Acetal resins, whose chemical name is polyoxymethylene, are formed from the polymerization of formaldehyde. Acetals tend to have a high degree of crystallinity, giving them superior strength and stiffness compared with other thermoplastics, while retaining good toughness at low temperatures. ...
Acrylic resins are widely known for their superior impact resistance and clarity. Acrylates and methacrylates comprise the two main groups of acrylics, which enjoy widespread use in aerospace, automotive and optical applications.
A substance that is added to the raw material used in a process in order to alter some material property. Examples of additives include colorants, flame retardants, and UV protectants. The additives ratio describes the weight of additives that may be added relative to the weight of raw material.
Chemical symbol Al. Element No. 13 on the periodic chart. Aluminum is a white-silver metal with an atomic weight 26.97, a melting point of 660°C (1220 °F), and a boiling point of approximately 2270°C (4118 °F). It is stable against normal atmospheric corrosion, but attacked by both acids and ...
Structures that act as the bottom support for other parts. These include feet, foundations, pedestals, platforms, shelves, stands, structures, supports, trays, etc.
Long, rigid structures that are attached at one or both ends to a surface to provide support. These include arms, axles, bars, columns, cylinders, pillars, poles, posts, rails, rods, shafts, spokes, structures, struts, supports, trusses, etc.
The angle to which a piece of material has been bent. The bend angle can be measured between the bent material and its original position, or as the included angle between perpendicular lines drawn from the bend lines.
A sheet metal bending method in which a V-shaped punch presses a piece of sheet metal into the die opening of a V-die. The die opening is a V-shaped groove in the die plate. The width of this opening divided by the sheet thickness is called the die ratio and typically ranges from 6 to 18.
