Abstract: A method of forming a hot stamped, die quenched, and die trimmed part is provided. The method includes hot stamping and die quenching a blank with a quench die and forming a die quenched panel. The quench die includes at least one slow-cooling channel. The die quenched panel is die trimmed along the at least one localized soft zone that is adjacent a hard zone. The blank may be formed from a press hardenable steel (PHS), and the at least one soft zone may have a ferritic microstructure and the at least one hard zone may have a martensitic microstructure. The at least one localized soft zone may have a microhardness between about 200 HV and about 250 HV and the hard zone may have a microhardness between about 400 HV and about 500 HV.

Abstract: A tow hook includes a monolithic additively manufactured side wall defining a vehicle attachment member, a hollow main body extending from the vehicle attachment member, and a hollow towing member extending from the hollow main body. The vehicle attachment member is configured to rigidly attached to a vehicle and the hollow towing member is configured to securely attach to a towing machine such that the vehicle is towable via the tow hook. The vehicle attachment member can be a threaded shaft with a bore extending along a length of the threaded shaft. The side includes a chamfered plurality of apertures extending from an inner surface of the side wall to an outer surface of the side wall, and having with an inner dimension along a length direction of the hollow main body greater than an inner dimension along a circumferential direction of the hollow main body.
