Reducing inspection man-hours! Introducing a case where gate clogging was eliminated and short defects were improved.
We introduced Gastose to improve gate clogging in products used for connectors (short prevention). By using Gastose directly under the sprue, we can exhaust gas before it enters the product section, preventing gate clogging during low-pressure molding. As a result, we were able to eliminate gate clogging and improve short defects, while also reducing inspection man-hours. 【Case Study】 ■ Objective: Improvement of gate clogging (short prevention) ■ Molding Information - Size: W25×D5×H9.1mm - Material: 9T Nylon (Genesta G2330 GF33%) - Application: Connector - Number of pieces: 2 - Molding machine: 18 tons ■ Effects - Short defect occurrence rate: 0.48% → 0.002% - Inspection man-hours: 3 sec → 0.5 sec *For more details, please refer to the PDF document or feel free to contact us.
