What are the effects of production process on the temperature resistance of vehicle silicone hose

In today's rapidly developing automobile industry, vehicle silicone hose is an important part of key components such as cooling system, fuel system and turbocharging system. Its quality and performance have a direct impact on the overall operating effect of the car. Therefore, the production process has become one of the key factors that determine the quality of silicone tubes, especially in terms of temperature resistance, and its impact is particularly far-reaching.

Material selection and proportioning
The selection and proportion of materials are the basis of the silicone tube production process. Our company adheres to high standards and selects high-quality silicone materials. These materials not only have excellent high and low temperature resistance, but also show good corrosion resistance and elasticity. In terms of material ratio, according to the specific use environment and performance requirements of the silicone tube, we scientifically adjust the ratio of various raw materials to achieve the best temperature resistance effect. For example, by introducing functional groups such as phenyl, trifluoropropyl and cyano groups, the temperature resistance and oil resistance of silicone are significantly improved, thereby enhancing the overall temperature resistance of the silicone tube.

Mixing and vulcanization process
The mixing process is a key step in uniformly mixing silicone raw materials with various additives (such as reinforcing agents, vulcanizing agents, structure control agents, etc.). Our company uses advanced mixing equipment and technology to ensure precise control of parameters such as temperature, pressure and time during the mixing process to ensure the uniformity and stability of the mixed rubber. The vulcanization process is to cross-link the mixed rubber material under high temperature and high pressure conditions to form a stable three-dimensional network structure. We adopt advanced vulcanization processes such as two-stage vulcanization technology. By precisely controlling vulcanization temperature, time and pressure, we ensure that the silicone tube forms a dense cross-linked structure during the vulcanization process, thereby significantly improving its temperature resistance.

Extrusion and molding processes
The extrusion process is the process of processing the mixed rubber material into shape through an extruder. Our company is equipped with sophisticated extrusion equipment and molds to ensure that the silicone tube has uniform wall thickness and smooth surface during the extrusion process. In addition, we strictly control parameters such as extrusion temperature and speed to prevent the rubber material from overheating or uneven cooling during the extrusion process, which will affect the temperature resistance of the silicone tube. The molding process is to shape the extruded silicone tube. We use advanced molding technologies and equipment such as vacuum shaping and water cooling shaping to ensure that the silicone tube maintains a stable shape and size during the molding process.

Post-processing and inspection
Post-processing is the stage of further processing and processing of silicone tubes, including trimming, grinding, cleaning and other processes. Our company uses professional post-processing equipment and processes to ensure that the silicone tube is not damaged or contaminated during the process. At the same time, we strictly monitor the temperature and time during post-processing to avoid adverse effects on the temperature resistance of the silicone tubes. The inspection link is to detect and evaluate the performance of the silicone tube. We use advanced testing equipment and methods, such as thermal aging tests and high-temperature impact tests, to comprehensively evaluate the temperature resistance of silicone tubes to ensure that they meet industry standards and customer needs.
