Q: What are some DOs and DON'Ts when working with a precision sheet metal shop?

DO : Keep parts uniform in thickness for consistency. DO : Include necessary hardware in your design. DO : Provide appropriate gaps (e.g., .005 to .0015) for connecting parts. DON'T : Spend excessive time unfolding parts; consider splitting complex parts. DON'T : Cut or tab corners in a way that could compromise manufacturing. DON'T : Start with a solid shell; it's more efficient to begin with an assembly. Remember, if your manufacturer isn't guiding you through the design process, our experts are here to help.

Question 1

Why is Design for Manufacturability (DFM) important in sheet metal manufacturing?

Accepted Answer

DFM ensures that a part is optimized for production by considering factors like material formability, machine capabilities, lead time, and cost. It prevents issues like change orders and reworks, leading to higher quality parts.

Question 2

How can involving a precision sheet metal shop early benefit part design?

Accepted Answer

Precision sheet metal shops possess expertise in machine operations and materials. Involving them early allows them to provide insights and make informed decisions about aspects like material selection, tolerances, and approach, which can improve the overall outcome.

Question 3

What problems can arise when welding sheet metal parts?

Accepted Answer

Welding can lead to issues such as material shrinkage, complex fixture requirements, inspection challenges, backwards assembly, parts out of tolerance, corner gaps, and even cracking. These problems can drive up costs and lead times.

Question 4

How can interlocking tabs help solve welding-related issues?

Accepted Answer

Interlocking tabs can hold parts in place, enhance strength, and mitigate welding complications. They address problems like material shrinkage, gaps, and assembly misalignment, improving the overall welding process.
