Graphite Washer Press

How this press is built

This specialized 789 Ton Graphite Washer Press system is tailored for serial manufacturing of thrust washers & disc spacers conforming to Engineered to client drawing envelope (Build HSE-311). The cycle begins with rapid gravity approach, transitions smoothly into hydraulic consolidation, and sustains full tonnage for 105 seconds. Multi-stage electronic venting prevents compaction bursts, ensuring flawless component release via bottom knockout actuators.

Material behaviour under compaction

Calibrated specifically for compaction of fine-grain synthetic carbon graphite, the hydraulic ram ensures steady force application to achieve optimal particle interlocking. Generous bolster daylight accommodates large powder fill heights without compromising platen alignment under continuous multi-shift operations.

Tooling and die design

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

Sizing and machine selection

To select the right Graphite Washer Press capacity (789 Ton standard), provide part geometry, resin grade, and automation preferences. We calculate required hydraulic tonnage and prepare complete tooling drawings.

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

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

Routine upkeep is streamlined with accessible manifold blocks, fluid level indicators, and central lubrication points. We maintain factory inventory of replacement seal sets and electrical components.

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.
