TOOLING & SAMPLE APPROVAL
Tooling & Sampling
Connect tooling decisions, sample evaluation and approval records before repeat production begins. The exact route is defined by the selected manufacturing process, part geometry, production quantity and customer acceptance requirements.

SERVICE OVERVIEW
Connect the service scope to the finished-part requirement.
Tooling is part of the production system, not a separate purchasing item. Tool concept, parting strategy, allowance, datums, expected production quantity and maintenance responsibility can affect cost, sample performance and later repeatability.
During the sampling stage, the part is evaluated against the agreed drawing revision and inspection scope. Required dimensional records, material documents and functional checks should be identified before tooling starts. Sample approval then provides a controlled basis for production release and later drawing revisions.
CUSTOMER INPUTS
Information required for an actionable review.
Incomplete requirements can change the quotation, process route and inspection scope. These inputs help identify open items before production planning.
Controlled drawings and 3D data
Current revision, critical dimensions, datums, tolerances and any model-to-drawing precedence.
Material and manufacturing route
Required grade or specification and the proposed casting, forging or machining route.
Quantity expectations
Prototype need, initial order quantity and expected repeat or annual demand where available.
Sample acceptance requirements
Dimensions, material records, appearance, functional checks and documentation required for approval.
Tooling commercial requirements
Ownership, identification, storage, maintenance, change control and any transfer conditions to be agreed.
SERVICE SCOPE
Available work is confirmed by project, not by a generic checklist.
The execution route may combine Tianluping operations and controlled specialist suppliers. The quotation defines what is included.
Tooling feasibility review
Review geometry, parting, draft, cores, inserts, machining allowance, datum strategy and risks relevant to the selected process.
Project-definedTool concept and quotation basis
Define the tooling route, included components, expected sample stage and commercial scope before release.
Project-definedTool manufacture and trial
Coordinate tool manufacture, initial trial conditions and identified corrections according to the approved scope.
Project-definedSample production
Produce evaluation samples using the agreed material, drawing revision and planned manufacturing route.
Project-definedSample inspection and review
Compare agreed characteristics with the applicable drawing and prepare the records included in the quotation or quality plan.
Project-definedRevision and production release
Record approved changes and establish the released basis for repeat production after customer authorization.
Project-definedPROJECT WORKFLOW
Review, approve and control the service route.
The exact milestones depend on the project, but responsibility and acceptance should be visible before production begins.
Requirements review
Review the drawing, material, quantity, process choice, critical features and sample deliverables.
OutputOpen-item list and quotation basisTooling plan
Define the tool concept, interfaces, responsibility, milestones and review points appropriate to the process.
OutputConfirmed tooling scopeManufacture and trial
Build or coordinate the tooling and conduct initial trials to identify filling, forming, dimensional or release issues.
OutputTrial parts and correction recordSample validation
Produce and inspect samples against the agreed revision and submit the project-specific records.
OutputSamples and agreed inspection evidenceApproval and release
Record approved corrections and release the controlled tooling and production basis after customer approval.
OutputApproved production basisDELIVERABLES & RESPONSIBILITY
Agree what will be supplied and what evidence is required.
Deliverables are project-specific and should be included in the quotation, approval plan or quality agreement.
PROJECT QUESTIONS
Questions to clarify before quotation.
Who owns the tooling?
Ownership and related rights should be stated in the accepted quotation or tooling agreement. Payment for tooling should not be treated as the only definition of ownership, storage or transfer responsibility.
What is required before tooling starts?
A controlled drawing or model, material requirement, expected quantity, critical characteristics, sample acceptance scope and resolved commercial assumptions are normally required.
Does a sample automatically approve mass production?
No. Production release should follow the agreed customer approval method and reference the approved sample condition, drawing revision and any accepted deviations.
Can tooling be revised after the first trial?
Trial findings may require correction or optimization. The technical effect, responsibility, cost and schedule impact should be reviewed before a tooling change is authorized.
ENGINEERING REVIEW
Define the complete scope before quotation.
Share the drawing, material, quantity, application and required records. The team can review the manufacturing and supporting-service route together.
