Question 1

Why is it important for the manufacturer to know whether a sheet metal part is external or internal?

Accepted Answer

Knowing whether a part is external or internal is crucial because it directly impacts how the manufacturer decides to produce it. External parts require a Class A finish with no imperfections, which affects the manufacturing process and costs. Internal parts, on the other hand, don't require cosmetic finishing, allowing for cost savings.

Question 2

What is the significance of designating a part as a "show part"?

Accepted Answer

Show parts are external components that must have a flawless, Class A finish. They demand extra attention to detail, including polishing, and may involve additional finishing techniques. Communicating that a part is a show part to the manufacturer ensures accurate quoting and meeting deadlines.

Question 3

How does informing the manufacturer that a part is for internal use impact the quoting process?

Accepted Answer

If a part is designated for internal use, the manufacturer can adjust the quoting accordingly, eliminating costs associated with cosmetic finishing. This adjustment doesn't affect the part's quality, strength, or tolerances; it only relates to its cosmetic appearance.

Question 4

Can designating a part as internal result in cost and time savings?

Accepted Answer

Yes, designating a part as internal can lead to cost and time savings. By not requiring cosmetic finishing, such as finish grinding, the manufacturing process becomes more efficient, reducing both the cost and lead time for the part.

Question 5

What should I do if my current manufacturer doesn't ask about the intended use of my part?

Accepted Answer

If your current manufacturer doesn't inquire about the intended use of your part, consider discussing your requirements with Approved Sheet Metal. They proactively inquire about the part's purpose and recommend finishing options to achieve the desired appearance while optimizing cost and time savings.
