Industry-leading aftermarket solutions for heavy-duty trucking and machinery.
In the evolving landscape of global logistics, the demand for high-reliability aftermarket truck parts has shifted from mere cost-saving to a strategic performance necessity. As a leading manufacturer based in Weifang, Shandong, JUNLONG Machinery Co., Ltd. represents the pinnacle of this transition. Founded in 2014, we have bridged the gap between OEM quality and aftermarket accessibility.
The core of our advantage lies in Information Gain: providing clients with not just products, but data-driven manufacturing insights. Our 60,000 square meter facility isn't just a factory; it's a hub of 20,000-ton annual capacity where carbon steel, alloy steel, and stainless steel are transformed into mission-critical components for the world's leading truck fleets.
E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness in every cast.
Equipped with internationally advanced automated production facilities and comprehensive physical/chemical analysis labs. We enhance manufacturing efficiency and product stability, meeting rigorous mechanical property tests for diverse alloys.
Leveraging strong engineering and a complete QC system, JUNLONG has become a well-known brand exported to Germany, USA, Italy, and Canada. We serve global industry leaders with mid-to-high-end solutions.
We are a key supplier for automotive, rail, engineering machinery, and petroleum sectors. Our lost-wax investment casting technology ensures high dimensional accuracy and complex geometric capabilities.
For global enterprises, "compliance" is the non-negotiable bedrock of procurement. JUNLONG Machinery adheres to the highest international standards, ensuring that every aftermarket truck part is a seamless fit for local regulations in Europe, North America, and beyond.
Verifiable quality through international certification bodies.
The aftermarket truck parts industry is moving toward "Predictive Maintenance" components. Suppliers who can offer sensors-ready castings and lighter, high-strength alloys are winning the market. China’s supply chain has evolved from "labor-intensive" to "intelligence-intensive," utilizing AI-driven simulation for casting flow and thermal stress analysis.
Our "Full Industrial Chain Integrated Manufacturing" reduces lead times by 30%. From mold manufacturing to machining (CNC lathes, vertical machining centers) and surface treatment, everything is under one roof. This minimizes the "Quality Gap" often found in fragmented supply chains.
Investing in the future of precision machinery.
Precision castings for diverse extreme environments.
Custom lost wax components for harvesters and farm vehicles designed for high-wear resistance in soil-contact applications.
High-precision cable protectors and valve accessories for deep-sea and land-based oil drilling operations.
Heavy-duty structural components for excavators and cranes, engineered to withstand extreme mechanical loads.
Chassis components, engine brackets, and drivetrain parts that meet or exceed OEM performance metrics.
Investment steel castings for high-speed rail systems, focusing on vibration dampening and structural integrity.
Corrosion-resistant stainless steel castings for maritime hardware and propulsion systems.
Expert answers for procurement professionals.
We specialize in carbon steel (like Q235), various alloy steels, and high-grade stainless steel. Our precision casting process allows us to manipulate material properties to match the specific stress requirements of heavy-duty trucks.
Quality is maintained through our IATF 16949 system. We perform spectral analysis for chemical composition, ultrasonic testing for internal defects, and CMM dimensional inspections to ensure 100% geometric compliance.
For new mold development, it typically takes 3-4 weeks. Production lead times range from 4-6 weeks depending on the complexity and volume, thanks to our 20,000-ton annual capacity.
Yes, we offer a full suite of surface treatments including zinc plating, powder coating, painting, and specialized anti-corrosion treatments for petroleum and marine applications.
