Manufacturing Quality Assurance

Quality Control for Custom Parts

GD Prototyping combines material checks, in-process inspection, and final verification for rapid prototyping and low-volume manufacturing, guided by your drawings and agreed acceptance criteria.

  • Dimensional Inspection
  • Reports on Request
  • NDA Support

Quality Commitment

Clear Requirements. Measurable Results.

Manufacturing quality control starts with clear requirements. We review the features that affect fit and acceptance, then match inspection methods and documentation to the part and production stage.

Requirements Before Production

Review drawing revisions, critical dimensions, material specifications, and cosmetic expectations before manufacturing begins.

Measurement Matched to the Part

Use CMM inspection and suitable gauges to check dimensions and geometric features against drawing requirements.

Checks During Manufacturing

Inspect selected features during production to identify deviations while corrections are still practical.

Project-Specific Documentation

Agree report formats and material documentation early so your receiving team knows what records to expect.

Critical Feature Checks Inspection Reports Available Engineering Support Defined Acceptance Criteria

Quality Management Process

Inspection from Material Receipt to Shipment

1

Material Verification

Confirm the specified material and review available supplier documents before processing.

2

First Article Inspection

Check initial parts against selected drawing requirements before continuing the production batch.

3

In-Process Inspection

Check selected dimensions at planned stages using methods suited to the manufacturing process.

4

Final Inspection

Review finished dimensions and appearance against the agreed acceptance criteria.

5

Shipment Review

Check required documents, part identification, and protective packaging before shipment.

Critical Feature Focus

Prioritize dimensions that affect fit, assembly, or specified function.

Drawing Revision Control

Use the agreed drawing revision to define inspection requirements.

Deviation Review

Review out-of-tolerance findings and determine the appropriate corrective action.

Receiving Inspection Support

Organize agreed inspection information to support your incoming checks.

Incoming Material Inspection

Confirm Materials Before Manufacturing

Incoming material inspection checks the specified grade, stock condition, and available documentation before processing. Material verification follows the requirements of your part and manufacturing route.

  • Material Document ReviewReview available certificates against the specified material grade and project documentation requirements.
  • Visual & Surface ChecksCheck incoming stock for visible damage, corrosion, and surface conditions that could affect processing.
  • Stock Size VerificationConfirm stock dimensions and machining allowances against the planned manufacturing route.
  • Material Identification & TraceabilityRecord material identification and available batch references to support the agreed traceability scope.

In-Process Quality Control

Check Features While Production Is Underway

In-process inspection checks selected features before later operations make corrections more difficult. Inspection points reflect the part geometry, manufacturing process, and critical dimensions.

  1. 01Review the SetupConfirm part orientation and measurement access before checking selected features.
  2. 02Measure Selected FeaturesCheck dimensions at inspection points suited to the part and process.
  3. 03Review the ResultsCompare measurements with drawing tolerances and flag deviations.
  4. 04Correct & RecheckReview deviations, apply agreed corrections, and recheck the affected features.

Final Inspection & Validation

Review Finished Parts Before Shipment

Final inspection brings dimensional results and cosmetic requirements together. We review the agreed inspection scope, outstanding findings, and shipment preparation before releasing parts.

  • Dimensional & Geometric Checks
  • Surface & Appearance Review
  • Part Identification & Protective Packaging

Inspection Equipment

Equipment for Dimensional & Surface Inspection

Our inspection equipment includes ZEISS and HEXAGON CMMs, optical measuring systems, and precision gauges. Measurement methods follow the feature geometry, tolerance, and access requirements.

Quality Documentation

Inspection Reports & Supporting Records

Request dimensional inspection reports, CMM measurement results, and available material documentation to support your incoming inspection. Confirm reporting formats and traceability requirements during quotation so the documentation scope is clear before production.

Contact our team to confirm the documentation and sample records available for your project.

Confidentiality & Data Protection

Confidentiality for Your Custom Part Projects

GD Prototyping supports NDA agreements for customer projects and participating suppliers. Define confidential information and disclosure restrictions before sharing sensitive drawings or manufacturing details.

  • NDA Before DisclosureRequest a confidentiality agreement before sharing sensitive design information.
  • Confidential Project InformationInclude CAD files, drawings, specifications, and production information within the agreed confidentiality scope.
  • Supplier Disclosure RequirementsReview restrictions on sharing project information with suppliers involved in manufacturing.
  • Images & Public ReferencesSpecify permission requirements for product photography, case studies, and references to your company.

Quality FAQs

Custom Part Inspection Questions

How is inspection planned for custom parts?

Your drawings, critical dimensions, material, finish, and order quantity guide the inspection methods and reporting scope.

Can I request dimensional inspection reports?

Yes. Specify dimensional reports, CMM results, or material documents when requesting a quote so availability, scope, and format can be confirmed.

Do you inspect every part and dimension?

Inspection coverage follows the agreed plan. Sampling, critical-feature checks, and any full-inspection requirements are confirmed before production.

How are non-conforming parts handled?

We verify the deviation against the agreed requirements and coordinate appropriate corrective action. Any change to acceptance criteria needs your approval.

Define Your Quality Requirements Before Production

Send your CAD files, drawings, and critical inspection requirements. Our team will review manufacturing feasibility and the inspection documentation needed for your project.
