Aluminum comprises roughly 1/12 of the earth’s crust, but is never found as an elemental material. Bauxite ore is mined and chemically refined into alumina, which is a white powdery material that can then be electrically separated into molten aluminum ingot and carbon dioxide. Four pounds of basset are required to produce each pound of aluminum. Recycling saves 95% of the energy needed to produce aluminum from bauxite ore, and currently between 85 and 90% of aluminum is recycled.

Aluminum is then processed into billet and different elements like silicon, manganese and copper are added to create alloys. Different combinations enhance properties such as strength and hardness. Aluminum can then be cast, spun or extruded.

Extruding aluminum has been compared to squeezing toothpaste from a tube where the paste takes the shape of the tube opening. An aluminum billet, heated to approximately 900 degrees F, is placed in the extrusion press and forced under pressure through a steel die. The die determines the desired finished cross section. Extrusions are desirable because they are strong, resilient heat and electrically conductive, nontoxic, reflective, nonsparking and nonmagnetic. They also respond well to bending, stamping, cutting and punching. Roughly 20% of total aluminum consumption in the United States is in the form of extrusions.

MuNiMulA relies on extrusions for its line of products. The process of fabrication beings with the design and fabrication of a custom die which matches our design specifications. Billet is forced through these dies at an extrusion plant as described above. The billet we use contains 60% scrap aluminum, with 55% being post industrial scrap and 5% post consumer materials. From herewith fabrication takes place at our facility, cutting, machining, drilling, and welding to achieve a finished product. We use both MIG and TIG welding depending on the application.

Once the product is completed it is ready to be finished. MuNiMulA finishes all of our products by anodizing. This insures a durable protective finish that does not compromise the nature and feel of the metal Anodizing may be clear or in a range of colors.

MuNiMulA anodizing and finishes are performed by following the European Union directives from July 1 2006 on a greener environment. Therefore we adopted the Restriction of Hazardous Substances Directive, 2002/95/EC, commonly referred to as RoHS. Our partners in the process of anodizing and finishing some of MuNiMulA's products adhere to this directive and restrict six materials used in the manufacturing of various types of electronic and electrical equipment. This directive is closely linked to the Waste Electrical and Electronic Equipment Directive, (WEEE), 2002/96/EC. WEEE focuses on collection, recycling and recovery targets for electrical goods. RoHS also restricts the use of lead, mercury, cadmium, chromium VI, Polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). MuNiMulA adopted these EU Directives, which are not law, and is up to each EU member state to adopt and enforce.
