In the evolving landscape of high-performance transportation, the turbocharger remains the heart of heavy-duty truck efficiency. As global emission standards (Euro VI, EPA 2027) tighten, the demand for custom high performance truck turbocharger castings has shifted from basic structural components to advanced thermal management solutions. These castings must withstand extreme temperatures exceeding 1000°C while maintaining dimensional stability under high pressure.
Our manufacturing process leverages Lost Wax Investment Casting to produce complex turbine housings and compressor covers that provide higher aerodynamic efficiency and lower fuel consumption for modern fleet operations.
Founded in 2014, located in Weifang, Shandong, we occupy 60,000 m² with an annual capacity of 20,000 tons. We are an E-E-A-T verified leader in high-tech precision castings.
Our facility is equipped with internationally advanced automated casting lines. This ensures consistency in wall thickness—a critical factor for high-performance turbochargers where weight reduction meets high pressure.
We specialize in Ni-Resist alloys, stainless steel, and heat-resistant alloy steel. Our physical and chemical analysis equipment ensures the mechanical properties of every batch meet strict automotive standards.
Not just a foundry, but a finished component provider. Our CNC machining centers (horizontal & vertical) provide tolerances as tight as ±0.01mm for critical mating surfaces of turbocharger housings.
Located in the industrial heart of Shandong, we have direct access to high-grade raw materials and logistics, reducing lead times for global shipping.
Leveraging advanced automation and skilled engineering, we provide Tier-1 quality at competitive pricing, maximizing ROI for truck OEMs.
Our engineering team can transition from CAD design to physical casting prototypes in record time, accelerating your time-to-market for new engine models.
We implement sustainable casting practices and energy-efficient furnaces, meeting the green manufacturing requirements of global enterprises.
Evolution of the Trucking Industry: The industry is moving toward Variable Geometry Turbocharging (VGT) and twin-scroll designs. These require increasingly complex interior geometries that only precision investment casting can achieve without excessive secondary machining.
Providing high-fatigue resistance turbine housings for long-haul freight vehicles operating under constant high-load conditions.
Corrosion-resistant stainless steel castings for maritime turbochargers, ensuring longevity in salt-spray environments.
Custom castings for range-extender engines in electric-heavy trucks, focusing on ultra-lightweight designs.
Every casting undergoes rigorous testing: X-ray flaw detection, Magnetic Particle Inspection (MPI), and CMM dimensional checking. Our certifications include:
