Development Of Pre-insulated Bushings Driven By Extrusion Processes
In the modern electrical industry, pre insulated sleeve is typically produced through extrusion molding, a process that determines the dimensional accuracy and material uniformity of the bushing. Through extrusion molding, pre insulated junction sleeve maintains continuous structural consistency, providing a stable foundation for subsequent processing. During manufacturing, temperature and pressure control directly impact product stability.
Material Selection and Extrusion Conditions
-
Material Type: Extruded pre-insulated bushings often use insulating materials such as polyethylene and polyvinyl chloride. The molecular structure and flow characteristics of the material affect the bushing's molding quality.
-
Temperature Control: Different materials require matched extrusion temperatures; excessively high temperatures can cause bubbles and deformation, while excessively low temperatures can lead to uneven flow.
-
Pressure Regulation: Extrusion pressure affects the uniformity of bushing wall thickness and surface smoothness.
These factors combined enable insulated joint sleeve to achieve consistency in both mechanical and insulating properties. The extrusion process allows for long-length production, reduces seam treatment, and facilitates continuous operation of automated production lines.
