Investment Castings for Compressor Wheels

Compressor Wheels

High-performance compressor

Super Quali Cast’s investment castings for compressor wheels minimize rejection rates and improve production consistency for Tier-1 manufacturers and OEMs. Compressor wheels are intricate by design, and even minor dimensional deviation can affect performance and efficiency. The investment casting process produces a near-net finish that meets design and performance standards. Design compliance, tight tolerances, and geometric accuracy are the norm.

We have supplied high-precision compressor wheel castings to power plant engine and turbine manufacturers globally for nearly a decade. Learn how we can apply our production capabilities to your project.

Our Compressor Wheel Castings Manufacturing Process

Compressor wheels are complex assemblies. The nose, hub, blade root, exducer, splitter blades, back disc, main blades, inducer, and balance cuts come together to form the wheel.

Here’s how we produce them

  • High-Precision Molding: 1:1 wax models for accurate geometry.
  • Investing: Coating the wax model in ceramic to form a robust shell.
  • Gravity Pouring: Pouring molten alloy into the ceramic cavity to form the compressor wheel.
  • Heat Treatment: Improving surface hardness and grain redistribution
  • CNC Machining: Making precise adjustments and finishes to ensure superior fit and finish.
  • Final Inspection: Visual, material, and physical checks to ensure zero-error output.

Frequently Asked Questions

Cast or Billet: Which is better for manufacturing compressor wheels?

Cast compressor wheels are preferred for high-volume, cost-effective production. Billet manufacturing is subtractive and preferred for low-volume, high-power applications.

What is the surface roughness of the compressor wheel castings?

Surface roughness for compressor wheel castings is in the range of Ra 1.6 µm.

Do you provide rapid prototyping?

Yes, we provide rapid prototyping using modern stereo lithography to compress tooling timelines and improve lead times.

Do you have provision for secondary operations?

Yes, we have provision for secondary operations. Our machine shop is equipped with modern VMCs and CMCs to ensure tight tolerances and compliance with international standards.

What is the function of a compressor wheel?

Compressor wheels in a power plant function as a rotating impeller. They draw in, compress, and deliver ambient air to optimize fuel burn and achieve greater power output.
