Gas Spring & Damper Solutions, Co-Engineered for Your Application
Turn application dimensions, load paths and operating conditions into a documented selection, a validated prototype and a production-ready component plan.
A Gas Spring Manufacturer You Can Verify
DK controls the full production chain in-house — from material selection and force calibration to batch testing and release. These are the verifiable ranges, standards and lead times behind every order.
Materials & surface treatment
Q235 / #45 carbon steel with hard chrome plating (≥20 μm, ≥800 HV), AISI 304 and 316L stainless steel, plus QPQ and CeramPro® finishes. Food-grade NSF-H1 lubricant available.
Force & stroke range
Extension force from 10 N to 30,000 N with ±5–7% tolerance; stroke from 20 mm to 800 mm. Micro series from 5 N with an 8 mm rod.
MOQ & ordering
No MOQ on standard stock items; custom sizes from 10 pcs. Typical annual volume per specification: 500–5,000 pcs.
Quality system
ISO 9001:2015 certified quality system, automotive-grade IATF 16949 processes, and APQP / PPAP documentation on request.
Testing methods
Four-point force testing (F1–F4), 100,000-cycle life test, neutral salt-spray per ASTM B117, leak and pressure-retention tests, and full dimensional inspection.
Lead time
Stock configurations ship in 48–72 h; standard samples in 3–5 days; custom production series in 2–3 weeks after specification sign-off.
Factory evidence, not just claims
- Legal entity and business registration
- ISO 9001:2015 certificate with scope and validity
- Original SGS, salt-spray and RoHS test reports by series
- Documented change control and batch traceability
