[Cooling time reduction in Sprue bush] PBT/ABS : The use example of Revo-sprue
A picture shows the difference in cooling time under the following conditions by the comparison between the general sprue bush and Revo-sprue.
Resin: ABS
Tapered: 2.5°
The diameter in the tip: Φ2.5
The length of Sprue: 55mm
We had the result, 11 seconds for cooling is necessary to have the temperature which the chucking can be done for the usual sprue bush, but only 5 seconds which is half or less is enough to do the chucking for Revo-sprue.
When same examination was also done for PBT, 6 seconds is necessary for the usual sprue bush, but only 3 seconds is enough for Revo-sprue.
According to the results, the realization of high cycle molding and the reduction of material cost in the volume made by modifying the shape to be star-shaped from the usual shape are possible.
