Floform - Leaders in cold forming technology.


	The Cold Forming Process All metals possess the ability to be stretched and formed under applied pressure. This property is known as “ductility”. It is this ability that allows metal to be extruded. Certain metals perform better than others. There is usually a suitable material that will provide the required properties, such as thermal conductivity, or resistance to corrosion. Metals are crystalline in structure and it is this internal structure that allows the “flow” of the metal into the die. Using Finite Element Analysis (FEA) we can model and simulate the flow and behaviour of most metals in the process. The high capacity presses at Floform have been specially commissioned to deliver these loads consistently.











	Forward Extrusion (diagram A) The stock piece or “billet” is pressed into the die by pressure from the punch. The geometries produced range from basic “T” shapes to conical and stepped radius parts. Backward Extrusion (diagram B) The “billet” is extruded through the cavity between the punch and die to create a cup or cylindrical shape. These can be single radius shapes or feature stepped or shouldered radii. Combined Extrusion (diagram C) This is a combination of forwards and backwards extrusion. The billet is extruded and forward formed into the die. Other Variations Floform has orbital motion presses which in addition to the axial pressure applied to the tool, oscillate the punch in order to exert sideways pressure on the material to form other features such as gear teeth or surface notches in the formed part. <<<Benefits of Cold Forming Component Suitability>>>	A Backward Extrusion
