Hydraulic Riveting Press

How this press is built

Designed for tight-tolerance fabrication of hydraulic riveting press components, this 728 Ton Hydraulic Riveting Press integrates closed-loop hydraulic positioning with multi-step compaction curves for parts up to Engineered to client drawing envelope (Build HSE-852). The pressing cycle maintains peak hydraulic load across a 56-second timer dwell, enabling resin particles to mechanically interlock. Programmable decompression stages prevent delamination cracking before the lower hydraulic ejector pin array raises the compacted part.

Material behaviour under compaction

Operating with high volumetric fill capacity for high-grade engineered industrial material, the press applies controlled compaction force to produce high-integrity preforms. Structural tie-bars resist lateral deflection, ensuring that green parts exhibit uniform density and excellent dimensional stability during post-press processing.

Tooling and die design

The guidance system utilizes heavy ground steel pillars with self-lubricating bronze bushings. Die sets for hydraulic riveting press components are CNC-machined in-house to tight tolerances, ensuring perfect alignment between upper punches and die cavities.

Sizing and machine selection

Configuring the 728 Ton Hydraulic Riveting Press begins with analyzing part cross-sectional geometry and production volumes. Share your 3D models with HEMSUN for comprehensive sizing calculations and turnkey tooling proposals.

Quality checks and inspection

Our manufacturing team validates every machine through comprehensive FAT runs: continuous 8-hour pressure dwell cycling, platen deflection laser profilometry, and test pressing of customer-specified sample parts.

Installation and commissioning

We supply comprehensive startup manuals, foundation drawings, electrical wiring diagrams, and spare parts lists. Field engineers provide on-site commissioning and operator instruction for seamless plant integration.

Export packing and lead time

Export shipments include complete international documentation (Certificate of Origin, packing lists, commercial invoices), multi-voltage wiring (380V/60Hz), and robust seaworthy wooden crating for safe containerized ocean transit.

Maintenance and spare parts

Service intervals require hydraulic oil filtration at 1,000-hour marks, routine tie-bar lubrication via manifold grease fittings, and seal inspections. Factory-certified replacement parts and seal overhaul packages ship on short notice.

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.
