Rapid Drying For Complex Geometry Parts

“Some pointers for your drying process.”
– Ethan Mueller

Q: How can I improve drying in the existing process?

A: You can invest in increasing the overall flow or number of air knives in an aqueous process, or you can implement the downstream solvent process, which you use for water displacement. There are several solutions, but it depends on your resources and what you expect your outcome to be.

Q: Can I use acetone or IPA for water displacement?

A: Yes. These are commonly used commodity-based products. Be cautious; they are flammable, volatile, and have a strong odor.

Q: Can I use mineral spirits for water displacement drying?

A: Yes. Mineral Spirits are not very volatile and do not dry quickly. It really depends on your downstream process. If you need a dry part that does not have liquid on it, this may not be the best process for you. It can prevent other issues associated with water, such as corrosion, where you have this slowly evaporating liquid on your part that does not cause rusting. Still, it is not really there to aid in quickly drying. It is more there to displace that water to prevent corrosion. Then you go to your downstream process, and hopefully, it will completely evaporate.

Q: Can I implement a vacuum degreasing system after an aqueous cleaning process?

A: In most situations, you could replace your aqueous process with a vacuum degreaser. There is some nuance to that, obviously. If you are trying to clean a part that might have polymerized oil or carbon oxidation, you may need that aqueous process stage.
