Product Description
Revolutionizing Automotive Performance with Additive Manufacturing
Our Inconel 718 turbocharger housings represent a breakthrough in automotive component manufacturing, combining the design freedom of laser powder bed fusion (LPBF) with the precision of multi-axis CNC machining. This hybrid approach delivers superior performance characteristics that traditional sand casting cannot match.

Frequently Asked Questions
Q: What materials are available for turbocharger housings?
We offer Stainless Steel grades including SUS316L, SUS304L, CX, and 18Ni300, alongside superalloys such as Inconel 718.
Q: How does LPBF combined with 5-axis CNC machining improve component performance?
LPBF allows the integration of complex internal cooling channels and achieves a 25% weight reduction over sand casting, while 5-axis CNC post-machining delivers positional accuracy within 0.001mm and runouts under 0.03mm on critical flange surfaces.
Q: What surface roughness and dimensional tolerances can be achieved?
Critical features achieve dimensional tolerances of ±0.05mm. The as-printed surface finish is Ra 6–8μm, and the post-machined surface achieves Ra 0.4–0.8μm (Ra <0.8μm on combustion faces).
Q: How much production time is saved compared to conventional billet machining?
Near-net-shape 3D printing cuts CNC machining time by 60% to 80%. For instance, Inconel 718 turbine blades require only 2 hours of 5-axis machining compared to over 12 hours for full billet machining.
Q: What quality inspection standards are implemented during production?
Quality assurance includes 100% CMM dimensional inspection, surface roughness checks, non-destructive testing (FPI/RT), and raw material certification according to AMS 5662/5663 standards.
Q: What sectors are these turbocharger housings engineered for?
Primary applications include high-performance automotive turbochargers, motorsport vehicles, heavy-duty diesel engines, and marine turbocharging systems operating up to continuous temperatures of 700°C.
