  • What principles should be observed in DFM service analysis?

    What principles should be observed in DFM service analysis?

    1 | Processing The selected manufacturing process must be the correct process for the part or product. You don’t want to use high-capitalization processes (such as injection molding), which involve building tools and molds to make small batches of parts that could have been manufactured usi...
