Ultrasonic dot welded spiral winding caps - endcaps

 

These precision products are electrical insulating caps - endcaps for insulating electrical components such as crimping terminals and connections to magnet wires within electric motors, connections in motors and transformers , cable harness or thermal switches used within motor windings.

 

Multilayers ultrasonic dot welded spiral winding encaps have the advantage of narrower seal widths compared to classic ultrasonically sealed ones, which run the entire length of the tube.

This special closure eliminates potential problems of damaging wirings because of sharp edges and reduced thickness.

 

 

They are mainly used to secure and insulate wire connections in hermetic electric motors ; they also provide secondary insulation,  mechanical and chemical protection for wiring looms.

The product offers perfect and fast positioning, also thanks to the heat shrink technique.

 

We supply the following ultrasonic dot welded endcaps:

 

1. Mylar A caps  endcaps - Polyester A caps endcaps

2. Mylar HS caps  endcaps - Polyester HS caps endcaps
