PTFE Bearing Moulding Machine
PTFE Bearing Moulding Machine — Technical Specifications, Tooling Architecture & Production Sizing
Engineered by HEMSUN ENGG. INDUSTRIES, the PTFE Bearing Moulding Machine (Series HSE-468) is a dedicated industrial press for backup rings & chevron packings. Combines rigid platen bolsters, high-efficiency hydraulic drive packs, automated bottom ejection, and export-ready electrical configurations.
Applications
- Serial compaction and forming of backup rings & chevron packings for industrial processors (Workstation Ref: APP-8568).
- 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 23s to 5min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
The 388 Ton PTFE Bearing Moulding Machine press configuration is purpose-built for forming backup rings & chevron packings up to Engineered to client drawing envelope (Build HSE-318). Rapid approach cylinders minimize cycle idle time, while main pressing rams deliver uniform force over a 28-second dwell. Smooth hydraulic decomp preserves green part density before lower ejector pins elevate the workpiece.
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
The press table is engineered for rapid die clamping with reinforced bolster plates. In-house manufactured punch and die sets for backup rings & chevron packings utilize through-hardened tool steel with micro-honed surfaces to eliminate wall drag during ejection.
Sizing and machine selection
To size this PTFE Bearing Moulding Machine (388 Ton class) for your manufacturing facility, provide 2D component drawings, resin specification, daily output targets, and preferred automation tier. Press force is calculated from total projected tool area multiplied by specific compaction pressure with a 20% operating safety margin.
Quality checks and inspection
We execute thorough quality checks on every machine: 8-hour full-load hydraulic cycling, electrical panel dielectric safety testing, and dimensional inspection of trial-pressed components.
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
Our export department provides complete shipping documentation, customs compliance paperwork, and export packaging with corrosion-resistant barrier lining. Electricals are tailored to destination grid standards (415V/50Hz).
Maintenance and spare parts
Routine upkeep is streamlined with accessible manifold blocks, fluid level indicators, and central lubrication points. We maintain factory inventory of replacement seal sets and electrical components.
Safety and guarding
The machine is equipped with Category 4 optical safety guards, two-hand anti-tie-down control circuits, automatic hydraulic overpressure relief valves, and perimeter mesh guarding with safety interlocks.
