PTFE Molding Machines
PTFE Molding Machines — Technical Blueprint, Machine Specifications & Tooling Sizing
Produced in Dahegam, Gandhinagar, Gujarat, India, the PTFE Molding Machines (Series HSE-489) delivers reliable high-pressure compaction for ptfe molding machines components. Features 4-column structural rigidity, digital pressure monitoring, shock-free decompression, and turnkey tooling integration for OEM processors.
Applications
- Serial compaction and forming of ptfe molding machines components for industrial processors (Workstation Ref: APP-2289).
- Integrated die-set tooling for ptfe molding machines components with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 44s to 6min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Built to satisfy strict density requirements on ptfe molding machines components (Engineered to client drawing envelope (Build HSE-383)), the PTFE Molding Machines exerts 169 Ton of force through a variable-speed hydraulic pack. The pressing program holds peak force for 109 seconds to ensure complete air evacuation. Automatic stepped decompression precedes part extraction, safeguarding component geometry against tensile cracking.
Material behaviour under compaction
The system is engineered to compact virgin & filled PTFE fluoropolymer resin 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
Precision-ground guidance columns paired with bronze sleeve bushings guarantee alignment repeatability within ±0.01 mm. Tooling sets for ptfe molding machines components are engineered with air bleeding clearances to prevent powder blow-out during rapid compaction strokes.
Sizing and machine selection
For engineering review of the PTFE Molding Machines (169 Ton series), send part drawings and daily production targets. We determine optimum platen sizes, ejection stroke, and power requirements for your facility.
Quality checks and inspection
Before dispatch, the machine undergoes extensive Factory Acceptance Testing: hydraulic circuit pressure integrity checks, tie-bar alignment verification, and trial pressing of sample parts.
Installation and commissioning
Shipments include complete technical documentation: foundation guides, electrical schematics, and hydraulic P&ID diagrams. Our engineering team assists with on-site leveling, trial pressing, and operator 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
Safety features comprise dual optical light guards, synchronized two-hand cycle activation, pilot-operated check valves preventing ram descent during power interruption, and illuminated emergency stop buttons.

Frequently Asked Questions
What PTFE moulding machine models does HEMSUN build?
Quoted gasket models include mechanical HSE-ME-GK50 (OD 10–50 mm) and HSE-ME-GK60 (OD to 60 mm), plus hydraulic CNC cells HSE20T-GK110, HSE20T-GK120, HSE25T-GK110, HSE25T-GK180, and HSE30T-GK180 for rings up to 180 mm OD. Bush, rod, and billet presses run from 6 Ton manual cells to a 500 Ton semi-auto billet press and a 600 Ton sheet press. Every machine is built to your part size and automation level.
What is the difference between fully auto and semi-auto PTFE presses?
Fully automatic cells fill PTFE powder, compress, hold under pressure, and eject without an operator in the cycle — free-flow powder is recommended for consistent auto fill. Semi-automatic cells automate compression, holding time, and ejecting; powder filling stays manual. Manual single-action presses use a push-button panel and foot switches.
Do you supply the compression die with the press?
Many CNC bush cells include a single-cavity die set with the machine. Multi-cavity bush dies, large hollow-billet cavities (for example OD 500 × ID 100 × 600 mm), and sheet dies are quoted to drawing. Presses can also ship without a die-set.
What gasket sizes can the automatic gasket machines mould?
Mechanical HSE-ME-GK50 covers OD 10–50 mm at 2–6 mm thickness (min. 4 mm wall). Hydraulic models cover OD up to 110–180 mm and thickness from about 2.5 mm to 25 mm depending on the cell. Tell us OD, ID, thickness, and required parts per hour.
