Ceramic Rod Press

How this press is built

Engineered to achieve void-free internal structure in solid extruded & moulded rods (Diameter Ø 15 mm to Ø 110 mm, compaction length 400–1000 mm), the Ceramic Rod Press utilizes a heavy-duty 622 Ton hydraulic frame with variable-frequency motor control. The ram advances swiftly to the powder contact point, then switches automatically to tonnage mode, applying uniform consolidation across a 130-second dwell cycle. Decompression is metered through proportional relief valving to eliminate tensile stress rebounds, after which a bottom-mounted stripper assembly lifts the part cleanly from the die.

Material behaviour under compaction

Calibrated specifically for compaction of technical ceramic alumina (96–99.7%) and zirconia powder, 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 solid extruded & moulded rods are heat-treated in vacuum furnaces, delivering exceptional hardness and wear resistance against abrasive resins.

Sizing and machine selection

Engineers evaluating the Ceramic Rod Press should supply drawing tolerances, raw resin grade, and expected batch volume. We review hydraulic force parameters (622 Ton standard) and provide complete engineering documentation and tooling layouts.

Quality checks and inspection

Quality assurance protocols include full-pressure holding tests, ultrasonic cylinder weld inspection, platen parallelism checks across 5 bolster points, and trial sample pressing witnessed at our Dahegam works prior to dispatch.

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

The machine design simplifies servicing with accessible hydraulic manifold blocks, centralized grease lubrication points, and quick-access filter assemblies. Full spare parts backup and seal refurbishment kits are supplied from our Dahegam stock.

Safety and guarding

Plant safety compliance is ensured by optical safety barriers, two-hand cycle start controls, hydraulic burst-protection valving, and illuminated emergency stop actuators.
