Airpress III, a comprehensive patented technology from Ferromatik Milacron, makes gas-assist practical for molding difficult part shapes, while maintaining uniform wall thickness and optimal surface finish.

Milacron has U.S. patents on both the apparatus and the process for applying the gas assist. The process delivers high repeatability with uniform quality to overcome gas-assist defects such as surface finish marred by flow or sink marks and wall thinning or breakthrough.

Airpress III achieves uniform quality by fully filling the cavity with plasticized material, waiting for the melt to cool against mold walls, then applying gas-assist to force out some of the plasticized material and create internal cavities.

Airpress III can be installed on any of the company’s Vista, Maxima, Powerline and Ferromatik families of injection molding machines.
