What is Investment Casting?

Investment Casting, known as Lost Wax Casting. It is a manufacturing process that use to create complex metal components with high-precision and with great surface finish. “Investment” comes from the old sense of invest, which first meant to cover or surround something with layer of material. It is a common choice for tight tolerances, intricate geometrics and minor secondary processing.

This process is widely applied in applications like aerospace, automobile, oil & gas, pumps, food and dairy processing, general engineering etc. as it produces robust and corrosion-resistant components, having high-strength.

Are various types of materials used in investment casting?

Investment casting can be used on many types of metals and metal alloy, such as stainless steel, alloy steel, super alloy, aluminum, brass and bronze. Type of material selected is a function of service power, corrosion and heat resistance needs.

Lightweight and quality components with superb repeatability, provided by investment casting, that means it is the most dependable method for both, commercial & industrial use.

Investment Casting Complete Process

1. Tool and Die Making

  • Hardened steel or aluminium dies are used to bulk waxy patterns.
  • CAD/CAM and CNC processing are used to achieve complex geometries and close tolerances.
  • The surface finish of castings accuracy depends on the quality of the tooling.

2. Wax Injection

  • Petrochemicals (eg, waxes and thermoplastic materials) are molten and pressure-moulded in precision dies.
  • The wax solidifies when cooled, leaving behind an image of the final part.
  • Dimensional tolerances are inculcated in the die to offset the metal contraction on solidification.

1. Tool and Die Making

  • Wax patterns are attached to a central sprue to create a “tree” needed to cast multiple parts at once.
  • Precision handling results in precise alignment and minimizes the appearance of defects in the casting.
  • Wax gates and runners are designed for efficient metal flow.

4. Coating (Shell Building)

  • The wax assembly is then dipped in refractory ceramic slurry and stuccoed with fine sand.
  • Multiple coats are interspersed with drying, to form a shell that is 5-10 mm thick.
  • The mould must be able to withstand high pouring temperatures and rigidity must be retained.

5. De-Waxing

  • The ceramic-coated assembly is put in an autoclave (steam chamber) or a furnace to heat until the wax melts and runs out.
  • The dewaxing process leaves a cavity inside the ceramic shell that is a copy of the part shape.
  • This step ensures there will be no adhesion problems resulting from leftover wax or dampness.

6. Melting (Metal Pouring)

  • Inductive or vacuum melting of stainless steel, aluminium, or super alloys
  • The preheated ceramic mold is filled with molten metal by gravity, vacuum or centrifugal pressure.
  • Regulated pouring allows full filling of the mold with reduced porosity or inclusion Heat Treatment.

7. Heat treatment of castings

  • This is performed to improve the mechanical properties e.g. tensile strength, increase in hardness & ductility.
  • Processes range from anneal to normalized or solution treatment for alloys and applications.

8. Casting Inspection

  • Detection of defects by NDT such as X-ray, ultrasonic or dye penetrant inspection.
  • CMMs confirm dimension tolerances to production print.

Visual control provides a good surface finish and removes remnants of ceramic material.

Technology and Innovations

In the modern day industry and manufacturing, the application of technology and inventions is critical within the business structure. In the case of our business, we have constantly tried to improve our casting processes in the facility, using technology capable of catering to the improved requests of the refinements in precision, strength and efficiencies.

Take for instance a client in the aerospace industry who is looking for complex geometry turbine blades with zero error tolerances. There is a difference between traditional frameworks and the quality needed – the surface and consistency of the blades. This is where we bring a unique touch.

3D Wax Printing & Rapid Prototyping

Time that would have gone to tooling is completely eliminated as we are able to meet the deadline by using sophisticated 3D printers that allow for the construction of wax patterns within a matter of days. Also, waiting weeks will now become a thing of the past.

Automated Shell Building

With our proprietary technology, we are now able to coat the ceramic shells of the blades with a uniform coated thickness, with minimized shedding as a by-product. We have, as a result of these advancements, improved the reliability and durability of that mold the components, as verified by thorough testing.

Advanced Simulation Software

Before a metal is poured on the mold, our casting simulating tools allow for the prediction of how a molten metal would flow and solidify. This, saves time and costs by eliminating the chances of porosity and shrinkage, which are classified as defects.

Proper Melting & Pouring Solutions

With induction furnaces that utilize controlled atmospheres, we can produce melts that are clean and contain minimal inclusions. This is critical for environments like medical implants and defenses.

Elevated Quality and Slash Costs

Each component goes through Non-Destructive Testing (NDT), Electronic Dimensioning and metallic testing to ensure it meets accepted standards. That’s why we can give you guarantees of safety, reliability and global compliance.

Consequently, investment casting has gone from a hands-on traditional way of manufacturing to an advanced technology based solution for modern industries. Whether it is a component from an automotive engine, a surgical device, or an aerospace component, we promise that each and every casting meets the highest standards of accuracy and efficiency.
