Prototypes are required for product testing and 3D printed parts may not be adequate. In some requirements, prototypes must be made from the production material, in this case glass filled nylon. Part geometry must be the same as the final production parts so that the test results are valid. Actual production material for prototype testing is needed before commitment to high volume injection molds.
The customer chose to solve their problem using PMT injection molding. We made the tools from P20 tool steel and the cavities were produced using EDM. All the details and features were not possible with machining alone.
The parts were delivered in 4 weeks and allowed full product testing, resulting in confidence that the production parts would perform the same.
