TECHNOLOGY | MACHINERY TESTING New way to assess surface temperature


Atlas Material Testing Technology has introduced the Atlas S3T system for accelerated artificial and natural weathering testing.


Designed for the flagship Weather- Ometer Ci4400 and Ci5000 instru- ments, it allows continuous measure- ment of the specific surface temperature of individual samples during live testing. Surface temperature drives the rate


of photochemical reactions in weather- ing. To date, says Atlas, measuring surface temperatures has not been feasible for multiple samples in

LED-UV for print curing


Baldwin is showing three of its new printing technologies at the Drupa exhibition, including its Unity LED-UV curing technology. The system reduces power usage by 60% over traditional UV curing methods, it says, having high-powered LEDs and quartz optics for a consistent, complete cure at full press speeds. Its design allows for


greater flexibility with the substrate’s position relative to the cure unit. A compact design enables easy integration into existing press setups. It has the flexibility to switch between LED and conventional UV curing without the need for specialised tools, said the company. � www.bwconvertingsolutions.com

laboratory weathering instruments. This means that surface temperature is often neglected during testing or only roughly estimated based on standard reference temperatures. An integrated, contactless IR


pyrometer sits at the heart of the system, accurately measuring the surface temperature of each speci- men. It and can operate continuously during the complete exposure. Atlas says the system allows for


better reproduction of natural condi- tions, such as heat uptake and colour distribution, as well as better control


SURFACE TREATMENT


Static eliminators raise neutralisation performance


Fraser Anti-Static Tech- niques has launched a new series of static eliminators, which neutralise electric charge on the surface of plastic products. The X-Series claims to


take electrostatic control to a new level, with all products having “in-built reactive intelligence, automatically adjusting the ionisation output of the bar as required”, according to Fraser. The company says that


the X-Series eliminates static more effectively than its previous Neos range of devices. “Our team of engineers has been developing and testing these products so we can deliver exceptional performance to custom- ers,” said James Cater, CEO of Fraser Anti-Static Techniques.

of test parameters to avoid of speci- men overheating. There is also continuous tracing of the specific sample temperature, allowing immediate detection of property changes – such as darkening – without disrupting the test. Investigating specific sample


characteristics – such as activation energies of photochemical degrada- tion reactions for cool pigments, IR-reflective coatings and heat and light stabilisers – is also possible, says the company. � www.atlas-mts.com


The X-Series has a new user interface and visual indication displays showing the operating mode and level of charge detected in real-time. The low-profile footprint means it can deliver powerful static elimination in compact areas.


Electrical connections are identical to existing installa- tions, minimising downtime and allowing for an easy upgrade. There are four models in the range. X-33, the most


powerful, is aimed at long-range static control applications where high- power static neutralisation is needed. X-20 is an ‘all-rounder’ for applications where consistent performance and reliability are needed. X-12L is a medium range, 12kV bar for increased distance static elimination. And X-12F is a short-range


static eliminator, for rapid, close range applications. � www.fraser-antistatic.com
