Injection molding enters a whole new world when done at the micro-level. We tell our customers, some of the largest tech companies in the world, that micro molding is equal part art form as it is a manufacturing process.

Byal recently wrote a piece published in Design World’s niche publication Make Parts Fast on the challenges that come from gate design and gate drag.


Tips on working with gates in micro-molded parts

As technology shrinks, previously overlooked aspects of injection molded parts are causing significant challenges and problems. With larger injection molded parts, the gate, where polymer enters the mold cavity, only represents a small percentage of surface area. In micro-molding however, the gate becomes a part feature, whether you like it or not. There’s a simple fix…
