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.

Up to Snuff on Scientific Molding? Then it’s Time to Mold ‘Systematically’
Scientific molding is centered around learning about key molding principles and theories. The strategic application of those principles and theories is what’s known as systematic molding.

Injection Molding: Is There a ‘Most-Important’ Process Parameter?
A case can be made for multiple variables—fill balance, fill time, injection pressure, cavity pressure—as most important. But there is something else altogether that is essential to successful injection molding.

Injection Molding: Fill Based on Volume, Not Weight
Most parts should be 90-99% full after first-stage—by volume not weight. Here’s why that’s important and how to make a first-stage-only part.
