German injection mold supplier Braunform will showcase its RotaricE² technology, which achieves time and cost savings by emphasizing process control over quality control, at K 2022 on Oct. 19 to 26 in Düsseldorf, Germany.
The RotaricE² concept integrates several production steps — including assembly — in a small space. The technology will be demonstrated by Arburg (Hall 13, Booth A13-1-B13) on an Allrounder More machine, which will produce a Luer pharmaceutical cap measuring 10 mm in diameter and 11 mm in length.
Notably, the multi-component Braunform side-gate injection mold will combine capping and unscrewing functions. The 4+4 cavity mold serves as a basis for a compact series mold in a modular design with up to 64+64 cavities. Six functions are combined in the ejector side — core-back, two sliders per cavity, lifting of the lid, translational capping of the closures, unscrewing, and final ejection. Modules are individually centered and easily accessible, and the overall design is cleanroom compatible thanks to electric drives, corrosion-resistant steel, low-fat lubrication, and rolling element centering systems. Diffusion-welded inserts facilitate die insert cooling on the nozzle side.
By integrating servo-electric rotary drives in the mold and redirecting rotary movement into translational movement, Braunform achieves compact radial arrangement of injection mold cavities with slides or masking devices around a sprue or, preferably, a side-gate system, the company said.
Ultimately, Braunform claims 45% overall production savings with RotaricE² technology by eliminating the need for two injection molds and machines, as well as an assembly line.
