PTFE Skiving Machine — Machine Specifications, Tool Steel Dies & Operating Parameters

Fabricated at our Gujarat facility, the PTFE Skiving Machine (Series HSE-172) offers precision pressing force for skiving sheets & slabs. Built with ground bolster plates, proportional hydraulics, and PLC recipe storage for domestic and overseas plants.

Applications

  • Serial compaction and forming of skiving sheets & slabs for industrial processors (Workstation Ref: APP-1072).
  • 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 27s 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 Skiving Machine applies 357 Ton of rigid compressive force to produce skiving sheets & slabs (Moulded slab envelope up to 451 × 451 × 50 mm). A variable displacement hydraulic circuit accelerates cycle times while maintaining a steady 37-second dwell under load. Regulated pressure bleed-off eliminates internal cleavage stresses prior to automated part ejection.

Material behaviour under compaction

The press frame and stroke geometry are specifically matched to virgin & filled PTFE fluoropolymer resin characteristics, accommodating loose powder volumetric compression up to 4:1. High structural rigidity minimizes frame flexing under full load, preventing density variations that could otherwise cause out-of-round distortion during high-temperature coalescing.

Tooling and die design

Featuring robust tie-bar construction with bronze-bushed sliding platens, the press provides exceptional die guidance. Tooling cavities for skiving sheets & slabs incorporate calibrated thermal shrinkage allowances to guarantee accurate finished dimensions.

Sizing and machine selection

When specifying this 357 Ton PTFE Skiving Machine system, key inputs include part diameter/height, powder bulk density, and desired cycle automation. Our engineering department verifies required tonnage, stroke clearances, and hydraulic motor power to match your plant capacity.

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 support includes complete foundation guidelines, electrical hookup schematics, hydraulic circuit drawings, and on-site engineering assistance from Gujarat factory specialists for machine commissioning and operator instruction.

Export packing and lead time

Prepared for global destinations, the unit includes tailored electrical configurations (415V/50Hz), protective ocean crating, and complete commercial export documentation.

Maintenance and spare parts

Upkeep protocols specify hydraulic fluid replacement at 2,000 hours, routine guide post greasing, and seal evaluations. Replacement valves and seal packages ship promptly from our Gujarat facility.

Safety and guarding

Operator protection is achieved through dual-channel infrared curtains, anti-tie-down pushbuttons, hydraulic counterbalance fall-prevention valves, and interlocked perimeter guarding.

Frequently Asked Questions

What billet size does the PTFE skiving machine take?

A quoted CNC skiving cell takes sintered hollow billets up to 300 mm OD, 100 mm ID, and 300 mm width. Sheet thickness is 0.20 mm to 4.00 mm at up to 300 mm width. Larger or smaller cells are designed to your billet and sheet range.

How do you keep skived PTFE sheet uniform?

Servo-synchronised spindle speed (1–10 RPM) and ball-screw tool feed on linear guides are designed to limit waviness and banana effect. A winding spool and multi-roller guide take up the sheet. One mandrel (min. 100 mm) and one cutting tool ship with the machine.

Do you only build this 300 mm skiving size?

No. The 300 mm cell is a quoted example. HEMSUN designs PTFE skiving machines to the billet OD, ID, width, sheet thickness, and take-up method you specify.
