Saving Time & Money By Extruding Aluminum First, Finishing with CNC Machining

(Whitehouse Station, NJ – June 2019) For those looking to make the best parts and products from aluminum, a change to the way they approach the manufacturing process can lead to greater efficiency and profitability. The alternative method of extruding first followed by a CNC machined finish enables you to process higher volumes in considerably less time. One such provider who specializes in precision miniature extrusions is Minalex, with operations in Whitehouse Station, New Jersey.


When you’re combining miniature aluminum extrusions with the CNC machining to complete a job, you can build custom profiles of any product in a fraction of the time. Plus, you’ll find that you can also get the job started much faster using aluminum extrusions. High volume jobs can be done in a shorter period of time. You can do all the drilling or punching on your own because this is a quicker process, and you can extrude any aluminum product you want in any size. You’re literally, minutes away from die cutting everything you need. All in all, it means a finishing process, once delayed by days, can now be started on the same day, if not within the same hour!

Remember that every day you’re paying your team to complete as much work as they can, but if they’re constantly battling the problems created by inefficient manufacturing processes, their productivity can be severely impacted. And, so can your bottom line.


Back “in the day,” machining and manufacturing required you to take a much longer view of the work you did. You didn’t have the opportunity to get all your material extruded ahead of time, and you probably wasted a lot of time methodically going through each step of the process, since there was no other way to get the work done efficiently. Your materials were a lot rougher in the old days, and you had to finish all the raw material before you continued to use it.


The tolerances on product including micro aluminum extrusions are extremely tight, so more highly advanced products can now be made. When combined with aluminum CNC machining, just about any part imagined can be made, making this approach the most efficient way to work with aluminum.

Miniature aluminum extrusions can make all your projects easier. Here are just a few things that you can shift to this new way of working:

  • Angles
  • Holes that can be made by extrusion
  • Channel milling (e.g., LED lighting extrusions)
  • I-beams
  • Ten-foot stock squares

In the case of Minalex, for example, it can provide services, support and production in the following ways:

  • The jobs can be produced at very high volume as a much less expensive way to start the manufacturing process.
  • It can send the extrusions to the shop where the additional finishing will be done
  • It can perform secondary machine work without wasting time trying to cut down the aluminum in a more inefficient way.
  • From plane parts to gun parts and fishing parts almost every business sector can benefit


If you’re unaware of the miniature aluminum finishing process and think you have to produce the extrusions on your own, learn about the many ways Minalex and its manufacturing and finishing services can help you with custom profiles delivered right to your shop. It can make your operations more efficient, your tolerances tighter and your bottom line greener.
