PM Valve Guide Press

How this press is built

The PM Valve Guide Press (configured under build tag HSE-442) is engineered at our Dahegam manufacturing facility for precision forming of pm valve guide press components within a Engineered to client drawing envelope (Build HSE-469) work envelope. Operating at a calibrated pressing force of 506 Ton, the hydraulic manifold incorporates a variable-displacement piston pump paired with proportional pressure modulation to govern rapid downward approach (up to 120 mm/s), smooth final compaction (5–12 mm/s), and a controlled pressure hold of 38 seconds under full tonnage. Stepped hydraulic decompression avoids sudden fluid shock, preventing internal cleavage lines from developing within fragile green compacts before lower-cylinder soft ejection occurs.

Material behaviour under compaction

Designed around the physical compressibility of sintered metal powder metallurgy alloy, this press handles standard free-flow and fine-cut resin grades. Rigid column construction prevents platen tilting during compaction, ensuring that preforms maintain consistent cross-sectional density and predictable sintering shrinkage factors.

Tooling and die design

The press table is engineered for rapid die clamping with reinforced bolster plates. In-house manufactured punch and die sets for pm valve guide press components utilize through-hardened tool steel with micro-honed surfaces to eliminate wall drag during ejection.

Sizing and machine selection

For customized quotation of this 506 Ton PM Valve Guide Press, 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

Each press is tested against strict quality standards at our Dahegam facility: laser alignment of bolsters, continuous pressure dwell cycling, and green compact density verification.

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

Our export department provides complete shipping documentation, customs compliance paperwork, and export packaging with corrosion-resistant barrier lining. Electricals are tailored to destination grid standards (415V/50Hz).

Maintenance and spare parts

Preventative maintenance includes 1,000-hour oil filtration checks, regular bronze bushing lubrication, and periodic hydraulic cylinder pressure testing. Spare seal kits, solenoid cartridges, and replacement filter elements are available directly from HEMSUN.

Safety and guarding

Comprehensive safety equipment includes dual optical light curtains, synchronized two-hand pushbuttons, hydraulic safety drop valves, and protective side mesh panels.
