It is suitable for producing pipes made from materials such as PP, PE, PS, ABS, PVC, PPC, and other resins. The barrel and screw are specially designed to ensure efficient extrusion and excellent plasticization. Analysis of Plastic Pipe Production Lines: As an important component of chemical building materials, plastic pipes have been widely accepted by users due to their favorable performance and hygienic properties. Common types include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and PE water supply pipes. A typical pipe production line consists of a control system, an extruder, a die head, a sizing and cooling system, a haul-off unit, a planetary cutting device, and a material-turning rack. The line usually includes two extruders: the main extruder features a high‑capacity conveying sleeve and an efficient screw design, while a smaller auxiliary extruder is used to produce marking lines. When a plastic pipe production line encounters malfunctions, it can lead to surface roughness, vibration rings, or lack of vacuum—issues that directly affect product quality. Therefore, timely troubleshooting is essential to maintain high-quality output. PVC Pipe Applications: PVC pipes are manufactured primarily from PVC resin powder. They are generally categorized according to their intended use, including drainage pipes, water supply pipes, conduit pipes, and cable jacketing pipes. Since the raw material formulations differ, the resulting pipes exhibit varying levels of pressure resistance and other performance characteristics. PVC water supply pipes, paired with appropriate fittings, are commonly employed in residential water supply systems, whereas PVC drainage pipes serve sewage disposal purposes.

The main machine includes the extrusion system, transmission system, heating system, and die head. The extrusion system mainly comprises the screw and barrel. The transmission system drives the screw, providing torque and rotational speed. The heating and cooling system regulates temperature during operation. The die head shapes the final product. Auxiliary equipment includes machines required for completing the process, such as traction devices, cooling units, cutting mechanisms, winding systems, and weighing devices. The control system primarily consists of electrical components, instrumentation, and actuators. Advantages 1. Utilizes a specially designed screw, barrel, die head, and die mold for silicone, along with a water circulation system that ensures internal vulcanization. 2. Employs a self-centering die head and either automatic or manual water-cooling control systems tailored specifically for silicone applications. 3. Equipped with a precise automated detection and feedback system, ensuring all wire parameters meet standards, reducing scrap rates, and significantly lowering costs. 4. Features a multi-layered circumferential vulcanization oven design—featuring a high-temperature shaping oven at the front end and a coil-wrapping structure at the rear—extending the vulcanization time, improving vulcanization efficiency, and ultimately boosting production output. 5. Incorporates a combined design of cable storage racks and ovens, allowing overlapping placement to save valuable floor space. 6. Includes a feed roller synchronized with the screw, enabling automatic material intake by the main machine without the need for additional feeding devices. Characteristics of Silicone Rubber Cables 1. Long-term operating temperature of the conductor: 180°C. 2. During short-circuit conditions (lasting up to 5 seconds), the conductor temperature does not exceed 350°C. 3. Permissible bending radius: For cables without armor or shielding, the minimum bending radius should be no less than 10 times the cable’s outer diameter; for armored or shielded cables, it should be no less than 12 times the outer diameter. 4. Installation temperature: Not lower than -20°C; if installation occurs below this threshold, the cable must be preheated. This machine is ideally suited for producing insulated or sheathed wires using silicone tubing, offering convenient operation.

Its innovative design, including an advanced feeding mechanism, ensures excellent production stability while reducing operator workload. The high compression ratio and long length-to-diameter ratio of the screw enhance extrusion density and mixing uniformity, resulting in products with smooth inner and outer surfaces, no air bubbles, and consistent dimensional accuracy. Key Performance Features of the Silicone Strip Extruder 1. Equipped with an AC motor and variable-frequency drive, this machine offers a wide speed range, enabling flexible adaptation to various silicone rubber product specifications and convenient operation. 2. It utilizes a hardened gear‑surface rubber extruder reducer, providing low noise, high transmission torque, smooth operation, and easy maintenance. 3. Featuring pneumatic forced feeding, it can process multi‑layer rubber strips, ensuring dense extrusion and superior product quality. 4. A dual‑channel automatic temperature controller maintains minimal temperature fluctuations during heating, allowing precise selection of optimal heating temperatures based on specific processing requirements, while automatically regulating set temperatures for both the barrel and die. 5. The barrel employs electric heating combined with circulating cooling, enabling rapid material cooling to prevent thermal degradation. After extrusion, silicone products pass through a front‑mounted high‑temperature vulcanization tunnel for preliminary vulcanization and shaping, followed by a rear tunnel for thorough curing. This approach resolves longstanding production and quality challenges inherent in traditional silicone rubber extrusion and vulcanization processes, such as: - Ensuring roundness and preventing deformation in thin-walled extruded tubes; - Producing large‑diameter and thick‑walled silicone tubes without surface indentations; - Achieving precise cross‑sectional shapes for complex profiled silicone strips; - Delivering accurate dimensions and forms across a hardness range from 30° to 70° Shore A. The tunnel features double-layer stainless steel construction, offering excellent insulation, extended heat retention, energy savings, and an aesthetically pleasing appearance. Quartz heating elements provide high temperatures and efficient radiant heat transfer, shortening vulcanization time and improving thermal efficiency. Once the tunnel reaches the preset temperature, it automatically switches to constant‑temperature control, deactivating one heating zone to conserve energy. This equipment is ideal for manufacturing silicone tubes, strips, custom profiles, foamed tubes, and more. With short vulcanization times and high productivity—yielding approximately 60–180 kg per hour—the machine is easy to operate. Silicone Tube Equipment Usage and Maintenance 1. Before use, fill the hardened gear‑surface reducer with appropriate lubricant: summer-grade gear oil or winter-grade No. 45 mechanical oil. Regular replacement extends the reducer’s service life. 2. Prior to starting the silicone tube extruder, verify the power supply to prevent motor damage caused by poor electrical contact. 3. Before operating the vacuum head, tighten all screws and securing components; after shutdown, thoroughly clean any residual adhesive. Adjust the core position upon startup. 4. Before use, inspect the barrel and screw for metal contamination to avoid potential damage. Before stopping, ensure all adhesive has been fully extruded to prevent leftover cured material from affecting subsequent operations. 5. (1) Clean the gearbox oil tank and check gear meshing for wear; adjust belt tension appropriately and periodically apply wheel lubricant. (2) Remove any cured adhesive from the barrel and internal cavity to prevent leakage and maintain proper water circulation within the machine’s jacket. (3) Routinely inspect bearings and rotating shafts in the vulcanization chamber for signs of wear or looseness, replacing worn parts as needed. Also, examine the heating and sealing systems, replenishing heating elements if required, and clear ventilation ducts to ensure smooth rotation.
