Graphite Mechanical Seal Press
Graphite Mechanical Seal Press — Machine Sizing, Hydraulic Circuitry & Cavity Tooling
Designed and built at our Dahegam engineering works, the Graphite Mechanical Seal Press (Identifier HSE-806) provides automated pressing capacity for dynamic & static seal rings. Equipped with precision-ground tie-bars, proportional load control, multi-cavity tooling, and full international export compliance.
Applications
- Serial compaction and forming of dynamic & static seal rings for industrial processors (Workstation Ref: APP-9806).
- Integrated die-set tooling for dynamic & static seal rings with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on graphite compounds with controlled pressure dwell cycles from 31s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
The Graphite Mechanical Seal Press applies 561 Ton of rigid compressive force to produce dynamic & static seal rings (Engineered to client drawing envelope (Build HSE-284)). A variable displacement hydraulic circuit accelerates cycle times while maintaining a steady 21-second dwell under load. Regulated pressure bleed-off eliminates internal cleavage stresses prior to automated part ejection.
Material behaviour under compaction
Tailored for high compressibility demands of fine-grain synthetic carbon graphite, 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
Precision-ground tie pillars and bronze guide sleeves ensure exact tooling concentricity. Cavity inserts for dynamic & static seal rings are manufactured from premium cold-work die steel with micro-lapped bores to minimize surface friction during compaction.
Sizing and machine selection
Choosing the 561 Ton Graphite Mechanical Seal 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
Our quality protocol includes laser-verified platen parallelism under full tonnage, digital pressure transducer calibration, and test pressing of witness samples before packing.
Installation and commissioning
Delivered with full engineering documentation: foundation layout, electrical schematics, hydraulic maintenance guides, and spare seal kits. Experienced HEMSUN technicians travel to your plant for turnkey setup and operator training.
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
Safety architecture includes Category 4 optical guards, ergonomic two-hand activation buttons, hydraulic anti-drop check valves, and manual ram locking bars for die setup.
