Custom Metal Fabrication

Pre-processing of sheet metal for photo-chemical millingFaspro Technologies is a leader in custom metal fabrication, a value added process that involves the construction of products from various raw material including sheet stock. For us, custom metal fabrication means we build to your engineering drawings or fully develop the product on your behalf. Specialties like sheet metal fabrication using various methods including chemical etching can reduce time to market and improve product quality.

The added benefit of single sourcing development, prototyping and short run production reduces the need for purchasing staff to interact with multiple vendors and eliminates the issues present with shipping parts between vendors for processing.

After verifying the information on the engineering drawings, various metal fabrication processes are used to make the custom parts and apply some type of secondary operation like coating, painting, or assembly.

Photochemical milling is one of the manufacturing processes used in custom metal fabrication. Corrosive etchant is used to remove sheet metal where it touches the raw material. The raw sheet metal is protected from the etchant in areas that represent the final part. After processing, the metal is cleaned with a neutralizing agent and the parts may be separated or sent to another station for further processing.

Laser Cutting is a metal fabrication process that allows for fast and highly accurate feature placement and shape in sheet metal parts. This process is ideal for both prototype development and short run production because it is low cost and very repeatable.

When metal parts require a 3-dimensional shape, forming and drawing are the processes used to achieve high quality, low cost and fast turnaround. Factors that affect the performance of a die include metal thickness and draw depth. Faspro Technologies has years of experience in forming sheet metal parts and can guide the design of these critical part features.

After a part has been created, it sometimes needs to be electroplated and then assembled to other parts. Special techniques are required before and after these steps to ensure the parts meet the specifications on the drawing. Processes like deburring are used to remove sharp edges and polish the parts. Assembly through the use of brazing, soldering, welding or heat staking join two or more parts in a fixed assembly. In some cases, the assembled parts need to move relative to each other and manual assembly with pins, screws, springs, contacts and other components is required. Finally, the assembled parts may need to be kitted as a way to assist final production of a larger assembly. The parts and all fasteners or other attachment parts are contained in a kit, contents are verified and the kit is delivered to the final assembly location.

  • Thank you so much for the information about sheet metal fabrication. I really like the information about the photochemical milling process. I have only heard of laser cutting before, but now I know that there are multiple processes in custom sheet metal fabrication. Are there any more processes involved besides these two?

  • It seems like there are so many options to get metal fabrication done! This is really convenient for various businesses that need it, though. I especially like that it can be laser cut to make really precise shapes. I am sure this is really helpful for certain projects that require really specific pieces. Thanks for the information on how metal fabrication works!

  • Metal fabrication sounds like a very fascinating field. I’m sure it gives people the opportunity to create a variety of intricate machinery. Do many engineers seek the help of metal fabricators to build their designs?

  • Metal fabrication sounds like a fascinating field. I think that the laser cutting sounds the most intriguing. I would really like to learn more about it.

  • I would love to learn how to manufacture sheet metal. I think that would help out with things in my business. I’ve never had to deal with sheet metal until now, so I would very much like to learn.

  • It is amazing that there are custom metal fabrications and forming like this that can create pretty much anything out of this metal. That is a skill that has to be earned and worked for to be able to do. This is a skill that you can not just pick up and be good at. There are a lot of techniques that go into doing everything properly.

  • I didn’t really understand what “forming and drawing” were before I read this article. The more I learn about welding the more I appreciate the hard work and effort that goes into it. I will definitely consider this information before my next big project.

  • I didn’t know that corrosive chemicals could be used to cut metal into its desired shape! I always thought metal fabrication only involved welding, bending and things like that. Does the photochemical milling process produce accurate cuts? Thanks for the great insight into this complicated process.

    • Great question Kyle. Photochemical machining is often called photo-milling and the accuracy of the machining is similar to traditional milling. We can easily maintain size within a few thousands of an inch and geometric controls like parallelism, perpendicularity and profile will be as good as the tool. We can easily hold tight tolerances on those type of tolerances as well.

      Please let us know if there are additional questions.

  • I thought it was cool that lasers are used in cutting metal. I see how that would be the most efficient, but I just think lasers are cool. I think it would be cool to see how this stuff is actually made in person. Thanks for the info!

  • Thanks for the post. I really like the idea of laser cutting. From what I have seen it is very precise and quick. It is also really efficient with material use. It has hardly no limitations with cutting out different types of shapes.

  • Hi Eliza, Laser cutting is not a common process due to the overhead involved in operating the lasers. It requires special training beyond that of a typical machine shop operator.

    Thanks for the question. Feel free to call if you need more info.

  • I’ve always found metal fabrication to be pretty cool. To be honest I have always wanted to see it be done. I find it interesting how a solid object can be manipulated. Laser cutting would be a fun site to see. You mentioned that it’s for highly accurate feature placement, what could one of those features be?

  • I had no idea that there were so many different ways to fabricate metal. I really like the sound of the laser cutting technique. I know that if I needed sheet metal, I would want it to be done as fast as possible. Thanks for the information.

  • One of the things that I like about sheet metal is it’s ability to be made into pretty much anything. If I had to get something cut or made, I would see about getting it done with a laser. Not only is it accurate, but it is consistent if you are having multiple things cut or made. For more intricate pieces, I’d probably see about getting it done by someone with a cutter or welder.

  • Photochemical milling is something I would like to know more about. It sounds almost like a stencil is placed on the metal, then the parts that are exposed are affected by the chemical to bring about the desired effect. I don’t think I understand it correctly, but that’s what it sounds like to me.

    • That’s a good way to think about it. The “stencil” prevents etching the stock and the open sections are etched.
