Negligible residue and part dryness are often the main justification for using “vanishing” or “evaporative” stamping lubricants—but what really distinguishes one residue from another—or how solvent-based products differ from water-based? Consider the following:
– application by other methods isn’t only wasteful—it impacts housekeeping, welding and finishing equipment and can dramatically shorten cleaner bath life. OPTIMIZE LUBRICANT APPLICATION AS A FIRST STEP.
2. Unless specified otherwise—the metal stock a stamper uses for their production will almost always have some sort of “processing &/or protective oil” on the material. Whether this is a “mill oil’, “pre– or post-lube”, specific rust preventive or rolling oil will vary based on which material you are using and how it is produced.
3. Consider unique customer specifications. Whether it is adhesive or refrigerant compatibility or FDA approval—there are numerous ways those specifications can be met. Some may not have even been properly investigated yet and could offer great benefits. Listen to your customer and be creative—you never know what solution you may come up with.
4. V.O.C. restrictions continue to tighten and be of concern to many manufacturers. In situations where this is the case—water-based fluids may be a strong option, but may require some slight changes in process.
5. The water-based fluids are very similar in base chemistries to many conventional, water-based stamping fluids. The point being—you may already have a solution to your goals currently used on your heavier duty stampings in your facility. The same product you are stamping heavy duty chassis components with may be able to replace your solvent-based evaporative lubricant at very low concentrations—further optimizing plant efficiency.
6. The use of properly applied and controlled “air knives” and/or “blowers” on parts and part conveyors provides a significantly drier part which can extend protection of parts in storage and also minimizes the amount of soils fouling welding tips and pretreatment baths.
7. Consider whether you want to use RTU/pre-diluted solutions or “use as received” solvent based products for your applications. These options offer little in the way of flexibility and economy compared to water-based stamping fluids applied properly, sparingly and at high dilution.
8. Consider whether your current stamping lubricant supplier has discussed these options with you to improve your safety and efficiency and, if not, give IRMCO a call to get started.
