PTFE Sintering Oven — Performance Specifications, Press Tonnage & Tooling Layout

Designed and built at our Dahegam engineering works, the PTFE Sintering Oven (Identifier HSE-220) provides automated pressing capacity for backup rings & chevron packings. Equipped with precision-ground tie-bars, proportional load control, multi-cavity tooling, and full international export compliance.

Applications

Serial compaction and forming of backup rings & chevron packings for industrial processors (Workstation Ref: APP-7420).
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 15s to 2min.
Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.

Discuss Your Press Requirement

How this press is built

With an engineering rating of 620 Ton, the PTFE Sintering Oven is optimized for high-volume compaction of backup rings & chevron packings across a Engineered to client drawing envelope (Build HSE-230) footprint. Dual-cylinder guidance controls platen descent, followed by progressive pressure build-up that holds for 80 seconds. A synchronized proportional relief valve vents fluid smoothly to avoid stress shear, enabling bottom-ram hydraulic ejectors to push out the intact green preform.

Material behaviour under compaction

The mechanical design addresses the high volumetric reduction of virgin & filled PTFE fluoropolymer resin powders by providing extended cylinder stroke lengths. Stable platen guidance prevents uneven compaction, ensuring high yield rates across production batches.

Tooling and die design

The platen working area incorporates CNC-machined clamping slots and precision ejector guide holes. Induction-hardened and ground tie-bars with self-lubricating bronze bushings maintain sub-millimeter die alignment during high-speed production of backup rings & chevron packings.

Sizing and machine selection

Specifying this 620 Ton PTFE Sintering Oven press involves reviewing part envelope, cavity layout, and cycle times. Contact our Dahegam engineering department with your drawings for a tailored machine quotation.

Quality checks and inspection

Our Gujarat works conducts stringent quality testing on every unit: 8-hour endurance cycling under peak tonnage, hydraulic oil temperature stability monitoring, and dimensional verification of trial-pressed green compacts.

Installation and commissioning

Our commissioning package includes complete technical manuals, electrical wiring diagrams, hydraulic schematics, and on-site support by factory engineers to ensure smooth machine startup and comprehensive operator training.

Export packing and lead time

Export compliance includes multi-voltage electrical switchgear (415V/50Hz), IEC documentation, and heavy-duty timber crating with anti-corrosion barrier wrapping for ocean freight.

Maintenance and spare parts

Service procedures include periodic hydraulic oil filtering, daily bronze bushing lubrication, and annual hydraulic cylinder inspection. Factory-backed replacement seal sets are maintained in stock.

Safety and guarding

The press incorporates Category 4 infrared safety curtains, dual-hand concurrent cycle start buttons, hydraulic drop-prevention safety valves, and perimeter safety guarding with electrical interlock switches.

Frequently Asked Questions

What chamber size is the PTFE sintering oven?

A quoted oven uses a 1050 × 1050 × 1050 mm heating chamber with 950 mm trays, 21 kW total load, SS-304 inner sheet, MS outer sheet, and 6-inch insulation. Chamber size and kW rating are built to your billet load.

Is the sintering oven used with the moulding presses?

Yes. Compression-moulded PTFE billets, bushes, and gaskets are sintered in batch ovens after pressing. We can quote a press, die-set, and oven as a matched cell.
