INSPECTION EQUIPMENT & QUALITY VALIDATION
Zhongde selects inspection methods according to drawing CTQs, datum relationships, tolerance levels and product function. Beyond dimensional and geometric inspection, hardness, torque and axial-clearance checks are used to confirm actual functional requirements.

WHAT WE VALIDATE
From part dimensions, GD&T and profiles to material condition, assembly clearance and operating torque, Zhongde defines inspection plans according to drawing CTQs and final functional requirements.
Dimensional conformity is the foundation; assembly and functional results are the final validation.
Primary Equipment
CMM and general measuring instruments
Typical Applications
Housings, flanges, bearing seats, locating structures and complex precision-machined parts
Verify individual dimensions and geometric relationships between multiple datums.
Primary Equipment
Optical profile projector
Typical Applications
Thin-wall parts, small precision components, stamped or machined profiles and complex edges
Use optical methods for fine features that are difficult to access with a CMM probe.
Primary Equipment
Hardness testers
Typical Applications
Aluminum alloys, steels, stainless steels, heat-treated and surface-hardened parts
Dimensional conformity alone does not confirm material or heat-treatment condition.
Primary Equipment
Torque tester and axial-clearance tester
Typical Applications
Robot joints, bearing assemblies, rotating mechanisms and precision modules
Confirm expected function through torque, clearance and operating-condition validation.
INSPECTION METHOD SELECTION
The method is not determined by equipment alone. It is defined by CTQ type, tolerance level, datum system, part geometry and final function.
01
Confirm tolerances, datums and specifications
02
Determine critical dimensions and functional risks
03
Match suitable equipment and measurement techniques
04
Confirm drawing and application requirements
INSPECTION EQUIPMENT & APPLICABLE CTQS
Zhongde selects inspection equipment according to CTQ type, tolerance level, datum system and product function. Different systems validate dimensions and GD&T, 2D profiles, material hardness, torque and axial clearance.
Equipment quantity is only the foundation; reliable results depend on matching the correct method to each CTQ.

INSPECTION PLANNING & VALIDATION WORKFLOW
Inspection planning starts from product function and combines CTQs, datum systems and quality risks to define the measurement method, fixture, measurement points, inspection frequency and record requirements. The objective is to produce comparable and traceable results that support release and improvement.
First define why the measurement is needed, then decide what, how and when to measure.

Reliable inspection results come from the combined control of equipment, methods, datums, environment and personnel—not from equipment brand alone.
INSPECTION RESULTS & QUALITY RECORDS
Inspection results are linked to drawing revisions, part batches, inspection equipment, inspection dates and acceptance decisions to maintain traceable and reviewable quality data.
Results cover dimensional accuracy, material and process status, assembly function and in-process quality evidence.
Relevant inspection records and quality reports are provided according to customer requirements, CTQ level and production stage.
Records first-article results, acceptance status and review information.
Records measurements, specifications, tolerances and decisions.
Records datum relationships, GD&T results and key deviations.
Records hardness values and related material or process status.
Records torque, axial clearance and functional measurement results.
Records deviations, corrective actions and reinspection results.
Important Note： Report format, inspection scope and submission frequency are defined by customer requirements, CTQ level, production stage and project agreement. Not every order includes every report by default.
RFQ & INSPECTION REQUIREMENTS
Complete drawings, CTQ definitions and reporting requirements help confirm inspection feasibility, cost and deliverable scope before production.
