Peterson Packaging, a Danish printing company, has selected the
Verderflex Dura peristaltic pump to gently handle water-based ink. Transferring ink from storage containers to the rollers on printing machines was proving problematic for Peterson. Air diaphragm pumps were originally responsible for the job, but had proved unable to handle the water-based ink gently enough.
As a result, bubbles formed in the ink, ruining the packaging, creating excess waste and adding expense. To resolve the problem, the company decided to look for a gentle-action pump to ensure bubble-free ink. The chosen design also needed to be both cost effective and sufficiently compact to fit into the limited space available. With the Verderflex Dura peristaltic pump, ink is completely contained within the pump's hose, which is compressed by a rotating roller.
On restitution of the hose, the resulting vacuum draws in more liquid, creating a gentle and accurate pumping process. The design eliminates any danger of cross contamination or spillage. The Verderflex Dura is claimed to provide a 70 per cent smaller footprint than similar pumps. This was an important attribute for Peterson, which required five pumps to fit in a tight space at the end of each print line. As well as overcoming space constraints, the Verderflex Dura pumps are now said to be delivering performance benefits for Peterson.
In addition to transferring bubble-free ink, the pumps are simple to clean and maintain. They can run dry without fear of damage and downtime is reduced as the only wearing part is the hose. Colour change is also quick and simple, according to the company. Peterson has now installed a total of 15 units into its printing process, according to the company's engineering manager.
Digital Surf, the provider of the Mountainsmap surface analysis software, has announced that visitors to its website can request a free surface analysis report based on their own measurement data. The report will give users of 2D and 3D profilometers, optical microscopes and scanning probe microscopes who are not familiar with Mountainsmap the opportunity to get acquainted with its features for visualising measurement data, analysing this data and generating a detailed visual analysis report.

Nihon Superior, a supplier of advanced soldering and brazing materials, has announced that a new presentation about the challenges and issues in lead-free soldering is now available on its website. Copper erosion, voiding and tin whiskers are only a few of the problems in the field of lead-free soldering. Nihon Superior claims that it has has experience with and good knowledge of SN100C, which can reduce bridges with uniform eutectic solidification, provide good through-hole fill and reduce voiding, resulting in low defect manufacturing and high reliability.
