Battery Electrode Compaction Press

How this press is built

At our Dahegam works, the Battery Electrode Compaction Press is built to handle continuous batch compaction of precision-compacted battery electrode sheets and cell sub-assemblies spanning Electrode foil envelope up to 300 × 300 mm with ±2 µm thickness control. The 731 Ton hydraulic system uses dual-stage pump delivery to balance high-speed idle travel with high-pressure compaction dwell lasting 35 seconds. Digital pressure transducers monitor force stability within ±1%, followed by soft hydraulic decompression that protects delicate component geometry during automated bottom-ram ejection.

Material behaviour under compaction

The system is engineered to compact battery electrode active powder formulations and dry-battery compounds powders with high density uniformity. Strict platen parallelism prevents density variance across parting lines, ensuring that finished parts achieve maximum tensile strength and performance.

Tooling and die design

Precision-ground tie pillars and bronze guide sleeves ensure exact tooling concentricity. Cavity inserts for precision-compacted battery electrode sheets and cell sub-assemblies are manufactured from premium cold-work die steel with micro-lapped bores to minimize surface friction during compaction.

Sizing and machine selection

To select the right Battery Electrode Compaction Press capacity (731 Ton standard), provide part geometry, resin grade, and automation preferences. We calculate required hydraulic tonnage and prepare complete tooling drawings.

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

Export machines feature multi-voltage panels (415V/50Hz), seaworthy barrier packaging, and complete IEC shipping paperwork for container dispatch from Mundra port.

Maintenance and spare parts

Regular upkeep involves hydraulic fluid condition monitoring, daily column guide lubrication, and inspection of cylinder seals every 12 months. All hydraulic valves and electrical components use globally standardized industrial brands for easy maintenance.

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.
