PTFE Ball Moulding Machine
PTFE Ball Moulding Machine — Technical Profile, Hydraulic Specifications & Tooling Sizing
Manufactured in Dahegam, Gujarat, the PTFE Ball Moulding Machine (Series HSE-216) delivers precision force for precision valve balls. Incorporates heavy bolster frames, digital dwell timers, and complete international shipping preparation.
Applications
- Serial compaction and forming of precision valve balls for industrial processors (Workstation Ref: APP-8316).
- Integrated die-set tooling for precision valve balls with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 41s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
Our PTFE Ball Moulding Machine production unit combines 273 Ton of rigid 4-column clamping force with specialized hydraulic circuitry designed for precision valve balls in dimensions up to Diameter Ø 28 mm to Ø 88 mm. The primary cylinder executes multi-stage compaction: fast ram approach, precision powder pre-compaction, and a sustained dwell phase of 29 seconds to bleed out microscopic air pockets. Following compaction, smooth electronic decompression takes place over 3–5 seconds before lower knock-out pins elevate the green preform for automated pickup.
Material behaviour under compaction
The machine mechanics are tailored for processing virgin & filled PTFE fluoropolymer resin compounds containing specialized fillers. Balanced hydraulic force delivery ensures homogeneous filler distribution, eliminating density gradients that cause component warpage in subsequent sintering cycles.
Tooling and die design
The guidance system utilizes heavy ground steel pillars with self-lubricating bronze bushings. Die sets for precision valve balls are CNC-machined in-house to tight tolerances, ensuring perfect alignment between upper punches and die cavities.
Sizing and machine selection
For customized quotation of this 273 Ton PTFE Ball Moulding Machine, please provide part CAD files, material filler percentage, and target shift output. We calculate hydraulic cylinder dimensions, bolster clearances, and power pack ratings to ensure optimal production efficiency.
Quality checks and inspection
Every machine undergoes rigorous inspection at our Gujarat manufacturing plant: an 8-hour continuous hydraulic pressure endurance run, platen parallelism laser verification under full load, and trial pressing of witness samples with green density measurement before factory sign-off.
Installation and commissioning
Documentation provided includes foundation anchoring plans, electrical circuit schematics, and hydraulic piping layouts. HEMSUN service personnel travel worldwide for machine positioning, hydraulic oil charging, and staff training.
Export packing and lead time
Engineered for international export markets, this press features dual-frequency electrical panels (415V/50Hz), IEC documentation, and seaworthy timber packaging with moisture-barrier wrapping for ocean freight through major Indian ports.
Maintenance and spare parts
Service intervals require hydraulic oil filtration at 1,000-hour marks, routine tie-bar lubrication via manifold grease fittings, and seal inspections. Factory-certified replacement parts and seal overhaul packages ship on short notice.
Safety and guarding
Comprehensive safety equipment includes dual optical light curtains, synchronized two-hand pushbuttons, hydraulic safety drop valves, and protective side mesh panels.
