Graphite Bush Moulding Machine
Graphite Bush Moulding Machine — Hydraulic Specifications, Platen Clearances & Tooling Dies
Manufactured in Gujarat by HEMSUN ENGG. INDUSTRIES, the Graphite Bush Moulding Machine (Series HSE-759) offers reliable forming force for cylindrical bearing bushes. Incorporates heavy-duty hydraulic power packs, programmable pressure dwell cycles, CMM-verified tooling, and comprehensive operator safety interlocks.
Applications
- Serial compaction and forming of cylindrical bearing bushes for industrial processors (Workstation Ref: APP-7059).
- Integrated die-set tooling for cylindrical bearing bushes with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on graphite compounds with controlled pressure dwell cycles from 44s to 6min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
This specialized 155 Ton Graphite Bush Moulding Machine system is tailored for serial manufacturing of cylindrical bearing bushes conforming to Outer Diameter 20 mm to 225 mm, length up to 205 mm. The cycle begins with rapid gravity approach, transitions smoothly into hydraulic consolidation, and sustains full tonnage for 63 seconds. Multi-stage electronic venting prevents compaction bursts, ensuring flawless component release via bottom knockout actuators.
Material behaviour under compaction
Engineered around the rheological behavior of fine-grain synthetic carbon graphite, the machine applies balanced compaction force to establish tight molecular interlocking. Consistent preform density translates directly into superior wear and chemical resistance in service.
Tooling and die design
The platen working area incorporates CNC-machined clamping slots and precision ejector guide holes. Induction-hardened and ground tie-bars with self-lubricating bronze bushings maintain sub-millimeter die alignment during high-speed production of cylindrical bearing bushes.
Sizing and machine selection
To select the right Graphite Bush Moulding Machine capacity (155 Ton standard), provide part geometry, resin grade, and automation preferences. We calculate required hydraulic tonnage and prepare complete tooling drawings.
Quality checks and inspection
Inspection at our works includes laser measurement of platen parallelism under load, continuous hydraulic pressure testing over 8 hours, and witness trial compaction with certified green density reports.
Installation and commissioning
Our commissioning scope includes complete circuit drawings, foundation plans, and spare seal sets. Factory engineers handle on-site installation, hydraulic startup, and comprehensive operator training.
Export packing and lead time
Engineered for international export markets, this press features dual-frequency electrical panels (380V–480V/60Hz), IEC documentation, and seaworthy timber packaging with moisture-barrier wrapping for ocean freight through major Indian ports.
Maintenance and spare parts
Routine upkeep is streamlined with accessible manifold blocks, fluid level indicators, and central lubrication points. We maintain factory inventory of replacement seal sets and electrical components.
Safety and guarding
Operator protection is achieved through dual-channel infrared curtains, anti-tie-down pushbuttons, hydraulic counterbalance fall-prevention valves, and interlocked perimeter guarding.
