Reducing Startup Scrap in Pipe & Profile Extrusion
Learn how gravimetric extrusion control improves stability, reduces waste, and boosts efficiency.
Startup scrap is one of the most common and overlooked sources of material waste in pipe and profile extrusion. While processors often focus on improving their output rates and maintaining product quality during steady production, significant losses frequently occur before the line even reaches stable operating conditions.
As raw material prices continue to rise and sustainability targets become more important for manufacturers, reducing startup scrap is becoming a priority across the plastics extrusion industry.
What Is Startup Scrap In Extrusion?
Startup scrap is the off-spec product an extrusion line generates between the moment it begins running and the moment it reaches stable, in-specification production. During this time the process is still settling, so dimensions drift outside tolerance and the material must be scrapped or reprocessed.
