CONSUMABLES
Everything from a single source: We supply all the consumables you need for your system. This includes PTFE and cover strips, wiring or the appropriate heat-sealing band underlay.
CONSUMABLES
Heat sealing band underlay
The underlays for our heat sealing bands are adapted to the requirements of each individual application. Both flexible silicone underlays with various Shore hardnesses and non-flexible underlays are available. In addition to ensuring electrical and thermal insulation, underlays also compensate mechanical and closing tolerances, so that a homogeneous contact force is easier to achieve.
Hard, non-flexible underlays are ideal for cut-and-seal applications.
PTFE and cover strips
PTFE fiberglass is widely used as an anti-stick covering and insulating material. It therefore makes a perfect interlayer between the heat sealing band and the underlay. It allows the heat sealing band to slide in case of linear expansion without sticking to the underlay. The PTFE is adhered directly to the underlay, which is made of silicone, for instance.
Cover strips are PTFE fiberglass with a non-adhesive zone which are used directly on the heat sealing band. The non-adhesive zone is located above the heat sealing band, which can be fastened to the bar with the adhesive zone. Once again, the heat sealing band can slide in case of linear expansion but the film is prevented from sticking to it.
We can also offer you several suitable cables with different cross sections which are optimized for our control loop. The cables you need are described in the ROPEX Application Report along with the ideal cross section. Complicated wiring calculations are no longer necessary as a result.
The following cable types are available:
- C-HF-xx: Highly flexible high-current cable with silicone sheath
- C-TC-xx: High current cable suitable for drag chains
- UML-1: Twisted cable for voltage measurements
PEEK bar end blocks
Bar end blocks made from a special material and with a special geometry are employed in medical applications or whenever space is scarce. PEEK, the thermoplastic we use for this purpose, is resistant to high temperatures.
PEEK bar end blocks are readily machinable. Various different designs are therefore possible depending on the application.
Bar end blocks are attached to the ends of a heat sealing bar. Their function is as follows:
- To fasten the heat sealing band
- To connect the high-current and measurement cables
- To allow the hot heat sealing band to expand due to spring force
- To prevent the heat sealing band from bending or warping
Screwed electrical connections are essential here. Plug-in connections are not allowed because even minimal contact resistances will distort the temperature measurement. Since these connections are generally at one end, there is always a left and right-hand bar end block. Bar end blocks have different technical characteristics depending on the dimensions of the heat sealing band or the end pieces.
