Automotive Investment Casting & Precision Machining
Components for the automotive industry require exceptional durability, high performance, and precise dimensional accuracy to withstand extreme operating conditions.
At Vastcast, we manufacture and supply investment castings and precision-machined parts for a wide range of automotive applications, including engine systems, chassis structures, heat management solutions, and drivetrain components.
These parts are widely used in turbochargers, manifolds, suspension systems, transmission housings, and other critical automotive assemblies.
We have established long-term partnerships with automotive manufacturers and Tier 1 suppliers. With our one-stop production capability, we deliver high-quality castings and precision components with fast turnaround times.
We process materials such as stainless steel, aluminum alloys, heat-resistant steels, and titanium alloys. Sizes range from small precision parts to large structural castings, with weights from a few grams to over 80 kg.
Automotive components demand superior strength, heat resistance, wear resistance, and lightweight performance. For example, turbocharger housings and exhaust manifolds are cast with high-temperature alloys, while structural parts leverage aluminum alloys to reduce vehicle weight and improve fuel efficiency.
