A Polish pharmaceutical company is developing inhalation therapy for the treatment of lung disease and the appropriate drug delivery drug. The inhaler has a complex interior and consists of 14 components. In order to be able to produce these with the required precision, Celon Pharma has formed a partnership with the mold making company Glittenberg and its hot runner sister Witosa.

Pipette tips feature a challenging wall thickness/length ratio, an inner geometry that is key for analysis results, and a tip opening just a few tenths of a millimeter wide. They have been in extremely high demand during the coronavirus pandemic, which is why the mold construction and hot runner specialist Männer has developed a mold with an innovative cluster concept.

Once again, the K 2019 in Düsseldorf, Germany, lived up to its claim to be the leading trade show for plastics technology. At least in the field of injection molding, there were exciting global innovations to see – if you looked closely.

Technical Excellence thanks  to Digital Assistance

The new Reverse Cube developed by Foboha manufactures various components or multi-component parts from varying materials in one step and assembles individual parts into finished products independently from the cycle time using an integrated handling robot. The automated process improves quality, accelerates cycle times by up to 40 % compared to separate injection molding and assembly processes, and thus enables substantial productivity gains at lower costs.

The Institute for Plastics Processing (IKV) at RWTH Aachen University is investigating a new control approach for injection molding in which the cavity pressure is controlled by different positions of the hot runner valve pin. The influence on the cavity pressure of different strokes in the holding pressure phase is investigated.

The consumables required for In-vitro diagnostics are manufactured in a production process that is subject to high requirements in terms of precision and quality, but also the complex cleanroom manufacturing environment. This has implications for the entire plant technology – especially toolmaking.

SIAF Guangzhou and Asiamold Conclude Successfully

In the injection molding of engineering plastics, mold temperature control consumes more than one third of the total energy input. A novel technology offers the opportunity to reduce this continuous major cost factor – and eliminate hotspots.

In plastics processing, efficient production methods are required, especially for articles with high volumes and exacting quality requirements, and these must be constantly optimized. The container specialist Walther Faltsysteme has been successfully working together with the Austrian moldmaker Haidlmair for many years.

Well-Balanced Hot Runner Technology for LCP Processing

The Reversecube two-part cube mold is used to produce 60 million multicomponent parts per year on one production line and in the same process. The cycle times must be kept very short while at the same time maintaining stable processes and a high part quality. Sensor-based monitoring and automatic process control is therefore deployed in the form of Fillcontrol from Priamus. It consists of hot-runner balancing, viscosity and compression control as well as automatic holding pressure changeover.

Quality Assurance for Multiple Cavities

The area of application of cube molds has expanded to take in the production of technical parts. The new Allrounder Cube 1800 from Arburg with a clamping force of 1800 kN is providing the response to this trend. With its compact cube, this machine completes the portfolio of products at the lower end of the range.

The aim of the project was clear: a highly automated turnkey system must replace several decentralized, operator-guided machines in order to be able to mass produce enclosures for a vacuum sensor with three inserted pins in a way that is smooth, automated and therefore faster than before in large-scale production, and error-free. The plastics processor Goerlich chose the machine manufacturer Arburg as a partner in its goal of achieving greater production efficiency.

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.”
