PTFE Bush Moulding Machine
PTFE Bush Moulding Machine — Sizing Parameters, Hydraulic Force & Multi-Cavity Tooling
The PTFE Bush Moulding Machine (Build HSE-390) from HEMSUN is built for continuous industrial forming of cylindrical bearing bushes. Engineered with precision platen parallelism, variable pump hydraulics, recipe memory touchscreen controls, and full on-site commissioning support.
Applications
- Serial compaction and forming of cylindrical bearing bushes for industrial processors (Workstation Ref: APP-8490).
- Integrated die-set tooling for cylindrical bearing bushes with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on ptfe compounds with controlled pressure dwell cycles from 35s to 2min.
- 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 Bush Moulding Machine provides 130 Ton of stable compaction power for cylindrical bearing bushes in envelopes up to Outer Diameter 20 mm to 250 mm, length up to 380 mm. The hydraulic controller manages ram acceleration, powder densification, and a 70-second pressure dwell. Gradual pressure dissipation protects fragile green edges during subsequent bottom-cylinder soft ejection.
Material behaviour under compaction
Tailored for high compressibility demands of virgin & filled PTFE fluoropolymer resin, the machine provides deep cavity clearance and smooth ram descent. Uniform pressure distribution minimizes internal stress concentrations, preventing micro-cracking during processing.
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 cylindrical bearing bushes.
Sizing and machine selection
Choosing the 130 Ton PTFE Bush 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
We supply comprehensive startup manuals, foundation drawings, electrical wiring diagrams, and spare parts lists. Field engineers provide on-site commissioning and operator instruction for seamless plant integration.
Export packing and lead time
The machine is prepared for international export with destination-specific electrical wiring (415V/50Hz), seaworthy packaging, and comprehensive IEC shipping documentation from our Gujarat manufacturing hub.
Maintenance and spare parts
The press features low-maintenance engineering with easily accessible filter elements, centralized lubrication lines, and standard industrial valves. Spare parts and seal kits ship directly from our works.
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.
