Producing a consistent Hot Forging For Brass Valve begins before the furnace lights up. In our plant, every stage is governed by a measured workflow that balances raw-material traceability, die longevity, and post-forge verification.
Brass billets arrive with mill certificates confirming Cu 58–61 %, Pb 1.6–2.5 %, and Fe ≤ 0.3 %. A handheld XRF scanner samples each coil to verify chemistry; any deviation triggers quarantine. Billets are then cut to length by a cold saw with ±0.5 mm tolerance to ensure uniform mass for each forging cycle.
Heating is carried out in a continuous induction furnace set to 750 °C ± 10 °C. Optical pyrometers feed temperature data to the PLC; if the reading drifts, the billet is automatically diverted to a cooling conveyor. This step prevents overheating that could embrittle the alpha-beta phase.
Die design is modular. A master die set accepts interchangeable inserts for ½-inch through 2-inch valve bodies. Finite-element analysis predicts flash thickness and die stress; cooling channels are drilled conformally to maintain die temperature below 350 °C, extending insert life past 50 000 shots.
Forging itself takes place on a 400-ton servo press. Ram speed is profiled—fast approach, slow forming, rapid retract—to minimise die wear while achieving complete die fill. Load cells monitor peak force; any anomaly triggers an automatic reject gate.
After forging, parts drop onto a controlled conveyor and enter a 350 °C stress-relief oven for 45 minutes. This step equalises residual stresses and stabilises dimensions before machining. CNC turning then removes only 0.7 mm of stock on sealing faces, preserving the forged grain flow.
Final testing includes 100 % dimensional gauging with air gauges that confirm ±0.05 mm bore tolerance. Hydrostatic testing at 24 bar for 60 seconds verifies leak-tight integrity. Each valve is laser-etched with a heat number and boxed in recycled pulp trays, completing a traceable Hot Forging For Brass Valve supply chain ready for global shipment.
