Guideline of surface treatment
Through rigorous testing and certified processes, we ensure every product meets the highest industry standards
In industrial applications, surface treatment refers to the modification of material surfaces—particularly metals and plastics—using controlled physical, chemical, or electrochemical techniques. This process has gained significant attention in recent years, serving both functional and aesthetic purposes.。
The treatment is more than coating; it re-engineers the surface itself at the chemical, microstructural, and physical levels, and may even adjust its macro geometry. The result is performance advantages absent or underdeveloped in the base material.
Surface treatment is very important to improve the functional properties and appearance of castings. Prime offers a variety of customized processing solutions, each of which has been precisely designed to meet the standards and application requirements of different industries. With a wealth of professional experience, we ensure that your castings not only have excellent appearance, but also in the actual working conditions to achieve reliable and lasting performance

How to Select the Best Finish for Your Product
Material Composition & Application Fit
Anodizing is the preferred finish for aluminum, whereas steel is compatible with numerous plating and surface treatments. Our team evaluates hardness, conductivity, and chemical/physical integrity prior to recommending the most suitable option.
Service Environment & Functionality
Corrosive settings—such as moisture, salt mist, or chemical contact—are best addressed with zinc coatings, passivation, PTFE, or PVD treatments. For harsh mechanical loads like heat, pressure, or abrasion, DLC, hard chrome, or PVD are suitable solutions. For electrical components, finishes must be tailored to either maintain conductivity or provide insulation.
Economic Efficiency & Budget Alignment
Finishing methods, whether economical polishing or premium vacuum PVD, come with varying costs. We focus on aligning performance needs with budget targets to deliver the greatest ROI, especially in volume manufacturing.
Regulatory Compliance & Eco-Sustainability
We prioritize solutions aligned with global regulations (e.g., VOC limits, hazardous substance control). Powder coating and PVD are greener options versus some legacy chemistries.。
Part Size, Form & Production Volume
Uniform coating can be difficult to achieve on complex internal features with traditional plating or painting. Alternatives such as chemical conversion or PVD are often more effective. In high-volume production, automation helps control costs and ensures repeatable quality.
