The 2.80 valve core series, as a core component suitable for faucets and other fluid control devices, covers two major types of materials: plastic and metal, designed to meet the functional requirements of different application scenarios. The plastic valve core is made of high-quality polymer materials and manufactured through precision manufacturing processes. It has the characteristics of low cost, lightweight, high strength, strong corrosion resistance, and good sealing performance, ensuring stable and efficient control of water flow. At the same time, it meets environmental standards and has minimal impact on water quality. In contrast, metal valve cores, especially those made of stainless steel, have become the preferred choice for pursuing higher performance requirements due to their high strength, wear resistance, and long lifespan characteristics. This type of valve core utilizes advanced laser cutting technology to achieve precise hole opening, ensuring uniform distribution of water flow and precise temperature regulation, making it suitable for high-end applications with strict requirements for fluid control accuracy.

View MoreSurface treatment of 2.80 one-inch metal valve stem
In the production process of metal valve stems, especially one-inch stainless steel valve stems, Shanghai Quntong Spray Packing Material Co., Ltd. uses multiple surface treatment technologies to enhance its corrosion resistance and improve its overall aesthetics. These treatments include but are not limited to advanced processes such as polishing, electroplating and spraying.
Polishing: Polishing is one of the key steps in metal surface treatment. It can not only remove tiny flaws on the metal surface, but also make the metal surface achieve a mirror effect, significantly improving the visual beauty of the product. Shanghai Quntong uses advanced mechanical polishing and chemical polishing technology to ensure that every inch of the metal valve stem surface is as smooth as a mirror, which not only enhances corrosion resistance, but also gives the product a high-end texture.
Electroplating: In order to further enhance the corrosion resistance of stainless steel valve stems, the company applies professional electroplating technology. Through electroplating, a dense protective layer can be formed on the metal surface. This protective layer can not only effectively isolate the external environment from erosion of the substrate, but also adjust the composition of the coating as needed to achieve specific anti-corrosion, wear-resistant or decorative effects. Shanghai Quntong has rich experience in electroplating and can accurately control the thickness and uniformity of the electroplating layer to ensure that each batch of products can achieve optimal performance.
Spraying treatment: For metal valve stems in specific application scenarios, the company may also use high-quality spraying technology, such as powder spraying or liquid spraying, to provide an additional protective layer or achieve a specific color effect. These spraying materials usually have good weather resistance, chemical resistance and decorative properties, and can give it a more diverse appearance without affecting the function of the valve stem.
Pretreatment of 2.80 plastic one-inch valve stems
For plastic valve stems, especially 2.80 plastic one-inch valve stems used in fluid control devices such as faucets, pretreatment before production is also crucial. Shanghai Quntong Spray Packing Material Co., Ltd. also demonstrated its technical strength and extreme pursuit of details in this link.
Drying treatment: If the plastic material contains too much moisture before production, it will affect the molding quality and the performance of the final product. Therefore, before producing plastic valve stems, Shanghai Quntong will strictly dry the raw materials to ensure that the moisture content in the plastic particles is controlled at an extremely low level. This not only helps to improve the dimensional stability and mechanical strength of the product, but also reduces bubbles and warping during the molding process, ensuring the precision and durability of the valve stem.
Heating treatment: Heating pretreatment is an important step in plastic processing. It helps soften and flow plastic materials, facilitating subsequent injection molding. Shanghai Quntong uses advanced temperature control equipment to accurately control the preheating temperature and time of plastic particles to ensure that the plastic reaches the best plastic state before injection molding, thereby improving the molding accuracy and surface quality of the valve stem. In addition, reasonable heating treatment can effectively reduce the internal stress during the injection molding process and enhance the crack resistance and fatigue resistance of the valve stem.
Through the above pretreatment steps, Shanghai Quntong Spray Packing Material Co., Ltd. ensures that the 2.80 plastic one-inch valve stem has good processing performance and the physical properties required for the final product before production. This not only improves the overall quality of the product, but also lays a solid foundation for subsequent molding processing and optimization of product performance.
