QA & Inspection Equipment

MAPT operates complete production and QA inspection equipment to guarantee plating quality.

Our ISO/IEC 17025 accredited QA center and laboratory run atomic absorption spectrometry, X-ray coating thickness measurement, and Hull cell testing, with bath chemistry and coating quality monitored by dedicated analysts.

Salt Spray Tester

01Salt Spray Tester

Neutral salt spray testing per ASTM B117, ISO 9227, and DIN 50021 simulates harsh corrosive conditions to verify the white- and red-rust resistance hours of coatings and sealers, ensuring fasteners meet customer and OEM corrosion specifications.

Atomic Absorption Spectrometer

02Atomic Absorption Spectrometer

Precisely measures metal concentrations in plating baths to keep chemistry in the optimal range — the key instrument for controlling nickel content in Zinc-Nickel alloys.

Titration Testing

03Titration Testing

Routine titration analysis of bath chemistry with immediate adjustment keeps the process stable and batches consistent.

X-Ray Coating Thickness Measurement

04X-Ray Coating Thickness Measurement

Non-destructive coating thickness measurement, quickly verifying each batch against customer and OEM thickness specifications.

Friction Coefficient Tester

05Friction Coefficient Tester

Measures tightening torque and clamp load simultaneously per ISO 16047 and related standards to calculate thread and bearing-face friction coefficients, verifying the torque–tension behavior of coatings and lubricated sealers so customers achieve consistent tightening on the assembly line.

Automatic Titrator

06Automatic Titrator

An automatic titration system with a sample changer analyzes multiple plating-bath samples in sequence, dosing reagents and detecting endpoints automatically — reducing manual reading error and keeping bath chemistry data timely and consistent between batches.
