Surface Coating Process Guidelines
1, Surface Preparation Requirements
PVD Coating:
Requires Class-A surface finishing (Ra ≤ 0.2μm per ISO 1302)
Demands precise tooling marks alignment (≤0.05mm deviation)
Powder Coating:
Tolerates surface roughness up to Ra 3.2μm (ASME B46.1)
Sandblasting at 80-100 grit suffices for adhesion enhancement
Surface Coating Process Specifications
1. Stain Resistance Performance
PVD Coating:
Shows fingerprint susceptibility (＞85% visible mark retention rate in ASTM F1319 testing)
PVD + Lacquer Composite:
Achieves fingerprint-resistant certification (ISO 4618 Class B standards) through nano-scale surface encapsulation

Overview of PCS product classification
Overview of PCS product classification-There are about 211 models of the design, with 33 models of independent R&D. The economy models are 679 in total.
Our products are divided into 4 categories according to different applications, Handle, lock, hinge and Door accessories. Each category is subdivided according to the market habits to make it easier for customers to search.
‘Recommended models’ are categorised according to their original purpose and according to the market need they address. Take Lever handle as an example:
