Frequently asked questions about flow forming, deep drawing, and other topics
Q: How can FlowformingPlus™
reduce the costs of my manufacturing process?
A: Flowforming rarely offers the solution
to all the design requirements of a part or assembly. That is why
we combine flowforming with other complementary, in-house processes,
so that we can meet your design requirements without compromise
on consistent basis. This approach reduces our customer's costs
to further process or assemble our parts.
Q: When is
flowforming and PMF's associated processes more appropriate than
spinning or deep drawing?
A: Flowforming technology creates
parts that exceed the capability of deep drawing or spinning, and
approach the precision of machine parts. Flowforming increases the
strength and wear resistance of the part over spinning or deep drawing.
Flowforming can create parts from tough, difficult to form materials
like stainless steel and Inconel much more easily than using spinning
or deep drawing. Unlike spinning and deep drawing, flow forming
can create parts with controlled changes in wall thickness over
the length of the part, such as parts with heavier bottoms and tops
and thinner side walls.
Q: Is Flowforming
effective for low- or medium-range quantities?
A: Yes. Ideal quantities for production
are up to 50,000 parts.
Q: What if my
part has special requirements that would require design changes
for flowforming to be appropriate?
A: PMF engineers can optimize your
design for flowforming and our related
processes. This optimization often results in a part that eliminates
manufacturing operations at your end and results in a part that
makes your manufacturing process more cost-effective.
Q: Are flowformed
parts expensive?
A: Flowforming is only part of a process
which we follow to help optimize your manufacturing process. We
have often made a company's finished product more cost-effective
by supplying a flowformed part that eliminates quality problems,
secondary operations at your facility and add strength and finishes
that are impossible to achieve with other methods.
Q: Can PMF create
a variety of finishes for my parts?
A: Yes, we can produce commercial
grade satin or brush finishes to mirror finishes, as well as electropolished
finishes in our facility.
Q: What kind
of parts can PMF design and produce?
A: PMF produces hollow, symmetrical,
relatively thin-walled shapes and complete assemblies. Deep cone,
cylinder and contoured parts from stainless and heat resistant steels
and other exotic materials are our specialty. Click

helped engineer and manufacture.
Q: Are flowformed
parts reliable?
A: Flowforming consistently produces
extremely durable products that outperform other components. This
is because the flowforming process tests the quality of the material
and welds. For example, laminations or other imperfections in the
metal structure will cause the material to fail during flowforming.
This is especially beneficial for parts used in stressed applications
such as pressure vessels and aerospace.
Q: How does
PMF achieve such tight part tolerances?
A: Flowforming can control tolerances
within the range of machined parts because of the controlled, intentional
and predetermined reduction of the metal.
Q: PMF sounds
like the kind of company I'd like to work with. How do I get started?
A: You can contact us by phone or
e-mail (information below) or you can fill out this form
and we'll contact you.
