Shuhai Huo, Bill Heath and Dave Ryan Current applications of powder metallurgy (PM) aluminum for automotives are predominantly focused on cam caps. Metal Powder Products Company (MPP) pioneered the cam cap production and is the leading producer of the parts in the world. For moving valve-train parts, the lighter aluminum not only reduces weight […]
Shuhai Huo and William Heath High fuel cost is putting more pressure on automotive makers to further improve fuel efficiency. The direct weight reduction is regarded as one of the most economical options for improving the fuel efficiency. Direct replacement of some heavier steel engine components with lighter powder metallurgy aluminum components not only reduces […]
Howard Ferguson, MPP Director of Technology The rapid growth of P/M is primarily due to its net-shape part-making capability. In the past, the primary P/M process (compaction, sintering, and – where applicable – sizing) was sufficient for most P/M applications. However, dimensional precision has tended to steadily increase. A recent survey by the P/M industry […]
Chaman Lall, Ph.D., MPP Vice President – Technology & Applications Development and William Heath, MPP Vice President – Marketing & Business Development The growth of P/M aluminum structural parts in the automotive market is creating opportunities for lightweight alloys in cost-effective, high volume applications. Successful implementation and acceptance of aluminum cam caps by the […]
George T. Shturtz This article describes the use of powder metallurgy (P/M) for the production of close tolerance gears with strengths of up to 1240 MPa. The article describes the general process advantages (and limitations) of P/M gear manufacturing. Spur, helical, bevel, face, spur-helical, and helical-helical gears are discussed. If you would like […]
Howard Ferguson and Steven K. Smith This paper describes the manufacture of a seventeen-tooth spur gear by Precision Cold Forging (PCF) of a P/M preform to over 98% of theoretical density. This gear replaces a cut gear used in a 24hp garden tractor transmission. The method described is a bulk deformation process requiring close control […]
Chaman Lall, Ph.D., MPP VP-Mfg. & Technology Components manufactured by powder metallurgy are being used in increasingly demanding applications and environments, which dictates that the optimum performance be obtained from these materials. One aid in the achievement of this goal is the appropriate utilization of high temperature sintering. In this review, the fundamentals and […]
Gear Solutions Magazine Gear Solutions: I understand that the MPP Ford Road Division is the company’s gear specialist. Tell us a little about its history and capabilities. George Shturtz: MPP Ford Road was originally a company call Carbon City Products, which was founded in 1957 in St. Marys, Pennsylvania, so we’re celebrating our 50th anniversary […]
Chaman Lall, Ph.D., MPP Vice President – Technology & Applications Development This 160-page, softcover book introduces the subject of soft magnetism to engineers, technologists, and technical sales personnel who have responsibility for components processed by Powder Metallurgy (P/M) and Metal Injection Molding (MIM). Emphasis is placed on the practical relevance of the processing parameters […]
Chaman Lall, Ph.D., MPP Vice President – Technology & Applications Development and Mark Svilar The change from gasoline to alternate fuels such as those based on methanol, is expected to create material compatibility problems because of the enhanced reactivity of the P/M materials currently in use. These problems are most serious for the steels containing […]
