FAQ

Q1: Can you fabricate this custom plunger shaft based on my 2D/3D drawings?

A1: Yes. We fully custom produce CNC turned shafts strictly following your drawings or sample requirements.

Q2: Which stainless steel grade is better for plunger parts with frequent movement?

A2: 316L offers superior corrosion resistance; 304 is cost-effective for general wear-resistant fluid control applications.

Q3: What surface treatment options are available for these shafts?

A3: We offer deburring, passivation, polishing or hardening treatment upon request to improve wear performance.

Q4: What drawing formats do you accept for quotation?

A4: STEP, IGES and PDF 2D engineering drawings are acceptable for technical review and pricing.

Q5: How do you inspect the precision of multi-groove plunger shafts?

A5: We use micrometers and optical measuring instruments to check critical dimensions, grooves and taper profile.

    We chose ChenRong for urgent steel CNC turning parts for our test fixture. Their rapid service saved our prototype schedule. Steel shafts and sleeves are precisely turned, surface finish is clean, dimensions match our drawing perfectly. Quotation was fast and they kept us updated on production progress. We will use their rapid turning service again.
