The SCA system controller directs all main functions and components of paint shop sealing and dampening applications. It offers efficiency and traceability in high-performance production lines. Its modular design is easy to adapt to customer specifications and production conditions. A user-friendly menu system displays fundamental production status conditions such as conditioning and heating, meter fill levels, and material circulation. A signal trace tool provides visibility of all application parameters for fault analysis. For easy operation, an integrated HMI and a central, external HMI are available. The connection from the SCA application controller to the robot controller can be realized with all common industrial field bus systems.
The selection of the metering unit is dependent on the customers’ requirements for flow, volume, and pressure. SCA metering systems are optimized for highly precise applications. Due to the robust construction and high-power drives, SCA meters are suited for highly dynamic cold or heated applications in the most demanding environments. The tandem configuration of two shot meters working in parallel enables endless application. This reduces filling times and application pauses, thereby maximizing productivity.
For high-quality applications, customers can choose from a variety of rotatable, multi-nozzle applicators. By using a rotary applicator, the hose package does not restrict the flexibility of the robot and leads to a better accessibility. Multi-nozzle applicators enable the use of up to 4 different nozzles as well as different angles and positions. A re-circulation system to the nozzle is usually integrated to stabilize application conditions due to the material properties.
To meet customer requirements for bead shape and size, a broad range of standard and customized nozzles is available. Ultimately, the type of nozzle that is selected in combination with the applicator determines the shape. In paint shop applications, a wide variety of different nozzle types are used, such as flat stream, jet stream, multi-orifice, extrusion and airless nozzles.
The SCA material supply solution for paint shop applications is available as 1000 l/300 gal barrel version. The utilized displacement pump UP 1200 is characterized by a very high volume flow and high pressure. The robust design of the UP 1200 enables a long lifetime and easy maintenance. In case of long distances from the material supply to the application cell, the UP 1200 can also be used as booster pump.
PVC is a commonly used material for sealing the car body and its viscosity is highly sensitive to temperature fluctuations. To get constant application conditions, a Peltier conditioning system (PCS) can heat or cool the material regardless of ambient temperature. The PCS is fully integrated into the application system and can be operated from the application HMI.
PVC residuals on the nozzle is a well-known problem in paint shops The Borster NCS is a standalone nozzle cleaning system with an automatic switch-on functionality. It is easy to retrofit or install to your existing line without any hassle or time spent on training. Its user friendliness allows for quick maintenance with no tools needed. The pre-installed cleaning programs make sure that the Borster NCS delivers perfect cleaning results, all while keeping a low level of noise disturbance.
Paint shop production lines with a high variety of car models need flexible solutions. The SCA tool changing station allows the use of different nozzle shapes for various car designs. The whole nozzle carrier of an applicator can be exchanged automatically and equipping the nozzle can be optimally aligned to the car’s geometry. For different designs, diverse variants are available that can be flexibly adapted to customer requirements.
