Rapid Prototype for Investment Castings

investment casting

Investment casting is a complicated metal forming method that normally requires producing a mould with a wax pattern enclosed by a ceramic shell. When the shell has dried, the wax is removed and a ceramic mould is created. 

Investment casting foundry may also be a handy choice for prototyping throughout the design phase. By constructing a tangible representation based on the original drawings and plans, rapid prototyping may assist designers and engineers in quickly receiving input on the feasibility of a new component. 

What is Investment Casting Rapid Prototyping?

Prototyping is one of the first steps in demonstrating a design concept before going into full manufacturing. It aids in the detection of possible issues and allows process engineers to make appropriate modifications. Rapid prototyping is a short design method that entails developing a concept, immediately producing a prototype, and testing that physical item or model.

For prototype, a hard-tooled wax pattern can be utilized, but most modern foundries use printed 3D wax technology as a cost-effective and efficient alternative for quick prototyping and limited production runs. 3D printing may be utilized to create complicated investment castings that require design changes or are on a tight timeline.

What is the Rapid Prototype Process for Investment Castings?

In general, the following phases are included in the quick prototype for investment casting process:

CAD Modeling: A three-dimensional picture of the intended prototype is created using advanced software.

Conversion: To investigate the layers of the proposed design, the CAD model is translated into a format that allows for virtual slicing.

Slicing: The digital file is really sliced to generate cross-sectional outlines for the model.

Fabrication of the Model: An initial prototype is printed by stacking the produced layers on top of each other.

Post-Processing: The layering process produces a physical wax design, which is subsequently cleaned and completed before moving on to the following stages of the investment casting foundry process.

What Are the Advantages of Investment Casting Rapid Prototyping?

Rapid prototyping for investment castings offers several advantages:

  • Product development now has a shorter lead time.
  • When the prototype design is complete, it may be directly included into a full production run.
  • This is a highly flexible technology for product development scenarios when design changes are required, or when the project has a limited development time window.
  • Ideal for the creation of intricate pieces.

However, the most significant advantage of fast prototyping for investment castings is that it enables for rigorous testing of a product early in the design phase.

Reduce Lead Time and Costs Making Use of Rapid Prototype Investment Casting

Engineered Precision Casting Company can provide aerospace quality quick prototype castings in as little as 5 weeks from a CAD file. We’ve made hundreds of prototype castings in a wide range of designs, from one-piece oil and gas prototypes to production runs on aerospace parts.

Engineered Precision Casting Company produces all quick prototype castings using the same casting materials as our investment castings. We have expertise generating quick prototypes utilising a number of 3-D printed materials, allowing us to provide cost and quality choices for your project.

We employ the following methods to create quick prototype castings:

  • Polystyrene in Cast Form (PS)
  • Apparatus for Stereo lithography (SLA)

Conclusion

Rapid prototyping in investment casting foundry is a proven way to swiftly generate metal castings during the basic design phases of an investment casting project. This allows you to run a sample design, which can help you avoid costly tooling adjustments. Rapid prototype castings are frequently less expensive and time-consuming than the processes of machining prototypes from bar stock or creating prototypes using weldments.
