Beginner’s Guide: How to ensure a 100% yield of spout and cap production?

I believe no plastic spout cap manufacturers would be so bold. From past to present, yield inspection has always been a manual process carried out by factory quality inspectors.

Even if their extensive experience allows them to identify product defects in spouts at a glance from every 10 spout and cap, they cannot achieve a 100% inspection rate when faced with tens of thousands, or even hundreds of thousands, or millions of spouts and cap. Reaching 90% is probably the limit; after all, humans are not robots.

Who dares to guarantee a 100% yield for their spout and cap production, or even write a 100% yield directly into their sales contract?

After the spouts are inspected, they are classified into qualified and unqualified products.

If the buyer is a product end manufacturer, in addition to bearing the potential risk of “leaks” at the spout of their finished pouches, it can also cause huge material waste and machine damage due to frequent shutdowns and adjustments of the automatic spout pouch forming/filling/sealing machine they purchased.

So, what does a spout and cap defect rate mean for buyers? Whether the buyer is a flexible packaging manufacturer or a product end manufacturer, this issue causes them a headache.
