# Zinc Die Casting RFQ Checklist: Everything to Send and Compare
Blog Article
1. Why an Incomplete RFQ Produces a Misleading Quote
A casting quote is only as dependable as the package behind it. When buyers send a photo, a rough model, or a target price without drawings and volume, shops estimate broadly, pad for unknowns, and return numbers that fall apart at trial. This zinc die casting RFQ checklist lists the documents, commercial inputs, quality requirements, tooling questions, and quote-line items a serious request needs, so every supplier prices the same part on the same basis. Put an hour completing the package before sending it; the precision removes revision rounds later and makes competing quotes genuinely comparable.
A structured zinc die casting RFQ checklist also levels the playing field: a small buyer with complete paperwork receives the same engineering attention and fairer pricing as a high-volume account, because the supplier can quote without spending hours chasing missing dimensions.
Gather a one-page intake summary next to the files: part name, usage, target market, special compliance needs, and the decision owner; this summary lets an engineer respond in the first pass instead of asking back for context hidden in a long email thread.
## 2. Documentation Package: Send the Engineering Truth
Send the technical set:
- A 3D model or STEP file showing full geometry, including hidden bosses, ribs, and undercuts.
- A controlled 2D drawing with dimensions, GD&T, datum references, and surface finish callouts — a model alone lacks tolerances.
- Named alloy or a performance target (strength, wear, temperature, corrosion) if grade is undecided.
- Cosmetic zones, appearance masters, or reference photos for visible faces.
- Mating-part interfaces and assembly notes, so gates and ejector marks avoid fit areas.
Absent drawings force the supplier to guess dimensions, and every assumption becomes a disagreement at first article; send revisions labeled by number so the current print is never ambiguous.
Include section views, internal thread depth, insert bosses, and any hidden undercut the model may hide; photos of a similar part help but never replace dimensions. If a standard catalog item adapts your design, mark which dimensions are fixed and which may flex under DFM.
Prefer neutral STEP or Parasolid formats rather than native CAD files that require a specific version, and include PDF drawings alongside; suppliers estimate faster when files open on first try, and missing native-version requests delay the whole RFQ.
## 3. Commercial Inputs: Volume Drives the Economics
Casting economics turn on volume, so share it honestly rather than hiding it:
- Target annual quantity, lifetime program volume, and a realistic forecast ramp.
- Initial bridge or sample quantity needed before full production.
- Target piece price or budget range when known; silence on price leaves room for wide estimates.
- Required launch date, seasonal window, and any milestone deadline.
- Shipping destination and Incoterm preference, so freight and duties enter the model.
Volume decides cavity count, tooling investment, and tiered pricing; a single-digit estimate underprices multi-cavity tooling, while an inflated forecast overbuilds a die.
Provide a one-to-three-year ramp rather than only this year's number; a supplier reserves capacity and proposes cavity count against trajectory, and an honest low start with realistic growth avoids overbuild while protecting future price.
## 4. Finish, Inspection, and Acceptance Requirements
Describe the cosmetic standard and how it will be accepted:
- Surface route: bright nickel-chrome, satin nickel, painting, powder coating, passivation, or as-cast.
- Critical-to-quality dimensions, gauges or fixtures, and sampling frequency.
- Required certificates: lot chemistry, material certs, RoHS, REACH, ISO 9001 evidence, or IATF 16949/PPAP where the market demands.
- Appearance master, allowed defect limits, and salt-spray or adhesion expectations.
- Packaging, labeling, marking, and any assembly or hardware insertion scope.
If acceptance criteria live only in the buyer's head, first articles fail on interpretation rather than on metal; putting them on the RFQ aligns the control plan before the die is cut.
For regulated markets, attach the exact declaration expected rather than asking for generic compliance; specify RoHS/REACH language, reporting cadence, and whether each lot needs a material certificate or only periodic declarations.
Attach a photo or sample for the cosmetic face, and define what counts as an acceptable mark, scratch, or texture variation; plating magnifies surface differences, so a written appearance master prevents subjective rejection at inspection.
## 5. Tooling and Ownership Questions to Ask Up Front
Tooling is the main capital investment, so define it in the request:
- Who owns the die, who pays for it, and where it is stored.
- Expected die life, maintenance schedule, and wear-part responsibility.
- Release and portability rights if the program moves.
- Trim tool, checking fixture, and machining fixture costs separated from casting price.
- Revision cost when the drawing changes after approval.
Written answers here prevent a supplier from retaining the tool hostage later and make exit rights clear from day one.
Request what counts as normal wear versus buyer-induced damage, how wear parts are charged, and whether photos or samples accompany a wear claim; these terms keep maintenance disputes factual rather than negotiable at the wrong moment.
## 6. What a Complete Quote Should Contain
When proposals return, confirm that each one shows:
- Per-piece cost at your stated annual volume, with tiered breaks for growth.
- Separate tooling cost, maintenance terms, and amortization option.
- Finish, machining, inspection, and packaging line items rather than a bundled lump sum.
- Written here lead times for tooling design, trial casting, first-article approval, and ramp-to-batch.
- MOQ, sample policy, and first-article report scope.
- Allocated capacity evidence for your forecast, not generic equipment lists.
A transparent zinc die casting quote lets you compare driver by driver instead of comparing a rounded total that hides where money goes.
Request a sample or first-article policy in writing: who pays for samples, how many pieces, and whether trial material is included in tooling; surprises here inflate the first PO.
Ask also for a capacity statement for your quarter: typical shift structure, reserved hours, and recent output on comparable parts, rather than a list of machine tonnage that proves nothing about available slots.
## 7. Compare Total Landed Cost, Not Piece Price
The lowest piece price rarely wins the real budget . Assemble a total-landed-cost model: piece price plus tooling amortization, finish, machining, inspection, freight, tariffs, inventory carrying, and quality-escape risk. Add a transparent alloy-index clause so raw-material swings are shared fairly, and price the same quantity, finish, and acceptance standard across bidders. A quote that bundles finishing into a vague number cannot be compared with one that lists plating separately, so request the breakdown before choosing.
Use the zinc die casting RFQ checklist to compare alloy-index mechanisms too: fixed price windows, capped surcharges, or pass-through clauses each protect the budget differently, and the chosen method matters across a 12–24 month program.
Prepare one short comparison sheet listing each bidder's piece price at matched volume, tooling, finish, lead time, and capacity note; a side-by-side sheet makes gaps visible and prevents a persuasive sales call from outweighing the numbers. Bring the same questions to every supplier so answers can be matched line by line.
## 8. Red Flags Hidden in a Casting Quote
Beware for proposals that avoid substance: no DFM notes despite complex geometry, a single vague lead time with no stage breakdown, missing tooling ownership terms, no cavity or capacity evidence, bundled cost lines, refusal to share alloy certificates, or pressure to commit before reviewing the drawing. A shop that quotes from a photo alone, promises the tightest tolerance on every face, or dismisses your finish standard should earn deeper verification before award; those signals predict problems at trial rather than savings.
Also compare how the shop responds: timely written answers, DFM questions that show real understanding, and a named engineer on the thread predict smooth production; a fast but generic reply matches a vague quote.
Compare how each bidder treats DFM: a supplier that returns suggestions rather than only a number will protect the program at trial, while one that skips review invites rework quotes after deposit.
## 9. RFQ Timeline and Smart Follow-Up
Allow a realistic review window: send the package, request written questions, hold a short engineering call on complex parts, and allow time for DFM comments before comparing numbers. Follow up in writing on open items, keep every revision dated, and record who said what. For reference, KEENOVIS plans net castings of about 0.5 g–2.0 kg on 45–168 t hot-chamber machines, with as-cast critical features around ±0.05–0.15 mm and selected CNC interfaces near ±0.01 mm after machining; confirming your part sits inside that window narrows the supplier field quickly.
Pick a single owner for the RFQ thread so questions route to one person, store every revision and reply in one folder, and avoid mixing drawing versions across email threads.
Keep a written decision record after review: which quote won, why, which risks were accepted, and when to revisit pricing at volume breaks; this record protects the program when personnel change and gives finance a traceable basis for the tooling investment.
## 10. Send Your RFQ to an Engineering-Responsive Team
KEENOVIS coordinates die design, casting, finishing, inspection, assembly, and packaging through one team, providing DFM comments on walls, draft, ribs, bosses, gates, ejector marks, and cosmetic zones before tool release; confirming ZAMAK 3, ZAMAK 5, ZAMAK 7, ZA-8, high-fluidity zinc, or your specified grade; and building CTQ plans aligned to your acceptance criteria; whether your zinc die casting RFQ checklist covers one part or a full program, the team aligns capacity, finish capacity, and inspection records to your forecast so reorders match the first approved article. Use this zinc die casting RFQ checklist to package your program, then request a quote with the model, drawing, volume, and finish standard attached.
## 11. Frequently Asked Questions
### What documents must a zinc die casting RFQ include?
A 3D STEP model, controlled 2D drawing with GD&T and tolerances, named alloy or performance target, cosmetic zones, annual volume, finish standard, acceptance criteria, packaging, and deadline.
### Why does annual volume appear in a casting RFQ?
Volume decides cavity count, tooling investment, and tiered unit price; without it, every supplier estimates differently and the quotes are not comparable.
### Should I state my target price in the RFQ?
Yes, when known; a budget range guides feasible tooling and finish choices and filters proposals that fall outside your program economics.
### What tooling questions go into an RFQ?
Ownership and payment, storage, die life and maintenance, portability on exit, revision cost, and whether trim and checking fixtures are priced separately.
### How do I compare casting quotes fairly?
Model total landed cost — piece price, tooling amortization, finish, machining, inspection, freight, tariffs, and quality risk — at identical volume, finish, and acceptance standard rather than comparing bare piece price.
### What is a red flag in a casting quotation?
Absent design review, vague single-stage lead time, bundled cost lines, missing tooling terms, refusal to share alloy certificates, or pressure to commit before drawing review.
### When should an engineering call follow the RFQ?
On complex geometry, tight cosmetic zones, or uncertain grade; a written call agenda and dated follow-up notes prevent assumptions from becoming first-article disputes.
