Reliable corrosion protection is critical for components operating in demanding environments. At Alpha Manufacturing, durability is considered from the earliest stages of production, ensuring components are supplied with coatings designed to perform long after installation.
By working with advanced powder coating and pre-treatment processes capable of achieving 1,000 hours of salt spray corrosion resistance, Alpha Manufacturing offers customers confidence that their components will withstand harsh operating conditions while maintaining long-term integrity.
Salt spray testing simulates prolonged environmental exposure through continuous saline spray. To meet the 1,000-hour benchmark, corrosion must not exceed 2mm from the scribed area, making it a widely recognised industry standard for long-term performance.
Advanced Pre-Treatment for Long-Term Performance
The foundation of effective corrosion resistance lies in correct surface preparation. Alpha Manufacturing incorporates modern Oxsilan-based pre-treatment technology as part of its coating capability, offering a state-of-the-art alternative to traditional zinc or phosphate systems.
By combining zirconium and silane chemistry, this process forms an ultra-thin protective layer that delivers corrosion resistance comparable to much thicker zinc-phosphate coatings with greater efficiency and reduced environmental impact.
Controlled Processes, Consistent Results
The pre-treatment process follows a tightly controlled, multi-stage system including alkaline cleaning, rinsing with demineralised water, application of Oxsilan pre-paint treatment, and final rinsing prior to coating. This structured approach ensures optimal adhesion, enhanced durability, and consistent results across repeat production.
Process integrity is maintained through daily internal testing, Statistical Process Control (SPC), and regular external verification by Chemetall, the developer of Oxsilan technology. This
ensures quality is monitored proactively at every stage.
Added Value for Alpha Manufacturing Customers
Correct pre-treatment delivers stronger adhesion, extended service life, reduced maintenance requirements, and greater reliability in finished components. As customer specifications increasingly demand 1,000 hours of corrosion resistance, Alpha Manufacturing provides a proven, dependable solution.
By integrating advanced corrosion protection, rigorous quality control, and sustainable processes into its service offering, Alpha Manufacturing adds measurable durability and long-term value to every coated component it supplies.
