QUALITY APPROACH

Make quality risks visible before production.

Agree acceptance criteria, inspection records and how deviations will be handled before production.

Drawing controlInspection planRelease records
ORDER EVIDENCE

Three points to agree before production.

Marked-up technical drawing used for requirement review

Drawing review

Revision, dimensions, material and critical characteristics are clarified before production.

Clean CNC machining cell at an independent partner manufacturer

Production route

Processes and supplier suitability confirmed for the part.

CMM dimensional inspection reference

Inspection evidence

Features, methods, sampling and required records.

MANUFACTURING REFERENCE PHOTOGRAPHS

The production route is selected for the drawing.

We match the manufacturing route to the drawing, material, quantity and required processes.

Five-axis equipment referenceUse of a multi-axis route depends on tool access, workholding, geometry, tolerance, quantity and inspection needs.

Partner production environmentThe proposed manufacturer and process route are reviewed against the released drawing before commitment.

Equipment and inspection methods are confirmed for each order.

INSPECTION REFERENCE PHOTOGRAPHS

Inspection resources are matched to the drawing.

Before production, we agree which features to measure, how they will be checked and which records you need.

Coordinate measurement reference: supplier-provided reference photograph

Manual measurementSuitable instruments and the measurement basis depend on the feature, tolerance and agreed inspection plan.

Supplier-provided equipment photographs are inspection references, not evidence of a Molitech-owned facility or a completed inspection. Equipment and inspection methods are confirmed for each order.

PROCESS MONITORING

Follow the process, not only the final result.

Liwen's supplier-quality background supports practical follow-up during production: open questions, agreed checkpoints, deviations and corrective actions are kept visible.

  • Drawing and change control
  • Agreed production checkpoints
  • Exception and corrective-action follow-up

Liwen's professional experience includes on-site process review and supplier follow-up.

INSPECTION RECORDS

What supports a useful inspection record?

CMM probe measuring a representative machined component

Coordinate measurement

CMM method and reporting scope are matched to the controlled features.

Manual inspection setup used as a measurement record reference

Manual inspection

Gauges, features and actual readings follow the agreed inspection plan.

Inspection workstation used as a traceability record reference

Record traceability

Results identify the part or batch, drawing revision and inspection basis.

Ballooned characteristics

Numbered characteristics connect the released drawing to the inspection record.

PROJECT COORDINATION

One contact to keep the order on track.

  • Open technical questions consolidated
  • Milestones and changes communicated
  • Inspection and shipment evidence checked
  • Exceptions raised before release

QUALITY THROUGH THE ORDER

Clear checks. Clear responsibilities.

The manufacturer performs

The selected manufacturer produces the parts and carries out the inspections and records assigned to it in the agreed order requirements.

Molitech coordinates and reviews

Liwen follows up on required checks, reviews the agreed records and coordinates investigation and corrective action when results do not meet the order requirements.

You approve design changes

Manufacturing questions and proposed deviations are submitted for your decision. Your approved drawing and agreed acceptance criteria remain the production baseline.

On-site visits, independent inspection, full inspection and specialist reports are included only when their scope, availability and cost have been agreed for the order.

Tell us what matters for your part.

Send the drawing and any critical inspection or documentation requirements with your enquiry.

Discuss Your Machined Part
BEFORE THE FIRST ORDER

Review the quality scope for one drawing.

Agree critical features, measurement methods, batch records and deviation handling. This checklist is a review tool, not a completed inspection report.
