Kunststoffe international, Amorphous Metals Combined with Elastomers
Injection molding manufacturer Engel and technology group Heraeus have succeeded in slashing cycle times in the injection molding of amorphous metals. In so doing, the two system partners have rendered these alloys, which possess special properties, amenable to large-scale production over a wide range of end uses. The K 2019 trade fair will see two-component parts made of amorphous metal and silicone being produced for the first time – inside a fully automated manufacturing cell. Due to their r...

Kunststoffe international, 2005-11-21, Biodegradable Film: For the Sake of the Environment
Packaging For the Sake of the Environment Biodegradable Film. Renewable raw materials are of particular interest for the production of biodegradable plastics if the property profile of conventional plastics can be properly simulated. Films of polylactide copolyester blends and cellulose blends are able to meet this challenge. Initial successes are also becoming apparent in the development of biodegradable self-adhesive tape. During the oil crisis at the beginning of the 1970s, growing environ...

Elastomer Industry Has Understood Elastomers (Trade Fair Report K 2007) The elastomer industry has become ever more heavily dependent on automotive manufacture (approx. 68 % of elastomer products are processed in this sector). Increasing raw material and energy costs associated with spiraling oil prices and growing price pressure due to cheap imports from Asia and Eastern Europe have severely shrunk margins despite continually rising sales. The European, and in particular the German, elastome...

Kunststoffe international, 2008-08-14, Bio – What Else?
Who in the world needs bioplastics? – Obviously not many people still ask this question! Bioplastics have become a permanent factor in the packaging industry (and other sectors), and the demand for it can no longer be satisfied. Companies such as BASF, DSM, DuPont, NatureWorks, Mitsubishi Chemicals etc. are investing heavily in the manufacture of raw biopolymers. The reasons for this unusual market situation were analyzed at the Interpack in Düsseldorf, Germany. Demand Exceeds Supply Acc...

The complete reconstruction of a production system for medical products demands a lot of patience from the participating project leaders. Not just because a thing done well cannot be done quickly, but because the numerous “rules of the game” are sometimes very difficult to combine with practice. The reasons for the greater effort are obvious, primarily the safety of patients who after all expect relief or even cure from a product.“From commencing construction to start-up of production a good thr...

Thermoforming is an inexpensive process for producing parts from thermoplastics both for technical applications and for packaging. An important and often decisive advantage of thermoforming for the respective product is the possibility of manufacturing thin-walled parts using this process. That allows low-weight parts to be produced very rapidly and economically. This advantage is particularly relevant in packaging, but also for large-scale technical parts. Some new features and developments in ...

Polyimide (PI), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN) are typical substrate materials used today for integrated flexible circuits in electronic applications. Hereby, PI film is practically the only material that can be processed in lead-free reflow soldering installations [1], as its excellent thermal properties fulfill one of the most important requirements: it is solder resistant. On the other hand, PI is also a relatively expensive base material for flexible f...

Kunststoffe international, 2011-05-12, Packagings Doing the Balancing Act
Agood half year ago, the K trade show revealed what will probably become more of a certainty at the interpack in May 2011. With the general challenges of globalized economy, packagings increasingly have to do the balancing act between consuming less material and providing enhanced and better functionalities. To satisfy this trend, especially plastics solutions are well-suited: Not only their great benefit – lightweight – but also their ability to protect goods in the long run, make plastics the ...

Kunststoffe international, 2011-08-24, Good for the Environment
The term “bioplastics” is ambiguous and needs to be differentiated with respect to functionality and raw materials base. To begin with, the prefix “bio” can stand for two different properties: “bio-based” and “biodegradable”. A bio-based plastic is one that is generated partly or entirely from renewable resources and can just as likely be biodegradable as it may also be nondegradable. When we speak of “biodegradability”, we mean the capability of the plastic to be transformed into CO2, water and...

Trend predictions are generally wrong and of little use as a rule. This also applies to color predictions: the automotive industry takes its cue from the fashion industry, the furniture industry looks at the automotive industry and the fashion industry searches for that elusive “zeitgeist”. In short, each thinks it has found the ultimate wisdom and propagates its color vision. But in all of this, what always gets forgotten is that the applications being compared are completely different: automot...

Even though bioplastics’ share in the overall plastics market is still quite small, they have established themselves in some sectors. For instance, the production of flexible plastic film for applications such as compostable waste bags or mulch films is commonplace today. The well-aimed enhancement of these materials, especially with regard to their processability, opened up further manufacturing options including thermoforming and injection molding, to bioplastics. Several products have recentl...

It was not until the 1960s that designers discovered the versatile plastic material for their work. They followed the popular trend at that time, paired with a courageous use of color and form. Verner Panton’s legendary cantilever chair of rigid polyurethane foam – the “Panton Chair” (Fig. 1) – went down in furniture history as the best-known representative of this age. The first all-plastic monobloc chair is still popular and trendy with retro-fans even today. First made from acrylonitrile buta...

The dream of every tube and pipe producer of being able to use a simple “rubber head” with which any tube diameter and any wall thickness can be produced without having to stop the extrusion line will almost certainly never be fulfilled. But there are solutions which already come very close to this ideal [1]. The wider the spectrum of the geometries to be produced, however, the more complex and costly the die construction becomes. ...
