Somers Forge has built a reputation for precision engineered hydraulic press forgings that meet demanding industrial standards. These components combine tight tolerances with optimized grain flow, delivering strength and reliability where standard cast or machined parts fall short.
Across North America and Europe, manufacturers rely on Somers Forge hydraulic press forgings to reduce scrap, extend tool life, and streamline production. The controlled process supports complex shapes and critical performance in demanding environments.
| Forging Method | Typical Temperature | Key Strength Benefit | Common Applications |
|---|---|---|---|
| Open Die Hydraulic Press | 1100–1250°C | High impact toughness | Mining, power transmission |
| Closed Die Precision Press | 950–1150°C | Near net shape, tighter tolerances | Automotive, aerospace |
| Upset Forging | 1000–1200°C | Increased diameter strength | Shafts, bolts, bearing rings |
| Roll Ring Rolling | 1100–1250°C | Uniform circular grain structure | Flanges, rings, heavy cylinders |
Material Selection and Alloy Chemistry in Hydraulic Press Forgings
Low Alloy and High Strength Steel Grades
Somers Forge selects low alloy steels with molybdenum and chromium to balance hardenability and ductility. These materials respond well to hydraulic press deformation, producing fine pearlite and bainite structures under controlled cooling.
Heat Treatment and Microstructure Control
Post-forging heat treatment refines grain boundaries and relieves stress. Austempering and tempered martempering are common, delivering consistent hardness, impact resistance, and dimensional stability across large batches.
Design for Manufacturability Guidelines
Optimizing Shapes for Press Capacity
Designers at Somers Forge recommend avoiding sharp corners and abrupt section changes. Radii at transitions improve fill, reduce die wear, and ensure uniform mechanical properties throughout the forging.
Draft and Tolerance Considerations
Appropriate draft angles and generous tolerances lower forging pressure and extend die life. Close tolerances are achievable, but balanced with tool durability and overall cost efficiency.
Process Capabilities and Quality Assurance
Press Force, Die Design, and Automation
Advanced hydraulic systems apply precise force profiles, enabling complex shapes with minimal flash. Integrated gauging and trim stations support high throughput without sacrificing inspection rigor.
Testing, Certification, and Traceability
Every lot undergoes ultrasonic testing, hardness checks, and dimensional verification. Material traceability and compliance documentation meet aerospace, energy, and automotive quality requirements.
Production Optimization and Long Term Value
- Select alloys and heat treatments matched to load cycles and environmental exposure.
- Collaborate early on geometry to leverage hydraulic press forging advantages and minimize costly redesign.
- Implement robust process controls and in process monitoring for consistent quality.
- Evaluate total cost of ownership, including scrap reduction, tool life, and assembly efficiency.
