Plastics Engineering Tools
Free calculators and reference charts for engineers who print, coat, bond and laser-mark plastics. Built on Sabreen's 30+ years of plastics surface-engineering work.
Surface Energy & Dyne Level Calculator
Will your ink or adhesive wet the part? Check the dyne margin, convert contact angles to surface energy (Owens-Wendt) and look up typical values for 20 plastics.
Open the tool →Adhesion Failure Troubleshooter
A bond, print or coating let go. Answer five questions and get the likely causes ranked - surface energy, contamination, migration, cure and more - with the checks that confirm each.
Open the tool →Laser Marking Plastics Chart
Fiber, UV or CO2? See how 21 plastics respond to each laser, whether you get a dark or light mark, and when the resin needs a laser-marking additive.
Open the tool →Why we built these
Most printing, coating, bonding and marking problems on plastic parts start with questions these tools answer in a minute. Is the surface energy high enough? Why did it let go? Will this resin take a laser mark? They are free, work on a phone on the production floor, and need no sign-up.
They are also a starting point. When the numbers say a process should work and it still does not, that is the kind of problem Sabreen's engineering services exist to solve.
