We carefully select high-quality aluminum rods and molds, adopting advanced manufacturing processes such as precision mold nitrogen extrusion and mold blasting. Our products maintain a stable precision of 0.03mm, Exceeding the national standard of ultra-high precision level.
Using high-quality 6005N aluminum rods and the T6 heat treatment process, which includes water quenching, a 24-meter cold bed, and strong air cooling, the tensile strength of the extruded profiles reaches 267Mpa, with an average Vickers hardness of 15HW. The surface hardness of the profiles is further increased after shot blasting. The 6005N alloy material has high tensile strength and is not prone to fracturing, effectively meeting various harsh usage scenarios (such as deserts, industrial and commercial rooftops, and wild fish ponds, etc.). In contrast, the 6063-T5 products on the market have a tensile strength of about 180Mpa and an average Vickers hardness of only 10HW. The tensile strength of Huicheng's products is 1.5 times that of the common products on the market.
Adopting the sandblasting oxidation process. High-speed compressed air sprays steel grit on the surface of the aluminum profile, resulting in tiny depressions on the product surface. The depressions are uniform and fine, with a gentle appearance, elegant color, and a uniform metallic matte texture. The oxidized product has a warm luster and a delicate touch.
The thickness, quality, and sealing quality of the oxide film determine whether the product meets the national standard requirements for corrosion resistance and aging resistance, and also determine whether the product can reach the standard for a service life of 25 years.
1、Strictly select pure water production process to ensure the stability of the chemical composition and quality of the liquid.
2、Use refrigeration porcess with ice machines to control the process temperature of each oxidation tank within the optimal range, ensuring that the oxide film is hard, has a high porosity, and has excellent performance.
3、Adopt medium-temperature sealing process to ensure good sealing quality and avoid environmental hazards caused by the use of heavy metals.
4、Ensure product quality stability through management measures such as regular chemical testing of the bath liquid by the laboratory, regular quality inspections by the quality control department, and regular detection of process parameters by operators.
5、 By implementing a drying process on the finished product after oxidation, the quality of the sealing process is enhanced, and defects such as surface scratches and abrasions, which may occur due to lack of drying, are avoided.
