It is virtually pure elemental iron (Fe) that is heated in a furnace before being wrought (worked) with hammers on an anvil. Hammering iron expels most of the slag from the material and bonds the iron particles together. During the […]

The difficulty of manufacturing a part to a specific tolerance can be very material dependent. Generally, the softer a material is, the harder it is to hold a specified tolerance due to the material flexing while cutting. Plastics such as Nylon, HDPE, and PEEK may not hold as tight tolerances as steel or aluminum without special tooling […]
