Secondary Operations

NPM secondary operations give customers many options in completing the cycle of production. After examining the purpose of a specific part, NPM staff will suggest the necessary operations. Note that NPM can often make design or process recommendations which reduce the number of secondary operations. As a result, the customer realizes cost savings and shorter lead times.

Secondary operations may include:

  • Steam Treating - improves corrosion resistance, seals porosity, improves appearance, increases hardness and wear resistance;

  • Tumbling/Finishing - enhances appearance and controls burrs;

  • Heat Treating - increases hardness, strength and improves wear resistance;

  • Sizing - increases density, improves strength and ability to meet closer tolerances;

  • Drilling & Tapping - threads parts when required;

  • Special Handling - allows production of fragile parts;

  • Plastic Impregnating - prepares for plating and improves machine ability;

  • Plating - improves corrosion resistance and enhances physical appearance;

  • Rust Inhibiting - improves shelf life and protects from environmental conditions;

  • Vacuum Impregnating - ensures maximum oil content in the parts' natural porosity;

  • Machining - allows additional features not available in the standard process of powdered metal;

  • Assembling - makes use of multiple components in a single use product.
