Wire trough extrusion production line: precise wall thickness control and multiple material selection to shape high-performance wire trough

The wall thickness of the wire trough is a key factor affecting its structural strength and electrical insulation performance. If the wall thickness is too thin, the wire trough may deform or even break when carrying cables, affecting the safety and stability of the electrical system; if the wall thickness is too thick, it may increase material costs, reduce installation efficiency, and is not conducive to environmental protection and energy saving. Therefore, the wire trough extrusion production line needs to have the ability to accurately control the wall thickness.

Screw speed is one of the key factors affecting the material flow rate and extrusion pressure during the extrusion process. The wire trough extrusion production line can achieve precise control of the material extrusion rate by adjusting the screw speed. High speed means that the material stays in the extruder for a shorter time, which is conducive to reducing the degradation of the material caused by long-term high-temperature heating, but it may also cause insufficient extrusion pressure and affect the uniformity of wall thickness. On the contrary, although low speed can increase the mixing and plasticization of the material in the extruder, it will reduce production efficiency. The wire trough extrusion production line needs to reasonably set the screw speed according to different material and wall thickness requirements to achieve the best balance between output and quality.

Heating temperature is another important factor in controlling the melting state and fluidity of materials. Wire trough extrusion production lines are usually equipped with multi-stage heating systems, which can heat the materials in sections to achieve more precise temperature control. By accurately adjusting the heating temperature of each section, it can be ensured that the material reaches the ideal melting state during the extrusion process, neither overheating and degradation, nor overcooling and causing extrusion difficulties. At the same time, the heating temperature is also closely related to the plasticization degree and extrusion pressure of the material, which in turn affects the wall thickness uniformity and surface quality of the wire trough.

Extrusion pressure is an indispensable part of the wire trough extrusion process, which directly affects the extrusion speed and extrusion volume of the material. The wire trough extrusion production line can accurately control the extrusion pressure by adjusting the size and shape of the die outlet and the back pressure setting of the extruder. Reasonable extrusion pressure can not only ensure that the material is evenly distributed in the die, but also effectively prevent uneven wall thickness caused by uneven material flow. Extrusion pressure also interacts with the melting degree and extrusion temperature of the material to jointly affect the wall thickness and surface quality of the wire trough.

In addition to wall thickness, the material of the wire trough is also an important factor affecting its performance. Wire troughs of different materials have different physical, chemical and electrical properties and are suitable for different application scenarios. The cable trunking extrusion line provides a wealth of choices for different industries by supporting the extrusion of a variety of materials.

PVC (polyvinyl chloride) has become one of the most commonly used materials in cable trunking manufacturing due to its good insulation performance, corrosion resistance, flame retardancy and relatively low cost. The cable trunking extrusion line can produce PVC cable trunking with excellent physical and electrical properties by precisely controlling the melting temperature and extrusion pressure of PVC, which is widely used in construction, electrical engineering and communications.

ABS (acrylonitrile-butadiene-styrene) is widely used in the manufacture of cable trunking that requires high mechanical properties and aesthetic requirements due to its high strength, good processing performance and surface gloss. The cable trunking extrusion line can ensure that the ABS material is fully plasticized during the extrusion process by optimizing the extrusion process parameters, such as increasing the screw speed and heating temperature, so as to produce ABS cable trunking with excellent mechanical properties and surface quality.

PE (polyethylene) is increasingly used in the manufacture of cable trunking that requires environmental protection due to its non-toxic, odorless, environmentally friendly and durable characteristics. The cable trunking extrusion production line can ensure that the PE material remains in a stable molten state during the extrusion process by precisely controlling the heating temperature and extrusion pressure of PE, thereby producing PE cable trunking with excellent physical properties and environmental protection characteristics.

The cable trunking extrusion production line achieves precise control of the cable trunking wall thickness by precisely controlling key parameters such as screw speed, heating temperature and extrusion pressure, thereby ensuring the physical strength and electrical performance of the cable trunking. The production line also supports the extrusion of multiple materials, such as PVC, ABS, PE, etc., providing a wealth of choices for different application scenarios. This combination of precise control and multiple choices not only improves the production efficiency and product quality of the cable trunking, but also meets the urgent needs of different industries for high-performance cable trunking.
