COMTEC® Mfg, LLC using the conventional powdered metal or sintered metal process can offer a cost-effective alternative to other metal forming processes such as Fine Blanking, Stamping, Investment Casting, Screw Machine, Cold Forming, Die Casting, and CNC Machining. Our process offers “net shape” capability which minimizes costly post manufacturing operations or undesired process inherent nuances.
Conversion case study #1:
The existing part was a fine blanked part with full radii machined in the “lug” areas, as a costly secondary operation.
- The powdered metal conversion equivalent of this part offered the complete net shape without secondary machining operations
- No sacrificing strength
- Tooling cost of about ¼ of fine blanking
- Part cost savings of about 30%
Conversion case study #2:
The existing part was entirely machined from bar stock with very low production rates and very high part cost.
- The powdered metal conversion equivalent of this part offered a low component cost with quicker delivery
- Part cost savings of 38%
Conversion case study #3:
The existing part was produced by the zinc die casting process with relatively low material physical properties and high part cost due to the alloy low production rates.
- The powdered metal conversion equivalent of this part offered net shape form without trimming
- Cost savings on production components of 55%
- Tooling costs were 1/8 the cost of zinc die tools
Conversion case study #4:
The existing part was a hobbed spur gear with a broached keyway. Component cost was high and production rates were low.
- The powdered metal conversion equivalent of this part offered the complete net shape (same AGMA class) without any machining operations.
- Part cost savings of 40%
