A spin finish, also known as spotting or engine turning, is a mechanical metal decoration technique that creates visually-striking and repetitive circular patterns. The unique interplay of light as it reflects off the finished metal surface adds movement and enhances the aesthetic appeal of the part. Rising to popularity in the 1920s and 1930s, spin finish was frequently seen in the automotive industry, especially on dashboards and instrumentation panels. However, in recent times, this decorative finish has expanded its reach to include a broad range of industries such as aerospace, appliance, electronics, and more.
Our video below provides a look into the spin finish process accomplished at GM Nameplate’s (GMN) Monroe, NC Division. Primarily performed on aluminum or stainless steel, a mechanical spin finish is always applied on a flat sheet of raw metal. The metal sheet is first lubricated with oil to facilitate uniform spinning and prevent burning of the metal when the abrasive pad is applied. The abrasive pads are mounted on single or multiple spindles that descend on the flat surface to skin the metal in a circular, overlapping pattern. The extent to which the patterns overlap each other can be easily adjusted and altered. There are two types of spin finishes that can be applied:
- Drag spin - Once the spindle(s) descends on the metal, it literally drags across the surface while continuously blading the metal and creating overlapping swirls.
- Spot spin - Once the spindle(s) descends, it blades the metal from a targeted spot, ascends, and then descends again on a spot next to it, creating overlapping or isolated patterns.
The computer numerical control (CNC) spin finish machines at GMN can hold up to seven spindles at a time, and the diameter of each spindle can vary from a minimum of 0.5” to a maximum of 20”. The distance between each spindle and the speed at which they travel across the metal surface can be tailored to achieve different looks. Depending on the design intent, the swirling pattern can range from fine, to heavy, to coarse. Spin finishes can also be applied overall or selectively. For selective finishes, a resin is screen-printed on the metal, which protects the desired areas from the abrasive pad, thus creating contrasting looks within the design. Offering a range of sizes, depths, and pattern intensities, the cosmetic variations that spin finish can produce is truly vast.
Once the spin finish is applied, the metal sheet is run through a washing line to remove the oil from its surface. The sheet is cleaned, dried, and a clear or tinted coating is applied to the surface of the metal. As a subtractive process, spin finish takes away the inherent protective layer from the surface of the metal and hence adding a top coat is extremely crucial to seal the exposed metal for performance considerations. The sheets are visually inspected and then are ready to be formed into the desired shape. Decorative accents such as lithographic, screen, digital, and/or pad printing, along with embossed or debossed graphics, are often added to spin finished parts to further accentuate their beauty and allure.
With decades of custom manufacturing experience and printing capabilities under its belt, GMN has worked with several leading companies including Dell, Ford, Callaway, General Motors, Keurig, Fiat Chrysler Automobiles (FCA), and Vaio to create stunning spin-finished nameplates and components. Watch the video below to see the spin finish process in action.

Over-molding is a manufacturing process that combines two different types of plastic together to create a single part. Typically, this involves the use of a hard plastic and a softer plastic (often rubberized). Alternatively, this method can be used to bind two hard plastics together that are different colors. Overall, this is a process that takes various materials with different properties and combines them into a single molded component.
The over-molding process is accomplished through the use of two separate injection molds. To begin, the substrate, which is the first shot (and usually a rigid plastic), is made using the first injection tool. The rigid part is then removed and placed into a separate injection mold tool where the second shot, or over-mold, is molded over the first part. In most cases, mechanical bonds are designed into the part to allow the over-mold to stick to the substrate. These mechanical bonds are formed by creating areas in the substrate (first shot) where the second shot (over-mold) would flow into during the over-molding process.
Over-molding is a value-added technology that is used to provide additional functionality and decoration to parts. It is most often used for its durability for the creation of ruggedized products. It can also be utilized for decoration to provide benefits such as increased aesthetics and functionality. Over-molding can give a product a soft, rubberized feel, making it much more comfortable to handle compared to hard plastic. It also allows for hard edges to be smoothed over and rounded. The main functionality benefit of over-molding is the ruggedized and non-slip surface that it creates, which keeps products safe in extreme environments. Additional benefits include the reduction of unwanted vibrations or noise, increased protection against liquids, and additional brand identity opportunities.
As a technology utilized throughout a variety of industries, such as aerospace, over-molding is an excellent option for customers who are interested in soft-touch handles, grips, etc., or multi-colored buttons, switches, or knobs for their products. Additionally, this process is a great option for sealing or gaskets on parts. Over-molding a gasket on a plastic substrate bonds the gasket material to the substrate, which helps to prevent moisture ingression, as opposed to using a rubber or die-cut gasket that is pressed/held together by screws
Common applications for over-molding within the aerospace industry include aircraft seating, lavatories, stowage bin latches, handles, and user interface switches. Instead of having to create two different parts that then require additional assembly to fasten them together, over-molding allows for multiple parts to be formed into a single part at once. Since the second shot is molded over the first substrate, the bond created between the two is much stronger and more durable, as well as results in a clean design. The key advantages that aerospace applications take away from over-molding include:
- Decreased weight
- Increased strength and durability
- Enhanced industrial design
- Elimination of additional manufacturing and assembly steps
- Reduced manufacturing and assembly time
Since this process involves the use of two separate tools, it is a great method for lower volume programs, but is inefficient for high-volume projects. If you’re looking for a high-volume over-molded part, a better technology to employ would be two-shot molding, which uses a single two-shot mold.

Many industries require the decorative elements of plastic to be highly durable. For example, the aerospace, automotive, and medical industries have many high-wear applications that require strong, durable parts where printed icons won’t scratch off or fade away. Products that are decorated using first-surface decorating processes, where graphics are placed on the outermost layer (such as pad printing, screen printing, or hot stamping), wear out over time and aren’t suitable for these industries. Depending on the materials and processes used, the inks on plastic pieces can fade out over time, making it difficult or impossible to read indicators on those pieces.
In-mold decorating (IMD) is a plastic decorating method that ensures the durability of the graphic overlays and allows for multiple design options for the overlays. In brief, IMD is a process where a graphic overlay is physically fused to injection molded plastic to form one piece. Molten resin is injected either in front or behind the graphic overlay to form a bond between the two. Unlike pad printing, screen printing, or hot stamping – where inks and overlays are exposed to the user that can deteriorate over time – IMD parts have a layer of plastic that encapsulates the ink, protecting it from users and the outside environment.
GM Nameplate’s (GMN) plastics division in Beaverton, OR, Elite Plastics, recently created a video that demonstrates the IMD process. In the video, we see an end-of-arm tool pick up a graphic overlay and place it in the injection mold using a vacuum system, while simultaneously removing a part that was just molded. Both of these functions are completed in one cycle, allowing for faster and more efficient production. Locating pins in both the end-of-arm tool and injection mold itself allow for consistent placement of the overlay in the tool, which is critical for functional parts in regulated industries. If the overlays are not correctly and consistently placed in the mold, some portions of the overlay may not be fully encapsulated by plastic during the molding process.
IMD is ideal for higher volume projects that have stringent durability requirements, as there is more design engineering required up front than with a standard injection molded part. However, one advantage is that once the graphic overlay and molded part is designed, printed graphics on the overlay can be changed at any time to allow for customization and unlimited design options.
