The global heavy-duty truck market is undergoing a seismic shift. As logistics networks expand and environmental regulations tighten, the demand for Investment Casting (Lost Wax Casting) components has skyrocketed. Unlike traditional sand casting, investment casting provides the dimensional accuracy and surface finish required for modern high-efficiency engines and lightweight chassis structures.
Currently, the market is characterized by a transition toward Euro VI and EPA standards, which require engine components to withstand higher pressures and temperatures. From Germany to the United States, fleet operators are seeking "Information Gain" in their supply chain—not just parts, but engineering solutions that reduce fuel consumption and extend vehicle uptime. Investment casting, particularly in alloy steel and stainless steel, offers the perfect balance of strength-to-weight ratio needed for this evolution.
Components designed for 1 million+ miles of service life in extreme transcontinental environments.
Reducing unsprung weight through complex thin-wall geometries impossible with sand casting.
Near-net-shape manufacturing reducing secondary machining costs by up to 40%.

The "China Advantage" in truck spare parts isn't just about labor cost—it's about Industrial Cluster Intelligence. In hubs like Shandong, the proximity of raw material suppliers, mold makers, and logistics experts creates a compressed supply chain. At JUNLONG, we leverage Automated Precision Casting lines that ensure consistency that manual foundries cannot match.
Internationally advanced automated production facilities significantly enhance manufacturing stability and reduce human error.
Comprehensive physical and chemical analysis equipment for verifying mechanical properties of every batch.
Streamlined logistics to Germany, USA, Italy, and Canada, ensuring your production line never stops.
Our parts are engineered for performance in the world's most demanding environments.
Forging strong mechanical backbones for excavators and loaders. Our wear-resistant castings support heavy-duty operations in mining and road construction.
High-alloy steel cable protectors and petroleum parts precision cast to withstand corrosive oilfield conditions and high-pressure drilling.
Critical components for cooling systems and transmissions. We provide the precision required for the next generation of logistics vehicles.
JUNLONG Machinery is not just a factory; we are a certified partner. We hold ISO 9001, IATF 16949 (TS 16949), and UL certifications. This ensures that every truck spare part—whether it's a bracket, a housing, or a complex valve—meets the rigorous safety standards of the global automotive industry.
Looking toward 2030, the truck spare parts industry is moving toward Green Casting and Digital Twin integration. As a forward-thinking manufacturer, JUNLONG is investing in:
We work with carbon steel (WCB, LCC), alloy steel (4140, 8630), and stainless steel (304, 316, 17-4PH) to meet various strength and corrosion requirements.
Typically, mold manufacturing takes 3-4 weeks, and production takes 4-6 weeks depending on the complexity and volume of the order.
Yes, we offer shot blasting, galvanizing, powder coating, and heat treatments (quenching and tempering) in-house.
Our investment casting process maintains tight tolerances according to ISO 8062-3 DCTG4-6, verified by our CMM (Coordinate Measuring Machine).
