Graphite Pump Seal Press
Graphite Pump Seal Press — Technical Blueprint, Machine Specifications & Tooling Sizing
The Graphite Pump Seal Press (Specification HSE-821) from HEMSUN ENGG. INDUSTRIES is engineered for tight-tolerance compaction of dynamic & static seal rings. Features 4-pillar column stability, closed-loop pressure dwell timing, and turnkey multi-cavity die tooling.
Applications
- Serial compaction and forming of dynamic & static seal rings for industrial processors (Workstation Ref: APP-2621).
- 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 16s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Engineered to achieve void-free internal structure in dynamic & static seal rings (Engineered to client drawing envelope (Build HSE-291)), the Graphite Pump Seal Press utilizes a heavy-duty 302 Ton hydraulic frame with variable-frequency motor control. The ram advances swiftly to the powder contact point, then switches automatically to tonnage mode, applying uniform consolidation across a 130-second dwell cycle. Decompression is metered through proportional relief valving to eliminate tensile stress rebounds, after which a bottom-mounted stripper assembly lifts the part cleanly from the die.
Material behaviour under compaction
Engineered to handle granular suspension resins and filled grades of fine-grain synthetic carbon graphite, the cylinder stroke and platen guidance maintain strict parallelism. Uniform uniaxial pressure distribution creates isotropic workpieces with high tensile strength and void-free dielectric resistance following oven processing.
Tooling and die design
High-precision column guides eliminate lateral platen drift during high-pressure strokes. Die components for dynamic & static seal rings are heat-treated in vacuum furnaces, delivering exceptional hardness and wear resistance against abrasive resins.
Sizing and machine selection
Our application engineers assist in configuring the Graphite Pump Seal Press by determining total projected mould area and compaction tonnage (302 Ton capacity). Send your component technical specifications for an itemized commercial and technical proposal within 24 hours.
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
Factory support includes complete foundation layouts, electrical panel diagrams, and hydraulic maintenance manuals. HEMSUN technicians provide global on-site commissioning, hydraulic fluid filling, and trial runs.
Export packing and lead time
Fully export-ready, the unit complies with international electrical standards (380V/60Hz) and features seaworthy timber crating with internal rust-inhibiting foil for transit via Mundra or Nhava Sheva container terminals.
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
Operator safety is ensured by Category 4 optical safety light curtains across the front working area, two-hand anti-tie-down cycle start pushbuttons, dual hydraulic safety drop-prevention valves, and mushroom-head emergency stop switches integrated with the main PLC control panel.
