Durable PTFE Coatings for Industrial Applications | Enhance Equipment Lifespan

At Jimo Qiyuanhangxing Mould Processing Factory, we employ advanced and reliable methods to apply our Teflon coatings, ensuring optimal performance and durability. The first crucial step in the application process is surface preparation. We start by sandblasting the substrate, whether it's metal, ceramic, or plastic. Sandblasting involves using high - pressure air to propel abrasive particles onto the surface, creating a rough texture. This roughened surface provides a better grip for the Teflon coating, enhancing adhesion. However, we recognize that sandblasting alone may result in a relatively weak bond in some cases. To address this, we often use a resin - based bonding agent. The resin acts as an intermediary between the substrate and the Teflon coating, strengthening the connection and ensuring long - lasting performance. After surface preparation, we have two main methods for applying the Teflon coating: conventional spraying and electrostatic spraying. Conventional spraying is a widely used technique. We load the Teflon coating material, which can be in liquid or powder form, into a spray gun. The spray gun is then held perpendicular to the surface, and the coating is applied in a series of rectangular motions. This method is highly versatile and is suitable for a wide range of substrates, including those with complex shapes or irregular surfaces. It allows for precise control over the coating thickness, ensuring a uniform finish. For example, in coating kitchen utensils with complex contours, conventional spraying can be adjusted to coat every nook and cranny evenly. Electrostatic spraying, on the other hand, is more efficient for large - scale applications or when a thicker, more uniform coating is required. In this method, the spray gun is modified to give the Teflon particles a negative charge. The substrate is grounded, creating an electrostatic attraction between the charged particles and the substrate. This results in better adhesion and more even coverage, as the charged particles are attracted to all parts of the substrate, including hard - to - reach areas. It also reduces overspray, minimizing waste and ensuring a more cost - effective process. Once the coating is applied, it undergoes a curing process. Curing typically involves heating the coated object in an oven at a specific temperature for a set period. This process helps the Teflon coating to fully develop its non - stick, heat - resistant, and chemical - resistant properties, ensuring that the final product meets our high - quality standards.
