Sample Guideline

Guidelines for Sample Checklist

1. 气泡图 [Bubble Drawing]

• Make a clear copy of the drawing and mark each inspection item clearly with numbered stamps (bubbles).
• Ensure all dimensional items, material specifications, additional drawing requirements, and weight are distinctly marked.

2. 检验报告 [Inspection Report]

• Clearly include the following information:
  • Purchase Order (PO) Number
  • Part Name
  • Drawing Number
  • Weight of the part (weigh actual sample)
  • Number each sample clearly to align with recorded inspection data.
• Evaluate each inspection item clearly using "i.O." (OK) or "n.i.O." (Not OK).
• For multi-cavity molds, inspect and record data separately for each cavity.

3. 材料报告 [Material Report]

For Steel/Aluminum:

• Provide a clearly readable scanned Raw Material Certificate.
• Certificate must have the supplier's quality inspection stamp and PO number clearly marked.
• Confirm specific requirements from the drawing such as heat treatment or surface finish.
• Conduct hardness testing at an appropriate location on the actual component to verify material identity.

For Plastics:

• Include a clearly readable Raw Material Certificate.

4. 样品 [Samples]

• Attach the measured samples directly to the initial sample inspection report.
• Clearly label each sample with numbers that exactly match the numbers in the inspection report.
• Ensure sample identification is accurate, consistent, and traceable to the inspection documentation.
