Understanding—and Using—Decompression to Your Advantage
Decompression—aka suckback—is a very important setting on an injection molding machine. On today’s machines, molders typically get the option to set decompression before and after screw rotation/recovery. Are they using this feature to their advantage?

The 'Butterfly Effect' in Injection Molding—A Connected Process
In injection molding, a seemingly minor change in a setpoint can have a significant impact on part quality and process robustness and repeatability. That’s why Scientific Molding focuses on process outputs, not setpoints.
