PM Valve Seat Press
PM Valve Seat Press — Machine Data, Bolster Dimensions & Die Integration
The PM Valve Seat Press from HEMSUN (Identifier HSE-755) provides dedicated compaction capacity for butterfly & ball valve seats. Built with heavy-duty 4-column structures, proportional load valving, and soft hydraulic bottom ejection.
Applications
- Serial compaction and forming of butterfly & ball valve seats for industrial processors (Workstation Ref: APP-2555).
- Integrated die-set tooling for butterfly & ball valve seats with automated powder cavity charging and synchronized bottom ejection.
- Programmable density management on pm compounds with controlled pressure dwell cycles from 40s to 2min.
- Export-compliant production line equipped with multi-voltage electrical cabinet (380V/60Hz) and complete FAT documentation.
How this press is built
Engineered to achieve void-free internal structure in butterfly & ball valve seats (Engineered to client drawing envelope (Build HSE-640)), the PM Valve Seat Press utilizes a heavy-duty 100 Ton hydraulic frame with variable-frequency motor control. The ram advances swiftly to the powder contact point, then switches automatically to tonnage mode, applying uniform consolidation across a 80-second dwell cycle. Decompression is metered through proportional relief valving to eliminate tensile stress rebounds, after which a bottom-mounted stripper assembly lifts the part cleanly from the die.
Material behaviour under compaction
Designed to process abrasive filled grades and virgin sintered metal powder metallurgy alloy, 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
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 butterfly & ball valve seats.
Sizing and machine selection
Engineers evaluating the PM Valve Seat Press should supply drawing tolerances, raw resin grade, and expected batch volume. We review hydraulic force parameters (100 Ton standard) and provide complete engineering documentation and tooling layouts.
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
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
The machine design simplifies servicing with accessible hydraulic manifold blocks, centralized grease lubrication points, and quick-access filter assemblies. Full spare parts backup and seal refurbishment kits are supplied from our Dahegam stock.
Safety and guarding
Plant safety compliance is ensured by optical safety barriers, two-hand cycle start controls, hydraulic burst-protection valving, and illuminated emergency stop actuators.
