From aluminum profile recycling to cold drawing, honing, aging, polishing, sandblasting, CNC lathing, and hard anodized, we conduct strict product testing in each process to ensure that the products are qualified and leave the factory, For the past 16 years, our company has had very strict quality requirements for our products. Compared to the same product on the market, our products have more stringent requirements for product technology in the production and processing process, meeting customers' various requirements for high precision, durability, and low energy consumption. We require the cylinder barrels to meet the following indicators: 1. Inner roughness < 0.25 um (grinding) without apparent porosity, surface defects such as scratches or cracks 2. Can work under 8 bar pressure cylinder 3. Cylinder work of heat resistance can reach 600 degrees 4. The service life can reach 13000 ~ 15000 hours 5. Anodized layer thickness above 25 um 6. The anodized hardness HV420. The above indicators are far higher than the industry standard requirements. We have always believed that only high requirements can produce high-quality products, which is our responsibility to customers and also to the development of the factory.For many years, our polishing of our products has been similar to Foshan's research on kung fu, striving to create the "Foshan Cylinder - Weiyingsi Brand".
