READ MOREIn the production process of pipeline rubber seals, effectively preventing the generation of bubbles and impurities is a key link to ensure the sealing performance and appearance quality of the product. This process requires not only a high degree of process control and technical precision, but also advanced testing equipment and a strict quality management system as support. Combined with our company's rich experience and advanced technology in the field of rubber seal production, the following will discuss in detail how to effectively prevent the generation of bubbles and impurities in the production process.
The quality of raw materials is the basis for preventing the generation of bubbles and impurities. Our company uses high-quality rubber materials, including but not limited to nitrile rubber, silicone rubber, fluororubber, EPDM rubber, natural rubber, chloroprene rubber, hydrogenated nitrile rubber, butyl rubber and polyurethane rubber. These materials have their own characteristics, such as high temperature resistance, high pressure resistance, corrosion resistance, wear resistance, low temperature resistance and food grade, which can meet the needs of different pipeline systems.
In the pretreatment stage of raw materials, we strictly control the storage environment and time of raw materials to avoid moisture, contamination or aging of materials. For compound rubber, we use high-precision compounding equipment to ensure that rubber and additives (such as plasticizers, fillers, vulcanizers, etc.) are evenly mixed to reduce the chance of impurities being mixed in. At the same time, the compound rubber is strictly filtered and degassed to remove tiny particles and gases in it.
During the molding process, mold design and cleaning are crucial. Our company uses precision-machined molds to ensure that the mold surface is smooth and flawless to reduce the possibility of bubbles when the rubber is injected into the mold. Before each use of the mold, we will perform strict cleaning and lubrication to avoid residual impurities inside the mold.
During the injection molding process, we strictly control the injection pressure and speed, as well as the mold temperature. Reasonable injection pressure and speed can ensure that the rubber fills the mold evenly and quickly, reducing the formation of bubbles. At the same time, the appropriate mold temperature helps the flow and vulcanization of the rubber, further reducing the generation of bubbles and impurities.
Vulcanization is a key step in the production of rubber seals, which directly affects the physical properties and appearance quality of the product. We use advanced vulcanization equipment and processes to accurately control the vulcanization temperature, time and pressure to ensure that the rubber is fully vulcanized and reduce the bubbles generated during the vulcanization process.
After vulcanization, we carry out strict post-processing, including deburring, cleaning and surface treatment. These steps not only help to improve the appearance quality of the product, but also further remove possible residual impurities and tiny bubbles.
To ensure the sealing performance and appearance quality of the final product, our company has advanced and complete top-notch testing equipment in the industry. These equipment include but are not limited to analytical balance, electronic tensile testing machine, aging test chamber, micro melting point meter, rubber and plastic density meter, projector (two-dimensional), Mooney viscometer, hardness tester, closed rotorless vulcanizer, thickness gauge, electronic balance, Phoenix size detection equipment, double-turn rotary oil seal test machine, glass disc screening machine, hot air aging test chamber, liquid density meter, flaw detector, oil seal radial force tester and high temperature creep stress relaxation tester.
Through these equipment, we can conduct comprehensive testing of various performance indicators of rubber seals, including tensile strength, elongation at break, hardness, density, degree of vulcanization, aging resistance, wear resistance, etc. Especially for the problem of bubbles and impurities, we can use equipment such as flaw detectors and high-power projectors to conduct detailed inspections of the products to ensure that the final products are free of bubbles and impurities and meet the strict requirements of customers.
Our company has established a complete quality management system, from raw material procurement, production process control to finished product inspection, every link has formulated strict standards and processes. At the same time, we focus on continuous improvement, and through data analysis, customer feedback and technological innovation, we continuously optimize production processes and quality control methods to ensure that product quality always remains at the leading level in the industry.
Through strict raw material selection, optimized molding process, precise vulcanization and post-processing, advanced testing equipment and a complete quality management system, our company can effectively prevent the generation of bubbles and impurities in the production process of pipe rubber seals, ensuring the sealing performance and appearance quality of the products. Our technical advantages and quality commitment provide customers with reliable, safe and efficient rubber seal solutions.
