Pharmaceutical crimp caps generally consist of a thin aluminum sheet and a plastic component, and are used to seal medical vials, for example for vaccines. Through a combined deep-drawing and backmolding process with previous inline laser treatment of the thin aluminum sheet, the process can be significantly shortened. The media-proof joining together of the two materials is carried out through a mechanically interlocking connection.

A crimp cap for injection vials is manufactured in a two-step process.

Process Reliability Is Crucial

Over past months, many in-house workflows and development processes have slowed down and also changed. Nevertheless, time has not stood still, also not in injection molding technology. The debate and development have been shaped by two themes: digitalization and the circular economy. Below are some examples of developments and projects that underpin this trend.

The Digital Mold Twin

Internal pressure loads are typical for fiber-reinforced plastic components. To increase the burst strength of components, the fiber orientation can be modified in a targeted way during injection molding by means of a rotating mold core. A newly developed simulation method allows this modified fiber orientation to be taken into account at the design stage.

Family molds belong to the state-of-the-art in injection molding – at least when wall thicknesses and volumes of individual components vary considerably. Using a trial mold soon ready for series production, Synventive demonstrates that – though demanding – optimal process control can be achieved using the right technology. The filling of each mold cavity is controlled individually and in real time. The Kunststoffe editorial team were among the first guests at the new Tech Center.

The plastics processor TKW Molding, which specializes in safety-related automotive components, is responding to the increasing requirements of its tier 1 and OEM customers by extensively automating its injection molding production. This also encompasses downstream process steps, such as integrated component testing, traceable part deposition and packaging. The company has been working closely with Arburg in this field since 2020.

Otto Klumpp GmbH has for many years processed, for example, highly transparent PC and high-performance plastics such as PPSU into sophisticated medical products. Since cleanliness and hygiene are essential for implants or blood-carrying systems, injection molding production and parts assembly are performed in the cleanroom. DLC-coated components also play an important role in in-house mold production.

Double Quick-Change System Speeds up Production

Zahoransky Automation & Molds GmbH has entered into a partnership with the Swiss company Kebo AG. The result of this collaboration is a new mold concept for the production of pipette tips, which features a double quick-change system.

Both 8x8 modules on the nozzle side and the cores on the ejector side can be changed in just a few steps to allow production to be resumed immediately when mold cores and wear bushings are replaced. Michael Schmidt, Managing Director Zahoransky Automation & Molds GmbH, comments: “Pipette tip molds are ‘divas’ from a production point of view – very sensitive in the process – and require precise handling: The challenge is that long thin cores are immersed in a counter-bearing and injected on one side. With our new design, all maintenance activities can be completed in a few minutes on the injection molding machine thanks to these quick-change systems on our mold.”

The new 64-cavity pipette tip mold with double quick-change system was developed together with Swiss-based Kebo AG. The company, based in Neuhausen am Rheinfall, has more than 40 years of experience in developing hot runner technology solutions. Says Gerold Keller, owner and CEO of Kebo AG: “We are very pleased with this special partnership between two mold makers who complement each other ideally for this project. As a result, we were able to achieve our common goal in a short development time and improve the technology for manufacturing pipette tips in a way that significantly reduces production costs and significantly improves service life for manufacturing companies.”
