Reverse engineering: beyond a simple copy, an intelligent reinvention

When do industries need reverse engineering and manufacturing rare industrial parts?

Obsolete Parts: The original manufacturer has stopped producing a machine or machine and no longer supplies spare parts.
Excessive import costs: The price of the original part along with shipping, customs, and middlemen costs makes it uneconomical to procure it. It lasts for months, while your production line is at a standstill.
Lack of access to technical drawing: Design and manufacturing drawings of the part are not available and only one (often worn) physical sample is available.
Need for improvement and upgrading: The original part has a design weakness and fails frequently. You are looking for an improved version with a longer lifespan.
Sanctions and trade restrictions: Access to global markets and major manufacturers is blocked due to political issues and sanctions.

Step-by-step process of reverse engineering at Rasta Precision Casting Company

First step: initial analysis, technical advice and sample review

It all starts with a call and a free technical consultation. In the initial meeting, our experts will check your defective or worn part sample. The performance of the component, its working conditions (temperature, pressure, corrosive environment), and its failure history are carefully analyzed. This step is crucial for fully understanding the "why" of designing the part.

Second step: detailed dimensional analysis with 3D scanning

The physical pattern, however worn, is a treasure trove of geometric information. Using advanced 3D laser scanners, we remove millions of points on the surface of the part with micron accuracy. The result of this process is creating a point cloud file and finally a perfect "digital twin" of your piece. Even if a part of the part is broken or lost, our engineers are able to digitally reconstruct that part according to the symmetry and logic of the design.

The third step: metallurgical analysis to decipher the alloy

"What is this piece made of?" This is a key question, the answer to which will determine the success or failure of the project. The equipped metallurgical laboratory of Rasta Company determines the precise chemical composition of the alloy with an accuracy of 100% using a quantometer (spectroscopic analysis). Then, with hardness and metallographic tests, we decipher the microscopic structure and the type of heat treatment performed on the main piece. This information is necessary to ensure the same or better mechanical properties in the final part.

Fourth step: CAD modeling, simulation and optimization

The data obtained from 3D scanning and metallurgical analysis are converted into a complete and manufacturable 3D model in advanced engineering software (CAD). But our work does not end here. If necessary, using simulation software (CAE), we analyze the model under actual loadings and working conditions to identify potential stress points and weaknesses and optimize the design before construction. This step distinguishes a professional reverse engineering from a simple copy.

Step 5: Select the production method: precision casting power for complex parts

After the finalization of the model, it is time to build. With its unique expertise in the investment casting process, Rasta Precision Casting Company offers the best method for producing many rare industrial parts. Parts such as pump impellers, diffusers, valve internals, and turbine blades that have complex and curved geometries cannot be produced by any better method than precision casting. This process enables the production of parts with excellent surface quality and very tight dimensional tolerances, minimizing the need for expensive and time-consuming machining. This expertise in production is the final link in the successful chain of reverse engineering and manufacturing rare industrial parts.

Sixth step: final production, strict quality control and performance guarantee

After casting, the parts are subjected to the necessary heat treatment to achieve the desired mechanical properties. Then our quality control team steps in. Dimensional inspections, non-destructive testing (NDT) such as liquid penetrant testing (PT) to check for surface cracks and radiography (RT) to ensure the internal health of the part are all done to ensure final quality. We deliver a piece that is guaranteed not only in terms of looks but also in terms of performance.
