Atomizing Nozzle Used in Copper Forming Applications

EXAIR Atomizing Nozzle, Narrow, Round Spray Pattern

 

Copper and its alloys are used in a variety of products from consumer goods like musical instruments, drawer and door pulls, wind chimes, electrical contacts and many other, similar parts that you do not see on more complicated pieces of equipment such as HVAC systems.

Comparatively speaking, copper is quite a malleable metal. That’s what makes it so useful for manufacturing processes such as expanding, reducing, flaring, beading and other similar processes that don’t necessarily involve a cutting or grinding action on the material, but rather a tool that comes into contact with the material to impart a specific shape that makes the made part beneficial to some other product or process.

And so, in the metal forming process, you generally have a hardened alloy tool that comes into contact with the soft copper (or brass) to impart one of the above mentioned effects to the material. With the metal forming process, you have friction that needs to be reduced substantially to aid in the forming process while maintaining the tool integrity and keeping heat generation to a minimum. There are a variety of oil-based lubricants that companies who specialize in this kind of processing, will use to lubricate the raw part prior to forming.

This is the point within the process where EXAIR Atomizing Nozzles can play a significant role in application of the lubrication. By atomizing the lubricant, the customer can have a controlled, even application of the lubricant to the tooling and/or material surface prior to putting the material through the forming operation. By applying a controlled layer of atomized lubricant, the customer can apply the lubricant in a sparingly manner to conserve on how much is used for each part formed. They get the benefit of the lubrication without over-doing it and wasting excess volume of lube applied. This, in turn, allows for a cleaner and safer processing area as well as measurable cost savings for the lubricant as well.

For lower viscosity lubricants (< 300 cP) that require only a light application of material, we have model AN1010SS which can provide a Narrow, Round spray pattern to coat smaller parts. If the part is larger or perhaps starts out as a sheet, we do also have model AW1030SS which can provide a Flat, Wide Angle spray pattern. If the lubricant has a viscosity that is higher than 300 cP, we also have a series of External Mix Atomizing Nozzles with similar spray flow patterns that can be selected for high precision adjustment of the liquid flow and droplet size to suit any need.

If you are in the metal forming industry and you are concerned with application of lubricants in your applications, we be glad to help you pick an Atomizing Nozzle to suit your needs. Contact us to discuss your application.
