Rubber O Ring Press
Rubber O Ring Press — Machine Sizing, Hydraulic Circuitry & Cavity Tooling
Custom-engineered by HEMSUN ENGG. INDUSTRIES in Dahegam, Gujarat, the Rubber O Ring Press (Build Ref HSE-772) delivers high-tonnage compaction for backup rings & chevron packings. Features rigid column guidance, proportional hydraulic valving, digital dwell timing, and turnkey tool steel die sets for global manufacturing facilities.
Applications
- Serial compaction and forming of backup rings & chevron packings for industrial processors (Workstation Ref: APP-7072).
- Integrated die-set tooling for backup rings & chevron packings with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on rubber compounds with controlled pressure dwell cycles from 27s to 4min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
The Rubber O Ring Press delivers dedicated 709 Ton forming capacity for backup rings & chevron packings components within the Engineered to client drawing envelope (Build HSE-689) dimensional range. A high-efficiency hydraulic drive powers smooth ram closure and holds maximum preforming force for 105 seconds, allowing compressed air to escape through micro-vented tooling. Once the compaction dwell completes, an electro-hydraulic shockless decompression sequence discharges pressure before hydraulic bottom-ram ejection initiates.
Material behaviour under compaction
The press frame and stroke geometry are specifically matched to vulcanized elastomer, fluoroelastomer (FKM) & silicone rubber characteristics, accommodating loose powder volumetric compression up to 4:1. High structural rigidity minimizes frame flexing under full load, preventing density variations that could otherwise cause out-of-round distortion during high-temperature coalescing.
Tooling and die design
Platen bolsters are stress-relieved and surface-ground to ensure flat mounting surfaces for backup rings & chevron packings tooling. Precision-fitted ejector sleeves provide balanced lifting force across the entire component base.
Sizing and machine selection
When evaluating this Rubber O Ring Press (709 Ton model), provide part dimensions, resin type, and desired shift output. We verify frame daylight, ram stroke, and hydraulic motor sizing to optimize production throughput.
Quality checks and inspection
Quality verification covers continuous hydraulic pressure holding, electrical panel insulation testing, tie-bar alignment measurement, and first-article trial pressing with density verification at our Dahegam facility.
Installation and commissioning
Installation support includes complete foundation guidelines, electrical hookup schematics, hydraulic circuit drawings, and on-site engineering assistance from Gujarat factory specialists for machine commissioning and operator instruction.
Export packing and lead time
Prepared for global destinations, the unit includes tailored electrical configurations (415V/50Hz), protective ocean crating, and complete commercial export documentation.
Maintenance and spare parts
Maintenance guidelines recommend hydraulic oil replacement every 2,000 hours (ISO VG 68), daily column greasing through centralized lubrication ports, and annual check of hydraulic valves. Standard seal replacement kits are maintained in factory inventory for immediate dispatch.
Safety and guarding
Comprehensive safety provisions include optical infrared light curtains, synchronized two-hand start controls, hydraulic ram fall-prevention safety locks, and easily accessible emergency stop switches conforming to industrial safety standards.
