Hydraulic Crimping Machine

How this press is built

Our Hydraulic Crimping Machine production unit combines 77 Ton of rigid 4-column clamping force with specialized hydraulic circuitry designed for hydro-tested high-pressure pipe joints, stator cores & crimped filters in dimensions up to Component envelope up to 745 × 445 × 345 mm. The primary cylinder executes multi-stage compaction: fast ram approach, precision powder pre-compaction, and a sustained dwell phase of 57 seconds to bleed out microscopic air pockets. Following compaction, smooth electronic decompression takes place over 3–5 seconds before lower knock-out pins elevate the green preform for automated pickup.

Material behaviour under compaction

The mechanical design addresses the high volumetric reduction of engineered automotive sub-assemblies, pipe casings & electric motor cores powders by providing extended cylinder stroke lengths. Stable platen guidance prevents uneven compaction, ensuring high yield rates across production batches.

Tooling and die design

Our toolroom integrates vacuum-hardened AISI D2 steel dies (58–62 HRC) directly onto the press bolster. Precision guide columns and self-aligning ball seats prevent uneven punch wear during high-volume compaction of hydro-tested high-pressure pipe joints, stator cores & crimped filters.

Sizing and machine selection

For customized quotation of this 77 Ton Hydraulic Crimping Machine, please provide part CAD files, material filler percentage, and target shift output. We calculate hydraulic cylinder dimensions, bolster clearances, and power pack ratings to ensure optimal production efficiency.

Quality checks and inspection

Before dispatch, the machine undergoes extensive Factory Acceptance Testing: hydraulic circuit pressure integrity checks, tie-bar alignment verification, and trial pressing of sample parts.

Installation and commissioning

HEMSUN ENGG. INDUSTRIES supplies complete electrical schematics, hydraulic P&ID diagrams, foundation anchoring templates, and spare seal kits. Our field service engineers provide on-site installation, hydraulic oil charging (ISO VG 68), commissioning, and comprehensive machine operator training worldwide.

Export packing and lead time

Export compliance includes multi-voltage electrical switchgear (415V/50Hz), IEC documentation, and heavy-duty timber crating with anti-corrosion barrier wrapping for ocean freight.

Maintenance and spare parts

Preventative maintenance includes 1,000-hour oil filtration checks, regular bronze bushing lubrication, and periodic hydraulic cylinder pressure testing. Spare seal kits, solenoid cartridges, and replacement filter elements are available directly from HEMSUN.

Safety and guarding

Comprehensive safety equipment includes dual optical light curtains, synchronized two-hand pushbuttons, hydraulic safety drop valves, and protective side mesh panels.
