Micro Parts
Micro molding presents a unique set of challenges for injection molders. Melt residence time is one of the most important issues in the production of micro molded plastic parts weighing less than 1000 milligrams, especially for parts under 100 mg. The time the melt is exposed to processing temperature and to shear heat while passing through the barrel and the hot runner can be critical to the integrity of the melt.
Mold Hotrunner Solutions® has highly specialized hot runner systems for micro molding and offers the most comprehensive process analysis to guarantee the right melt channel sizing and optimized hot runner design for your micro part.
