Quality Assurance
Our Quality Assurance (QA) process ensures the highest standards for spray surface treatment. Here's a summary of key QA practices:
Material Inspection: Incoming materials are checked for alloy composition, cleanliness, and surface integrity.
In-Process Monitoring: Coating thickness, adhesion, and application conditions (e.g., temperature, humidity) are closely monitored in real-time to ensure consistency.
Post-Treatment Testing: Adhesion, coating hardness, and corrosion resistance are verified using standard tests (e.g., ASTM D3359, B117).
Final Inspection: Parts are checked for dimensions, surface finish, gloss, and defects before delivery.
Documentation: Full batch traceability, Certificates of Conformance (CoC), and inspection reports are provided.
Continuous Improvement: Customer feedback and root cause analysis drive ongoing process enhancements.
Our QA program follows ISO 9001:2015 standards, ensuring reliable, high-quality spray coatings for all applications.

FAQ
1. What is Spray Surface Treatment?
Spray Surface Treatment is a finishing process where a protective coating is applied to metal surfaces using spray techniques. It improves the durability, aesthetics, and corrosion resistance of CNC-machined parts, with options for various coating types like epoxy, polyurethane, and powder coating.
2. Which metals can be treated with this service?
This service is typically used for aluminum, stainless steel, titanium, magnesium, and zinc alloys. It’s suitable for a wide range of industries, including aerospace, automotive, and electronics.
3. How long does the coating last?
The longevity of the coating depends on factors such as the type of coating, environmental exposure, and maintenance. With proper care, the treatment can last between 5 to 20 years, offering high resistance to wear, corrosion, and environmental damage.
4. Can I choose the color or finish for my parts?
Yes, we offer a variety of color options, including custom Pantone shades, and different surface finishes like matte, satin, glossy, and textured. This flexibility ensures that the treatment meets both functional and aesthetic requirements.
5. Is the process environmentally friendly?
Yes, our spray surface treatment process is environmentally conscious. We use RoHS and REACH compliant coatings, low-VOC spray systems, and adhere to responsible chemical waste management practices to minimize environmental impact.
