PTFE Ram Extrusion Machine
PTFE Ram Extrusion Machine — Engineering Capabilities, Machine Specs & Tooling Integration
The PTFE Ram Extrusion Machine (Specification HSE-761) from HEMSUN ENGG. INDUSTRIES is engineered for tight-tolerance compaction of continuous extruded PTFE rods and thin/heavy wall tubes. Features 4-pillar column stability, closed-loop pressure dwell timing, and turnkey multi-cavity die tooling.
Applications
- Serial compaction and forming of continuous extruded PTFE rods and thin/heavy wall tubes for industrial processors (Workstation Ref: APP-6161).
- 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
Operating with 278 Ton capacity, the PTFE Ram Extrusion Machine processes continuous extruded PTFE rods and thin/heavy wall tubes within a Rod diameter Ø 5 mm to Ø 100 mm (lengths 900 / 1000 / 2000 mm) work area. Precision linear encoders coordinate pressing depth and hold load across 34 seconds. Shock-free hydraulic dumping prevents preform fracturing, allowing lower hydraulic cylinders to extract the workpiece effortlessly.
Material behaviour under compaction
The system is engineered to compact virgin and filled granular PTFE resin formulations powders with high density uniformity. Strict platen parallelism prevents density variance across parting lines, ensuring that finished parts achieve maximum tensile strength and performance.
Tooling and die design
Featuring robust tie-bar construction with bronze-bushed sliding platens, the press provides exceptional die guidance. Tooling cavities for continuous extruded PTFE rods and thin/heavy wall tubes incorporate calibrated thermal shrinkage allowances to guarantee accurate finished dimensions.
Sizing and machine selection
Sizing a PTFE Ram Extrusion Machine installation involves calculating the required pressing tonnage (278 Ton baseline) based on part cross-sectional area and material grade. Submit component STEP models and production shift volume to our engineering team for customized machine and die proposals.
Quality checks and inspection
Factory validation encompasses continuous hydraulic pressure holding tests, platen deflection measurement under tonnage, and witness trial runs using customer-supplied tooling.
Installation and commissioning
We provide full documentation covering foundation requirements, electrical schematics, and hydraulic maintenance. Factory technicians travel for on-site installation, trial compaction, and staff training.
Export packing and lead time
Export units are built with multi-voltage electrical switchgear (480V/60Hz) and heavy-duty ocean shipping packaging inside heat-treated wooden crates, supported by complete commercial and technical export documentation.
Maintenance and spare parts
Recommended servicing includes 1,000-hour hydraulic fluid checks, routine column bushing greasing, and periodic valve inspections. Complete spare seal packages are cataloged by machine serial number.
Safety and guarding
Standard safety features include optical light curtain arrays, concurrent two-hand cycle initiation, pilot-operated check valves against ram drop, and prominent emergency stop switches.
