7 Considerations for Mechanical Seal Selection

Mechanical seals can operate for many years without issue, as long as they've been properly selected for their application. One must identify the application data (or operating conditions) to properly select the type of seal and materials of construction to ensure maximum performance from the seal over its lifetime. A Study on Strengthening Mechanical Properties of a stamping requires punch molds with improved mechanical properties in hardness, resistance to wear, and toughness. In this study, a semi-additive manufacturing (semi-AM) method of heterogeneous materials was proposed to strengthen these properties using high wear resistance steel (HWS) powder and directed energy deposition (DED) technology. A comparison of the wear resistance and hardness of two Moreover, calculating wear volume of antagonists is also valuable to interpret the wear properties of dental materials.
