Everything You Need to Know About Metal Shop Services with Prototek

Metal fabrication typically involves multiple processes to achieve a finished product. As a metal shop, we offer multiple services under one roof, making it much easier to complete a customized metal fabrication. Regardless of if you only have an initial design or are ready to start production, our metal shop services can help you.

Our Custom Metal Shop Services

Metal fabrication is very versatile because there are many metal shop services that can be used to meet any number of needs. Our metal shop services include the following:

  • Laser Cutting and Punching

    In laser cutting, the laser beam melts material to cut sheet metal and high-pressure nitrogen blows the molten metal out of the kerf. The laser cutting head is moved over the metal plate in the shape of the required part on a CNC laser cutter, cutting the part out of the plate.

    Punching removes scrap metal from a raw metal sheet. A punch press is used to squeeze a tool through a sheet of raw metal.

  • Material Graining

    As a metal shop, we use graining to achieve a consistent surface polish by grinding metal components with a belt grinder.

  • Drilling, Countersinking and Tapping

    Drilling makes a fully cylindrical hole with a smooth interior surface without using heat or mechanical strains on the hole’s surface. Thread tapping is more durable than welding and creates a thread that allows for a bolted connection. Countersinking removes sharp edges from the hole, creating a smoother finish.

  • Forming and Bending

    Our metal forming procedures involve applying force to a sheet of metal to change its geometry rather than removing any material. Bending is a metal forming technique that involves applying a force to a sheet of metal, causing it to bend at an angle and form the required shape.

  • Hardware Insertion

    PEM nuts, standoffs and studs are among the components that can be installed using hardware insertion as part of our metal shop services.

  • Mechanical Assembly

    This describes the process of assembling metal components as part of our metal shop services, as well as the end result.

  • TIG, MIG, Spot Welding and Weld Grinding

    Welding is a metal shop service where sheets of metal are joined using heat, pressure, or both while they cool. TIG welding gives the smoothest result, while MIG is fastest.

    Spot welding uses an electric current to impart pressure and heat to the weld zone to join two pieces in one spot.

    In our metal shop services, weld grinding completes the process of welding by removing extra materials.

  • Welded Assemblies and Frames

    As a metal shop, we can offer full welded assemblies and frames, which can be customized to your needs.

Our Metal Shop Finishing Services

Finishing is an important aspect of metal fabrication, because it can improve durability and help with the aesthetic results. We offer a number of different metal shop finishing services, each of which has different strengths and weaknesses.

  • Powder Coating

    With powder coating, the coating is applied as a dry powder using an electrostatic process and then cured with heat as a finishing process.

  • Painting

    Painting is a great alternative for metal projects that involve heat-sensitive materials and tasks that don’t require a lot of durability. We can offer more colors with paint than other finishes.

  • Chemical Agent Resistant Coating

    One of the several metal shop finishing services that we offer includes Chemical Agent Resistant Coating, which is a form of paint that is used to protect military vehicles against chemical and biological weapons.

  • Silk Screening

    Silk-screening involves using thin polyester mesh and a squeegee or blade to apply paint on a specific area of metal.

  • Laser Engraving

    Laser engraving can add a design or an identifying mark on a project after completion.

  • Chem Film

    Chem film is a corrosion-resistant chemical conversion coating for aluminum sheet metal.

  • Anodizing

    Anodizing is an electrochemical process where aluminum is immersed in a liquid bath and an electric current is passed through it. This process thickens the oxide layer on the aluminum’s surface.

  • Black Oxide

    Black Oxide turns the surface of a ferrous substance black and adds durability by chemically changing it.

  • Bead Blasting

    We use bead blasting to give a sheet metal project a more consistent finish by firing a round spherical substance against the surface.

  • Tumbling

    Tumble finishing is a method of smoothing and polishing a rough surface on small parts made of sheet metal.

Our metal shop services are a great choice because we can offer a wide range of custom metal fabrication services. Contact us today to learn more about our metal shop services and start your custom project.
