Upgraded Molding Process: Redefining The Protective Performance Of Parallel Groove Clamps

In the field of power fittings, the long-term operational reliability of burndy parallel groove clamp is directly related to the safety and stability of the power transmission network. Traditional installation methods often rely on external environmental isolation measures, but the introduction of molding installation technology is changing this situation from the manufacturing source.

From Physical Encapsulation to Structural Integration

The molding installation of the connector parallel groove clamp is not simply an additional protective layer. Through integrated molding with an injection mold, the insulating material and the metal matrix form a tight molecular-level bond under high temperature and pressure. This process eliminates gaps and pores that are difficult to avoid in traditional installations. After the molding process is completed, the insulating sleeve and the clamp body form a complete composite structure, eliminating the penetration channels for external moisture, salt spray, and contaminant particles.

The fundamental improvement in protection level stems from the optimization of interface management. The male and female molds in the mold design precisely match to ensure that the insulating material is evenly filled around every complex curved surface of the clamp. This comprehensive encapsulation not only isolates the electrolyte but also buffers the material stress caused by outdoor temperature changes.

Process Details Supporting Protective Performance

To achieve the protective value of molded installation, several technical aspects require strict control:

• Mold Cavity Pressure and Temperature Profile: The pressure provided by the injection cylinder must be maintained stably to ensure sufficient flow of the insulating hot material within the mold cavity and complete removal of residual gas. Temperature control affects the cross-linking density of the material; insufficient density reduces corona resistance.

• Material Interface Cleanliness: Before molding, the oxide layer and oil stains on the groove clamp metal surface must be thoroughly cleaned. A clean interface is fundamental for insulation layer adhesion; localized contamination can induce partial discharge during high-voltage operation, gradually eroding the protective layer.

• Post-Demolding Auxiliary Treatment: After the molded insulating sleeve is ejected from the mold, its edges and ports should remain intact and smooth. Sharp edges or burrs may become areas of concentrated electric field, affecting the overall protection lifespan.

For electrical connections, improved protection levels also mean long-term stability of contact resistance. The molded layer physically isolates the crimping point from the atmospheric environment, and the metallographic structure inside the parallel groove is no longer threatened by electrochemical corrosion. Molded clamps exhibit longer maintenance-free cycles in heavily polluted areas and coastal regions. This process transforms reactive protection into proactive structural design, allowing the connection point to truly have the potential to last as long as the line itself.
