Extrusion: 0.5 to 3 W/cm². Injection: 0.5 to 5 W/cm². Other watt densities can be manufactured if the system can absorb the generated heat.
For certain band heater types an external clamp can be added. It is especially useful for threaded bridges used to hold thermocouples or terminal protection boxes.
This band heater is made from a brass tube. The heating coil and insulation are placed inside. Cable exit is only at 180° from the clamp; orientation can be tangential, radial or axial, usually at 45°. Especially suitable for injection nozzles where plastic leakage is common.
This band heater maximizes the heated area, leaving only 5 mm cold at each end. Recommended where the heated surface must be maximized and it is not possible to install two narrower bands with offset clamps. The cable exit is as shown in the photo and can include additional spaghetti sleeving and braided metal mesh protection on request.
There are areas where for safety reasons it is not acceptable to have exposed screws. In other places, it is necessary to have connection systems that allow for quick replacement of elements. To address these situations, there are single-pole bushing outputs. These consist of a brass piece that protects the electrical connection. This type of connection is complemented by single-pole ceramic or silicone plugs, which allow for the disconnection of the heating band without cutting off the power or stopping the production process.
This type of outlet is very useful in the case of nozzle-type outlets, where the injection machine advances so deep into the support plate that it makes it impossible to exit the screws, and in the case of outlets with cable outlets, due to their flexibility they end up touching the cast plate and are damaged by friction. The outlet with a remote terminal block provides a solution to all these problems, since the maintenance operator can give the outlet its final shape before the nozzle of the injection machine advances to the working position.
