PTFE Moulding Press

How this press is built

The PTFE Moulding Press (configured under build tag HSE-114) is engineered at our Dahegam manufacturing facility for precision forming of ptfe moulding press components within a Engineered to client drawing envelope (Build HSE-679) work envelope. Operating at a calibrated pressing force of 571 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 87 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

Built to process both virgin and modified formulations of virgin & filled PTFE fluoropolymer resin, the machine delivers repeatable compaction ratios across multi-shift production. The rigid bolster structure prevents angular deflection, resulting in green parts with uniform density and minimal porosity.

Tooling and die design

Standardized platen T-slots facilitate quick tool changes on the bolster. Dedicated punch assemblies for ptfe moulding press components feature precision venting paths that allow air evacuation while retaining fine powder charges within cavity walls.

Sizing and machine selection

To evaluate the PTFE Moulding Press for your workshop, share part 2D/3D drawings, resin bulk compressibility, and power supply standards. We configure the 571 Ton press frame, platen daylight, and ejector stroke to meet your specific manufacturing targets.

Quality checks and inspection

Every production unit undergoes multi-point inspection: 8-hour continuous pressure holding, hydraulic leak testing, emergency stop circuit verification, and sample part compaction.

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

Manufactured to global standards, the machine is configured for international industrial electrical standards (415V/50Hz). Protective barrier wrapping and heavy seaworthy wooden boxing protect equipment during export shipping from Gujarat.

Maintenance and spare parts

Standard maintenance protocol includes periodic hydraulic oil testing, automated guide pillar greasing, and annual hydraulic cylinder seal replacement. Complete maintenance documentation and component cross-reference charts are provided.

Safety and guarding

Safety architecture includes Category 4 optical guards, ergonomic two-hand activation buttons, hydraulic anti-drop check valves, and manual ram locking bars for die setup.
