Birchwood Technologies offers free sample finishing of iron, steel, or aluminum parts to demonstrate the quality and feasibility of their finishing processes.
Prospective customers can send between 5 to 10 unfinished parts along with the sample request form and Birchwood Technologies will process the parts in their lab. They then provide complete process details and return the finished parts.
Widely used on many types of tooling and machine components, the TRU TEMP low temperature black oxide process forms a durable, black magnetite finish that complies with
Mil-DTL-13924 Class One, and withstands up to 100 of salt spray when sealed with an appropriate rust preventive. The non-polluting, low temperature process is much safer and simpler to operate than the boiling 290° black oxide. Finish appearance and corrosion protection is equal to or better than the high temp method. TRU TEMP part finishing takes just 25 minutes using a simple dip-tank process, and can be installed in any production plant with factory training.
Ideal for precision machined components, the LUMICLAD® electroless black oxide process forms a smooth, durable black finish that is .000060 inches thick (1.5 micron). This process provides a high quality method for blackening aluminum that doesn’t involve the complexities and high costs of electrolytic black anodizing. The LUMICLAD finish will not shrink hole diameters or add measurable thickness to critical surfaces. In addition, the finish is electrically conductive, which makes it an ideal material for applications requiring a chassis ground. Rinse waters for the process are easily purified and recycled by means of an ion exchange system, so nothing enters the drain. LUMICLAD part finishing takes just 30 minutes for most aluminum alloys using a simple dip-tank process.
Test Finishing Iron and Steel Parts with Aluminum Oxide and Zinc Phosphate
These processes are great for parts that don't require a black finish, but need a protective grey coating. “This part testing offer is the best way to evaluate the feasibility and quality of our TRU TEMP, LUMICLAD, and other metal finishing options, at No Charge,” reports Jesse Vouk, Sales and Marketing Manager of Birchwood Technologies. “Our finishing experts will turn the sample parts around with recommendations within one week.”
