Vapor Degreasing Re-Gaining Wider Heat Treat Acceptance

  Source:  Today’s Medical Developments

Vapor degreasing has historically played a critical part in the heat treating process. When oils get on the parts, the parts often have to be cleaned. In the past, vapor degreasing was a very popular way of cleaning the parts, but it became an environmental issue because the solvents used were problematic. Other cleaning solutions were adopted but typically were not as effective as vapor degreasing.  Now vapor degreasing is making a comeback with less problematic solvents.  This article, although not dealing specifically with heat treating, will have a significant impact on heat treaters.

Heat Treating of Jaw Fixation Plates Provides Superelasticity

  Source:  Bioengineering

Process parameters and post-processing heat treatment techniques have been developed to produce both shape memory and superelastic NiTi using additive manufacturing. By introducing engineered porosity, the stiffness of NiTi can be tuned to the level closely matching cortical bone. Using additively manufactured porous superelastic NiTi, we have proposed the use of patient-specific, stiffness-matched fixation hardware, for mandible skeletal reconstructive surgery.

Medical Manufacturer Chooses Vacuum Furnace System

A vacuum heat-treating system with 2-bar gas quenching was shipped to Costa Rica and will be used to manufacture surgical components. The TITAN® H2, manufactured by Ipsen, helps companies accelerate the pace of innovation while satisfying the strict legal requirements of the medical industry.

The standardized vacuum furnace features an 18″ x 24″ x 18″ (455 mm x 610 mm x 455 mm) all-metal hot zone with a 1,000-pound (450 kg) load capacity. It is capable of operating at temperatures of 1,000 °F to 2,400 °F (538 °C to 1,316 °C) with ±10 °F (±6 °C) temperature uniformity. Equipped with the PdMetrics® platform for predictive maintenance – which securely connects to a network of integrated sensors on the furnace to gather and analyze data, run algorithms and provide real-time diagnostics – the furnace provides sophisticated monitoring of critical systems and key parameters that improve the health and integrity of the equipment. The company also received a gas backfill reservoir, a loader with a 2,000-pound (907 kg) load capacity and a complete air-cooled, closed-loop water system.
