When K 2013 convenes in Düsseldorf, Germany (Oct. 16-23), Braunform (Hall 1/F30) will be demonstrating a 96-cavity injection mold with a 5-second cycle time. Project partners Hekuma and Engel will also be featured.
The 96-cavity Braunform MED mold for a pen stroke (needle holder) is designed specifically for use in cleanroom operations. The high-cavitation injection mold processes the pen strokes using automated manufacturing with constant visual monitoring for quality. With core diameters of only 0.3 mm and 0.5 mm, the tool is a modular design with the modules individually centered and (de)mounted externally accessible.
The mold also features direct side gating with a full hot-runner system from Heitec, and uses conformal cooling to achieve extremely short cycle times utilizing vacuum brazing.
Automation specialist Hekuma developed the high-speed extraction system with an acceleration of up to 17G and a camera visual inspection system ensures automatic sorting of rejects. Machine manufacturer Engel is providing an all-electric e-motion 220-ton press. The mold will be running at Engel (Hall 15/B42).
Another Braunform mold will demonstrated at press manufacturer Ferromatik Milacron GmbH (Hall 15/C06). A 4-cavity injection mold for the production of a single component container, the Adapplicator with a part weight of 1.6g and a cycle time of 9 seconds
The mold’s hot half is used to produce two containers: the 1-ml Adapplicator as well as the 2-ml Adapplicator. The modular construction means that the cavity plate nozzle side and the complete ejector side can be changed while the hot half remains in the injection molding machine. It also allows for replacing the mold inserts on the nozzle side. The mold does not have to be removed from the molding machine during maintenance or cleaning processes.
