PTFE Insulator Moulding Machine
PTFE Insulator Moulding Machine — Sizing Parameters, Hydraulic Force & Multi-Cavity Tooling
The PTFE Insulator Moulding Machine (Build HSE-236) from HEMSUN is built for continuous industrial forming of high-voltage ceramic insulators. Engineered with precision platen parallelism, variable pump hydraulics, recipe memory touchscreen controls, and full on-site commissioning support.
Applications
- Serial compaction and forming of high-voltage ceramic insulators for industrial processors (Workstation Ref: APP-7436).
- Integrated die-set tooling for high-voltage ceramic insulators with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 31s to 3min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (415V/50Hz) and complete FAT documentation.
How this press is built
Engineered around heavy structural columns, the PTFE Insulator Moulding Machine provides 113 Ton of stable compaction power for high-voltage ceramic insulators in envelopes up to Engineered to client drawing envelope (Build HSE-969). The hydraulic controller manages ram acceleration, powder densification, and a 109-second pressure dwell. Gradual pressure dissipation protects fragile green edges during subsequent bottom-cylinder soft ejection.
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
Equipped with heavy-duty bolster plates with standardized T-slot spacing, the press accepts quick-change die assemblies. Mirror-polished die cavities (Ra ≤ 0.15 µm) and precision lower punch sleeves ensure effortless part release for high-voltage ceramic insulators.
Sizing and machine selection
Choosing the 113 Ton PTFE Insulator Moulding Machine requires assessing component dimensions, wall thickness, and shift quotas. Our technical department prepares customized proposals covering machine, dies, and FAT testing.
Quality checks and inspection
Inspection at our works includes laser measurement of platen parallelism under load, continuous hydraulic pressure testing over 8 hours, and witness trial compaction with certified green density reports.
Installation and commissioning
HEMSUN ENGG. INDUSTRIES supplies complete electrical schematics, hydraulic P&ID diagrams, foundation anchoring templates, and spare seal kits. Our field service engineers provide on-site installation, hydraulic oil charging (ISO VG 68), commissioning, and comprehensive machine operator training worldwide.
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
Plant safety standards are met with optical perimeter light curtains, two-hand anti-tie-down control stations, hydraulic overpressure burst protection, and mechanical safety locking pins for mould maintenance.
