance to small arms fire, reduced draft with greater performance in blowing whitecaps. This will save lives on manned boats. Molding process is rotational with a double wall molding the inner wall to the outer wall during the molding process. Modular hulls will reach widths to 40' with lengths well over 150'. Patent issued 2002 with prior art going back to 1969/1970. Additional patents to follow.
Recent mold completed for compression molding of rubber shock mounts for a fuel tank.
It's completed in a two cavity tool.
Here are the two cavities molding our product
Here it is our product (Shock Mounts) after molding You will notice the little fingers standing up these are air bleed lines, they will be trimmed off before assembly
These are patterns for the Aluminum Casting, which will be used for the Rotomolding Process.

Four cavity Injection tool with one cavity cut for injection slide rail system.
Vacuum formed air box for controlling air intake and wave water.
This is the extrusion rail system for controlled bending. Foam blocks slide in (2). Custom Injection molded parts fit into machined slots.
View through the jet drive pattern opening shows the inter wall, configuration using a double wall rotational molded marine hull, which in turn is molded to the outer wall chine's covered, by issued Widmer patent.
