In the method for manufacturing conglomerate stone slabs using the Bretonstone technology, in the variant where the starting mixture is enclosed between two paper sheets, the improvement consists in replacing each paper sheet with a containment element consisting of a paper sheet, one surface of which has, applied thereon, a film of plastic material which is impermeable to organic vapours, impermeable to the liquids and in particular to the liquid resin constituting the binder of said mixture, resistant to the catalysis temperatures of the said resin and resistant to hot solvents and chemical vapours. Preferably, said plastic material is water-soluble, in particular polyvinyl alcohol.

Provided is a method for manufacturing a fiber reinforced plastic molded body, the method including: performing thermocompression molding, by using a molding die, on a molding precursor which is obtained by arranging a prepreg including a thermosetting resin and a fiber around a thermoplastic solid body.

The present invention relates to a plastic based high density wood fiber composite (HDWFC) product and a method for manufacturing said composite product. The invention also relates to an apparatus for manufacturing said composite product.

Method and tools for manufacturing core foam sections for a propeller is disclosed. In an embodiment, a method comprises wrapping a first adhesive film around pre-drilled rods; placing the rods into a first mold using placement features; injecting a high density material into the first mold and around the rods; curing the high density material to form a first cured component; removing the first cured component from the first mold; placing a second film adhesive onto the first cured component; placing the first cured component into a second mold; closing the second mold; injecting a low density material into the second mold; curing the second density material to form a second cured component, wherein the first and second cured components are bonded together.

An apparatus including one or more panels including an outer face sheet comprising a plurality of first composite materials; an inner face sheet comprising a plurality of second composite materials; and a plurality of foam pieces disposed between the outer face sheet and the inner face sheet, wherein the foam pieces reduce warping of the panels.

A perforated expanded low density polyethylene foam layer, wherein in the expanded low density polyethylene layer at least 80% of the blowing agents are dissipated from closed cells within the expanded low density polyethylene layer forming evacuated closed cells whereby a partial vacuum is formed within the closed cells of the low density polyethylene layer.

The present invention relates to methods of manufacturing moulded products, for example building panels, and in particular, but not exclusively, to manufacturing a panel comprising natural stone or rock set into a polymeric layer. The method of manufacturing a moulded product as described herein comprises at least one article being set into a polymeric layer, followed by placing the at least one article and particulate ferrous material in a container so that at least a portion of the or each article is embedded in the particulate ferrous material, introducing a polymeric material into the container to form the moulded product, and removing the moulded product from the container.
