Explore our custom manufactured components designed for extreme pressure tolerances, high durability, and safety-critical applications.
Established in 2016 and situated in the manufacturing hub of Shenzhen, Shenzhen Xinli Technology Co., Ltd. has forged a distinguished 9-year legacy as an industry-leading manufacturer of high-precision auto parts, safety-critical mechanical equipment parts, certified medical equipment components, and aerospace-grade structural components for agricultural manned vehicles and unmanned aerial vehicles (UAVs).
By leveraging advanced CNC turning-milling centers, multi-axis machining centers, and strict inspection setups, we deliver top-tier custom manufacturing and engineered structural solutions designed to excel under intense mechanical stresses.
Technical analysis on material science, manufacturing tolerances, regulatory standards, and supply chain strategies.
Under modern safety mandates, automotive brake lines must withstand hydraulic system pressures exceeding 150 bar (2175 psi). We utilize double-wall copper-brazed steel tubing (Bundy Tubes) conforming to standard ASTM A254. Surface coatings like PVF (Polyvinyl Fluoride) and Zinc-Alloy coatings protect against rock strikes and chemical road salts.
With the integration of electric vehicles (EVs) and autonomous systems, braking technologies have moved toward electro-hydraulic and Brake-by-Wire (BbW) platforms. This transition demands high-precision connection manifolds, lightweight brackets, and corrosion-resistant alloys like H65 brass or anodized aluminum to manage higher fluid flow rates.
Automotive brake line assemblies must meet strict standards like SAE J1401 and FMVSS 106. Every fitting, bracket, and connector we produce undergoes optical profile inspections, helium leak testing, and salt spray testing (ASTMB117 up to 1000 hours) to prevent field failures.
Designing modern hydraulic connectors requires a deep understanding of metal flow dynamics. The flare geometry—specifically double flares (SAE 45-degree) and ISO bubble flares—must be machined precisely to prevent leaks. As a specialist manufacturer based in Shenzhen, China, we ensure all hydraulic connectors and milled brackets maintain high surface finishes and zero defect margins.
A transparent look at our raw material sourcing, multi-axis machining floors, optical metrology, and packing processes.
Hydraulic braking systems operate under extreme conditions. Even minor dimensional errors in flare fittings or connector brackets can lead to micro-leaks, pressure drops, and system failures. By using multi-axis CNC machines and automated optical inspection systems, we maintain tolerances within 0.005mm. This guarantees leak-free fluid paths and reliable mechanical support for automotive braking applications worldwide.
At Shenzhen Xinli Technology Co., Ltd., our manufacturing capabilities span multiple demanding industries. In addition to automotive brake components, we specialize in high-end medical device components, non-standard industrial gear assemblies, and drone structural parts. Our expertise in machining diverse materials—including anodized aluminum, structural steel, brass, and industrial polymers—ensures we can fulfill complex, custom-engineered orders.
We work closely with clients from initial CAD design optimization to surface treatment, providing a seamless manufacturing workflow. Our focus on quality ensures all parts meet the strict durability and safety standards required by modern industries.
Reliability requires strict quality control. Our facility features coordinate measuring machines (CMM), digital optical projectors, and pressure test systems. We inspect raw materials upon arrival, conduct in-process quality audits, and perform final functional tests to ensure every component complies with technical drawings and specifications.
Answers to common engineering and sourcing questions regarding automotive hydraulic and precision milled parts.
For high-pressure hydraulic paths, we recommend double-walled brazed carbon steel tubing (ASTM A254) coated with Zinc or PVF for rust prevention, or Copper-Nickel alloys (C70600) for marine or extreme road conditions. Fitting connectors are typically machined from H65 Brass or high-tensile carbon steel (zinc nickel plated) to ensure durable, leak-free threads.
Our production workflows operate under ISO 9001:2015 certification. Our brake line and hydraulic connector parts can be customized to comply with SAE J1401 and FMVSS 106, which dictate safety performance metrics under extreme high-pressure cycling and mechanical vibration.
Prototypes are typically completed in 5 to 7 working days. Mass production batches generally take 15 to 25 days, depending on geometry complexity, tooling preparation, and required surface treatments. We offer international sea, air, and express delivery to keep your supply chain running smoothly.
