Valve Core Machined Parts Product: Machined valve core components Material: Stainless steel (304, 316L) Surface Treatment: Polishing Precision Tolerance: ±0.01mm Application: Hydraulic systems In industrial manufacturing, valve cores are pivotal to fluid control. HLC Hardware selects stainless steel materials based on operational demands, verifying chemical composition, mechanical properties, and microstructure via spectrometers and hardness testers to meet ISO and ASTM standards. The machining process adheres to “roughing-finishing separation.” Lathes and milling machines remove bulk material, leaving 0.5–1mm for finishing. CNC grinders and slow wire cutting machines refine sealing surfaces to Ra0.2μm, achieve ±0.002mm tolerance on mating surfaces, and utilize 5-axis machining for complex holes. Heat treatments—carburizing, quenching, annealing—optimize material performance, validated by precision temperature control and testing. Surface treatments, including electroplating (chrome/nickel) for corrosion resistance, chemical blackening, and ultra-precision polishing, enhance durability. HLC Hardware’s stringent quality control uses calipers, micrometers, and non-destructive testing to ensure dimensional accuracy and defect-free production. Hardness testing and simulated pressure tests on sealing parts guarantee reliability. With a robust technical foundation and industry expertise, HLC Hardware leads in valve core manufacturing. Offering customized, precision-engineered solutions, continuous R&D, and a full-lifecycle service model, HLC Hardware is a trusted partner for high-quality hydraulic components.
