QUALITY ASSURANCE

TDB Hanoi uses state-of-the-art, fully automated CMMs (Coordinate Measuring Machines), Romer arms, and powerful PC-DMIS (Personal Computer – Dimensional Measuring Interface Standard) software to measure and verify critical external and internal part dimensions, complex geometry, overall machine tool output, and other vital features as specified. Machinists and quality assurance people use gages and other instruments for in-process testing and verification. The company manages over 6,000 gages used in a wide range of machining process validation. An outside IEC 17025 accredited calibration facility oversees our rigorous calibration system. All of our facilities are climate controlled at 70°F ±2° with relative humidity below 40% to ensure a stable testing and manufacturing environment.

As a Tier 1 source, TDB Hanoi will manage and provide inspection on all aspects of your manufacturing process. Including Thermal: heat treating, induction hardening | Coatings: chrome, plating, anodize, phosphating, painting | EDM (Electrical Discharge Machining): wire, sinker | Deep Hole Processing: gun drilling, honing | Gear Cutting and Grinding: helical, spline | Surface Finish: superfinishing, micromachining, microfinishing | Machined Part Balancing | Porosity Impregnation: castings, powdered metal, weldments | Welding: traditional, friction.

Operator inspection dimension metal parts by CMM after machining process in industrial factory.

Our Capabilities

A process engineer or quality technician generates CMM programming to read and verify critical component markers established by our engineering evaluation process. Machined parts or assemblies rest upon or are affixed to the stationary granite measurement table, or held in place by use of a fixture. The CMM probe travels on the Z, Y, and X-axis precisely interacting with the part as the PC-DMIS programming dictates, recording every marker and bringing alert if an issue is present. Machining parameter adjustments quickly result when observing variation in the machining process. The CMM testing process successfully measures and verifies even the most complicated part geometry.

Inspection Definitions

Calibration – Comparison of an instrument against a known standard. Calibration includes repeatability checks, adjustments, etc.
FAI – First Article Inspection
FMEA – Failure Modes Effects Analysis
Instruments – Measuring or test equipment, either mechanical or electrical; this includes “tool,” “gauge,” “test equipment,” and “standards.”
Instrument Identifications – All Trace-A-Matic standards and instruments used for product acceptance are assigned a unique identification number. Devices may be marked, scribed, labeled, or color-coded with the I.D. number.
ISIR – Initial Sample Inspection Report
PPAP – Production Part Approval Process
Product Acceptance Inspection – The inspection operation, after which the product goes directly to the internal/external customer or into stock, is termed “Product Acceptance.”
Soft Gages – Gages machined in-house for a specific product or characteristics.
Source Inspection – A customer representative visits Trace-A-Matic to serve as an outside quality inspector.
Standard – Serves as a master device used for purposes of comparison of known dimensions or characteristics.
Verification – A functional check of an instrument checking the instrument against a calibrated standard. Verification does not involve repeatability checks or adjustments.
Virtual Inspection – A customer representative performs a quality inspection at Trace-A-Matic remotely over a secure communication platform.
