[Case Study on the Introduction of Gastrose] Improvement of Bubble Defects in the Product Department

Reduction in defect rate and shortened inspection time! A case study of reducing defects using gas vents and air vents.

Due to the occurrence of bubble defects in the product section used for connectors, we implemented gas vents and air vents to reduce defects. After implementation, the gas vent effect allowed for the discharge of gas and resin in front of the product section, preventing mold contamination and extending maintenance intervals. Additionally, low-pressure molding became possible, enabling stable production quality. 【Case Study】 ■ Objective: Improvement of bubble defects in the product section ■ Molding Information - Size: W16×D15×H14mm - Material: PBT (Juranex) - Application: Connector (mainly for home appliances) - Number of pieces: 4 - Molding machine: 50 tons ■ Effects - Bubble defect occurrence rate: 0.50% → 0% - PL surface cleaning interval: 6H → Not required - Disassembly cleaning interval: 4 days → 8 days - Inspection time per piece: 3 seconds → 0.2 seconds *For more details, please refer to the PDF document or feel free to contact us.
