This custom hydraulic valve plunger is precision fabricated by CNC Swiss Turning equipment as an experienced OEM custom manufacturer, adopting high-quality 304 stainless steel as raw material. The part features multi-step stepped outer diameter and concentric stepped through inner hole with smooth seamless outer cylindrical surface to ensure tight sealing during fluid switching. After full CNC Swiss Turning forming, all finished parts go through strict degreasing & alkaline cleaning to remove residual machining oil, followed by chemical passivation treatment to boost stainless steel’s anti-rust & corrosion resistance. Our factory delivers flexible custom service to revise overall length, outer dimension, inner bore diameter and surface treatment solution based on global clients’ technical drawings or physical samples for diverse industrial fluid control valve assembly projects.

- Medical fluid delivery equipment & small industrial pipeline check valve inner core
As a professional OEM custom manufacturer, our all-round custom service covers below items:
- OEM dimensional customization: Modify total length, stepped outer/inner bore sizes according to customer drawings or physical samples
- Material alternative customization: Replace 304 stainless with 316 stainless, carbon steel or alloy steel upon working fluid environment demand
- Surface treatment adjustment: Swap passivation to electropolishing, bright polishing or other anti-corrosion finishes via custom service
- Structure customization: Change through bore into blind hole structure or adjust step layout as customer design
- Small batch trial order & large volume mass production support for global importers and equipment manufacturers.
- High-precision CNC Swiss Turning with ±0.015mm tolerance eliminates poor concentricity issue, preventing fluid leakage caused by loose fit during plunger reciprocating movement
- 304 stainless steel + passivation finish solves rust & corrosion failure under long-term humid/oily hydraulic working medium, extending valve service lifespan
- Smooth seamless outer surface avoids scratch damage to valve housing inner wall during repeated sliding, reducing abnormal stuck plunger failure
- Accurate stepped inner through hole ensures stable fluid flow rate, solving inconsistent flow control trouble of finished valves
- Uniform post-process degreasing cleaning removes residual machining oil, preventing medium contamination caused by leftover cutting fluid inside hydraulic pipeline.
- Incoming raw material inspection for 304 stainless steel chemical composition and hardness before production start
- In-process periodic dimensional testing during CNC Swiss Turning to control critical tolerance within ±0.015mm
- Concentricity inspection for stepped inner & outer bore via precision measuring instrument after machining
- Final appearance check to confirm full degreasing and complete passivation coverage without incomplete processing
- Random sample anti-corrosion spot test before shipment for all OEM custom valve plunger orders.
