Zinc Die-Casting Cosmetic Boundary Definition During RFQ
For zinc die-cast appearance parts, RFQ should define what the customer will see, touch, inspect, and reject. XSD Precision treats cosmetic boundary definition as an engineering input, not a late-stage appearance discussion.
Core Position
Cosmetic quality should not be left until after tooling or first samples. The RFQ stage should define visible surfaces, non-visible surfaces, customer-facing edges, assembly contact areas, plating or coating zones, polishing limits, and unacceptable marks. When this boundary is clear, price, process route, inspection method, and sample approval all become more realistic.
What Must Be Defined Before Quotation
Useful inputs include 2D and 3D drawings, sample photos, visible-surface marking, finish target, color or gloss expectation, logo or decorative area, salt-spray target, packaging protection, annual volume, and whether a master sample or limit sample is required. If the customer can mark A/B/C cosmetic zones, XSD can separate critical appearance areas from functional or hidden areas.
Where Cosmetic Risk Usually Enters
Risk often enters through parting line position, gate location, ejector marks, polishing access, local porosity, sharp edges, thin ribs, masking areas, and secondary machining. A surface that looks easy in a drawing may become difficult after deburring, polishing, plating, or assembly. XSD reviews the full route instead of judging the casting alone.
How the Boundary Becomes Inspection Language
The boundary should be converted into inspection distance, lighting condition, viewing angle, defect examples, sample reference, and record format. For appearance parts, words such as scratch, pit, stain, color variation, burn mark, flow mark, and polishing wave should be connected to actual acceptance limits.
Buyer Value
A clear cosmetic boundary reduces repeated quotation, sample disagreement, and mass-production disputes. It also helps procurement compare suppliers by appearance-control method, not only by tooling cost or unit price.

Mark customer-facing and touch surfaces on the drawing Prevents hidden assumptions during sample approval
Clarify plating, coating, polishing, masking, and corrosion target Reduces finish dispute after casting
Define light, distance, angle, sample and defect examples Makes quality judgment repeatable
| Control object | XSD review method | Buyer value |
|---|---|---|
| Visible surface | Mark customer-facing and touch surfaces on the drawing | Prevents hidden assumptions during sample approval |
| Finish route | Clarify plating, coating, polishing, masking, and corrosion target | Reduces finish dispute after casting |
| Inspection method | Define light, distance, angle, sample and defect examples | Makes quality judgment repeatable |
| CTQ link | Connect appearance zones to CTQ or special characteristics where needed | Moves appearance risk into quality planning |

FAQ
Yes. Appearance boundaries can change tooling, polishing, plating, inspection, packaging, and scrap assumptions.
Usually not. Photos help, but drawings, visible-surface marking, finish target, and sample references are more reliable.
That is rarely efficient. Customer-facing areas, assembly areas, and hidden areas should be separated.
