[The measure to Sink-mark] The measure to Sink-mark on injection molding [by PBT-M Valox DR48] : The use example of Gas-tosu.
Pictures show the change in the flow of air bubble when the molding was done under the following conditions.
Resin: PBT-M Valox DR48
Gas-tosu: Used / Unused
Molding condition: Before improving / After improving
Filling pressure: 110Mpa / 100Mpa
Injection velocity 2: 60mm/s / 30mm/s
Dwelling time 1: 1.0sec / 1.5sec
Dwelling pressure 1: 80Mpa / 65Mpa
Dwelling time 2: 0.5sec / 0sec
Dwelling pressure 2: 75Mpa / 0Mpa
Clamping force: 490KN / 200KN
The sink-mark which had appeared when Gas-tosu was not used yet has been eliminated with using Gas-tosu.
The molding condition by “1 injection velocity & 1 injection pressure” has been realized.
We can propose the Gas-tosu which fits into the present molding condition in your company.
