A silicone extruder is a rubber-processing machine used in tire manufacturing. The extrusion‑molding process employed by such machines is quite complex: at a specific low temperature, the extrusion method causes the silicone to dissolve; the resulting viscous mass is then forced through the die of the extruder head to form the desired shape according to process specifications. This is a highly demanding operation that requires meticulous pre‑operation checks on the extruder and calls for operators with extensive experience—only the seamless integration of technical expertise and practical know-how can ensure the flawless execution of this process. The key technical aspects of this silicone extrusion‑molding technique are as follows:
The silicone extruder is a rubber-processing machine used in tire manufacturing. The extrusion‑molding process itself is quite complex: at a specific low temperature, the extrusion method employed during tire production causes the silicone to dissolve; the resulting viscous mass is then forced through the die opening of the die head to form the desired shape required by the process. This is a highly demanding operation that necessitates a thorough pre‑operational inspection of the silicone extruder and requires operators with extensive experience. Only the seamless integration of technical expertise and practical know‑how can ensure the flawless execution of this process.
The aforementioned extrusion‑molding method using a silicone‑rubber extruder has relatively high technical requirements; however, it is highly efficient and can help reduce production costs, making it well suited for widespread adoption across the industry.
In addition, during the production of silicone rubber extruders, it is important to apply pressure at the feed inlet to ensure stable product output. Therefore, effective temperature‑control methods should be employed; using a mold‑temperature controller for cooling is an excellent approach. Furthermore, since no vulcanization has been carried out, the molded rubber remains relatively soft, necessitating subsequent passage through a vulcanization oven for complete curing.
