Automotive industry
When referring to the automotive sector, a particular type of oven is not identified nor a particular production process, in fact, ovens are used in many different processes including:
- Furnaces for treating brakes, clutches and other friction parts.
- Dryers or drying ovens for the evaporation of solvent-based products.
- Polymerization furnaces, drying furnaces for forming and treatments related to the production of composite materials.
- Furnaces for vulcanizing rubber moldings and other elastomers leading to the production of flexible hoses, seals, pneumatic hoses, etc.
- Furnaces for preheating, drying and curing resins used for the protective sealing of electrical components.
- Final products: ignition coils, diode bridges, starter motors, alternators, sensors, insulators, stators, injectors, etc.
- Furnaces for the polymerization and drying of liquid paints and powders.
- Furnaces for the thermal stabilization of headlights made of polymeric materials.
- Furnaces for preheating felt insulating materials before final forming.
- Ovens for drying polyurethane foam insulating materials.
On the other hand, what characterizes ovens in this area is the need for a high-quality final product free of imperfections.
In order to reach the required quality level, the ovens must be able to reproduce heating and cooling cycles and ramps with the greatest possible precision and the required characteristics, in terms of temperature control and absence of gradients inside the oven, are particularly stringent.
Overview of the coating production plant. In the center the preheating oven, and, downstream of it, the forming press and the machined pieces.
System for the heat treatment of friction material for brakes (ferodes).
Detail of the loading and unloading area.
Internal view of the ferodal heat treatment plant.
Highlighted is the movement system of the component support chain.
As is evident, the plants are sized according to the specific process/component and also to the modes of transport along the entire production line.
This oven manages the preheating phases of the stators and, after the impregnation phase, the polymerization phase of the resin.
Through the integration of oven electronics with barcode readers, the different processes are managed as well as the traceability of each component produced is ensured.
In analogy to what we have just seen, another application for the polymerization of the insulation of windings for electric motors intended for the automotive sector.
In this case, the determining constraint is that of containing the lateral bulk of the furnace.
To this end, a two-level oven was created (vertically developed carousel) equipped with an automatic loading and unloading mechanism for the trays containing the impregnated components.
