PTFE Seal Moulding Machine
PTFE Seal Moulding Machine — Production Specifications, Cavity Tooling & Press Sizing
The PTFE Seal Moulding Machine (Reference HSE-707) by HEMSUN ENGG. INDUSTRIES is built for high-performance compaction of dynamic & static seal rings. Features rigid platen guidance, variable-displacement hydraulics, and CMM-inspected tooling for OEM factories.
Applications
- Serial compaction and forming of dynamic & static seal rings for industrial processors (Workstation Ref: APP-3407).
- Integrated die-set tooling for dynamic & static seal rings with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 22s 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 dynamic & static seal rings, this PTFE Seal Moulding Machine installation delivers 121 Ton of uniaxial compressive force to form Engineered to client drawing envelope (Build HSE-787) workpieces. The hydraulic power pack features high-response proportional cartridge valves that execute a rapid-advance stroke, micro-speed consolidation, and a programmed 53-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
Calibrated specifically for compaction of virgin & filled PTFE fluoropolymer resin, the hydraulic ram ensures steady force application to achieve optimal particle interlocking. Generous bolster daylight accommodates large powder fill heights without compromising platen alignment under continuous multi-shift operations.
Tooling and die design
Our bolster design provides generous working room for multi-cavity dynamic & static seal rings 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 PTFE Seal Moulding Machine by determining total projected mould area and compaction tonnage (121 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
Factory support includes complete foundation layouts, electrical panel diagrams, and hydraulic maintenance manuals. HEMSUN technicians provide global on-site commissioning, hydraulic fluid filling, and trial runs.
Export packing and lead time
Fully export-ready, the unit complies with international electrical standards (380V/60Hz) and features seaworthy timber crating with internal rust-inhibiting foil for transit via Mundra or Nhava Sheva container terminals.
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
Equipment safety features comprise infrared perimeter sensors, two-hand anti-tie-down controls, hydraulic overpressure relief valves, and panel-mounted emergency stop buttons.
