Leoni has strengthened its systems business and is meeting the growing demand for ready-to-connect, thermally and mechanically stable as well as pressure-sealed solutions for medical technology applications.
Leoni, a European provider of cables and cable systems to the automotive sector and other industries, has enhanced its expertise in the manufacture of overmolded connections for medical equipment.
In both high and low pressure processes, Business Unit Healthcare overmolds thermoplastic and elastomer plastics; for example, two-component injection molding of liquid silicone rubber (LSR). The company’s technology park was recently extended with additional production lines at its various manufacturing facilities.
Leoni has strengthened its systems business and is meeting the growing demand for ready-to-connect, thermally and mechanically stable as well as pressure-sealed solutions for medical technology applications.
In its production of cable systems for medical technology, Leoni uses various semi-automatic injection and overmolding techniques to process thermoplastics, thermoplastic elastomers and LSR. In addition to the injection molding machines at various of its production facilities, Business Unit Healthcare can draw upon a broad range of special hot-melt devices.
The preferred material for overmolded connectors, grommets and v-splitters for endoscopy systems is LSR. Combined with an LSR cable jacket, Leoni supplies flexible, gastight and autoclavable systems.
Leoni develops application-optimized component geometries and the necessary tools. Which processes and materials are deployed will depend on the application of the overmolded components.
The materials of the cable jacket and the overmolding will normally match in order to achieve a good connection. Alongside silicone, Leoni also processes such other biocompatible materials as FEP, ETFE and TPU for near-patient applications.
For mechanically demanding applications in device wiring, Leoni overmolds its cables located outside or inside with such technical plastics as thermoplastics or thermoplastic elastomers or overmolds electronic components with (thermoplastic) thermal fusion adhesives. A further shield is added if required.
Leoni can also overmold plastics that are up to 30% glass fiber-strengthened in a high pressure process.
