CPP – Coating Preparation Plant

Precision that eliminates scrap. Quality that builds your advantage.

In modern foundry practice, the battle for margins is fought by reducing component finishing costs. Although the cost of a refractory coating (dressing) typically accounts for less than 1% of total production costs, its incorrect application can compromise the entire metallurgical process. A defective surface leads to extra man-hours for cleaning, machining, and in the worst-case scenario – costly scrap.

The Challenge: Say goodbye to human error and the Ford cup

Traditional control methods based on periodic viscosity measurements (e.g., using a Ford cup) are imprecise. The result depends on ambient temperature, operator reaction time, and subjective judgment. This leads to process instability.

The Teknomatik Solution: The CPP (Coating Preparation Plant) system is an intelligent response to these challenges, automating the preparation and distribution of both water-based and alcohol-based coatings.

Features and Benefits of the Automated Protective Coating Preparation Station

Our installation takes full control over coating parameters, offering benefits unattainable with manual methods:

  • Continuous Density Monitoring: The use of a high-precision probe allows for readings accurate to 3 decimal places, completely independent of the operator.
  • Temperature-Independent Stability: The system automatically adjusts the mixture composition, maintaining a constant solid content regardless of the ambient conditions in the hall.
  • Guaranteed Consistent Layer: Stable rheological parameters translate to repeatable "wet" layer thickness on every single component.
  • Economy and Ecology: Precise dosing means lower coating consumption and a drastic reduction in scrap rates (cores and molds).
  • Safety and ATEX: For solvent-based coatings, we offer versions compliant with ATEX standards, minimizing fire risks and improving the working environment.
  • Full Traceability: The system collects process data, enabling comprehensive quality control and historical analysis.

Advanced Technical Configuration

As a machinery manufacturer with years of experience, we design coating preparation stations based on proven, top-tier components:

  • Tanks: Storage tanks (1000-2000 l) and preparation tanks (300-500 l) equipped with mechanical agitators and recirculation mixing systems.
  • Dosing System: Automatic dosing of the carrier (water/alcohol) and the possibility of integration with a dosing system for dry fillers.
  • Pumps: High-performance diaphragm pumps resistant to the abrasive nature of refractory components.
  • Filtration: Modular inline filters that effectively remove contaminants (e.g., sand) from the circuit.
  • Automation: Advanced controller that adjusts parameters in real-time based on density readings.
  • Industry 4.0 Ready: The CPP system can be fully integrated with our robotic cells for automated core dipping or coating spraying.
