Abstract
The present invention relates to a novel device to manufacture polyurethane foam boards used in structurally insulated panel known as insulated building material press. The press enables the application of pressure across a large area while foaming and curing polyurethane under pressure, curing glue or otherwise bonding materials into a finished product. The press uses a simple principle to distribute pressure evenly across the platens avoiding the need for heavy and expensive parts used in the construction of building material presses of the prior art.
Claims12
A building material press to make structural insulated panels comprising,
- a) opposing press platens to form said structural insulated panel,
- b) one or more tensioning devices around the press to link all the press components together while providing the necessary tension, and,
- c) one or more sets of tension transfer structures attached to the outside face of each platen to give internal structural support, provide rigidity and to transfer pressure from said tensioning device to said platens,
- wherein each tension transfer structure has the shape of a cylinder, pyramid, prism, dome or cone.
