Neway Quality Assurance

Quality assurance is critical for ensuring that products or services meet the desired level of quality, and for achieving customer satisfaction, brand reputation, compliance, cost savings, and continuous improvement.

PCDA System

The PDCA system plays a vital role in custom parts manufacturing by enabling continuous process improvement. It helps define requirements (Plan), execute machining steps (Do), inspect deviations (Check), and adjust designs or processes (Act). This cycle enhances quality control, reduces costs, and ensures consistent delivery, supporting standardized yet flexible production of non-standard components.

Phase	Key Function
Plan	Analyze customer specifications, functional requirements, and tolerances to develop detailed process plans, material selection, control checkpoints, and quality assurance strategies before manufacturing begins.
Do	Implement machining, assembly, and inspection operations according to the defined process plan, ensuring adherence to quality standards and operational efficiency throughout custom part production.
Check	Inspect critical dimensions, tolerances, and functional parameters; compare actual results to specifications to detect deviations, process errors, or material inconsistencies during or after production.
Act	Correct identified issues by modifying process parameters, tooling, or design; update technical documentation to reflect improvements, preventing recurrence and supporting continuous process standardization.

Optical Comparators for Profile Inspection in Custom Parts

Optical comparators enable non-contact profile inspection and dimensional verification of custom parts, especially small or delicate components. They enhance visual QC, template matching, and first article validation with high magnification accuracy.

Phase	Key Function
Non-Contact Dimensional Inspection	Projects enlarged profiles to precisely inspect features without contacting the part, ideal for fragile or miniature non-standard components requiring edge and contour validation.
Profile and Contour Matching	Compares actual part geometry to master overlays or CAD-derived templates to detect deviations in outlines, radii, chamfers, and internal contours.
First Article Inspection	Used to verify first-run parts against drawings by magnifying and measuring profiles to catch tooling or setup errors early in custom production.
Visual Quality Control	Enhances manual inspection by enabling visual comparison of critical features, helping operators identify surface flaws, burrs, or geometric inconsistencies quickly and reliably.
