Design Philosophy: Highly flexible systems with space-saving layouts and low operating expenditure, planned from the outset.
Optimization Approach: Cross-process strategies to unlock potential in energy consumption and coating quality.
Resource Efficiency: Continuous filtration of process liquids to reduce chemical and water consumption.
Proven Technologies: Examples include the rotational dip process and the optimized anode control system.
From washing and surface conditioning to final sealing, there are numerous methods available to pretreat a substrate before coating. Each step comes with its own advantages and limitations. The purpose of pretreatment is to ensure the surface can properly receive the coating, maintain its quality for the longest possible time, and protect it against corrosion—while also removing contaminants such as grease, grime, and insect residue. These procedures and dwell times exist for good reason; skipping or shortening them will quickly lead to unsatisfactory outcomes.
