Quality Process
Inspection planned around your drawing and order
During technical review and quotation, we confirm the project's material, critical dimensions, heat-treatment requirements, inspection scope, sampling and shipment documents. Production and inspection follow the agreed requirements.
Mark critical characteristics and acceptance requirements on the drawing.
Before Production
Agree the acceptance requirements first
The drawing is the inspection basis, but revision, critical characteristics, sampling and document requirements still need to be agreed before production.
- 01
Drawing and revision
We confirm the applicable drawing revision, units, material callout and technical notes. If the 2D drawing and 3D model conflict, production follows the requirement confirmed in writing.
- 02
Critical requirements
Identify critical dimensions, geometric requirements, mating surfaces, finish requirements and target hardness after heat treatment. Requirements that are not stated should not be assumed.
- 03
Inspection scope
We agree inspection items, sampling, measurement methods and acceptance criteria for the part. State any full-inspection requirement before quotation.
- 04
Records and documents
Request dimensional, hardness, heat-treatment or material records, report templates or shipment copies with the RFQ. Availability and format are confirmed in the quotation.
Project Workflow
From review to shipment
Each stage follows the agreed drawing, order and inspection arrangement.
- 01
Requirement review
Review the drawing, material, quantity, requested delivery date and acceptance requirements, and identify items that need clarification.
- 02
Agree inspection arrangements
Define critical characteristics, inspection stages, sampling frequency and shipment documents in the quotation or order.
- 03
Incoming checks
Incoming checks are arranged to the order requirements. Material information to be checked and the record format are defined for the project.
- 04
In-process checks
During machining and heat treatment, agreed process and inspection points are checked, with key results recorded where required by the project.
- 05
Final inspection
Finished parts are inspected against the drawing, order and agreed inspection scope. Sampling or full inspection follows the project agreement.
- 06
Shipment review
Before shipment, quantity, identification, packaging and agreed documents are checked. Estimated lead time and shipping arrangements follow the order confirmation.
Inspection Scope
Inspection is project specific
Inspection varies with part geometry, quantity and application. It does not mean every characteristic is checked on every part by default. Tolerance capability also depends on the feature, size, material, heat treatment and measurement method, and is confirmed after drawing review.
- Dimensions and geometry
- Drawing dimensions, fits and geometric requirements. Mark critical characteristics clearly.
- Visual and surface requirements
- Appearance, burr condition, surface condition and other stated requirements.
- Hardness and heat treatment
- Target hardness, test locations, frequency and record format are agreed before production.
- Shipment review
- Quantity, part identification, packaging requirements and agreed documents.
Documents and RFQ
Need inspection documents? Specify them with the RFQ
Document requirements vary by buyer. State the document name, content, language, template and delivery method with the RFQ. Availability and format are subject to the written quotation.
Help us review your RFQ accurately
Complete information helps us define the manufacturing scope, inspection plan and estimated lead time.
- 2D drawing, 3D model and revision
- Material grade, supplied condition, quantity and repeat demand
- Critical dimensions, tolerances and fits
- Heat-treatment requirement, target hardness and test locations
- Surface, burr, marking and packaging requirements
- Inspection scope, sampling, document format, destination and requested delivery date
Start With Your Drawing
Send the acceptance requirements with your drawing
Send material, quantity, critical requirements, required documents and requested delivery date with the drawing. The quotation will confirm manufacturing scope, inspection arrangements and estimated lead time after review.
The current RFQ form opens an email draft. Attach your drawings before sending.
