The unique design of the silicone tube extruder, combined with its advanced feeding system, enhances production stability and reduces reliance on manual labor. With a high compression ratio and an extended length-to-diameter ratio, the screw ensures superior extrusion density and mixing performance, resulting in products with smooth inner and outer surfaces, no air bubbles, and consistent dimensional stability. Performance Features of the Silicone Tube Extruder 1. This machine is equipped with an AC motor featuring variable-frequency speed control, offering a wide speed range and excellent adaptability to producing silicone rubber products of different specifications, while ensuring convenient operation. 2. It utilizes a specialized reducer designed specifically for hard-toothed-surface rubber extruders, providing low noise levels, high transmission torque, reliable and smooth operation, and easy maintenance. 3. Equipped with pneumatic cylinder forced feeding, this extruder can process multi-layer rubber strips, achieving dense extrusion and superior product quality. 4. A dual-channel automatic temperature controller is installed, minimizing temperature fluctuations during heating. It allows for optimal selection of heating temperatures based on specific processing requirements and automatically regulates the set temperatures of both the barrel and die. 5. The machine employs electric heating for the barrel and circulating cooling, enabling prompt and reliable cooling of materials to prevent thermal degradation. Operation and Maintenance of Silicone Tube Equipment 1. Before use, the hard-toothed-surface reducer must be lubricated according to the oil level indicator—use gear oil in summer and No. 45 mechanical oil in winter. Regular replacement of the lubricant will extend the reducer’s service life. 2. Prior to starting the silicone tube extruder, verify that the power supply is secure to prevent motor damage or burnout caused by poor electrical contact. 3. Before using the vacuum head, tighten all screws and fasteners; after shutdown, thoroughly clean out any remaining material. Once powered on, adjust the core properly. 4. Before operating the barrel and screw, check whether any metal fragments have entered the silicone material to avoid damaging the equipment. Before stopping, ensure all material has been completely extruded from the barrel and screw to prevent residual cured material from affecting subsequent operations. 5. (1) Clean the gearbox oil tank and inspect gear meshing for wear; adjust belt tension appropriately, and regularly apply wheel lubricant. (2) Remove any cured material from the barrel and screw interior to prevent leakage and ensure unobstructed water flow within the machine’s water jacket. (3) Periodically inspect bearings and rotating shafts in the vulcanization chamber for signs of wear or looseness, determining if component replacements are necessary. Also, examine the heating and sealing systems, replacing or adding heating elements as needed, and clean ventilation ducts to maintain proper airflow.

The entire unit is equipped with vibration-damping feet. During installation, ensure proper layout and sufficient operating space. Equipment Operating Instructions Before conducting a trial run, carefully inspect the following items: 1. Verify that the local power supply parameters match those specified in this manual, and confirm that all electrical components are correctly and securely connected. 2. Check all connections for looseness; if any are loose, tighten them promptly. 3. Confirm that the gearbox contains the correct lubricant and that the oil level is adequate. Use medium‑pressure gear oil N150 or another high‑quality gear oil of similar viscosity. The oil level should reach the upper mark on the gearbox’s oil dipstick. 4. Manually rotate the coupling connecting the main motor to the gearbox in a clockwise direction for at least two full revolutions. The rotation should be smooth and effortless. 5. Ensure the main motor rotates in the correct direction: when viewed from the head end, it should turn clockwise. After completing these checks, proceed with the trial run of the main unit. The key steps are as follows: 1. Increase the temperature of the main unit; the specific temperature varies depending on the material being processed and should be set by the user. Once the desired temperature is reached, maintain it for 0.5–1 hour. Monitor the temperature control system during heating to ensure proper operation. 2. Verify that the cooling water system is functioning normally and check for leaks. If any leaks are detected, address them immediately. 3. After completing all the above steps, begin rotating the screw. Do not feed material yet; gradually increase the screw speed to approximately 40 r/min and run the machine idling for about 4–5 minutes. Observe whether the equipment operates smoothly. If any abnormalities occur, stop the machine immediately, rectify the issue, and then restart. Gradually increase both the screw speed and the feed rate until the desired production capacity is achieved.

Meanwhile, specialized manufacturing allows for fixed-location production or even global sourcing of individual system modules and components, which greatly benefits overall quality assurance, cost reduction, and accelerated capital turnover. High Efficiency and Multifunctionality The high efficiency of plastic extruders is primarily reflected in their high output, low energy consumption, and reduced manufacturing costs. Functionally, screw-type plastic extruders are no longer limited to polymer material extrusion and compounding; their applications have expanded into fields such as food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics, and more. Large-Scale and Precision Manufacturing Scaling up plastic extruders helps reduce production costs, with particularly clear advantages seen in large twin-screw pelletizing units, blown-film lines, and pipe-extrusion systems. Major technological equipment required for key national projects—such as the large-scale extrusion pelletizing unit that serves as one of the three critical pieces of equipment supporting major ethylene projects—has long relied on imports. Therefore, accelerating domestic production is essential to meet the needs of the petrochemical industry. Intelligent and Networked Operation In developed countries, plastic extruders commonly employ modern electronic and computer control technologies to monitor process parameters online—including melt pressure and temperature, barrel temperatures at various sections, speeds of the main and feeding screws, feed rates, raw material ratios, and motor current and voltage—and implement microcomputer-based closed-loop control. This approach significantly enhances process stability and improves product precision.
