Throttle Valve Assembly
The process begins with a part number or new or used sample for your made to order parts.
After receiving your sample, we confirm all required properties using our state of the art equipment; properties such as dimensions, hardness, and material composition. In addition we will consider all application parameters as well.
We utilize state-of-the-art 3-D laser scanning technology to reverse engineer the parts to achieve the original design intended.
We employ GOM 3-D structured light scanner, material analyzer and a 3-D printer.
