Cycle time reduction

Besides improving your process and the quality of your parts, LaserCusing can also be used to simply shorten cooling times. For example, injection moulding machine suppliers have gone from hydraulic to fully electric machine operation, and from single machine movements to multiple axis movements, but cooling time has remained the same as it was in the 1960's.

Now with LaserCusing, cooling media can be to brought to locations which couldn’t be reached before. We’ve experienced a general reduction in cooling time of 10 to 40%. Even shorter cycle times are possible, and the general dimensional accuracy of parts increases, as well.

The example shown on the right is a HDPE part with a wall thickness of 9 mm and a shot weight of 175 grams:

  • Cycle time with conventional Ampco® core        78 sec.
  • Cycle time with LaserCusing core                      62 sec.
  • Saved time                                                     20%
  • Cost for manufacturing  LaserCusing core          € 3200. = (USD 3800.)
  • Return on investment                                       4 weeks (!)
