Required proof	Identity, Ca content/phase where relevant, formulation, laser matrix, contrast, damage, durability, and documents	Exact identity, formulation, laser matrix, contrast, damage, durability, and documents	Exact identity, formulation, laser matrix, contrast, damage, durability, and documents

Optical blackness remains separate supporting context. A low-reflectance result at one spectrum, film construction, roughness, or gloss condition is not a laser-marking ranking.

Stabilitas

Use the same initial conditioning, abrasion, cleaning, chemical, humidity, weathering, or thermal-aging exposure, recovery time, and post-aging readout for every candidate. Report contrast or code grade together with surface and mechanical integrity.

Kemampuan proses

Record grade identity, supplied form, surface treatment where known, loading, dispersion route, polymer, color package, molding or coating history, part thickness, wavelength, focus, speed, power, pulse condition, and surface finish. Compare only candidates that can be processed without unstable agglomeration or unacceptable base-part appearance.

Posisi biaya

Compare delivered functional cost at the accepted loading and yield, including dispersion, cycle time, scrap, rework, qualification, documentation, and supply continuity. Do not rank the candidates from powder price alone.

Kasus penggunaan umum

A dark visual laser mark in a polymer part where these three inorganic routes are being screened under one controlled design of experiments. For light marks, LDS/MID plating, or light/transparent-host constraints, return to the mechanism selector before using this matrix.

Required Proof

Release evidence should include the exact material identity, polymer and color package, loading, part geometry, wavelength and optics, laser-setting matrix, contrast/readability method, damage boundary, process-window result, durability result, and current TDS/SDS state.
