Ceramic-coated heat-resistant manifold castings
Super Quali Cast’s investment castings for exhaust manifolds are IATF 16949-compliant ICE components that withstand demanding workloads. Exhaust manifolds are routinely exposed to working temperatures of 600°C and beyond. Heat-induced stress leads to cracks, leaks, and failures in automotive exhaust manifold castings. Lost-wax casting, with its precision output, uniform grain distribution, and tight tolerances, produces exhaust manifold castings that meet these challenges.
We produce log-style, collector-style, and turbo manifold castings in our state-of-the-art foundry. We also pour exotic alloys and produce custom designs that meet proprietary standards. Our castings for exhaust manifolds are supplied to OEMs and Tier-1 automotive manufacturers in all leading countries.
Our Manufacturing Process for Exhaust Manifold Castings
Our investment casting for exhaust manifold production includes multiple steps, each designed to provide incremental improvements to the final product.
- High-Precision Molding: Creates accurate product impressions and negative cavities.
- Gravity Pouring: Ensures an even spread and precise geometry during formation.
- Heat Treatment: Enhances tensile strength, surface hardness, and grain distribution.
- CNC Machining: Establishes tight tolerances, geometric accuracy, and superior surface finish for precision investment casting components.
- Final Inspection: A range of visual, material, and dimensional tests for error-free output.

FAQs
Is there support for rapid prototyping for exhaust manifold castings?
Yes, we support rapid prototyping for exhaust manifold castings, which allows us to compress your tooling timelines.
Can investment casting tackle complex internal geometries?
Yes, investment casting can tackle the complex internal geometries that are routine for exhaust manifolds. Traditional forging methods may struggle to produce curves and bends that meet exacting tolerances.
Which materials are best suited for investment castings for exhaust manifolds?
Cast iron investment castings are cheaper compared to the alternatives, but stainless steel and superalloys are preferred where high performance is the goal.
What internal checks and tests do you run for castings for exhaust manifolds?
We run a suite of non-destructive tests, such as X-ray and dye-penetrant, to rule out porosity and hairline cracks. We also run material tests before pouring to minimize defects in the output.
Will these castings require heavy CNC operation?
Investment casting produces near-net shapes with excellent surface finish. This reduces the need for heavy CNC operations. However, some degree of machining is required to establish tight tolerances and perfect seals.
