The present invention relates to a method for manufacturing thermoplastic polymer particles, and the thermoplastic polymer particles, the method comprising the steps of: (1) extruding a thermoplastic polymer resin through an extruder; (2) spraying the extruded thermoplastic polymer resin through a nozzle and then spraying a gas to the sprayed thermoplastic polymer resin through a plurality of sprayers so as to granulate same; and (3) cooling the granulated thermoplastic polymer resin.

The invention relates to a mixing chamber in which a first liquid comes into contact with a second liquid, and a gas injection device designed to inject a gas into the mixing chamber, wherein the gas injection device comprises: a gas source to provide the gas at a predetermined pressure, and a metering unit to limit the gas provided by the gas source to a predetermined flow rate, wherein the metering unit is in contact with the mixing chamber on a gas outlet side of the metering unit, wherein the gas outlet side of the metering unit comprises an elongated gap, wherein the gas passes out of the metering unit into the mixing chamber via the elongated gap, and wherein the gas passes out of the metering unit into the mixing chamber.

A nozzle and a process suitable for dispensing liquid foamable products, particularly useful with carbon dioxide blowing agents, the nozzle comprising a tubular exit zone having an inlet and an outlet; the tubular exit zone having an inner wall surface defining a passageway for dispensing having a centerline axis; the tubular exit zone further having a plurality of vanes attached to the inner wall surface parallel to the centerline axis with the vanes extending radially into the passageway for dispensing; the vanes having a length dimension that is the distance the vane contacts the inner wall surface parallel to the centerline axis, a thickness dimension that is the effective thickness of the vane at the inner wall surface perpendicular to the centerline axis, and a width dimension being the distance from the inner wall surface that the vane extends into the passageway for dispensing; and wherein the vanes do not connect or touch at the centerline of the passageway for dispensing.

A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

A foam dispensing apparatus and system thereof can be used for dispensing a mixture of a resin component and an isocyanate component. The foam dispensing apparatus contains a heated hose assembly, a spray gun containing a spray head and a mix tube, and a nozzle for dispensing the resin and isocyanate components from the spray gun. Components of the foam dispensing system are lightweight and/or low cost thereby facilitating use and maintenance.

A foam dispenser having a metal housing has a spool valve socket therein. A metal handle extends from the housing. A spool valve is disposable within the spool valve socket. A trigger couplable to the spool valve enables the spool valve to be rotated between open and closed orientations within the housing. The spool valve has internal channels for selectively passing liquids through the spool valve in the open orientation and not in the closed orientation. The spool valve also has a channel for selectively passing a gas through the spool valve in both the open and closed orientations.

A device (1) and method for the production of plastic parts (2), having a first plastic feed device (3a) for feeding a first liquid plastic starting component (K1); a second plastic feed device (3b) for feeding a second liquid plastic starting component (K2); a mixing device (5) with a mixing chamber (6), wherein in the mixing chamber the liquid plastic starting components that can be fed by the plastic feed devices can be mixed to form a plastic mixture (KG); a discharge nozzle (7) for discharging the plastic mixture; and a cooling device (8) for the mixing device, wherein a drying device (9) surrounding the mixing device at least in regions is provided, wherein the drying device has a separating device (10), a drying chamber (T) formed between the separating device and the mixing device, and a desiccant feeding device (11) opening into the drying chamber are disclosed.

The application relates to a method and apparatus for producing a solid foam continuously. A homogeneous suspension is formed from a raw material in which the suspension comprises a solidifying agent, and a foam mixture which comprises bubbles is formed by mixing air bubbles into the suspension. The foam mixture is injected via at least one nozzle to form a foam pattern and the foam pattern is laid on a moving surface and the foam mixture of the foam pattern is solidified in order to form a solid foam such that the bubbles of the foam mixture shrink in off-length directions to form the shaped bubbles. Further, the application relates to the product and the use of the method.
