| Résumé : |
Aside from offering high mechanical strength, versatility and durability, polymer materials are ideal for applications in the electrical industry because of their ability to isolate electrical current. For the production of connectors, Harting processes liquid crystal polymer (LCP), which lends itself to the production of intricate, thin-walled molded parts. LCP processing relies on hot runner systems that can guarantee a uniform thermal balance. |
| Note de contenu : |
- The complexity of simplicity
- Hot runner nozzles with a very good thermal profile
- Thermal balance in the hot runner is essential
- Punched strip accumulator installed upstream of the IM machine
- 25 years' experience of LCP processing
- Figure : For the conduction cooled MicroTCA systems, Harting processes LCP, a material that is flame-resistant, dimensionally stable at high temperatures, chemically resistant, and has only a low thermal expansion
- Fig. 1 : Harting’s polymer molding shop also designs and adapts many new injection molds based on its own practical experience
- Fig. 2 : Minimal cavity spacing, as can be seen here in a trade show exhibit fitted with the patented Blue Flow thick-film heating element (see Box p. 22), is key for many applications
- Fig. 3 : "Lined up end to end, the 85 contact segments form the backplane for the printed circuit board," explains Mark Gosewehr
- Fig. 4 : A camera checks that the 85 contact segments are correctly positioned. Only then is the strip carrying the segments fed automatically into the injection mold |
