Graphite Spacer Press
Graphite Spacer Press — Sizing Parameters, Hydraulic Force & Multi-Cavity Tooling
The Graphite Spacer Press (Build HSE-240) from HEMSUN is built for continuous industrial forming of graphite spacer press components. Engineered with precision platen parallelism, variable pump hydraulics, recipe memory touchscreen controls, and full on-site commissioning support.
Applications
- Serial compaction and forming of graphite spacer press components for industrial processors (Workstation Ref: APP-2040).
- Integrated die-set tooling for graphite spacer press components with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on graphite compounds with controlled pressure dwell cycles from 35s to 2min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
Engineered around heavy structural columns, the Graphite Spacer Press provides 399 Ton of stable compaction power for graphite spacer press components in envelopes up to Engineered to client drawing envelope (Build HSE-339). The hydraulic controller manages ram acceleration, powder densification, and a 71-second pressure dwell. Gradual pressure dissipation protects fragile green edges during subsequent bottom-cylinder soft ejection.
Material behaviour under compaction
Optimized for cold preforming of fine-grain synthetic carbon graphite, 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 configured with precision guide bushings and robust ejector clearance apertures. Tooling sets for graphite spacer press components incorporate engineered draft angles and shrinkage compensations to achieve precise post-sinter tolerances.
Sizing and machine selection
Choosing the 399 Ton Graphite Spacer 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
Each press is certified through an extensive FAT protocol: hydraulic pressure holding tests under maximum rated load, platen parallelism laser inspection, and sample preform pressing witnessed at our factory.
Installation and commissioning
Each press is delivered with detailed installation plans, electrical schematics, and hydraulic circuit drawings. Experienced engineers provide on-site setup, calibration, and machine operation training.
Export packing and lead time
Our export department provides complete shipping documentation, customs compliance paperwork, and export packaging with corrosion-resistant barrier lining. Electricals are tailored to destination grid standards (415V/50Hz).
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 features comprise dual optical light guards, synchronized two-hand cycle activation, pilot-operated check valves preventing ram descent during power interruption, and illuminated emergency stop buttons.
