Mandrels are cylindrical tools
that provide a tight fit when shaping glass or metal. They are typically
machined from hardened steel to hold workpieces firmly. Read on to learn more
about the many uses for mandrels in manufacturing. Listed below are a few. They
are used in jewelry and metalsmithing. Whether you are creating a new ring or
sculpting a piece of glass, mandrels are an essential tool.
Mandrels are Cylindrical Tools
During the manufacturing process, Mandrels are used to guide the material to the right place. Generally, the
mandrel is pulled from a finished composite part. These mandrels are reused,
which can lower the tooling cost, especially in high-volume applications. To
produce the desired shape, engineers must design the tooling with proper
release geometry. Release geometry includes draft angles and male/female
features.
They are Used to Shape Metal or Glass
A mandrel is a tool used for
forming metal or glass into the desired shape. The tool can be made of steel,
aluminum, or composite materials. These mandrels are typically tempered oil
quenched or both. The shapes available range from round to square and
rectangle. Arbors are measured in inches, centimeters, and millimeters.
They Provide a Tight Fit to Hold Workpieces
Mandrels can be used to clamp, insert, or reposition workpieces, and are designed to hold a variety of workpieces. Mandrels have two different designs: an expanding and a fixed mandrel. The latter has longitudinal slots and can be expanded by pressing a tapered plug into them. Mandrels are an essential part of any lathe or milling machine, providing a tight fit to hold workpieces.
They are Machined from Hardened Steel
Usually made of high carbon steel, mandrels are polished to a precise, uniform finish. They are the undisputed leader of the market when it comes to quality, sizing consistency, and precision. Here are some of the benefits of using mandrels:
They are Flanged Tapered or Threaded
A mandrel assembly consists of a
generally cylindrical tube having flanged, tapered, or threaded ends. Each
segment is arranged such that its largest diameter is contiguous with the
forward end of the mandrel assembly. The segments are provided with a radial
surface and an axial bore. An operating means applies axial movement to the rod
means. The result is relative motion between the segment assembly and the
frusto-conical element, causing the segments to hinge and define the taper
mandrel surface.
They are used on a Lathe
A lathe is a machine tool that
cuts metal from a workpiece. The cut is made using a tool that is fixed to a
stationary mounting, called a turret, or computer-controlled motor. These tools
come in a variety of shapes and sizes, including round, square, and diamond.
They are used to make screws, gun barrels, cue sticks, table legs, bowls, and
crankshafts.
They are Made from a Flexible Bladder or Silicone Mandrel
A mandrel with a flexible bladder
is useful for pressurizing the internal parts of a urinary tube. Silicone
rubber sheets with a resistance element molded into them are excellent
candidates. These heaters may also be placed on the outside surfaces of silicone
mandrel segments. They are effective in counteracting the radial outward
pressure on the internal bladder and circumferential pressure on the
interlocking joints. The number of hoop wraps depends on the size of the
mandrel and the load to be counteracted.

They are used to Dig Through Pipes
Mandrels are commonly used to
drill holes in pipe runs and are also used to excavate through pipe wall
linings. They are used to transport materials during excavation and afterward.
The pipes may also house utility lines or power lines. Mandrels are very
versatile and are essential tools for pipelining and excavation. Mandrels are
used in a variety of industrial applications.
