Flat Rectangular Plates and Long Bars With Alloy Steel Machined Blocks

Hydraulic manifolds, pump valve bodies, and engine fixtures use alloy steel machined blocks with flat reference surfaces that must be perpendicular, parallel, and smooth enough to seal or register mating components; surface grinding tolerance drives the assembly outcome. Chenlong Group mills and surface-grinds alloy steel machined blocks and rectangular flat plates in Lishui, with face flatness and squareness held per your drawing callouts at a facility established in 1985, supporting shipbuilding, drones, and agricultural machinery projects. IATF 16949, ISO 9001, ISO 14001, and ISO 45001 certifications at Chenlong's 30,000 m² of production space Zhejiang facility govern in-process dimensional records and material production traceability for automotive, hydraulic, pump, drone, and motorsport applications. 5-axis milling, EDM, and gear forming are available in-house.
