RADIAL
AND ORBITAL FORMING TECHNOLOGIES
Radial Forming, Orbital Forming Tools, Forming
Tools
Radial
and orbital forming machines by Baltec manufacture
assembly equipment products with superior joint
strength, superior finish, and virtually no grain
distortion.
Radial and orbital forming are cold-forming techniques.
Cold-forming is where the piece is not heated
before it is in the forming machine. Both
radial and orbital forming can be used on any material
that
can be
done in
this cold forming process.
The reason for this forming technique is that
unlike other processes, radial forming uniformly
displaces
material in
three
directions by kneading microscopic amounts of
material radially outward, radially inward and
tangentially overlapping.
Radial Forming
and Its Advantages
The radial forming process was developed in
Europe in the mid 1960s, and since has been
adapted for various applications.
Radial Forming is often paired with orbital forming.
Even though the two forming processes share similarities
they also have major distinctions. Radial forming
is unique. It displaces material uniformly at
a constant speed, in an eleven-sided rosette
pattern to ensure uniform and consistent material
displacement. The radial forming process results
in higher joint strength and superior surface
finish.

Look
at the Radial Forming Rossette Pattern:
At center,
minimum material is displaced. As distance from
the center
increases,
so does
material
displacement.
This uneven rate of material flow leads to inconsistent
flow patterns.
Radial
Forming Technology:
- Supporting forming fixtures can be simpler
and less expensive because side loads are minimal
to non-existent.
- Radial forming reduces friction between tool
and rivet leads for substantially longer tool
life.
- Radial forming tools do not spin, creating safer workstations.
- Simple and inexpensive riveting tools can easily
be made in most forming machine shops.
- Our tool holder and pressure cup design eliminates the need for thrust bearings.
Radial forming is highly versatile in its ability
to form ferrous and non-ferrous metals, die cast
materials and case-hardened fasteners. The metal
forming machines can be set to precise pressures,
thus it has been used successfully in conjunction
with assemblies containing Bakelite, ceramics,
glass, and other brittle materials. Radial forming
tools facilitates riveting of precision parts,
precious metals and various thermoplastics. You
can also engrave, mark, coin and burnish surfaces.
Orbital Forming
Orbital forming and fastening combines both pressure
and orbital motion to accurately form and fasten
parts. The orbital forming technique fabricates
heads on rivets, posts and pins. The metal form
tool is held at a slight angle. As the peen tool
moves in an orbital path, material is displaced
with each rotation of the forming head until forming
is complete. Due to the moving line of pressure
during the orbital forming process, a solid rivet
will have a smooth finish in contrast to a galled
or hammered finish.
Your Benefit
in Using Radial and Orbital Forming Techniques
At the end of the day, Baltec is the only riveting
manufacturer that can offer both technologies for
all riveting applications. This assembly process
is used to efficiently produce appliances, hinges,
latches, locks and other automotive parts. This
translates into optimum assembly machine performance,
while maximizing the cost of ownership for your
automated assembly equipment.
