A method and apparatus for dispensing a foam product, wherein an elastomeric base material, which is solid at ambient temperatures, and a liquid material are combined to form a foam product, comprising heating the base material to melt the material, heating the liquid material to maintain the liquid at an elevated temperature above ambient, metering simultaneously portions of the base material and liquid material, mixing the portions, thereafter heat conditioning the mixture at a temperature above the melting temperature of the base material, subsequently conditioning the mixture to a lower temperature below that of the melting temperature of the base material and finally elevating the temperature of the mixture to about the melting temperature of the base material to provide a product suitable for use as a sealant such as a gasket. The temperatures and pressures of the materials throughout the dispensing are controlled thereby producing a uniformly consistent and repetitively formed foam product.

Method and apparatus for dispensing a foam product

A mixing and dispensing gun comprising a body having spaced inlets for receiving two components of an adhesive or reactive fluid, a dispensing valve in the gun, an outlet nozzle and a motionless mixer interposed between the dispensing valve and the outlet nozzle for directing the fluids in a sinuous path and mixing the fluids.
