Precision is key

First you try patiently. Then, with mounting irritation, you try harder. You jerk and you tug, but it doesn’t budge. The zipper is stuck. Everyone knows the frustration of a broken zipper in an otherwise flawless item, be it your favorite jeans, boots, tent, bag or suitcase. Ensuring that a zipper does its job perfectly over and over again is a question of quality and therefore a must for any reputable consumer brand.

This is where GF comes in. A zip fastener is produced through a multistage manufacturing process, whereby the interlocking teeth made of either metal or plastic are molded and precisely aligned. Manufacturers of zipper molds around the world rely on GF Machining Solutions’ high-precision wire-cutting EDM machines to cast the parts of zipper sliders. The molds must be extremely accurate and durable to produce in large quantities – as required, for example, by CKK, one of Taiwan’s top zipper manufacturers. All this to ensure that zippers continue to do what they’ve been doing for around 100 years now – make our lives easier.
