Railway Brake Block Press
Railway Brake Block Press — Hydraulic Specifications, Platen Clearances & Tooling Dies
Produced in Dahegam, Gandhinagar, Gujarat, India, the Railway Brake Block Press (Series HSE-811) delivers reliable high-pressure compaction for heavy vehicle and railway brake blocks. Features 4-column structural rigidity, digital pressure monitoring, shock-free decompression, and turnkey tooling integration for OEM processors.
Applications
- Serial compaction and forming of heavy vehicle and railway brake blocks for industrial processors (Workstation Ref: APP-1711).
- Integrated die-set tooling for heavy vehicle and railway brake blocks with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on thermoset-friction compounds with controlled pressure dwell cycles from 36s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
Railway Brake Block Press — process notes
Custom-built for high-yield manufacturing of heavy vehicle and railway brake blocks, this Railway Brake Block Press installation delivers 420 Ton of uniaxial compressive force to form Platen working area 601 × 601 mm with dual electric heating workpieces. The hydraulic power pack features high-response proportional cartridge valves that execute a rapid-advance stroke, micro-speed consolidation, and a programmed 112-second dwell curve. Regulated pressure decay guarantees stress-free preform release, while an auxiliary bottom hydraulic cylinder applies smooth ejection force to raise the finished green part without edge chipping or cavity wall friction marks.
Railway Brake Block Press — material behaviour
The press frame and stroke geometry are specifically matched to thermoset compounds (SMC/BMC/bakelite) & friction mix powders 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.
Railway Brake Block Press — tooling design
The guidance system utilizes heavy ground steel pillars with self-lubricating bronze bushings. Die sets for heavy vehicle and railway brake blocks are CNC-machined in-house to tight tolerances, ensuring perfect alignment between upper punches and die cavities.
Railway Brake Block Press — sizing and selection
For engineering review of the Railway Brake Block Press (420 Ton series), send part drawings and daily production targets. We determine optimum platen sizes, ejection stroke, and power requirements for your facility.
Railway Brake Block Press — quality checks
Factory acceptance testing includes an 8-hour continuous load cycle, digital pressure transducer calibration, hydraulic circuit leak-tightness inspection, and trial component compaction with CMM dimensional sign-off.
Railway Brake Block Press — 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.
Railway Brake Block Press — export and lead time
Export units are equipped with destination-compliant electricals (380V/60Hz), anti-rust barrier wrapping, and seaworthy timber boxing for secure overseas shipping.
Railway Brake Block Press — maintenance and spares
The press features low-maintenance engineering with easily accessible filter elements, centralized lubrication lines, and standard industrial valves. Spare parts and seal kits ship directly from our works.
Railway Brake Block Press — safety notes
The press incorporates Category 4 infrared safety curtains, dual-hand concurrent cycle start buttons, hydraulic drop-prevention safety valves, and perimeter safety guarding with electrical interlock switches.
