Due to its high-performing properties polyetheretherketone thermoplastic polymer is being used more and more frequently in many products.

PEEK can replace fluoropolymers in cryogenic applications. Advanced Engineering Valves uses PEEK from Victrex for sealings in ball valves

Delivering Efficiency Even in  Harsh Environments

Styrenics can be polymerized using different technologies and it can be modified with a range of copolymers. The resulting plastics offer a wide range of properties allowing to customize them for different applications. Because of this range of properties they are suitable for many industries. Strong demand is for example driven by the automotive industry, healthcare and the packaging industry.

Styrene copolymers are frequently used in the exterior of vehicles. The Chinese manufacturer Lixiang, for example, uses an ASA for the radiator grill of its electric vehicles

Diverse Shapes and Applications

Lightweight construction, functionality and design are characteristic of material development in all areas of application for PC compounds, composites and films. The range of materials has enormous opportunities when it comes to the mobility of the future, lightweight structural construction with continuous fiber-reinforced composites, 5G technology and medical technology.

In electric vehicles, the original function of the radiator grille, namely to supply air to the engine, is no longer needed. It can therefore be used entirely as a design element, for example by integrating luminous logos and fade-out effects

In the production of plastic parts for the medical and pharmaceutical industry, the requirements for cleanroom environments are becoming increasingly stringent. In this area, not only the demand for all-electric injection molding machines is increasing. There is also an increasing use of electric drives for the implementation of mold movements, which meet the high requirements for cleanliness and reliability.

Arburg Plastic Freeforming is predestined for the additive manufacturing of medtech components. The associated Freeformer-type additive manufacturing systems process the same plastic pellets that are used in injection molding. That makes the open systems very economical to use.

In the AKF process, resorbable original materials such a plate-implants similar to bone, can be manufactured. They are gradually replaced by endogenous tissue

New Possibilities for Use  in the Human Body

Housings not only protect the inner workings of medical equipment, but also protect patients from electric shocks, for example. This function is very important for the increasingly widespread medical wearables, which are often in constant contact with the patient. When designing such devices, it is therefore important to select the appropriate housing material.

Housings play an important role in medical wearables. They protect their inner workings, but at the same time protect the users of the devices

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.

For its complex functional mechanism, the inhaler requires 14 components

Invest in a New Production Line for Meltblown Nonwoven

Thermoplastic compounds with integrated electrical conductivity offer a potential solution to resolve EMI, EMS and electrostatic discharge challenges. These thermoplastic materials can deliver the appropriate level of electromagnetic shielding for electronics, while providing freedom to design complex geometries and opportunities to streamline processing by avoiding secondary operations.

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.

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.

Case Files for Patient Safety

How is a medical device actually made? Six companies will demonstrate a complete production process at the special area, which is professionally supported by the VDMA.

„The production line highlights the interconnection within production and the importance of each individual step in the entire value chain,“ explains Christopher Boss, Executive Director of MedtecLIVE. The manufacturers are not yet revealing what exactly will be produced. Visitors can find out in hourly guided tours during the duration of the medical technology exhibition. However, a look at the companies involved already reveals some details.

The company Forécreu provides the metallic base material for the production line, which is used as the basis for manufacturing. Specifically, it is a cannulated bar material in stainless steel. From this, a workpiece is produced on the Cincom L320–2M12B5 sliding headstock automatic lathe from Citizen Machinery Europe – which can also produce complex parts. The next step is demonstrated by the Gindele company, which has developed an injection mold that overmolds the metal insert with a medical plastic on an Arburg machine. A manual ultrasonic cleaning and passivation system with a final rinsing cascade and hot air dryer from KKS Ultraschall is then used for precleaning.

To ensure that the „medical product“ is traceable, Foba Laser Marking + Engraving demonstrates process-safe UDI laser marking on the production line with the help of the Mosaic camera system, which enables marking without recording. The final cleaning of the component is then again carried out by the KKS Ultraschall system, which is specially designed for cleaning and passivating laser-marked parts. Finally, Medipack packs the component in a prefabricated blister and seals it.

Production will take place on all three days of the exhibition, and a guided tour of the production line will be offered every full hour. MedtecLIVE with T4M will take place from 23 to 25 May 2023 in Nuremberg, Germany. <a href="https://www.medteclive.com/en" target="_blank">www.medteclive.com</a>

How raw material becomes a medical product will be shown at MedtecLIVE with T4M from 23 to 25 May 2023 in Nuremberg.
