bdtronic is expanding its product portfolio and will in future be offering standardized industrial ovens for optimum heat treatment during dispensing. The ovens are used to cure potting compounds such as epoxy resins, polyurethanes and silicones or to preheat components to a specific temperature.
This is used in a wide range of different components, such as in the production of power electronics, on-board chargers (OBC) for hybrid and electric vehicles, base stations in the telecommunications sector, sensors for autonomous driving, or tire pressure sensors in the automotive electronics sector. To protect these from external influences such as dirt, moisture or overheating, they are encapsulated. For optimum potting results and the shortest possible cycle time, the components are in many cases preheated and the dispensed product is cured in a horizontal conveyor oven to ensure handling. In addition to the highly automated dispensing cell, bdtronic will in future also be responsible for manufacturing the oven technology itself.
Precise temperature management is essential for the impregnation of electric motors. Therefore, bdtronic already has many years of experience in thermal systems for impregnation systems. This knowledge is now used for the new standardized oven modules in combination with the dispensing solutions built by bdtronic.
The oven technology from bdtronic is so-called continuous ovens, in which the components are conveyed horizontally on up to two tracks. Each standard oven is equipped with a fan and a heating coil. The heated air is attracted by the fan and flows (longitudinal flow) through the interior of the oven. Due to the longitudinal flow, the parts are homogeneously heated or dried. In order to keep heat losses low, the furnace is equipped with a recirculation system, special insulation and bulkheads.
By integrating the oven modules into a production line, cycle and process times can be optimized, floor space can be saved and, in many cases, energy consumption can even be reduced through the intelligent use of process heat. In addition to economic advantages, this also increases process stability for series production.
