PTFE Hollow Ball Moulding Machine
PTFE Hollow Ball Moulding Machine — Engineering Capabilities, Machine Specs & Tooling Integration
The PTFE Hollow Ball Moulding Machine (Specification HSE-683) from HEMSUN ENGG. INDUSTRIES is engineered for tight-tolerance compaction of precision valve balls. Features 4-pillar column stability, closed-loop pressure dwell timing, and turnkey multi-cavity die tooling.
Applications
- Serial compaction and forming of precision valve balls for industrial processors (Workstation Ref: APP-2483).
- 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 28s to 5min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Operating with 337 Ton capacity, the PTFE Hollow Ball Moulding Machine processes precision valve balls within a Diameter Ø 6 mm to Ø 126 mm work area. Precision linear encoders coordinate pressing depth and hold load across 89 seconds. Shock-free hydraulic dumping prevents preform fracturing, allowing lower hydraulic cylinders to extract the workpiece effortlessly.
Material behaviour under compaction
Designed to process abrasive filled grades and virgin virgin & filled PTFE fluoropolymer resin, the press maintains high platen stiffness to guarantee uniform compaction ratios. This delivers void-free green preforms that retain precise dimensional tolerance after cooling.
Tooling and die design
Featuring robust tie-bar construction with bronze-bushed sliding platens, the press provides exceptional die guidance. Tooling cavities for precision valve balls incorporate calibrated thermal shrinkage allowances to guarantee accurate finished dimensions.
Sizing and machine selection
Sizing a PTFE Hollow Ball Moulding Machine installation involves calculating the required pressing tonnage (337 Ton baseline) based on part cross-sectional area and material grade. Submit component STEP models and production shift volume to our engineering team for customized machine and die proposals.
Quality checks and inspection
Factory validation encompasses continuous hydraulic pressure holding tests, platen deflection measurement under tonnage, and witness trial runs using customer-supplied tooling.
Installation and commissioning
Our commissioning scope includes complete circuit drawings, foundation plans, and spare seal sets. Factory engineers handle on-site installation, hydraulic startup, and comprehensive operator training.
Export packing and lead time
Configured for worldwide export, the press features custom electrical wiring (380V/60Hz), moisture-proof protective packaging, and seaworthy wooden crating for container shipping via Gujarat ports.
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
Standard safety features include optical light curtain arrays, concurrent two-hand cycle initiation, pilot-operated check valves against ram drop, and prominent emergency stop switches.
