PTFE Rod Extrusion Machine
PTFE Rod Extrusion Machine — Technical Specifications, Platen Dimensions & Tooling Sizing
HEMSUN ENGG. INDUSTRIES manufactures the PTFE Rod Extrusion Machine (Series HSE-971) in Dahegam, Gandhinagar, Gujarat, India for high-performance compaction and moulding of continuous extruded PTFE rods and thin/heavy wall tubes. Engineered with heavy-duty structural rigidity, programmable pressure dwell (3,000–4,500 psi / 300–500 kg/cm²), precision ejection hydraulics, and PLC touchscreen controls for domestic and export plants.
Applications
- Serial compaction and forming of continuous extruded PTFE rods and thin/heavy wall tubes for industrial processors (Workstation Ref: APP-9971).
- Integrated die-set tooling for continuous extruded PTFE rods and thin/heavy wall tubes with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ram-extrusion compounds with controlled pressure dwell cycles from 16s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Designed for tight-tolerance fabrication of continuous extruded PTFE rods and thin/heavy wall tubes, this 625 Ton PTFE Rod Extrusion Machine integrates closed-loop hydraulic positioning with multi-step compaction curves for parts up to Rod diameter Ø 5 mm to Ø 100 mm (lengths 900 / 1000 / 2000 mm). The pressing cycle maintains peak hydraulic load across a 137-second timer dwell, enabling resin particles to mechanically interlock. Programmable decompression stages prevent delamination cracking before the lower hydraulic ejector pin array raises the compacted part.
Material behaviour under compaction
Because virgin and filled granular PTFE resin formulations 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
The press table is configured with precision guide bushings and robust ejector clearance apertures. Tooling sets for continuous extruded PTFE rods and thin/heavy wall tubes incorporate engineered draft angles and shrinkage compensations to achieve precise post-sinter tolerances.
Sizing and machine selection
Configuring the 625 Ton PTFE Rod Extrusion Machine begins with analyzing part cross-sectional geometry and production volumes. Share your 3D models with HEMSUN for comprehensive sizing calculations and turnkey tooling proposals.
Quality checks and inspection
Our manufacturing team validates every machine through comprehensive FAT runs: continuous 8-hour pressure dwell cycling, platen deflection laser profilometry, and test pressing of customer-specified sample parts.
Installation and commissioning
Our commissioning package includes complete technical manuals, electrical wiring diagrams, hydraulic schematics, and on-site support by factory engineers to ensure smooth machine startup and comprehensive operator training.
Export packing and lead time
Built for global export from India, the PTFE Rod Extrusion Machine 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
Service intervals require hydraulic oil filtration at 1,000-hour marks, routine tie-bar lubrication via manifold grease fittings, and seal inspections. Factory-certified replacement parts and seal overhaul packages ship on short notice.
Safety and guarding
Operator safety is ensured by Category 4 optical safety light curtains across the front working area, two-hand anti-tie-down cycle start pushbuttons, dual hydraulic safety drop-prevention valves, and mushroom-head emergency stop switches integrated with the main PLC control panel.
