Ultrasonic 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 transfomers or thermal switches used within motor windings and cable harness.

 

Multilayers ultrasonic welded spiral winding endcaps provide a hermetic seal on one side that guarantees perfect and fast positioning, also thanks to the heat shrink technique.

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

 

The ultrasonic seal is based on multi-layered spiral winding  tubes.

 

We supply the following ultrasonic welded endcaps:

 

  1. Mylar A caps  endcaps - Polyester A caps endcaps
  2. Mylar HS caps endcaps - Polyester HS caps endcaps
  3. Nomex 410/Mylar A caps endcaps - Nomex/Polyester A caps endcaps
  4. Nomex 411/Mylar HS cap endcaps - Nomex 411/Polyester HS caps  endcaps
  5. Low shrink caps endcaps - Type AHS, 2 LSO
  6. Class F Non woven caps endcaps
  7. Kapton caps endcaps - Polyimide caps endcaps

 

All raw materials used, including Polyester A (Mylar® A) are supplied by the industry’s world leaders, are all UL certified and provide excellent electric, thermal, chemical and environmental insulation.

 

Accurately combined, they can be used in a wide range of temperatures between -269°C and +400°C. We also offer ultrasonic seals using Polyimide films. Endcaps are supplied with internal diameter ranging between 2 and 130 mm and thickness between 100 and 600 micron.

 

The standard seal length is between 4 and 5 mm; different seal lengths can be set based on our customers’ needs. Endcaps are also supplied in custom colours, including stripes for easy identification

 

Adhesives in all products meet REACH and ROHS standards and guarantee that the original properties of the films used are fully maintained.
