Extrusion: A Simple Way to Evaluate Extruder Screws
While there’s lots of data that influences screw design, processors usually don’t have access to it. So instead, try calculating drag flow to see if your screw is working properly.

Injection Molding: Process Documentation Is Crucial to Making ‘Identical’ Parts
Use a machine/mold setup sheet to document plastic parameters and use them on any acceptable machine into which the mold is placed.

Automate Injection Molding Simulation With Autonomous Optimization
Simulation not only predicts how a mold will fill, but also provides guidance to make it fill better. The new technology of Autonomous Optimization automatically performs hundreds or thousands of simulations, testing multiple variables—gating, venting and cooling, for example—and learning which combinations help achieve objectives for injection pressure, cycle time, warpage, etc.

Improving Molding Process Capability: Understanding the PVT Graph, Part 1
Process capability is related to the variation in part dimensions from shot to shot. High values of process capability require the shrinkage of the material to be identical on each shot, which can be confirmed from the pressure-volume-temperature (PVT) graph.
