-----Drying Method for Stampings
1998I'm looking for an alternative drying method for metal stampings. We have been using a "Holland" centrifugal dryier for many years and with excellent results. However, due to the complexity of a new part, we must avoid the spining motion.
Any ideas?
Parts are about 1" long, made out of SS, tubed, degreased, rinsed and finally dryied. We expect a yearly volume of about 16MM
ALEJANDRO AGUILERAIf you can afford to rack the parts, a box-type heated recirculating dryer is a simple and proven technology. If you can't afford to rack them, the practical problem is that for energy efficiency and to reduce staining, you usually want to get air flow past the parts, and that means you need to get them separated from each other. If you are handling them in bulk, you won't get that flow. So what you would need is a screw type dryer or a belt dryer that uses a metal cloth.

We have noticed that a hot water dip prior to the hot air bow Ted mentioned above will help accelerate the drying process especially for relatively thin and light weight parts.

You may consider a vibrating corn cob dryer. In this method the parts are placed wet in warmed corn cob chips (Grit-O-Cob) in a vibrating unit that moves the parts to a shoot where the cobs are separated over a sieve. I have seen it used for drying mass finished & plated cutlery where a spin dryer would bend the parts.

A dip in a warm solution of isopropyl alcohol ⇦ on eBay or Amazon [affil link] and water will allow a air blower to rapidly remove the remaining water with minimal spotting. DI water really helps also.
