CNC machining
Valve bodies, couplings and fittings machined in-house to consistent, repeatable tolerances.
Service overview
CNC machining
Precision is where fire-fighting hardware succeeds or fails. Haofeng machines valve bodies, couplings and fittings on multi-axis CNC centres in-house, holding the tight, repeatable tolerances that sealing faces and threaded connections depend on.
Because machining stays under our own roof — not subcontracted to job shops — every batch is cut to the same programmed tolerances, with sealing surfaces and thread profiles that mate reliably, time after time. Consistent wall thickness and dimensional control are what keep valves leak-free under rated pressure.
From prototype to production volumes, we machine to GB, EN and customer drawings, and certify the result with dimensional records — turning "tight tolerance" from a claim into something a buyer can verify.
