Step 3:
​A comprehensive material analysis is performed on the sample parts to determine the exact matrix material as well as any additives, or fillers, within the matrix. This step is critical as even a slight variation in the filler can drastically change the performance of the part.

Step 6:
​ESP machines sample parts in a first run. These parts are carefully inspected by our quality control team to ensure all aspects of the part meet the specifications. Samples are generally provided to the customer for qualification.

Step 2:
​ESP captures all of the dimensions, tolerances, and surface profiles of the sample parts. We utilize different metrology equipment including CMMs, optical comparitors, and profilometers, to capture this information.

Step 5:
(Optional) At the customer’s request, ESP can change almost any characteristic in the design to improve the part’s performance. These changes are easily implemented into the process, providing a quick and simple way for customers to test new designs.

​​​​Reverse engineering (RE) spare parts and consumables is one of ESP's core competencies. Every part is subjected to our thorough RE process to ensure every detail is captured. Our facility, equipment, and manufacturing expertise allow us to offer spare parts at a fraction of the cost without sacrificing quality or performance. ESP has saved our customers hundreds of thousands of dollars annually by supplying their spare parts.

Step 1:  
ESP begins with a detailed review of the project with the customer. We discuss the part’s critical features, mating parts, the operating environment, and so forth to gain a complete understanding of the project. We will collect a samples at this time.
