Any continuous profile such as a tube or channel can be an extruded plastic.
Cutting can be done in line during the plastic extrusions process, this depends on
length and thickness. Details such as holes, slots or notches must be done offline.
Avoid multiple enclosures in the plastic extrusions (see drawing with 5 enclosures)
as they are expensive to tool and produce. Be generous with radii in corners
(minimum inside corner .011). Eliminate mass where possible which adds to
material cost and contributes to uneven walls. Uniform walls are key.
The ideal wall thickness for ease of production and cost efficiency is .030 to .080.
Walls as thick as .375 can be extruded but the process is slowed, resulting in
increased labor and material cost. Where strength is critical opt for stiffer
materials which allow for thinner wall thickness.
The more generous the tolerances, the faster the plastic extrusions can run, this results
in cost savings to the customer. Typically a total of .030 is a reasonable tolerance
for efficient line speed, although tighter tolerances can be held. Avoid over
engineering your profile with close tolerances that may not be necessary.
Some materials process easier than others
or run faster than others. Some materials
require more sophisticated dies and after-
