Abstract: A foamed material for shoes includes a foamed body made by foaming a mixture of a molten thermoplastic elastomeric material and a supercritical fluid. The foamed body has a density lower than 0.35 g/cm3, and includes multiple foamed pores, each of which extends in a longitudinal direction to terminate at two opposite lengthwise ends and in a width direction perpendicular to the longitudinal direction to terminate at two opposite widthwise ends. Each foamed pore has a maximum length defined by a distance between the lengthwise ends and a maximum width defined by a distance between the widthwise ends, and a ratio between the maximum length and the maximum width is at least 2:1. A method for manufacturing the foamed material is also disclosed.

Abstract: A foam molding device includes an outer mold unit and an inner mold unit. The outer mold unit includes an outer upper mold and an outer lower mold that cooperatively define a receiving space. The inner mold unit is detachably disposed within the receiving space, and includes an inner upper mold and an inner lower mold. The inner upper mold and the inner lower mold cooperatively define a foaming space adapted for foam molding a foam material into a foamed object.

Abstract: A molding device includes first and second molds, and a material passage. The first mold includes a first porous layer including a first porous main body, a first molding surface and a first connecting tube formed in the first porous main body. The first mold has a first gas passage for a gas to be supplied into the first porous main body. The second mold includes a second porous layer including a second porous main body, a second molding surface cooperating with the first molding surface to define a cavity, and a second connecting tube formed in the second porous main body. The material passage extends through one of the first and second molds, and is spatially communicated with the cavity for entrance of a supercritical foaming material into the cavity.

Abstract: A shoe sole molding device adapted for heating and molding a foamed material into a shoe sole includes a mold seat unit, a core unit, an induction heating unit and a coil unit. The core unit is disposed in a core receiving space of the mold seat unit, and defines a cavity for receiving the foamed material. The induction heating unit is disposed around the core unit, and has magnetic permeability greater than that of the core unit. The coil unit is disposed around the induction heating unit, and provides electromagnetic wave to induce heating in the induction heating unit to heat up the core unit and the foamed material.

Abstract: A mold device includes a lower mold seat, a lower die core assembly mounted to the lower mold seat and including a lower die core unit defining a mold cavity, an upper mold seat, and an upper die core assembly mounted to the upper mold seat and including an upper die core unit covering the mold cavity. The lower die core unit includes an internal loop for a cooled gas to flow therethrough, and is made of a first porous material so as to allow the cooled gas to flow out of the lower die core unit. The upper die core unit includes an upper die core passage for the cooled gas to flow therethrough, and is made of a second porous material so as to allow the cooled gas to flow out of the upper die core unit.

Abstract: A molding device includes a lower die core assembly including a porous lower die core unit, an upper die core assembly including a porous upper die core, a heating assembly for heating the lower die core unit and the upper die core, and a control assembly operable to control temperature of an assembly of the lower die core unit and the upper die core to be direct proportional to a distance by which the upper die core is moved downwardly from a compression starting position where the upper die core comes into contact with the lower die core unit. The control assembly is further operable to control one of a heated gas and a cooled gas to be introduced into and discharged from the upper and lower mold core assemblies at different rates.

Abstract: A molding device includes lower and upper die core assemblies. The lower die core assembly includes at least two lower die core units surrounding a central axis and defining a mold cavity. The lower die core assembly is convertible between an open state and a closed state. When converted from the closed state into the open state, the lower die core units are moved away from the central axis. When converted from the open state into the closed state, the lower die core units are moved toward the central axis to compress the foaming material. The upper die core assembly is convertible between a lifted state, where the upper die core assembly is spaced apart from the lower die core assembly, and a lowered state to cover the mold cavity.
