Wood-plastic composites (WPCs) as one of
the promising materials in manufacturing industries are facing rapid
market growth. WPCs are a mixture of thermoplastic or thermosetting
plastics and wood fibers. The extruded profiles of WPCs are widely used
in different market sectors. A promising novel post-production process
to utilize WPC materials may lead to even greater market potential in
the future by creating products with more complex geometries. In this
production process, cutting and forming as the key elements need to be
not only stable but also repeatable. This article evaluates the cutting
repeatability of extrusion-based WPC material, including 45% wood fiber,
50% thermoplastic, and 5% other additives press-formed in a
post-production process. In the studied process, extrusion was selected
as the fabrication method in the production of WPC sheets and the
press-forming method was selected for the post-production process. In
the first stage of experiments, the preliminary cutting process was
conducted using a hydraulic press to find the suitable temperature range
and other production parameters needed in successful production. The
statistical process control chart method was used in the second stage of
the evaluation process. The test results clearly demonstrate that the
selected process has an acceptable cutting repeatability with respect to
the effect of temperature in the cutting process.
