Metal Parts Manufacturer with Precision Custom Components

Custom metal parts are made through powder metallurgy by compacting metal powders in precision tooling, then sintering at high temperatures. Sterling Sintered Technologies offers complete in-house capabilities including tooling design and manufacturing, part production using 24+ compaction presses, and secondary processes like heat treatment, machining, plating, and assembly. The process produces near-net shape components with 97% material utilization, reducing costs and machining requirements while achieving tight tolerances.

Sterling Sintered Technologies provides comprehensive secondary processes including heat treatment for increased strength, surface platings and coatings, precision machining, oil or vacuum impregnation for self-lubricating properties, vibratory deburring, polishing, and complete assembly services. All secondary operations are performed with ISO 9001:2015 quality standards and custom process control plans for each component.

Sterling Sintered Technologies handles both prototype quantities and high-volume production runs up to 500,000 parts weekly. Our 24+ compaction presses ranging from 4 to 110 tons provide flexibility for small development runs through mass production, making powder metallurgy cost-effective across all volume levels while maintaining consistent quality and tight tolerances.

Powder metallurgy offers significant cost advantages over traditional machining through near-net shape manufacturing that requires minimal secondary operations. The process achieves 97% material utilization versus substantial waste in machining, produces complex multi-level shapes in single operations, and reduces production time. These factors combine to make powder metallurgy particularly cost-effective for medium to high volume production while meeting demanding OEM tolerances.

Sterling Sintered Technologies produces powder metal parts with densities ranging from 5.8 to 16.4 g/cc depending on material and application requirements. Stainless steel parts achieve densities up to 7.4 g/cc, copper alloys reach 8.3 g/cc, and specialized materials can achieve higher densities. Higher densities generally provide increased strength, improved mechanical properties, and better wear resistance for demanding applications.

Sterling Sintered Technologies maintains ISO 9001:2015 certification with comprehensive quality management systems including NIST traceable calibration, statistical process controls, part-specific control plans, and complete product traceability. Every component undergoes rigorous inspection with near-zero clearance tooling precision and documented quality procedures to ensure consistent production meeting demanding specifications.

In-house tooling design and manufacturing provides faster project turnaround, near-zero clearance precision, and direct collaboration between engineering and production teams. Sterling Sintered Technologies' tooling department has over 100 years of combined experience, enabling custom tool development that optimizes part geometry, reduces secondary operations, and ensures first-time quality for complex powder metallurgy components across all industries served.
