Flow Analysis Gets It Right the First Time
This molder's trial parts showed visible flaws that made them unusable. Simple changes in tooling, processing, or materials couldn't fix it. But flow simulation provided an answer that worked right off the bat.

Unscrewing Molds Go Electric
Hydraulics are the usual power source driving unscrewing cores to separate threaded parts from injection tools.

Molding Simulation Gets Easier Than Ever
In the mid-'90s, when Peter Rucinski worked for a plastics resin supplier, he broke his company's record by performing 30 mold simulations in one year.

Secrets of Successful Thin-Wall Molding
Demands to create smaller, lighter parts have made thin-wall molding one of the most sought after capabilities for an injection molder.
Read MoreDetermining Maximum Mold Cycle Counts
The first production meeting with my new employer went something like this: “We want you to establish a preventive maintenance program that is based on cycle counts for all our molds.” Before I could launch into an explanation of how best to determine maximum cycle counts, I was hit with this: “So, how many cycles do you think our molds can safely run before we need to clean them?”Leaving my crystal ball at home and unable to get my x-ray vision working, there was no way to answer that question with any accuracy.
