Method of making a laminated trim component

A method of making a laminated trim component is provided. A heated plastic composite sheet is pressed against a heated laminated sheet to bond a plastic cushioning layer of the laminated sheet to the plastic composite sheet. The step of pressing compresses a portion of the laminated sheet spaced inwardly from an outer periphery of the laminated sheet to locally compact and thin the cushioning layer at the portion to form a compressed portion of the cushioning layer. Interior portions of the sheets stretch during the step of pressing while remaining intact.

CONTAINER MANUFACTURING METHOD

A container manufacturing method includes: a liquid discharge step in which a predetermined amount of liquid (L) in the container (C) is discharged to the outside by supplying pressurized air from air holes (13) provided in a blow molding mold (11) to a cavity (12) and pushing an outer surface of the container (C) after molding by the air; and a headspace forming step in which a headspace (HS) is formed in the container (C) by separating a filling nozzle (22) from a mouth portion (Ca) of the container (C) in a state in which a predetermined amount of liquid (L) is discharged to the outside.

Method of Making a Vehicle Interior Component Having an Integral Airbag Component

A method of making a vehicle interior component having an integral airbag component is provided. The method includes disposing a polymeric composite sheet having inner and outer surfaces onto a first surface of a mold at a molding station and compressing the sheet between the first surface and a second surface of the mold at the molding station.

Method of Making a Vehicle Interior Component Having an Integral Airbag Component and a Fibrous Decorative Covering

A method of making a vehicle interior component having an integral airbag component and a fibrous decorative covering is provided. The method includes providing a polymeric composite sheet and a fibrous decorative covering overlying an outer surface of the composite sheet. The composite sheet is pressed against the covering after the steps of providing to bond the covering to the composite sheet. A molten polymer compatible with the polymeric material of the composite sheet is injected into a mold cavity in accordance with a predetermined set of process parameters which are high enough to integrally form at least one airbag component via polymeric interfusion at the inner surface of the composite sheet but low enough to avoid damaging the covering.

Method of Making a Trim Component Having an Edge-Wrapped, Fibrous Decorative Covering

A method of making a trim component having an edge-wrapped, fibrous decorative covering is provided. A fibrous decorative covering overlies and is in contact with an outer surface of a composite sheet. The composite sheet is pressed against an interior portion of the covering to bond the interior portion to the composite sheet while maintaining at least one exterior edge portion of the covering unbonded to the composite sheet. A molten polymer compatible with the polymeric material of the composite sheet is injected in accordance with a predetermined set of process parameters which are high enough to integrally form at least one structural component via polymeric interfusion at the inner surface of the composite sheet but low enough to avoid damaging the covering. The at least one unbonded, exterior edge portion is folded over the composite sheet to form the trim component.
