01
Geometry & datums
Part envelope, datum strategy, wall transitions, draft, ribs, bosses, and access for tooling.
Drawing Review
Turn drawings, models, and samples into a quote-ready production plan.
Before quotation, JK Casting reviews 2D drawings, 3D files, samples, or worn parts for geometry, tolerances, material, machining stock, finish, and inspection. The goal is a quote-ready production plan with missing inputs identified before tooling or sampling.

Review scope
What our engineering team checks before quotation.
The goal is not to redesign your part. It is to surface manufacturing risk, confirm assumptions, and make the quoted scope clear.
02
Tolerance feasibility
Critical dimensions, geometric controls, fit relationships, and tolerance stack-up.
03
Casting allowances
Shrinkage, machining stock, parting direction, cores, fillets, and likely process route.
04
Material definition
Grade, heat treatment, hardness, equivalencies, and certificate requirements.
05
Finish requirements
Coating system, masking zones, surface condition, appearance, and corrosion exposure.
06
Inspection plan
Critical features, sampling level, gauges, reports, traceability, and packaging controls.
Technical evidence before production
Accepted inputs
Start with the information already available.
A complete drawing package is helpful, but it is not required for the first review. Send the strongest evidence you have and identify anything that is still uncertain.
✓2D drawing with dimensions and notes
✓3D model for geometry review
✓Physical sample or clear sample photos
✓Target material, quantity, and application
✓Critical fit, load, wear, or sealing conditions
✓Known finish, inspection, and packaging needs
Practical workflow
A practical review workflow from evidence to quotation.
1
Receive evidence
Drawings, CAD, samples, photos, notes, and quantities.
2
Review manufacturability
Confirm route, stock, access, tolerances, and open questions.
3
Clarify the scope
Resolve assumptions and record critical production requirements.
4
Issue the quotation
Quote the defined process, inspection scope, lead time, and commercial terms.
Deliverables & controls
What you receive from the review.
Document the technical basis so purchasing, production, inspection, and shipment use the same requirements.
Clarified quotation basis
A concise summary of the files, revisions, assumptions, and exclusions used for pricing.
Manufacturing route recommendation
A practical proposal for casting, machining, fabrication, finishing, and inspection.
Open-item list
Questions that must be resolved before tooling, sampling, or production release.
Traceable handoff
Approved drawings and technical notes stay linked to the production and inspection plan.
Frequently asked questions
Questions buyers ask before release.
Use these answers as a starting point. Final acceptance criteria should be tied to the drawing, purchase order, and approved technical record.
Can you quote from a sample without a drawing?+
Yes. Clear photos, dimensions, material clues, application details, and the physical sample can start the review. A production drawing may still be required before release.
Do you modify customer drawings?+
We can flag manufacturability issues and suggest practical changes. Customer approval is required before any production definition changes.
Which file formats can you review?+
Common formats include PDF, DWG, DXF, STEP, STP, and IGES. Native CAD can be discussed case by case.
How are drawing revisions controlled?+
The quoted revision and later approved revision should be recorded explicitly so purchasing, production, and inspection use the same technical basis.
