Production Process of 7.8mm Silicone One Way Duckbill Valve

The production process for the 7.8mm silicone duckbill valve differs slightly from that of cross slit silicone valves. Given the order quantities, the 7.8mm one-way duckbill valve is produced using compression molding, with subsequent slit cutting and punching performed manually. We utilize imported cutting tools to ensure precise dimensions. After this, the valves undergo a series of tests to guarantee product quality. Prior to shipment, our QC team conducts a thorough inspection, which is why YEJIA is recognized as a leading manufacturer of silicone valves.
