Capabilities

	Bending Capabilities
	Your choices are...
	CNC Bending		CNC bending machines are capable of producing tight radius bends, larger radius bends, and elliptical bends, all on the same part.
	Coiling		Supplier has capabilities to coil tube for heat exchangers and other applications.
	Hydroforming		Hydroforming equipment uses fluid pressure to form tubular ferrous or nonferrous materials to the shape of a die. This processing form allows for severe shape deformation and generally produces strong parts of uniform thickness.
	Hypodermic Gage		There are two different types of stainless steel tubing, hypodermic gage and fractional tubing. Fractional tubing is made to common fractional sizes (such as 1/4" OD) and specified in terms of the outside diameter and wall thickness.  Hypodermic, or needle tubing is specified by gage size, which is determined by the OD and wall thickness of the tube.
	Mandrel / Rotary-draw		In mandrel bending, also called rotary-draw bending, a mandrel is inserted and positioned into the pipe during bending. As the pipe is bent, the mandrel is pulled through the pipe so that the shape is maintained and the bends are not deformed.
	Ram		Ram bending, also called pressure bending, uses a die and hydraulic ram for bending.  The tube is placed in a die and the hydraulic ram, which contains the other half of the die presses into the tube to push it around the radius.
	Roll		Roll bending uses three powered rollers in a triangular arrangement.  The center roller applies downward pressure to bend the tube.  The higher the pressure, the sharper the radius.  Roll bending differs from mandrel bending in that the inside of the tube is not supported.
	Heat Bending		Tube or pipe is heated prior to bending.  In heat-induction pipe bending, an induction coil is placed around the pipe to be bent.  This section of the pipe is heated to temperatures from 800 °F to 2200 °F.  A bending force is then applied to the tube as it slowly passes through the induction coil.  Other heat methods are also used.
	Sand Packing and Hot Slab Forming		Sand packing and hot-slab bending is an old process where the pipe is packed with sand, the ends capped, and the tube or pipe heated. The sand minimizes collapse and ovality of the pipe.  The temperature and method of heating is may vary depending on the material.  The pipe is then removed from the heat source and bent, with one end secured to a bending slab.  A variation of this process is used on PVC as well as steel tubes and pipes.
	Thin Wall Bending		Supplier can bend tubing with a very small wall thickness.
	Other		Other, unlisted bending process.

	Additional Capabilities
	Your choices are...
	Annealing / Heat Treating		Annealing is a heating and cooling operation, usually with a slow cooling cycle.  Annealing may be used to remove stresses, induce softness, and alter ductility, toughness, electrical, magnetic, or other properties.
	Buffing / Polishing		Polishing, buffing, and belting processes are metal smoothing operations that change the surface appearance of the metal. These operations can be for aesthetic and/or functional purposes.
	Cut to Length		Supplier can cut roll formed material to customer specified lengths.
	End Forming		Supplier has capabilities to produce forms on the end of a tube, such as chamfers, flanges, end reduction, end expansion, doming or rounding, beading, and flaring.
	End Flattening		Supplier has capabilities to flatten or bend and flatten the end of the tube.  Many flattening variations can be obtained.
	Machining		Supplier has machining capabilities.  Machining is the removal of material through milling, turning, drilling, and other processes.
	Painting / Powder Coating		Supplier can provide painting to provide a protective and/or decorative coating.  Powder coating is finishing technologies in which dry paint particles are electrostatic ally charged and applied to a smooth surface. Electrostatic attraction holds powder particles on the part surface until heat is added to flow the powder together and cure it. Parts must be electrically conductive. Although powder coating is most widely used on metal parts, recent technological developments have broadened the type of substrates to include glass, special plastics and wood.
	Plating / Coating		Applying a coating, or plating to the surface of a tube or pipe.  Examples of plating and coating options include anodizing, galvanizing, zinc plating, copper plating, and nickel plating.
	Slotting & Notching		Supplier has capabilities to produce slots or notches in a tube or pipe.
	Piercing & Punching		Supplier has capabilities to punch or pierce holes in tube.  The two main styles are dimple hole punching and mandrel hole punching.  In dimple punching, a dimple is created in the tube during the punching operation.  In mandrel punching, a mandrel is placed in the tube during punching to prevent the diameter geometry from being altered.
	Swaging		Swaging forms a tube through a rapid series of hammer blows.  Swaging can be used to point, size, reduce, shape, taper, bond or form metal parts, hot or cold.  It is an economical process that does not produce any chips, improves grain structure and produces a fine finish.
	Telescopic Tube		Supplier has capability to produce telescoping tubes, usually with a spring locking pin or other locking mechanism.
	Welding / Brazing		Supplier has capabilities to perform welding or brazing operations.
	Other		Other, unlisted manufacturing capabilities.
