Silicone Compression Press
Silicone Compression Press — Production Specifications, Cavity Tooling & Press Sizing
The Silicone Compression Press (Reference HSE-607) by HEMSUN ENGG. INDUSTRIES is built for high-performance compaction of silicone compression press components. Features rigid platen guidance, variable-displacement hydraulics, and CMM-inspected tooling for OEM factories.
Applications
- Serial compaction and forming of silicone compression press components for industrial processors (Workstation Ref: APP-6907).
- Integrated die-set tooling for silicone compression press components with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on rubber compounds with controlled pressure dwell cycles from 42s to 4min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Custom-built for high-yield manufacturing of silicone compression press components, this Silicone Compression Press installation delivers 407 Ton of uniaxial compressive force to form Engineered to client drawing envelope (Build HSE-757) workpieces. The hydraulic power pack features high-response proportional cartridge valves that execute a rapid-advance stroke, micro-speed consolidation, and a programmed 47-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.
Material behaviour under compaction
Because vulcanized elastomer, fluoroelastomer (FKM) & silicone rubber requires substantial compaction depth prior to sintering, the press daylight and stroke are sized to accommodate deep powder cavity charges. Precision pressure regulation ensures uniform molecular rearrangement without inducing internal shear planes or compaction voids.
Tooling and die design
Our bolster design provides generous working room for multi-cavity silicone compression press components tooling. Hardened die plates and chrome-plated guide posts ensure long operational life and prevent premature cavity wear under continuous high-tonnage cycling.
Sizing and machine selection
Our application engineers assist in configuring the Silicone Compression Press by determining total projected mould area and compaction tonnage (407 Ton capacity). Send your component technical specifications for an itemized commercial and technical proposal within 24 hours.
Quality checks and inspection
Our quality protocol includes laser-verified platen parallelism under full tonnage, digital pressure transducer calibration, and test pressing of witness samples before packing.
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
Built for global export from India, the Silicone Compression Press is wired with multi-voltage electrical configurations (380V–480V / 60Hz 3-Phase) and equipped with CE-compliant optical light curtains. Machines are packaged with VCI anti-corrosion barrier wrapping inside seaworthy wooden crates for secure container shipping from Mundra or Nhava Sheva ports.
Maintenance and spare parts
Regular upkeep involves hydraulic fluid condition monitoring, daily column guide lubrication, and inspection of cylinder seals every 12 months. All hydraulic valves and electrical components use globally standardized industrial brands for easy maintenance.
Safety and guarding
Equipment safety features comprise infrared perimeter sensors, two-hand anti-tie-down controls, hydraulic overpressure relief valves, and panel-mounted emergency stop buttons.
