Abstract: Method and apparatus for controlling the stacking height of stackable products during compression molding off stops includes slides that are movable into and out of an end of blind pockets in a compression mold in which the stack height surfaces are formed during the molding cycle. The slides are held in a retracted position until after the mold is closed and the molding compound flows to the shape of the molding cavity inside the mold including the blind pockets. Then the slides are extended into the ends of the respective blind pockets the same distance to compress the molding compound and obtain the desired height of the stack height surfaces formed by the blind pockets.

Abstract: A preformed pallet is provided having first and second outer layers that sandwich a cellular or honeycomb shaped core. The peripheral edge of the preformed pallet may be inserted into the molding device having one or more heating elements, which function to focus heat onto the peripheral edge. Once heated, the peripheral edge of the preformed pallet may be reshaped by one or more die sets forming the peripheral edge into an enclosed pallet.

Abstract: A preformed laminate is provided having first and second outer layers that sandwich a cellular or honeycomb shaped core. The peripheral edge of the preformed laminate may be inserted into the heating apparatus having one or more heating elements surrounded by a reflective back panel and one or more heat shields, which function to focus heat onto the peripheral edge. Once heated, the peripheral edge of the preformed laminate may then be inserted into a molding press having one or more adjustable pinch rails for forming the peripheral edge of the laminate into an enclosed pallet.

Abstract: A tray suitable for use in mass raising insect larva, particularly flys (flies), in and artificial environment from incubation through hatching and growth and including a smooth bottom and four upwardly extending sides being open about fifty percent (50%) of the total height to provide sufficient ventilation to maintain a predetermined temperature to satisfy the developing process. The trays are stackable and have ribs at their corners to provide structural strength.

Abstract: A tray is disclosed especially suitable for use in the candy industry. The tray has a unique arrangement of legs, lugs, and anti-slip features which facilitate stacking, handling, and cleaning of the trays.
