Graphite Sleeve Press

How this press is built

With an engineering rating of 152 Ton, the Graphite Sleeve Press is optimized for high-volume compaction of graphite sleeve press components across a Engineered to client drawing envelope (Build HSE-691) footprint. Dual-cylinder guidance controls platen descent, followed by progressive pressure build-up that holds for 112 seconds. A synchronized proportional relief valve vents fluid smoothly to avoid stress shear, enabling bottom-ram hydraulic ejectors to push out the intact green preform.

Material behaviour under compaction

Built to process both virgin and modified formulations of fine-grain synthetic carbon graphite, the machine delivers repeatable compaction ratios across multi-shift production. The rigid bolster structure prevents angular deflection, resulting in green parts with uniform density and minimal porosity.

Tooling and die design

High-precision column guides eliminate lateral platen drift during high-pressure strokes. Die components for graphite sleeve press components are heat-treated in vacuum furnaces, delivering exceptional hardness and wear resistance against abrasive resins.

Sizing and machine selection

When evaluating this Graphite Sleeve Press (152 Ton model), provide part dimensions, resin type, and desired shift output. We verify frame daylight, ram stroke, and hydraulic motor sizing to optimize production throughput.

Quality checks and inspection

Quality verification covers continuous hydraulic pressure holding, electrical panel insulation testing, tie-bar alignment measurement, and first-article trial pressing with density verification at our Dahegam facility.

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

Export compliance includes multi-voltage electrical switchgear (415V/50Hz), IEC documentation, and heavy-duty timber crating with anti-corrosion barrier wrapping for ocean freight.

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

Plant safety standards are met with optical perimeter light curtains, two-hand anti-tie-down control stations, hydraulic overpressure burst protection, and mechanical safety locking pins for mould maintenance.
