Engineered to exact OEM configurations with IATF 16949:2016 quality guarantees
Modern vehicles demand unparalleled safety, reliability, and precision. At the heart of safety engineering lies the vehicle hydraulic braking and clutch control system. As global automotive supply chains transition towards higher efficiency, sourcing components that achieve a seamless balance between cost-efficiency and stringent safety compliance is critical. Wuhu Qiujing Auto Parts Co., Ltd. has established itself as an industry leader in manufacturing components designed to perform under critical conditions.
Braking systems operate under fluid pressures reaching up to 150 bar (15 MPa) during emergency situations. Our manufacturing facilities implement the GB/T19001-2016 / ISO 9001:2015 and IATF 16949:2016 quality management frameworks, ensuring that every master cylinder, wheel cylinder, and load-sensing proportioning valve undergoes strict testing protocol including micro-leak testing and mechanical fatigue testing.
China's automotive manufacturing industry has evolved from basic component reproduction to sophisticated, high-precision engineering. Choosing Wuhu Qiujing Auto Parts as your partner provides significant structural advantages:
As vehicle design transitions from internal combustion engines to hybrid and pure electric powertrains (EVs), secondary mechanical systems are experiencing rapid transformations:

Direct answers to technical questions commonly raised by purchasing managers and automotive engineers
For cast iron configurations, we utilize HT250 (Class 35) or ductile iron GGG40/50 to guarantee high pressure resistance. For weight-reduction programs, we employ A356-T6 or AlSi11Cu2(Fe) die-cast aluminum alloys featuring post-machining anodization treatment. This creates an oxide barrier that prevents internal oxidation caused by humidity or old brake fluid.
Every single master and wheel cylinder is subject to dual-stage pneumatic leak tests: low-pressure check (0.5 bar) to confirm basic seal lip positioning, and high-pressure check (up to 120 bar depending on component specification) to verify overall physical integrity. Our target tolerance rate is 0 PPM, maintaining high quality reliability.
Our internal R&D team works directly with client-provided CAD models (STP, IGS formats) or physical OE samples. Using high-precision coordinate measuring machines (CMM) and specialized mold design tooling, we can transition a conceptual custom configuration to prototype testing within 45 to 60 business days.
Yes, our EPDM polymer compounds are formulated for complete chemical compatibility with glycol-ether based DOT 3, DOT 4, and DOT 5.1 brake fluids. For heavy industrial machinery applications requiring mineral oil-based fluids (LHM), we can specify NBR (Nitrile) seal kits. Note: DOT 5 silicone-based fluids require specialized client confirmation.
