The production process for silicone rubber cable extrusion involves several steps to create high-quality cables. Here is a detailed explanation of the process:
Raw Material Preparation:
Silicone rubber compounds are formulated using a combination of silicone polymers, fillers, additives, and curing agents.
The compounds are mixed and processed to achieve the desired properties such as flexibility, temperature resistance, and electrical insulation.
Extrusion:
The silicone rubber compound is fed into an extruder, which consists of a rotating screw inside a heated barrel.
The compound is heated and melted as it moves through the extruder, creating a consistent and uniform material.
The molten silicone rubber is forced through a specially designed die, which shapes the cable into the desired profile.
The extrusion process ensures that the cable has the required dimensions and cross-sectional shape.
Curing:
After extrusion, the silicone rubber cable is cured to achieve its final properties.
The curing process can be done using different methods such as hot air, salt bath, microwave, or steam vulcanization.
The cable is passed through a heated cure oven, where it is exposed to the appropriate curing conditions.
The curing process allows the silicone rubber to cross-link and form a stable and durable material.
Cooling and Finishing:
Once the cable is cured, it is cooled using either water or air to bring it to room temperature.
The cooled cable is then cleaned to remove any residues or contaminants.
The cable is inspected for quality and undergoes any necessary finishing processes such as cutting, stripping, or marking.
