Quality Control
Our Spray Surface Treatment service is supported by a rigorous Quality Control (QC) process to ensure consistent coating performance, durability, and visual quality across every production batch.
Incoming Material Inspection
All base metals are verified for alloy composition, surface integrity, and cleanliness prior to spray coating.
Surface pre-treatment (e.g., degreasing, sandblasting, or chemical etching) is inspected to ensure optimal coating adhesion.
In-Process Quality Checks
Spray parameters (e.g., gun pressure, distance, spray angle, and environment conditions) are monitored and controlled in real time.
Cure cycle parameters (oven temperature, time) are validated to ensure complete cross-linking of coating materials.
Cleanroom or dust-controlled environments used where required to prevent contamination of coated surfaces.
Post-Treatment Inspection
Adhesion testing (ASTM D3359 – Cross Hatch or Pull-Off Test)
Coating thickness verification (ASTM D7091 using magnetic or eddy current gauges)
Color matching and gloss level verification per customer or Pantone specification
Salt spray corrosion test (ASTM B117) on representative samples for durability assessment
Surface appearance check for uniformity, defects (e.g., runs, orange peel, pinholes)
Documentation & Traceability
Full batch traceability with coating parameters, inspection logs, and material lot records
Certificates of Conformance (CoC) provided upon request
Process complies with ISO 9001:2015 and relevant coating standards (e.g., ISO 12944, ASTM standards)
Continuous Improvement
QC team collaborates with production and R&D to:
Implement lean and Six Sigma practices
Reduce coating defects and rework
Improve coating performance based on feedback, testing, and benchmarking
FAQ
1. What materials are suitable for spray surface treatment?
Answer:
Spray coating can be applied to a wide range of metals, including aluminum, magnesium, titanium, zinc alloys, and steel. Proper surface preparation (e.g., cleaning, degreasing, blasting) is essential to ensure adhesion and coating performance.
2. What types of coatings are available?
Answer:
We offer various types of spray coatings including:
Epoxy – Excellent chemical resistance and adhesion
Polyurethane – UV-resistant and flexible
Fluoropolymer (e.g., PTFE-based) – Non-stick and corrosion-resistant
Powder Coating – Durable, environmentally friendly, with a wide color range
3. How is coating thickness controlled and measured?
Answer:
Coating thickness is controlled by adjusting spray parameters and monitored using non-destructive gauges, in accordance with ASTM D7091. Typical thicknesses range from 30–150 µm, depending on the application.
4. What is the typical turnaround time for spray surface treatment?
Answer:
Standard turnaround time is 5–7 working days, depending on part complexity, coating type, and batch size. Expedited services may be available upon request.
5. How durable are spray coatings in terms of corrosion and wear resistance?
Answer:
Durability depends on the coating system used. Properly applied coatings can achieve:
≥ 336 hours salt spray resistance (ASTM B117)
Good impact and abrasion resistance
Temperature tolerance up to 200°C
For enhanced protection, multi-layer primer/topcoat systems can be used.
