Injection molding method

An injection molding method comprising: a mold clamping step of clamping a first mold and a second mold to form a mold cavity; a first injection filling step of injecting a foamable molten resin into the mold cavity to fill an interior of the mold cavity with the foamable molten resin, after completion of the mold clamping step; a mold cavity expansion step of expanding the mold cavity by a specified quantity to cause the foamable molten resin to foam, after the start of the first injection filling step; and a second injection filling step of pouring a molten resin or gas into the foamable molten resin within the mold cavity, after the completion of the first injection filling step, and after the start of the mold cavity expansion step.

Foam cord for seating foam stability and rigidity

A vehicle seating assembly includes a seatback having a frame that provides structural integrity to the seatback and operably couples the seatback to a vehicle floor. A carrier is operably coupled to the frame. A foam cushion assembly is operably coupled to the carrier. The foam cushion assembly includes an upper portion, a lower portion, a first side bolster, and a second side bolster. A continuous semi-rigid foam cord is formed in the foam cushion assembly. The foam cord extends through a forward periphery of the upper portion, the lower portion, the first side bolster, and the second side bolster. The foam cord is configured to add structural rigidity to the seatback.

APPARATUS AND METHOD FOR MANUFACTURING CRASH PAD

An apparatus for manufacturing a crash pad having a foam layer by injecting and foam-molding a foam liquid between a base and a skin may include a first mold and a second mold which mold the base by injecting molten resin into a base forming space formed in a mold-closed state and a vacuum mold for vacuum-molding the skin, in which when the vacuum mold to which the formed skin may be attached may be mold-closed with the first mold, a foam space may be formed between the skin and the base of the first mold, and an injection channel for injecting the molten resin into the base forming space and a foam liquid injection channel for injecting the foam liquid into the foam space may be provided in the first mold, such that the first mold may be used as a foam mold, together with the vacuum mold.

Method of producing container product
12257746 · 2025-03-25 ·

A method of producing a container product comprises providing a mold including a first part and a second part. The mold is closed to define a cavity having a first area and a second area. A molten plastic composition including a polymer and a physical blowing agent is filled into the cavity. Then, the molten plastic composition in the cavity is cooled, such that the molten plastic composition in the first area is completely cooled and solidifies or a central portion of the first area has micro uncooled molten plastic composition. The second area has the plastic composition in the molten state. The first part of the mold is moved in the axial direction. The molten plastic composition in the second area forms a beehive foam after foaming and expansion. Then, the foamed container product in the mold is cooled to take shape and then removed after opening the mold.

Mold for processing expandable or expanded plastic particles

Mold for processing expandable or expanded plastic particles for producing a multi-component particle foam component, that includes a mold cavity delimited by mold walls, having at least one mold element, which in particular is slide-like or slide-shaped, wherein the at least one mold element is mounted so as to be movable between a first orientation and/or position and at least one further orientation and/or position in which it projects at least in portions into the mold cavity, and wherein the at least one mold element is designed with, or has, a flow channel structure having at least one flow channel which extends inside the mold element and through which a process fluid can flow.
