In the high-stakes world of commercial logistics, the reliability of a truck's braking system is non-negotiable. As a premier OEM precision cast truck brake system parts manufacturer, JUNLONG Machinery Co., Ltd. (founded 2014) leverages a decade of metallurgical expertise to produce safety-critical components that withstand extreme thermal stress and mechanical fatigue. Our 60,000 square meter facility in Weifang, Shandong, serves as a global hub for investment casting excellence, integrating advanced material science with precision machining to deliver parts that exceed international safety standards like IATF 16949.
From brake calipers and spiders to slack adjuster housings and air brake valves, our components are engineered for "Zero Failure" performance. We provide an Information Gain advantage to our partners by not just manufacturing parts, but by optimizing the entire supply chain—reducing weight without sacrificing strength and ensuring localized compliance across North America, Europe, and Asia.

Utilizing state-of-the-art lost-wax technology, we achieve near-net shapes with tolerances as tight as CT4-CT6. Our automated production line ensures metallurgical consistency across high-volume runs, critical for brake system integrity.
We specialize in 16Mn, stainless steel (304/316), and high-strength alloy steels. Our internal lab performs comprehensive spectral analysis and mechanical testing to ensure every batch of brake parts handles the heat of heavy friction.
From mold design and casting to CNC machining and surface coating (EDP/Dacromet), we control the entire lifecycle. This eliminates secondary vendor risks and shortens lead times by 30% compared to fragmented suppliers.
Navigating global regulatory landscapes is a core competency. Our truck brake system parts are manufactured to meet DOT (Department of Transportation) and ECE R90 standards. We provide full Material Test Reports (MTRs) and Certificate of Conformance (CoC) documents with every shipment. For global enterprises, we offer localized warehousing support and JIT (Just-In-Time) delivery capabilities through our logistics partners in the US, Germany, and Canada.
Located in Weifang, the "Power City" of China, JUNLONG Machinery benefits from a world-class manufacturing ecosystem. This allows us to source high-grade raw materials at competitive rates and access a highly skilled labor force. The synergy between local heat treatment specialists and surface finishing plants allows us to offer premium OEM precision cast parts at a cost structure that is 20-40% more efficient than Western counterparts without compromising E-E-A-T principles.
Modern procurement directors demand more than just low prices; they demand risk mitigation. JUNLONG’s ISO 9001 and TS 16949 certifications provide the baseline for reliability. We utilize AI-driven production scheduling and ERP systems to provide real-time status updates, ensuring that your assembly lines never stop. Whether it's custom stainless steel components or high-manganese steel heavy-duty parts, our capacity of 20,000 tons per year handles the largest global orders.
As the industry shifts to EV trucks, reducing unsprung weight in the brake system is critical for battery range. We are developing thin-walled high-strength alloy castings that offer 15% weight reduction while maintaining safety margins.
Integration of sensors into casting designs. We are pioneering brake housings with pre-cast sensor ports for real-time wear monitoring and autonomous emergency braking (AEB) compatibility.
Parts designed for the Canadian Arctic or Middle Eastern deserts. Our specialized heat treatment processes ensure that brake components retain ductility at -40°C and resist oxidation at 600°C.
JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the company covers a total area of 60,000 square meters and has an annual production capacity of 20,000 tons of precision castings and machined finished parts. It specializes in materials such as carbon steel, alloy steel, and stainless steel.
With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing. Our facilities include horizontal and vertical machining centers, CNC lathes, and comprehensive physical/chemical analysis equipment.
Furthermore, the company has obtained ISO 9001, TS 16949, UL, and other quality management system certifications, ensuring process control over every production detail and continuously pursuing high customer satisfaction.
Investment casting (lost wax) provides superior surface finish and dimensional accuracy. This reduces the need for extensive machining, ensures better heat dissipation across the part, and eliminates common sand casting defects like porosity, which are dangerous for pressure-bearing brake components.
We recommend 16Mn or specialized Alloy Steels (like 4140) for high-load applications. For corrosive environments (coastal logistics), our Stainless Steel (304/316) precision castings offer the best longevity and resistance to salt-induced failure.
Yes. Our engineering team uses simulation software to analyze fluid flow and solidification during the casting process. We help clients optimize wall thickness and geometry to improve strength while reducing material cost.
Every production run undergoes strict APQP and PPAP (Production Part Approval Process). We provide full traceability from the raw material melt to the final machined surface, ensuring compliance with global automotive standards.
