Some of the value added services that we at Ardel provide include:

Anodizing MIL-A-8625

Ardel Engineering and Manufacturing is capable of the following types of anodic coatings: Type I Class 1 (chromic acid anodizing – non-dyed), Type I Class 2 (chromic acid anodizing – dyed), Type II Class 1 (sulfuric acid anodizing – non-dyed), Type II Class 2 (sulfuric acid anodizing – dyed), Type III Class 1 (hard anodize – non-dyed), and Type III Class 2 (hard anodize – dyed). These specifications are only used for military and aerospace products and can ensure corrosion resistance, fatigue resistance, and outstanding pain adhesion.

MIL-DTL-5541 (also known as MIL-C-5541) Chemical Filming

MIL-DTL-5541 Type I chemical film, refers to the use of hexavalent chromium. The coloring of this film usually appears to be gold or brown in color, but can be clear. MIL-DTL-5541 Type II chemical film refers to using components containing no hexavalent chromium. This is typically clear in color. Utilizing MIL-DTL-5541 chemical film can ensure maximum protection again corrosion, whether painted or unpainted, and where low electrical resistance is required.


Our grinding capabilities include centerless, contour, taper, and wet grinding, just to name a few. In centerless grinding, the outer diameter of a part is ground without restraining the workpiece. When set up correctly, centerless grinding can be used to not only refine the surface finish, but improve the roundness of a part at the outer diameter.

Complex grinding processes, such as contour grinding and taper grinding, can be used to finish numerous types of low volume projects such as prototypes, fixtures, and tooling. We can provide surface finishes on the level of 0-2 RMS on complex parts, and on more than one occasion have astonished customers with the quality of workmanship we are able to provide.


Our honing capabilities include honing of tubes, blocks, molds, or complex shapes, made of various metals, plastics, ceramics, or composite materials. During the honing process, honing stones are used to abrade the part surface, removing imperfections and creating a smoother, flatter surface. In the case of cylindrical components, honing processes can be used to create a truer surface, improving the roundness of the inner diameter. The characteristic cross-hatch pattern left on the metal surface after honing is also very desirable for retaining fluid-based lubricants in mechanical applications. Due to the simplicity of the tooling and ability of the tool to improve the roundness of the part, there are many instances in which honing is a faster and more accurate option than ID grinding or hard turning processes.

Various Secondary Processes Available

However, Anodizing MIL-A-8625, MIL-DTL-5541 (also known as MIL-C-5541) Chemical Filming, Grinding, and Honing are not the only value added services Ardel Engineering & Manufacturing can provide. We are also capable of performing many other processes, such as: passivation, heat treating, electroplating, drilling, tapping, laser cutting, and waterjet cutting, and many more.
