Factory Floor, Testing Lab & QC Standards
We bridge precision manufacturing with 100% independent ground verification. Learn how our hydraulic seals, keys, and electrical sensors are produced and checked.
Precision Caliper & Micrometer Dimensional Verification
Every production batch of oil seals, dust wipers, and buffer rings undergoes critical inner/outer diameter checks with Mitutoyo 0.01mm digital calipers. We maintain an allowable tolerance window of ±0.02mm to prevent hydraulic cylinder rod scoring or bypass leakage.
- • ID / OD measurement at 3 radial points (120° apart)
- • Seal lip height & cross-sectional geometry verification
- • Hardness check (Shore A 70° / 90° durometer)

Automated Injection & Vacuum Vulcanization
Our manufacturing partners utilize modern vacuum vulcanization presses and temperature-controlled PU casting machines. This eliminates air bubbles and micro-voids inside the rubber matrix, ensuring tensile strength exceeding 20 MPa.
- • 100% virgin NBR and DuPont FKM raw polymers
- • Cleanroom packaging with anti-UV sealed polybags
- • Heat aging test: 120°C continuous for 72 hours
