1. ** Mixing ** : Add raw rubber, reinforcing agents, vulcanizing agents and other compounding agents to the mixing equipment in accordance with the formula ratio, and thoroughly mix them evenly to form a mixed rubber with certain plasticity and processing performance.
2. ** Extrusion molding ** : By using an extruder, the mixed rubber compound is extruded through a die of a specific shape to form the required tubular shape. During the extrusion process, it is necessary to control the temperature, pressure and extrusion speed well to ensure the dimensional accuracy and appearance quality of the silicone tube.
3. ** vulcanization ** : The extruded silicone tubes need to undergo vulcanization treatment to cause cross-linking reactions in the rubber compound, thereby enhancing the physical properties and chemical stability of the silicone tubes. Common vulcanization methods include hot air vulcanization and steam vulcanization, etc.
4. ** Post-treatment ** : The vulcanized silicone tubes may require some post-treatment, such as cutting, grinding, and printing labels, to meet different usage requirements.
5. ** Inspection and Packaging ** : Inspect the processed silicone tubes in terms of appearance, size, performance, etc. After passing the inspection, they will be packaged and stored in the warehouse
