Involvement of a supplier during the conceptual development stage of a product.
Edge
A transition between surfaces.
Edge Bulge
Condition resulting from any forming, piercing, hardware insertion or spot welding operation too close to an edge.
Edge Deckle Mill Edge
Waviness of an unslit coil edge, as received from the material supplier.
Edge Pucker
Material extrusion beyond an outside edge through metal forming.
Edge-to-Feature
A dimension between the edge of the part and a feature.
Effective Case Depth
The perpendicular distance from the surface of a hardened case to the deepest point at which a specified level of hardness is attained.
Electrodes
In gas-metal-arc and gas-tungsten-arc welding, a rod or wire acts as an electrical conductor and arc point between the torch and workpiece. In spot welding, electrodes squeeze together metal parts, then conduct current through to create the weld.
Electrolytically Deposited
Depositing of one material on another commonly known as plating.
Electron Beam Welding EBW
Melting and fusing of metals by use of a collimated stream of electrons traveling at close to the speed of light. The kinetic energy from the electrons converts to heat on impact.
Electroplating
Deposition of a thin layer of metal to a workpiece using an electrolytic process.
Electrostatic Spraying
Method of spray painting in which an electrostatic potential is created between the article and atomized paint particles. The charged particles of paint are attracted to and deposited on the articles being painted.
E-Mail
Electronic mail.
Enclosed Seam and Pocket
Formed, spot welded or welded area that can entrap plating solutions.
End Flare
Seen after cut off, caused by the release of residual forming stresses in material being roll formed, where one longitudinal end springs open and the other springs closed.
Entity
A predefined element that you place in a drawing by means of a single command. A single piece of geometry or text.
Environmental Testing
Testing of a product or finish for resistance to attack by specific elements.
Etching
See Chemical Etching.
Extruded Hole
Pierced and formed hole in sheet metal in which the metal has been stretched creating a tubular shape.
