Before investing in a new injection mold, decide what the prototype needs to prove.
Is the main question about appearance, fit, assembly, movement or how the product performs in use? The answer helps determine whether a 3D-printed model, CNC-machined part or another development sample is appropriate.
At PlasticNavi, our product design and engineering review considers the part structure alongside the requirements of tooling, molding and assembly. That helps identify changes while they are still easier to make—before committing to a production mold.
