Custom Metal Manufacturing: Enquiry, Samples and Repeat Orders
Plan a custom manufacturing order through enquiry, tooling, samples and shipment release. Keep drawings, approval records and repeat-order revisions aligned.
Discuss your requirements
A custom manufacturing order needs a sequence of decisions that connects the initial enquiry with the product eventually shipped. Drawings, samples, commercial terms and inspection requirements should refer to the same construction. Clear approval responsibilities help prevent an unresolved design question from becoming a production assumption.
Gairun's project discussion starts with the available product information and the buyer's requirements. The detailed route is agreed for the actual order. The milestones below connect each approval with the information needed to agree quantities, sample work and timing.
Identify the output of each project decision
| Stage | Decision to record before proceeding |
|---|---|
| Initial enquiry | Component, current development stage and requested supply scope |
| Manufacturing review | Proposed route, unresolved interfaces and quotation assumptions |
| Tool and sample approval | Drawing revision, sample construction and acceptance requirements |
| Production release | Approved configuration and closure of relevant sample findings |
| Shipment and repeat order | Required records, packing and change-control references |
Use these decisions to agree responsibilities with Gairun. A concept project may require further definition before a firm manufacturing proposal; a released drawing may move directly to reviewing the requested route. Any timing commitment should refer to the agreed inputs and approvals.
Define the enquiry package
Provide a drawing, model, artwork or concept with the intended use and expected quantities.
Explain which details are approved and which remain open. A manufacturer can make more useful suggestions when it knows the function or appearance that must be preserved.
Include mating components and operating conditions where they affect suitability.
A housing needs its assembly interfaces, a buckle needs its strap and a perfume cap needs the relevant bottle and pump. These details can determine the route more strongly than the external shape.
State the required supplied condition.
Loose castings, finished components, subassemblies and packaged products are different orders. Identify the attachments, purchased parts and packaging that should be included in the review.
Add the destination market, required records and delivery objective.
Clarify whether the date means dispatch or arrival at the buyer's facility. The contact page lists the information needed for a focused manufacturing enquiry.

Resolve feasibility and quotation scope
The technical review should identify suitable materials, tooling, secondary operations and finishing.
Proposed changes that affect the product should be explained and approved. A supplier's suggestion is not a released design until the responsible buyer or engineer accepts it.
The quotation should distinguish tooling, samples, recurring production and other relevant costs.
It should also identify assumptions, exclusions and the supplied components. This makes the proposal easier to compare and reduces uncertainty when the order is placed.
Confirm the practical supply route for important operations.
Where machining, finishing or testing involves another provider, agree who controls the specification and accepts the result. The buyer should understand the commitments actually being offered.
Use the sourcing guide to compare equivalent scopes.
A lower unit price is not necessarily a better offer if it omits the finish, inspection or assembly needed for the product to be usable.
Approve tooling and sample requirements
Release a controlled product definition before tooling work begins.
The model, drawing and artwork should agree on the current revision. Resolve conflicting dimensions or visual details instead of relying on an informal preference for one file.
Define the sample stages and the questions each will answer.
A fit model, trial casting and finished approval sample can serve different purposes. The plan should state which evidence is required before the next investment or production step.
Agree tooling ownership, storage and revision terms in the commercial arrangement.
These are project-specific matters and should not be assumed from a tooling charge alone. The tooling page explains the technical decisions that accompany those terms.
If the project has customer-specific testing or documentation requirements, include them before sampling.
Adding a major qualification program after the tool is complete can change the schedule and the suitability of the proposed supplier route.
Close sample findings before production
Evaluate the sample against the agreed drawing, appearance reference and functional requirements.
Record results in a way that identifies the tested construction and revision. A photograph approval should not be interpreted as approval of dimensions or tests that were never reviewed.
Describe corrections precisely and determine which checks must be repeated.
A new finish can affect fit, while a revised attachment can affect retention. Keep the change record connected to both the sample and the production definition.
The final approval should identify any accepted deviations and their scope.
A temporary sample difference should not become a permanent production change by accident. The sampling page provides a framework for reaching a clear release decision.
Confirm that the purchase order reflects the approved configuration.
Quantities, versions, packaging and required reports should match the agreed scope. This is the point at which technical and commercial definitions need to converge.
Coordinate inspection and shipment release
Agree the checks and documents required before shipment.
Incoming, first-article, process and final inspection serve different purposes. The plan should focus on the characteristics that determine whether the supplied product can be accepted.
If third-party testing is required, identify the specimen, method, criterion and approval owner.
Testing should represent the final relevant construction. A report for another material or finish should not be treated as automatic evidence for the current order.
Packing should preserve the accepted condition and identify the correct variants.
Include accessories, labels and any customer-specific arrangement in the release check. A correctly manufactured part can still create problems if it arrives mixed, damaged or without the agreed documentation.
Confirm transport responsibilities and required shipment information separately from production completion.
The route and trade terms should be agreed for the actual destination and order. They should not be inferred from an unrelated previous transaction.
Control repeat orders and revisions
A repeat order should reference the approved design and finish unless a change is intended.
Check whether the buyer's mating components or market requirements have changed. The metal part may remain identical while the surrounding acceptance conditions differ.
Proposed material, tool, finish or process changes should follow the agreed notification route.
Determine whether samples, inspections or tests need to be repeated. This keeps cost or production adjustments from silently undermining earlier approvals.
Maintain clear identifiers for variants and superseded revisions.
Service and purchasing teams should be able to distinguish the component they need without relying on appearance alone. The factory review page explains how records connect with the production handoffs.
Send Gairun your project files and current development stage to establish the next decision, the evidence required and the scope that can be reviewed for a custom manufacturing order.
