PM Oil Pump Gear Press
PM Oil Pump Gear Press — Engineering Profile, Hydraulic Parameters & Die Tooling
Custom-engineered by HEMSUN ENGG. INDUSTRIES in Dahegam, Gujarat, the PM Oil Pump Gear Press (Build Ref HSE-702) delivers high-tonnage compaction for powder metallurgy spur gears. Features rigid column guidance, proportional hydraulic valving, digital dwell timing, and turnkey tool steel die sets for global manufacturing facilities.
Applications
- Serial compaction and forming of powder metallurgy spur gears for industrial processors (Workstation Ref: APP-9702).
- Integrated die-set tooling for powder metallurgy spur gears with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on pm compounds with controlled pressure dwell cycles from 17s to 4min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
The 140 Ton PM Oil Pump Gear Press press configuration is purpose-built for forming powder metallurgy spur gears up to Engineered to client drawing envelope (Build HSE-291). Rapid approach cylinders minimize cycle idle time, while main pressing rams deliver uniform force over a 24-second dwell. Smooth hydraulic decomp preserves green part density before lower ejector pins elevate the workpiece.
Material behaviour under compaction
Tailored for high compressibility demands of sintered metal powder metallurgy alloy, the machine provides deep cavity clearance and smooth ram descent. Uniform pressure distribution minimizes internal stress concentrations, preventing micro-cracking during processing.
Tooling and die design
Featuring robust tie-bar construction with bronze-bushed sliding platens, the press provides exceptional die guidance. Tooling cavities for powder metallurgy spur gears incorporate calibrated thermal shrinkage allowances to guarantee accurate finished dimensions.
Sizing and machine selection
Choosing the 140 Ton PM Oil Pump Gear Press requires assessing component dimensions, wall thickness, and shift quotas. Our technical department prepares customized proposals covering machine, dies, and FAT testing.
Quality checks and inspection
Inspection at our works includes laser measurement of platen parallelism under load, continuous hydraulic pressure testing over 8 hours, and witness trial compaction with certified green density reports.
Installation and commissioning
Installation support includes complete foundation guidelines, electrical hookup schematics, hydraulic circuit drawings, and on-site engineering assistance from Gujarat factory specialists for machine commissioning and operator instruction.
Export packing and lead time
Prepared for global destinations, the unit includes tailored electrical configurations (415V/50Hz), protective ocean crating, and complete commercial export documentation.
Maintenance and spare parts
Recommended servicing includes 1,000-hour hydraulic fluid checks, routine column bushing greasing, and periodic valve inspections. Complete spare seal packages are cataloged by machine serial number.
Safety and guarding
Operator protection is achieved through dual-channel infrared curtains, anti-tie-down pushbuttons, hydraulic counterbalance fall-prevention valves, and interlocked perimeter guarding.
