Optional Operations

• Repressing by coining provides densification, modifies surface shape (coining) and dimensional control
• Repressing by sizing provides dimensional control
• Impregnation through oil makes bearings self-lubricating
• Impregnation through resin improves machinability, prepares surface for plating with other metals, seals parts gas or liquid tight, and provides lubrication
• Infiltration in ferrous metals improves strength, and seals parts gas or liquid tight
• Infiltration in structural metals prepares surface for plating with other metals, and improves ductility and machinability
• Heat treating by quench and temper improves strength and hardness
• Heat treating by steam treat makes surface hard and wear resistant and improves corrosion resistance and seal porosity
• Machining

  • Drill and tap - install set screws or assembly fasteners
  • Turning - machine to exact tolerances, form undercuts or features not possible with compaction tooling
  • Milling - form undercuts or slots
  • Grinding - removes stock, make faces flat and parallel, improves surface finish and dimensional tolerances
• Finishing

  • Deburring - remove sharp edges related to punch and die tooling
  • Burnishing - Ball size, roller burnish for size control and surface finish
  • Coating Oil Dip - corrosion resistance
  • Copper, Nickel, Cadmium, Zinc, Chromium Plating - corrosion resistance and appearance
  • Welding - make assemblies from two or more parts
  • Black Oxide - corrosion resistance and paint base
  • Mechanical Surface Treatments - clean/improve surfaces
  • Shot Peening - improves surface fatigue life
