PTFE Sintering Oven With Rotating Disc
PTFE Sintering Oven With Rotating Disc — Performance Specifications, Press Tonnage & Tooling Layout
The PTFE Sintering Oven With Rotating Disc (Build HSE-972) from HEMSUN is built for continuous industrial forming of backup rings & chevron packings. Engineered with precision platen parallelism, variable pump hydraulics, recipe memory touchscreen controls, and full on-site commissioning support.
Applications
- Serial compaction and forming of backup rings & chevron packings for industrial processors (Workstation Ref: APP-2772).
- Integrated die-set tooling for backup rings & chevron packings with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 17s to 4min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
The PTFE Sintering Oven With Rotating Disc (configured under build tag HSE-672) is engineered at our Dahegam manufacturing facility for precision forming of backup rings & chevron packings within a Engineered to client drawing envelope (Build HSE-678) work envelope. Operating at a calibrated pressing force of 307 Ton, the hydraulic manifold incorporates a variable-displacement piston pump paired with proportional pressure modulation to govern rapid downward approach (up to 120 mm/s), smooth final compaction (5–12 mm/s), and a controlled pressure hold of 67 seconds under full tonnage. Stepped hydraulic decompression avoids sudden fluid shock, preventing internal cleavage lines from developing within fragile green compacts before lower-cylinder soft ejection occurs.
Material behaviour under compaction
With reinforced structural columns, the press handles high-pressure compaction of virgin & filled PTFE fluoropolymer resin without platen tilting. This ensures consistent green density across the entire cross-section, reducing shrinkage anomalies during subsequent thermal processing.
Tooling and die design
Our bolster design provides generous working room for multi-cavity backup rings & chevron packings 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
Specifying this 307 Ton PTFE Sintering Oven With Rotating Disc press involves reviewing part envelope, cavity layout, and cycle times. Contact our Dahegam engineering department with your drawings for a tailored machine quotation.
Quality checks and inspection
Quality assurance protocols include full-pressure holding tests, ultrasonic cylinder weld inspection, platen parallelism checks across 5 bolster points, and trial sample pressing witnessed at our Dahegam works prior to dispatch.
Installation and commissioning
Documentation provided includes foundation anchoring plans, electrical circuit schematics, and hydraulic piping layouts. HEMSUN service personnel travel worldwide for machine positioning, hydraulic oil charging, and staff training.
Export packing and lead time
The press is manufactured for international delivery with custom electrical voltages (415V/50Hz), robust export wooden boxing, and full customs and shipping documentation support.
Maintenance and spare parts
Maintenance requirements involve regular hydraulic oil filtration (ISO VG 68), guide post lubrication via grease nipples, and annual seal inspections. Replacement seal kits and solenoid spares are readily available.
Safety and guarding
Comprehensive safety equipment includes dual optical light curtains, synchronized two-hand pushbuttons, hydraulic safety drop valves, and protective side mesh panels.
