Aluminum Production
From Raw Material to Refined Results
When people think about VKF Renzel, they often think of snap frames, sign holders, poster displays, and retail fixtures. What they may not realize is how much aluminum production goes into those finished products.
Aluminum remains a leading material for poster frames and retail displays because it is lightweight, resists rust and fading, and performs well across both standard and custom builds. At VKF Renzel, decades of experience in aluminum extrusion and fabrication make it possible to produce custom-designed products as well as a wide range of standard items, often in combination with our plastic processing capabilities. Standard products can also be modified to fit specific project requirements.
This flexibility is what makes aluminum so valuable in modern manufacturing. It can serve as the structure behind a poster frame, the support within a retail fixture, the face of a branded panel, or the base for a custom display. What changes from project to project is not just the shape of the aluminum, but the way it is processed. A raw profile or sheet can be extruded, machined, cut, printed, engraved, and coated, depending on the desired end result the customer needs. VKF Renzel offers a range of aluminum services, including profile extrusion, CNC cutting and routing, laser cutting, digital printing, engraving, and powder coating.

Aluminum Profile Extrusion
Aluminum profile extrusion is where many aluminum projects begin. In simple terms, extrusion is the process of shaping heated aluminum by pushing it through a die so it comes out with a specific cross-section. That profile can then be cooled, straightened, and cut to the required lengths for production. The result is a repeatable aluminum shape that becomes the starting point for frames, rails, trim, supports, and many other components. For VKF Renzel, profile extrusion is one of its core aluminum production services.
The real advantage of extrusion is that builds function directly into the profile. Instead of assembling a part from several pieces, you can design grooves, channels, slots, and mounting points into the aluminum from the start. That can simplify production, reduce assembly steps, and create a more refined finished product. In many aluminum projects, extrusion forms the backbone. It gives the part its basic structure and opens the door for additional processing later on.
That function is clear in products like snap frames, slide-in frames, poster rails, and banner systems, where the profile is doing more than just holding shape. It is also creating the track, clamp, or frame structure that makes the product work.

Aluminum Anodizing
Anodizing is an electrochemical finishing process that alters the outer surface of the aluminum into a more stable oxide layer. Instead of sitting on top of the metal like paint, this finish becomes part of the surface itself. That matters because anodizing helps improve the appearance of the aluminum while also increasing its resistance to corrosion, fading, and everyday wear.
Anodizing is a popular choice for aluminum frames, rails, poster hardware, and display components that need a consistent, professional finish. It can also give aluminum its familiar silver or black anodized finish, which shows up across many VKF Renzel products including snap frames, outdoor banner frames and sidewalk signs.
Anodizing is often done early in the process, after extrusion and before later steps. Anodizing helps prepare the aluminum for what comes next while also giving it a finished surface that performs well in real-world applications.

Aluminum CNC Cutting and Routing
Once a profile or panel exists, CNC cutting and routing is often the next step. This is a computer-controlled machining process that uses programmed tool paths to remove material with accuracy. It can create holes, slots, recessed areas, contours, and detailed shapes that would be difficult to produce consistently by hand. CNC cutting and routing is yet another aluminum service that VKF Renzel offers.
What distinguishes CNC machining is its precision control. Because the machine follows a digital design, adjustments can be made quickly without having to rebuild tooling. That makes it a strong fit for one-off custom parts, repeat production, and projects that need tight consistency from piece to piece. For aluminum, CNC cutting and routing is especially useful for panels, brackets, display hardware, fixture parts, and structural elements where fit matters.
In practical terms, CNC machining is what helps move an aluminum project beyond a raw shape. An extruded part may provide the foundation, but CNC cutting and routing gives it its function. It adds the openings, connections, and details that allow the part to assemble correctly and perform as intended in the final product.

Aluminum Laser Cutting
Laser cutting is another valuable aluminum capability, but it serves a different role than CNC routing. Instead of a spinning tool physically removing material, laser cutting uses a focused beam to cut through aluminum with speed and precision. Laser cutting is another service that VKF Renzel offers.
Laser cutting is especially effective for flat aluminum parts with detailed outlines, narrow cut paths, and intricate internal shapes. It is often used when the design calls for precision and part-to-part consistency across multiple pieces. Panels, covers, faceplates, decorative elements, and sign blanks are all good examples of where laser cutting can be useful.
For many projects, laser cutting is the process that defines the part’s outer geometry. It creates the base form quickly and accurately, which can then move into later stages such as engraving, printing, assembly, or coating. When a project depends on detailed shapes and a polished finished appearance, laser cutting often plays a key role.

Digital Printing on Aluminum
Aluminum does not have to remain just a structural material. Digital printing turns it into a communication tool. VKF Renzel specializes in digital printing, which means logos, graphics, product information, and branded messaging can be applied directly to aluminum parts.
Many display and fixture projects need more than structure. They also need visual impact. A printed aluminum panel can act as signage, branding, instruction, decoration, or product identification without requiring a separate overlay or label. Digital printing also gives customers more flexibility. Designs can change from project to project, which makes it well suited to short runs, branded programs, seasonal promotions, and customer-specific graphics.
This is one of the places where aluminum production and product design really come together. A part is no longer just shaped to fit a function. It is also finished to carry a message, reinforce a brand, or add visual character to the final display.

Engraving on Aluminum
Where digital printing adds a visible graphic layer, engraving creates a permanent mark directly in the aluminum surface. Engraving is another part of our aluminum production services.
Engraving is especially useful when information needs to stay with the part over time. Serial numbers, branding, identification marks, nameplates, control panels, and compliance-related details are all common uses. Because the mark is cut into the material itself, engraving is often chosen when permanence matters more than full-color presentation.
It also adds a more finished look to certain products. A precisely engraved logo or line of text can give an aluminum component a stronger sense of identity while still serving a practical role. For projects that need long-term tracking or a more permanent form of branding, engraving is an important part of the process.

Powder Coating for Aluminum Parts
Powder coating is another one of VKF Renzel's aluminum processing capabilities. In this process, a dry powder is applied to the aluminum and then cured under heat to create an even finish. The result is a surface that holds up well against chipping, scratching, and general use, while also giving the part its final appearance.
Powder coating is available in many colors and finish styles, which makes it useful for retail displays, frames, brackets, panels, and custom fabricated parts that need both presentation and performance. It is often the last stage before the part is ready for assembly or shipment, and it plays a major role in how the finished product looks in the field.

Bringing It All Together
Each aluminum service has its own role, but the real value comes from how they come together. A custom aluminum project may begin with profile extrusion to create the base shape of a frame, rail, or structural component. From there, the profile can be anodized to give the surface added protection and its finished appearance. After that, CNC cutting and routing can add holes, pockets, contours, and other machined details, while laser cutting can produce flat parts or intricate panel shapes. Once the fabrication work is complete, the part can be engraved for permanent identification, digitally printed for branding or graphics, or powder coated when a colored finish or additional surface protection is needed.
That kind of in-house range matters, because it gives our experienced manufacturing team more control over the finished result. Instead of treating aluminum as just a raw material, it becomes part of a complete manufacturing path. The end result is a product that is shaped, finished, branded, and prepared for real-world use without the need to split the job across multiple vendors.
