Secondary Operations
Secondary Operations for powder metallurgy parts at Atlas are value-added processes available both in-house and through our relationships with well-established and certified partners.
Repressing
| Secondary Operation | Typical Parts | Objectives |
| Coining Objective | All | Densification, dimensional control. |
| Sizing | All | Dimensional control. |
Impregnation
| Secondary Operation | Typical Parts | Objectives |
| Resin | Structural | Improve machinability. Prepare surface for plating with other metals. Seal parts gas or liquid tight. |
Heat Treating
| Secondary Operation | Typical Parts | Objectives |
| Quench and Temper | Ferrous Structural | Improve strength and hardness. |
| Steam Treat | Ferrous | Make surface hard and wear resistant. Improve corrosion resistance and seal porosity. Provides a black/blue surface appearance for coloration needs. |
Machining
| Secondary Operation | Typical Parts | Objectives |
| Drill and Tap | All | To install set or assembly screws. |
| Turning | All | Machine to exact tolerances. Form undercuts not possible with punch and die tooling. |
| Milling | All | Form undercuts or slots. |
| Grinding | All | Remove stock, make faces parallel, and improve surface finish and tolerances. |
| Honing | All | Improved dimensional control. |
Finishing
| Secondary Operation | Typical Parts | Objectives |
| Deburring | All | Smooths edges related to parting lines. |
| Burnishing | Ferrous Structural | Ball size, roller burnish for size control and surface finish. |
| Coating Oil Dip | Ferrous | Corrosion resistance. Lubrication |
| Copper, Nickel Zinc Plating | Ferrous | Corrosion resistance, appearance. |
| Welding | Ferrous, 6.8 g/cm min. density | Makes assemblies from two or more parts. |
| Black Oxide | Ferrous, resin impregnated | Corrosion resistance, paint base. |
| Mechanical Surface Treatments: Glass Beading Wire Brush, Sanding | All | Clean, improve surface. |
| Coating | Ferrous | High corrosion resistance. |
| Tumbling/ Vibratory Finishing, Grit Blasting | All | Improve surface fatigue life. |

testimonials
“After finding Atlas Pressed Metal on the internet and a site visit by our CEO, we were impressed with the Atlas plant, the team and the product. We used them for a powdered metal part for one of our customers and we have continued to use them for about 5 years. We are pleased with their expertise in making good suggestions and with their customer service.”
