Automatic PTFE Sheet Moulding Machine
Automatic PTFE Sheet Moulding Machine — Capacity Specifications, Platen Envelope & Tooling Details
The Automatic PTFE Sheet Moulding Machine by HEMSUN (Model HSE-381) delivers high-yield forming capacity for skiving sheets & slabs. Combines heavy-duty hydraulic drives, soft bottom ejection, and digital touchscreen controls for industrial processors.
Applications
- Serial compaction and forming of skiving sheets & slabs for industrial processors (Workstation Ref: APP-5781).
- Integrated die-set tooling for skiving sheets & slabs with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 26s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Engineered for high repeatability, the Automatic PTFE Sheet Moulding Machine provides 61 Ton of compaction force for skiving sheets & slabs components up to Moulded slab envelope up to 525 × 525 × 50 mm. Digital PLC timers manage a 121-second consolidation dwell, after which proportional relief valves exhaust pressure gradually to ensure safe part ejection without delamination.
Material behaviour under compaction
Operating with high volumetric fill capacity for virgin & filled PTFE fluoropolymer resin, the press applies controlled compaction force to produce high-integrity preforms. Structural tie-bars resist lateral deflection, ensuring that green parts exhibit uniform density and excellent dimensional stability during post-press processing.
Tooling and die design
Precision-ground tie pillars and bronze guide sleeves ensure exact tooling concentricity. Cavity inserts for skiving sheets & slabs are manufactured from premium cold-work die steel with micro-lapped bores to minimize surface friction during compaction.
Sizing and machine selection
Selecting the ideal Automatic PTFE Sheet Moulding Machine configuration requires evaluating component envelope, cavity layout, and hourly production quota. Our technical team calculates tonnage requirements (61 Ton rating) and prepares turnkey proposals including press, dies, and spare parts.
Quality checks and inspection
Quality assurance procedures cover ultrasonic testing of cylinder forgings, hydraulic pressure endurance runs, platen parallelism validation, and trial component pressing.
Installation and commissioning
Installation documentation includes foundation drawings, electrical panel schematics, and hydraulic piping diagrams. HEMSUN provides on-site commissioning and operator maintenance instruction.
Export packing and lead time
Export shipments include complete international documentation (Certificate of Origin, packing lists, commercial invoices), multi-voltage wiring (380V/60Hz), and robust seaworthy wooden crating for safe containerized ocean transit.
Maintenance and spare parts
Engineered for low maintenance overhead, the press features accessible hydraulic valves, visual oil level and temperature gauges, and centralized lubrication blocks. Spare seal sets and wear rings are cataloged under individual machine serial numbers.
Safety and guarding
The safety system integrates optical perimeter curtains, two-hand concurrent start controls, hydraulic ram lock valves, and emergency stop circuits wired into the main PLC.
