The manufacturing of Automotive Wiring Harness Protection Sleeve lies in its extrusion technology advantages

Braided Sleeve use extrusion as a physical manufacturing technology, which is much better than the past hot pressing or hot stamping technologies. Together with the new process technology for extruded Braided Sleeve, which uses CO2 to set the shape in the liquid state, the so-called redeveloped process in Braided Sleeve production combines the advantages of physical extrusion and chemical manufacturing. Like chemical foam masterbatch, raw Braided Sleeve are fed into the extruder through a pellet hopper.

No modifications are required to the extruder itself. Another benefit is that, as a physical car wiring harness protector, dry ice does not leave any residue like water that reacts with squeeze out. Therefore, it is also suitable for hydrolysis-sensitive materials. New metering technology enables feeding dry ice pellets through metering screws and gravity mixers directly into the feed zone of the extruder. In this way, the IKV research team was able to avoid premature dry ice sublimation and cooling of the plastic particles. By pressing against the plastic and melting it rapidly, the dry ice dissolves in the melt. IKV has extensively tested new metrology technologies and developed associated process windows.
With new process technology, Braided Sleeve densities of 350-950 kg/m² (such as LDPE) are achievable, which is comparable to chemical Braided Sleeve. By adjusting the process temperature, the method can also be applied to other plastics such as polypropylene. Despite the relatively high sublimation losses measured in automotive wire harness protective jackets, the process can compete with chemical Automotive Wiring Harness Protection Sleeve jackets due to the lower cost of CO2. This process allows inexpensive entry into foam extrusion since any modification is limited to metering technology. Many technical advantages can be incorporated into the production process of today's Braided Sleeve.
