The modified skin packaging process helps prevent product rejects and therefore cuts back on the raw material waste. It also saves material in the skin film application process when compared with converting polyethylene, the material used in an early development stage. Both the skin film and its production residue can be recycled in the polyethylene waste stream.
Because of its chemical structure, Surlyn is melt-stable and tough, even when heated, Ulrich Zappe, managing director of Zappe Verpackungsmaschinen, said in the press release. "This is particularly important for three-dimensional components, as it enables very high draw ratios without the risk of the film tearing at the edges."
The material's good heat absorption makes the film stretchable after only 10 seconds of heating, instead of the 15 seconds required for polyethylene, when working with the company's SKVA-5050 3D skin-packaging machine. This saves process energy and reduces cycle times, Zappe said. "This is particularly important when the machine -- as is the case at the Miele plant in Warendorf -- is an integral part of the overall production process, and is required to fit a specific cycle rate."
This is a very interesting example of a new process bring better "functionality" to a process while being more efficient. It requires less heating time (less energy) and the material can easily be recycled. A great example of design engnieering improvements that help everyone.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
