Introduction to Peening and Powder Coating Process of Yizhan International Trading Co., Ltd.
The peening and powder coating process, an advanced surface treatment technology that combines peening pre - treatment and powder coating, plays a crucial role in enhancing the comprehensive performance of metal products. Yizhan International Trading Co., Ltd. leverages this process to commit to creating metal products for customers that feature high corrosion resistance, excellent wear resistance, and attractive decorative properties.
Peening Process
Principle
Yizhan International Trading Co., Ltd. utilizes advanced peening equipment. Inside the equipment, a high - speed rotating impeller projects pellets (such as high - quality steel pellets, cast iron pellets, etc.) onto the surface of metal workpieces at extremely high speeds. During this process, the powerful impact and friction of the pellets can efficiently remove various impurities on the workpiece surface, including rust, scale, and oil stains. At the same time, the surface of the workpiece generates a specific compressive stress due to the impact of the pellets. This not only significantly improves the fatigue strength of the workpiece but also greatly enhances its resistance to stress corrosion.
Function
After peening treatment, the metal surface forms an appropriate roughness, providing a more secure attachment foundation for the subsequent powder coating. This significantly increases the adhesion between the coating and the workpiece surface. Moreover, the peening treatment makes the surface more uniform and flat, ensuring that the powder coating can be evenly applied. This effectively guarantees the quality and protective performance of the coating, laying a solid foundation for the long - term and stable use of the product.
Powder Coating Process
The powder coating process is consistent with the industry - standard powder coating process. Plastic powder is evenly sprayed onto the surface of workpieces that have undergone peening pre - treatment and meet the surface condition standards. Subsequently, through precise control of the heating and curing process, the plastic powder is transformed into a durable plastic coating, perfectly achieving the dual goals of protecting and decorating the workpiece.
Process Flow
Peening Pre - treatment
When operating, Yizhan International Trading Co., Ltd. accurately places the workpieces on the professional workbench of the peening equipment. After starting the equipment, the pellets are projected onto the surface of the workpieces at high speeds for treatment. Based on the material characteristics of the workpieces, their initial surface conditions, and specific treatment requirements, the company's professional technicians precisely adjust key parameters such as peening intensity, treatment time, and pellet size to ensure that the impurities on the workpiece surface are completely removed and the required roughness and cleanliness standards are accurately achieved. After the treatment is completed, advanced vibrating screens or high - power vacuum cleaners and other equipment are used to quickly and thoroughly remove the remaining pellets and impurities on the workpiece surface.
Powder Coating
Powder coating operations are carried out on the peened workpieces. The specific process includes pre - treatment procedures (such as fine degreasing, phosphating, etc., to further strengthen the coating adhesion), accurate spraying of plastic powder, and scientific curing. These steps are strictly consistent with the standard process of the conventional powder coating process in the industry. Through this series of rigorous procedures, a high - performance powder coating is successfully formed on the surface of the workpieces. All the equipment owned by Yizhan International Trading Co., Ltd. adopts the advanced peening and powder coating process, ensuring that each product can meet high - quality standards.
