Use this checklist for locks, rings, hooks, chains, buckles, decorative details, eyelets, studs or handle attachments. You do not need every answer before the first conversation, but each missing item should be visible as an open question.
1. Product context
- What finished product will use the component?
- Where will the part sit on the bag, case, accessory or pet product?
- Can you share a product photo, sketch, cross-section or assembly view?
- Which neighbouring materials touch the part?
2. Drawing and dimensions
- Attach the current drawing or a clear reference photo.
- Mark the dimensions that control fit and assembly.
- Include material thickness, webbing width, hole size and clearance where relevant.
- State the drawing revision or date.
3. Function and use
- Does the part lock, twist, clasp, adjust, swivel, attach, protect or decorate?
- What is the direction of pull or movement?
- What should the user feel when opening, closing or adjusting it?
- What repeated-use condition should the sample represent?
4. Material and finish
- Is zinc alloy, copper, iron or stainless steel required or preferred?
- Are you open to a supplier recommendation after drawing review?
- What plating colour or custom colour should be followed?
- Can you provide a physical surface reference?
5. Sampling and tooling
- Do you need a visual prototype, a functional metal sample or both?
- Would 3D printing, CNC work or a zinc-alloy sample answer the first question?
- Does the project require tooling and trial work after sample approval?
- Who approves appearance, fit, function and finish?
6. Quantity and commercial details
- What is the expected order quantity and launch timing?
- What quantity is needed for the first sample review?
- Is the catalogue MOQ from 500 pcs suitable for the program?
- Does the quotation need to separate sample, tooling, finish and production work?
7. Quality requirements
- Which dimensions need to be checked?
- Is pull-force discussion needed for the part or application?
- Should a packed-product vibration check be considered?
- Does opening and closing, spring fatigue or surface testing matter?
- Which test method and acceptance target should be agreed?
Keep the boundary clear: A checklist helps structure the inquiry. It does not replace the project drawing, approved sample or agreed specification.
What to send first
If time is limited, send the drawing or reference, one photo of the finished product, the main function, material and finish direction, estimated quantity and your biggest concern. That is enough to start a focused conversation.
When ready, use the RFQ form. It opens a draft email for your review; it does not save the inquiry on this static website.
