What’s in a Name? Machine + Template

 Suppose you run a mold in more than one machine. And you use eDART™s to save templates between them, perhaps even just the machine template. Can you use one machine template (volume and injection pressure only) for both machines and get the same parts? Even if the...

Why Cushion?

In response to tip #122 one of our customers asked, “Why bother with cushion when variations in Peak / Shot Volume would show you check-ring leakage and the like?” Well, he was quite right. Variations in the forward motion of the screw can be seen very...

In Decoupled 2 Use First Stage as End of Fill

This is a follow-up to the idea of using templates for machine setup (tip # 87). Here is a convenient method to let the machine tell the eDART where end of machine fill is instead of setting the fill volume on the eDART. In Decoupled 2 processing the end of First...

Setting up Templates by Machine

At RJG we hold that the in-cavity conditions are what control the final part characteristics (plus melt preparation). In instrumented molding we make cavity pressure templates that, if matched, produce the parts closest to the original. In order to keep these...
