Battery Cell Assembly SPM

How this press is built

Engineered around heavy structural columns, the Battery Cell Assembly SPM provides 494 Ton of stable compaction power for precision-compacted battery electrode sheets and cell sub-assemblies in envelopes up to Electrode foil envelope up to 300 × 300 mm with ±2 µm thickness control. The hydraulic controller manages ram acceleration, powder densification, and a 102-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 battery electrode active powder formulations and dry-battery compounds, 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

Bolsters feature precision-milled DIN standard T-slots and central ejector clearance openings. Hard-chrome plated guide pillars (50 µm layer, 60 HRC) ride within self-lubricating phosphor bronze guide bushes with spiral oil grooves, ensuring long-term punch concentricity for precision-compacted battery electrode sheets and cell sub-assemblies dies.

Sizing and machine selection

Choosing the 494 Ton Battery Cell Assembly SPM 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

Quality benchmarks include laser-guided platen alignment verification, hydraulic overpressure relief testing, safety circuit validation, and trial compaction of sample parts with density analysis before shipment.

Installation and commissioning

Installation documentation includes foundation drawings, electrical panel schematics, and hydraulic piping diagrams. HEMSUN provides on-site commissioning and operator maintenance instruction.

Export packing and lead time

Export shipments include complete international documentation (Certificate of Origin, packing lists, commercial invoices), multi-voltage wiring (415V/50Hz), and robust seaworthy wooden crating for safe containerized ocean transit.

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

Standard safety features include optical light curtain arrays, concurrent two-hand cycle initiation, pilot-operated check valves against ram drop, and prominent emergency stop switches.
