The flow conditioning structure can include a ridge extending from the hot surface.

Abstract: A method of forming a thermoplastic polymer film includes melting and subjecting a polymer resin material to shear stresses in a range of 250 kPa to 400 kPa to form a refined resin material and forming the thermoplastic polymer film from the refined resin material. The film is substantially free of microgels having a largest dimension greater than 50 microns. The film has a thickness in a range of 15 micron to 80 microns. The film has a microgel count in a range of 0 to 0.2 per mm2 of microgels having the maximum dimension greater than 10 microns.

Abstract: A tappet, which may be a fuel pump actuator, includes a body that is a contiguous piece of case-hardened ferrous metal. The body has a cylinder-conforming bore-running surface and an anti-rotation guide feature that has been made by stamping to project outwardly from the bore-running surface. A cam follower is mounted to the body. The body has been case hardened by ferritic nitrocarburizing, but has not been distorted by heat treatment and has a malleable interior. A transverse web for the tappet may be fully hardened. Axle holes for the cam follower may be formed by stamping. The tappet is durable and provides superior alignment of the roller to a cam, which reduces friction and noise.

Abstract: The present disclosure generally relates to methods and apparatuses for forming cast parts having cast in features aligned with a casting core. The part is cast around a casting core within a casting shell. The casting core has a first feature that creates a corresponding second feature of the cast part.
