Aplix Automotive Group in Southfield, Mich., has developed a technology called inter-mold for molding in hooks on car headliners, instead of using the labor-intensive insert molding process.
Inter-mold does not require fasteners to be inserted into the mold before injection. The hooks are formed simultaneously during molding.
Aplix said the field of hooks can be any shape or size, in virtually any location on the part. The method works with many polymers, including polypropylene, polyethylene, nylon, acetal and thermoplastic elastomers.
Inter-mold is being used for headliner attachment brackets on the 2007 Ford Edge and Lincoln MKX.
