The Designer's Edge: Hydraulics for Slides, Ejection or Cores
MoldMaking Technology

Randy discusses tips and tricks for avoiding mold downtime when it comes to hydraulics for slides, ejection or cores and hot runner plugs or connections.

Improving Sequential Molding
MoldMaking Technology

For large injection-molded parts, a servo-driven valve gate system can improve surface finish and part performance.

Using Data to Improve Mold Performance
MoldMaking Technology

An easy way to get a snapshot of how a mold is operating is to run regular mold scans via a hot runner temperature controller.

Proving the Advantages of a Servo-Driven Valve Gate System
MoldMaking Technology

One innovation for improving sequential injection molding centers around the use of servomotor technology.New servo-driven valve gate systems incorporate a toggle-type mechanism that operates the valve pin position at 90 degrees from the servomotor stroke.

Hot Runners

Hot runners are the systems in place that deliver the material into the mold to make the part. These systems consist of hot halves, nozzles, gates and temperature controllers—all of which must be monitored, maintained and cleaned for optimal performance and to guarantee a quality end product.
