Maintaining a Consistent Finish Means Watching the Thermometer

Weather conditions significantly impact the quality of metal finishing processes. Temperature variations—from cold winters to hot summers—affect various process tanks and solutions. Proper temperature control is crucial to avoid issues such as sludging, poor heat transfer, and ineffective surface preparation. This white paper explores the effects of temperature on different aspects of metal finishing, including surface preparation, rinsing, plating baths, and equipment. It provides strategies for maintaining optimal performance year-round, ensuring consistent and high-quality finishes.

• Surface Preparation: Temperature affects soak and electro cleaners, acids, and zincates. Maintain appropriate temperatures to avoid sludging, poor conditioning, and slow film formation.
• Rinse Water: Cold rinse water is less effective; warm it to at least 70°F (21°C) for better results.
• Plating Baths: Control temperatures for room-temperature baths and consider exceptions like acid tin plating and anodizing. Chilling certain baths can be beneficial in winter.
• Chromates: Operate within recommended temperature ranges to ensure proper film formation and corrosion protection.
• Equipment: Ensure heating systems are compatible and functioning correctly. Regular maintenance and preparation for temperature extremes are essential.
