Hydraulic Straightening Press
Hydraulic Straightening Press — Production Specifications, Cavity Tooling & Press Sizing
The Hydraulic Straightening Press (Reference HSE-703) by HEMSUN ENGG. INDUSTRIES is built for high-performance compaction of straightened drive shafts, coined coins & broached components. Features rigid platen guidance, variable-displacement hydraulics, and CMM-inspected tooling for OEM factories.
Applications
- Serial compaction and forming of straightened drive shafts, coined coins & broached components for industrial processors (Workstation Ref: APP-9703).
- Integrated die-set tooling for straightened drive shafts, coined coins & broached components with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on forming compounds with controlled pressure dwell cycles from 18s to 5min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Custom-built for high-yield manufacturing of straightened drive shafts, coined coins & broached components, this Hydraulic Straightening Press installation delivers 125 Ton of uniaxial compressive force to form Engineered to client drawing envelope (Build HSE-831) workpieces. The hydraulic power pack features high-response proportional cartridge valves that execute a rapid-advance stroke, micro-speed consolidation, and a programmed 41-second dwell curve. Regulated pressure decay guarantees stress-free preform release, while an auxiliary bottom hydraulic cylinder applies smooth ejection force to raise the finished green part without edge chipping or cavity wall friction marks.
Material behaviour under compaction
Optimized for cold preforming of high-grade engineered industrial material, the machine structure accommodates bulk volume reduction ratios between 3.2:1 and 4.2:1 with ample die fill daylight. Platen deflection is constrained under 0.04 mm/m under peak load, ensuring uniform green density distribution across both thick and thin wall sections before thermal sintering.
Tooling and die design
The press table is engineered for rapid die clamping with reinforced bolster plates. In-house manufactured punch and die sets for straightened drive shafts, coined coins & broached components utilize through-hardened tool steel with micro-honed surfaces to eliminate wall drag during ejection.
Sizing and machine selection
Our application engineers assist in configuring the Hydraulic Straightening Press by determining total projected mould area and compaction tonnage (125 Ton capacity). Send your component technical specifications for an itemized commercial and technical proposal within 24 hours.
Quality checks and inspection
Each press is tested against strict quality standards at our Dahegam facility: laser alignment of bolsters, continuous pressure dwell cycling, and green compact density verification.
Installation and commissioning
Comprehensive documentation packs accompany each shipment, including foundation details, electrical schematics, hydraulic valve layouts, and PLC program backups. Our service team offers worldwide on-site installation and commissioning.
Export packing and lead time
Export machines feature multi-voltage panels (380V/60Hz), seaworthy barrier packaging, and complete IEC shipping paperwork for container dispatch from Mundra port.
Maintenance and spare parts
Maintenance guidelines recommend hydraulic oil replacement every 2,000 hours (ISO VG 68), daily column greasing through centralized lubrication ports, and annual check of hydraulic valves. Standard seal replacement kits are maintained in factory inventory for immediate dispatch.
Safety and guarding
Comprehensive safety equipment includes dual optical light curtains, synchronized two-hand pushbuttons, hydraulic safety drop valves, and protective side mesh panels.
