Abstract: Disclosed is a high pressure injection molding system employing one or more plastic injection molding workstations including split molds, a single plastic extruder coupled to a heated manifold capable of delivering fluid plastic to multiple workstations, and wherein final lockup of the split mold halves results in application of compressive forces effective to maintain the split mold halves in nominal position during high pressure injection molding conditions. Operational movement is performed by use of a single remote pumping station utilizing pressure compensated pumps, accumulators and manifolds. The independent mold workstations allow independent operation while providing efficency of operation for the hydraulic system and extruder system.

Abstract: A molded plastic product and material handling pallet comprising upper and lower pieces of different plastic materials assembled in separable mating registration to provide a pervious product bed and a lower framework of sufficient strength for vertical stacking storage of product-loaded pallets in open racks.

Abstract: An interlocking modular pallet apparatus and method of construction and de-construction which includes plastic modular components aligned in a two-by-two arrangement with interlocking male and female tabs which connect in a vertically sliding manner to form an upper support structure with a series of upper apertures through the platform surface. A set of rail components are interconnected in a perpendicular manner to form an evenly spaced grid with corresponding lower apertures. Hollow formed spacing members are placed between each aligned aperture pair. A first interlocking insert is placed through each upper aperture and a second interlocking insert is placed through each lower aperture. The first and second inserts interlock to join the upper support structure with the lower rail assembly, with the spacing members forming cavities for insertion of lifting device appendages. The completed pallet device also includes frictional pads attached across its surface to prevent loads from sliding off.

Abstract: An interlocking modular pallet apparatus and method of construction which includes plastic modular platform sections aligned in a two-by-two arrangement with interlocking flanges between the adjoining surfaces of the platform sections. A plurality of leg structures extend down from the lower surface of the platform sections. A center conical support structure with a locking lip or tab is formed by the adjoinment of the platform sections. A band or ring of durable material, e.g. metal, is placed onto the conical structure to draw and lock together, via the locking tab and ring, the adjoining platform sections. A series of upper and lower frictional, rubberized pads are aligned and interlocked through the lattice holes along the perimeter of the pallet lattice.

Abstract: An interlocking modular pallet apparatus and method of construction which includes plastic modular platform sections aligned in a two-by-two arrangement with interlocking flanges between the adjoining surfaces of the platform sections, the flanges interlocking in a downward sliding manner. A plurality of leg structures extend down from the lower surface of the platform sections. A center conical support structure with a locking lip or tab is formed by the adjoinment of the platform sections. A band or ring of durable material, e.g. metal, is placed onto the conical structure to draw and lock together, via the locking tab and ring, the adjoining platform sections.

Abstract: A modular pallet system definable in terms of xyz Cartesian coordinates includes a base structure in a lower xy plane having a x- and y-linear axis members internestable with each other at regions of orthogonal intersection to form a rectilinear matrix, each region of intersection of each linear member including an aperture of like geometry to each other aperture. The pallet system further includes a lower snap-lock elements, equal in number to that of the regions of orthogonal intersection, the snap elements proportioned for complemental securement within each of the apertures within each of the regions of orthogonal intersection of the x- and y-axis members with each other, each of the lower snap-lock elements including integrally projecting positive z-axis locking prongs.
