INJECTION FOAM MOLDING METHOD

In an injection foam molding method, a relationship between a flow front moving speed (cm/s) of a foamed resin material in an injection step of injecting the foamed resin material into a cavity and amount of gas generated per 1 g of a resin material (ml/g) is defined as follows: the amount of gas generated per 1 g of the resin material is 0.36 ml/g or more; and the flow front moving speed (cm/s) is 75the amount of gas generated per 1 g of the resin material (ml/g)35 or more and 12 cm/s or more.

Biodegradable, Industrially Compostable, and Recyclable Injection Molded Microcellular Flexible Foams
20210039346 · 2021-02-11 · ·

This document discloses a process for manufacturing recyclable injection molded microcellular foams for use in, footwear components, seating components, protective gear components, and watersport accessories. The process includes the steps of providing a thermoplastic polymer which comprises at least one monomer derived from depolymerized post-consumer plastic, inserting a fluid into a barrel of a molding apparatus. The fluid is introduced under temperature and pressure conditions to produce a super critical fluid. The process further includes mixing the thermoplastic polymer and super critical fluid so as to create a single phase solution, and injecting the single phase solution into a mold of an injection molding machine under gas counter pressure. The process further includes foaming the single phase solution by controlling the head and temperature conditions within the mold.

Structural Foam Molding Method Using Continuous Fiber Composites, and Parts Formed Therefrom
20210031415 · 2021-02-04 ·

A method for making structural foam parts having continuous aligned fibers includes placing an assemblage of fiber-bundle-based preforms in an injection mold, creating a melt flow of resin and, optionally, short, loose fiber, and adding foaming agent to the melt flow. When the foaming agent/melt flow mixture is introduced into the injection mold, the foaming agent foams. The assemblage is structured and positioned so that fibers therefrom adopt a desired alignment and position in the final part. Structural foam fills the remainder of the volume of the part.

INSULATION INJECTION DEVICE

A thermal insulation injection gun includes a pointed nozzle that prevents blocking of the nozzle by a distal panel of a building cavity and/or by pre-existing insulation within the cavity. In embodiments, the pointed nozzle can be pressed through a panel, thereby forming the injection hole. An enhancement port can be provided through which an enhancing material such as a carrier fluid, particulate or fibrous insulating material, a binder, or a fire retardant can be added and mixed with the insulating material. Embodiments include expanding nozzle wings that can compress pre-existing insulation to create a space on a proximal or distal side thereof for injecting the insulation. A compressible sheath installed over the nozzle can prevent dripping of excess insulation from the panel hole. Exchangeable collars can be used to fix an insertion depth of the nozzle and/or to block selected lateral dispensing ports of the nozzle.
