Plastic Thermal Treatments

 

Find Suppliers by Category

Heat treating services perform thermal treatments to modify the properties of metals and metal alloys. Common processes include annealing, austempering, case hardening, conventional hardening, homogenizing, hot isostatic pressing (HIP), martempering, normalizing, precipitation hardening, shot peening, solution treating, spheroidizing, stabilizing, and stress relieving.

  • Design of Plastic Gears (.pdf)
    characteristics are also being enhanced with 3. Plastic gears are subject to greater dimensional instabilities,. new developments, both in materials and processing. In this regard, plastics. due to their larger coefficient of thermal expansion and moisture. contrast somewhat dramatically
  • Proper Use Of Plastic Gears (.pdf)
    Due to the thermal expansion of plastic gears, which is significantly greater than that of metal gears, and the effects of tolerances, one should make sure that meshing gears do not bind in the course of service. Several means are available for introducing backlash into the system. Perhaps
  • Laser Staking Securely Joins Plastic Parts for Printed-Circuit Boards
    Laser staking automates printed-circuit-board packaging without damaging delicate electronics. LPKF Laser & Electronics AG * Laser staking positively locks two dissimilar plastics together. * Staking can mount printed-circuit boards in plastic housing. * It also permits process tracking
  • Failure Mode Analysis of Medical Resection Loops Using Thermal Imaging
    for treatment of BPH or removal of small tumors, like those found in the bladder. A dynamic study was performed showing the heating, cooling and temperature profile (hot spots) in these loops while they were energized. A 14 bit thermal video was obtained that captured potential failure areas in the product
  • Thermal spray: Better performance for less
    Engineered coatings and advanced processing methods help push performance limits for metal and plastic components. Here are design guidelines and processing tips that will help extend the life or improve the aesthetics of that new design. Edited by Jean M. Hoffman A plating process called Udique
  • Stem Cell Use in the Surgical Treatment of Tennis Elbow (.pdf)
    This paper discusses how thermal imagery can provide new understanding of diagnosis, cause and treatment of medical conditions. In this instance, the thermal image of a tennis elbow seen at a recent Inframation Conference visualized a hot spot at the location of the small tear in the tennis elbow
  • Fatigue Life Improvement of Welded Elements by Ultrasonic Peening
    dramatic results, including reduction of forging force to zero, virtual. elimination of "barrelling" and reversal of the residual stress distribution. It was suggested. that these benefits were a result of reduced friction, elasto-plastic wave formation and thermal. softening effects. The possibility
  • Nonthermal Food Processing Is Heating Up
    sterilization, scientists are exploring alternative treatments for lowering foodborne pathogen levels. Today, new technologies that are faster, cheaper, and less disruptive to quality than traditional thermal processing are increasingly common. Under the guidance of research leader Howard Zhang
