Durability of Mathomat templates
Pictured in this video is a Mathomat V2 template undergoing stress testing on our test machine. The new large format Mathomat templates will be available from June 2021, and we will be able to release comparative durability numbers for the whole range around the end of June.
Mathomat V2 durability
The Mathomat V2 template has averaged around 55,000 cycles on our test machine before developing breaks in the plastic between shapes. We plan to use a durability score of n/50,000 for reporting on the strength of the various templates in the Mathomat range, where n = the number of cycles on the test machine before a breakage occurs.
Mathomat V3,V4,V5 and V6 durability
Taking a score of 1.1 for Mathomat V2 durability as a baseline we expect that the new large format templates will have significantly higher scores since their larger format affords greater space between template shapes.
Mathomat V7 durability
The Mathomat V7 template will be an exception, because the type of plastic used in this product will not be as durable. We are actually not sure what score the Mathomat V7 will achieve, but we hope for something better than 0.7.
Please report breakages
If your template develops a crack in the plastic between its shapes please report this to us. Doing this helps us to rearrange the design of the Mathomat so it has exactly the same functions as before but with a shape distribution that achieves greater durability. If we agree that your Mathomat should have lasted longer then we will send you a free replacement.
Heat resistance of magnets on the Mathomat white board templates
Some schools in Western Australia have reported difficulty with the magnetic clamping of the Mathomat white board templates. When left attached to school whiteboards over the weekend, in summer, when the school air conditioning is switched off the glue holding the magnets to the template has softened and allowed the magnets to slip out of place and the whiteboard to detach.
We are testing a new glue which has a high resistance to heat. Our yardstick is that our next production batch of Mathomat whiteboards should be able to stay attached when the temperature is 60 degrees centigrade. We will be conducting laboratory tests on the new adhesive in June and will report on results then. In the meantime we recommend that in hot climates the current Mathomat WB-1 and WB-2 templates not be left attached to whiteboards overnight.
