Chamber spraying systems are mostly used within the metal industry. Adjustable nozzles spray a liquid cleaning medium onto the workpieces, which are supposed to be cleaned. Contaminations are thus dissolved and flushed from the workpiece by the energy of the spray nozzles.
Workpieces, which have surfaces that are difficult to access, are advantageously treated in immersion cleaning systems. They ensure that not only the external surfaces are treated but also all cavities. This type of pretreatment is particularly recommended for complex geometries where a spray system cannot reach the entire surface.
Flame treatment belongs to the physical surface treatment procedures,particularly of plastics. During flame treatment, the surface is briefly heated with a gas-flame with excess oxygen without beginning to melt the plastic.
Activating the surface
Specifically in the plastic coating field, but also in that of adhesive application, prior treatment of the surface with a flame is often required. We choose the optimal solution for you depending on the materials to be treated and the existing surface tension.
- Space-saving design
- System can be implemented on several levels
- Expandable conveyor system
- Fast and uncomplicated installation of the system

Don't let them put you on the chain
With conventional conveyor technology solutions, the entire transport of goods uses one conveyor chain, so that all components travel through the system at the identical, defined conveyor speed. As a result, all workpieces pass through the pretreatment, painting and drying processes with identical cycle times.
In comparison, with the ASF each transport unit has its own drive unit with an individual control unit. Each product carrier can thus be individually controlled as required. This enables variable process speeds within the system on the one hand and reverse travel within the process on the other.
That way, it is possible to drive through the coating cabins systematically at a lower speed and to drive through the plant at high speed on free transport routes. Consequently, processing cycle times of the ASF can be configured independently, resulting in significantly higher efficiency, lower process costs and faster throughput times.
The shuttles can bridge up to 250 mm without transport rails, which means that the conveyor rail can be interrupted, e.g. at fire doors or other fire sections, without restricting transport.
The advantages of the ASF drive concept:
- Speeds, directions of motion and stops are variable and reversible.
- Buffers allow any retrieval options (e.g. sorting function or use as "bag station")
- Product carriers can be individually controlled and regulated
- Different process speeds within the plant possible

AFOTEK, as a partner for turnkey painting systems, offers holistic solutions for complete electrical plant equipment.
The basis for the execution of the AFOTEK control technology are mainly automation solutions by Siemens. The individual control concept tailored to the needs of our customers usually consists of automation and visualization systems from the SIMATIC series. The complete functional operation and monitoring of the plant is realized via the visualization system.
The programming itself is carried out by our own qualified automation technicians and engineers to guarantee optimum support for our customers, even after plant commissioning. As standard, control programming is executed in the modern SIMATIC TIA portal in ladder diagram (LD) or in function diagram (FBD), if necessary also in structured text (SCL), instruction list (IL) or step chain programming (GRAPH, SFC).

AFOTEK- System visualization parameter overview.
A uniform and clear program and data structure with explicit descriptions enables the plant operator to easily diagnose and assign plant components. By using self-developed, standardized function blocks of the AFOTEK software library, we ensure the high quality of our control programming.

After the control programming is completed, we internally carry out a virtual commissioning. As part of the virtual commissioning, we test all functions and optimize weak points before commissioning. The result is a significantly shorter commissioning on our customers` site.
Remote access to the systems is provided via VPN routers at request of our customers. Release is executed via a key switch in the control cabinet. An included authorization system logs access and restricts the access to an authorized group of people. Remote access enables us to support our customers quickly and cost-effectively in fault analysis and troubleshooting.

Depending on the automation aspirations of our customers requirements, it is possible to record and provide energy, process and quality data and/or to connect higher-level systems (PLS, MES, ERP). For this purpose, we analyze the necessary processes together with our customers at an early stage in the project and document the necessary interfaces as a basis for the implementation of the interface.
Our services in the field of electrical and automation engineering:
- Project management of electrical and automation engineering
- Hardware planning and CAE design
- Production of switchgears
- Software project planning and visualization
- Electrical assembly and installation
- Commissioning and training
- Service and support
- Electrical maintenance
Your advantages of AFOTEK electrical and automation engineering:
- Qualified team of in-house automation technicians and engineers
- Intuitive, clear plant visualization
- System support via remote maintenance
- Shorter commissioning due to virtual commissioning
- Possible connection of the AFOTEK control to higher-level systems

AFOTEK Paint within the company process.
AFOTEK Paint is a tool, which is adapted to the needs of the system operator and which allows the simulation of the material flow in different forms (modules).
Module overview AFOTEK Paint.
The module AFOTEK Energy enables the expansion of the real time simulation and the plant planning by the simulation of energy consumptions. This enables an individual energy analysis for the different system and production variants under consideration of the customer specifications concerning local energy and gas prices. A calculated control of the processes can reduce energy consumptions. Furthermore, to simulate and optimize the operational costs of the painting system, alternatives to reduce energy consumptions are examined (for example using the emerging waste heat) already in course of this consideration. Finally, an increased environmental awareness leads not only to cost savings for the coating company but also to an image improvement.

Alongside a modern spray booth, effective methods and systems for seperating paint-sludge within the water circulation are becoming increasingly important.
RODAP is an efficient extraction system for removing sludge from solvent-based and water-soluble paints in the water circulation systems of paint sprayers.
The RODAP SR 185 WF works on the principle of partial stream treatment, i. e. only a portion of the circulating water is passed through the RODAP SR 185 WF. The sedimenting sludge is continuously added to the inlet water; this way the sludge is always floating and the device is self-cleaning.
The treated water is recirculated and fed back to the paint system together with the dripping water.
Using coagulants, the paint sludge is prepared for discharge (un-sticking, flocculation). A sludge scraper dumps it into the sludge catcher, from which it can be removed easily and properly disposed of.
