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.

Types and Characteristics of Silicone Tube Extruders

A silicone tube extrusion molding unit typically consists of an extruder main machine, auxiliary equipment, and a control system. The main machine comprises the extrusion system, the drive system, the heating system, and the die–die head assembly. The extrusion system primarily includes the screw and the barrel. The drive system is responsible for powering the screw, providing the necessary torque and rotational speed. The heating and cooling system regulates the temperature throughout the process. The die–die head assembly shapes the final product. Auxiliary equipment encompasses machines required to complete the manufacturing process, such as traction units, cooling systems, cutting devices, take‑up units, and weighing systems. The control system mainly consists of electrical components, instrumentation, and actuators.

Advantages

1. A silicone rubber molding process employing a screw, barrel, die head, and die plate, with a water‑circulation system designed to facilitate vulcanization within the mold.

2. It employs a self-centering chuck with no alignment required and a water-cooling system, available in either automatic or manual control modes.

3. Equipped with a precision automatic inspection and feedback system, it ensures that all wire‑related parameters meet specifications, reduces scrap rates, and significantly lowers costs.

4. The design incorporates a multi-layer, circumferential vulcanization oven: the front section features a high-temperature vulcanization and shaping oven, while the rear section employs a coil‑encircling structure. This configuration extends the vulcanization length of the silicone rubber, enhances the efficiency of silicone wire vulcanization, and thereby boosts overall production throughput.

5. A combined design integrating a wire‑storage rack and an oven allows the two to be stacked, thereby saving installation space.

6. The design incorporates a screw‑synchronized feeding roller, enabling the main unit to automatically draw in material without the need for an oil‑lubricated feeding device.

Operating Characteristics of Silicone Rubber Cables

1. Long-term operating temperature of the cable conductor: 180°C.

2. During a short circuit (lasting 5 seconds), the temperature of the cable conductor shall not exceed 350°C.

3. Permissible bending radius of cables: For cables without armor or shielding, the radius shall be no less than 10 times the cable’s outer diameter; for cables with armor or shielding, the radius shall be no less than 12 times the cable’s outer diameter.

4. Cable laying temperature: Not less than –20°C; when laying at temperatures below this threshold, the cable shall be preheated.

This machine is suitable for producing silicone‑rubber‑insulated or sheathed wires and is easy to operate.
