Custom CNC Parts manufacturing
Prototyping Custom CNC Part


Prototyping is the initial stage in the production of custom CNC parts. This involves creating a single, functional model of the part to test its design and function. At RALLY, we understand the importance of prototyping in eliminating design flaws, verifying design functionality, and saving costs in the long run.

Pre-Production Custom CNC Part


Once the prototype has been tested and approved, we move on to the pre-production stage. Here, we prepare for mass production by setting up our CNC machines according to the design specifications. We also perform a small production run to verify the setup and ensure the process's efficiency and accuracy.

Production Custom CNC Part


In the production stage, we ramp up to full-scale manufacturing. Our state-of-the-art CNC machines are capable of producing high volumes of parts while maintaining consistency and precision. Regardless of the size of your order, we are committed to delivering high-quality custom CNC parts that meet your exact specifications.

Post-Production Custom CNC Part


After the production phase, we perform post-processing operations as needed, such as finishing, painting, or anodizing. This not only enhances the appearance of the custom CNC parts but can also provide additional features like increased corrosion resistance or improved surface hardness.
