Dispensing two-part adhesives to assemble electric vehicles can be a challenge, particularly if the mix ratio is wide or the two components have different viscosities.
Advances in meter-mix technology, process monitoring and bead control are making automated dispensing technology a more viable option for aerospace assembly applications
Adhesives are widely used throughout an aircraft. Jet engines contain structural adhesives, threadlockers, retaining compounds and thread sealants for hydraulic components.
More than 30 suppliers of equipment for dispensing and curing adhesives displayed their latest technologies at the 2016 ASSEMBLY Show. Here is a small sample of what you could find on the show floor.
Two-component adhesives are widely used for assembly in numerous industries, including aerospace, automotive and construction. Applied correctly, these adhesives provide strong, durable bonds.
Comparative claims can be positive or negative, subjective or objective. But, in every instance, their main purpose is illustrative. A common example is when someone claims that a person or process is “as slow as molasses” (which, by the way, has a viscosity of only 5,000 to 10,000 centipoise [cps]).
Manufacturers that use adhesives and sealants to assemble their products know how critical it is for these materials to be dispensed with accuracy and repeatability.
More than 20 suppliers of equipment for dispensing and curing adhesives exhibited at The ASSEMBLY Show last fall. Here is a small sample of the new technologies to be found on the show floor.
Initiating movement of a standard bicycle can sometimes be challenging, such as when peddling up steep hills. Initiating movement of an electric bicycle, on the other hand, has always been much easier. The rider either pedal-assists the motor or activates it with a throttle.
