    Metal forming is a complex process that can include a number of tactics — blanking, punching, bending, and piercing, to name a few.
    When used effectively, these tactics allow manufacturers to produce high-quality and cost-effective metal components. However, a few factors play into this quality and efficiency, and each project varies in materials, design and complexity:
        – How do you know whether your part’s design will work for the intended application?
        – Will your material of choice withstand all the elements it needs to function?
    XingHui brought in our Engineering Manager, to answer some of the most frequently asked questions we receive about the metal stamping process.
     Q: How do I keep costs low for a metal stamping project?
    A: Optimizing the cost of your metal stamping project: careful consideration of three main factors: material selection, dimensional tolerances, and secondary or post-production processes.
    Appropriate material selection is usually the first and most effective step to lowering costs. For a given application, consider whether an alternative metal with similar properties can be used. For example, when creating components for use in corrosive environments, another, more cost-effective Metal with similar corrosion resistance could be considered.
    Achieving tight tolerances during manufacturing can be complex due to the sensitivity of the component’s dimensions. Tight tolerances often require additional tooling maintenance and downtime which adds to the Metal Stamping Parts cost. Revaluate your project and determine whether the tolerances need to be as tight as specified.
        Secondary Processes
    Post-production processes - such as smoothing the edges of the stamped part - can also incur additional project costs. Vibratory deburring and edge grinding usually involved complex machinery and can be potentially expensive depending on the size of the component and its production volume. Evaluate whether Less costly methods of edge smoothing, such as coining, can be used for your metal stamped part.
