Hot melt adhesives are extensively used in various industries due to their versatility and efficiency. However, did you know that the size of the hole in the hot melt nozzle can have a significant impact on the amount of adhesive used? Sounds obvious right?
In this blog post, we will explore how selecting the correct nozzle size can result in a 54% reduction in glue consumption, leading to bottom line cost savings and increased productivity. That means, if you are buying say 50,000kg of hot melt a year, just this one tip will drop the amount you buy from 50,000kg to 23,000kg a year, so if you are paying lets say £3.25/kg - this has just saved you £74,750!
We will also discuss the importance of using high-quality adhesives like Generation 6 or Generation 7, which offer numerous benefits over traditional options. Watch the video below to learn more:
The Impact of Nozzle Size on Glue Consumption
When it comes to hot melt adhesives, there is a considerable variation in the amount of glue used depending on the size of the nozzle being used. A small change in nozzle diameter can lead to significant adhesive savings. For example, transitioning from a 0.4mm nozzle to a 0.3mm nozzle can reduce glue usage by an impressive 54%.
By using a smaller nozzle, the adhesive is applied in a more precise and controlled manner. This enables better coverage and minimises wastage, ultimately resulting in substantial cost savings for your operations. It's a simple yet powerful adjustment that can make a significant difference in your adhesive consumption.
The Importance of High-Quality Adhesives
If you drop down in nozzle size, clearly any small bits of char will block the nozzle more easily than a bigger nozzle - so its super important the glue is a non-charring type - we certainly don't recommend doing this change if you use anything less than Generation 5.
Generation 6 or Generation 7 adhesives are non-charring options that offer several advantages over older technologies:
No Degradation: Generation 6 or Generation 7 adhesives are designed to withstand harsh operating conditions, ensuring long-lasting and reliable bonds. They do not degrade over time (even when left on in the glue tank) ensuring long periods of uptime without stopping.
No Stringing/cobwebbing from the nozzle - generation 5+ all exhibit for better cut off from the nozzle without a tail building up.
Lower Operating Temperature: Generation 6 or Generation 7 adhesives operate at just 98 degrees Celsius, compared to higher temperatures required by some conventional adhesives. This not only enhances operator safety but also reduces energy consumption - typically by over 50% when going from 160C to 98C
Choosing the right hot melt nozzle size and using high-quality adhesives are essential steps in reducing adhesive consumption, cutting costs, and improving overall efficiency. By transitioning to a smaller nozzle and employing Generation 6 or Generation 7 adhesives, you can experience significant adhesive savings while enjoying benefits such as no degradation, no charring, and lower operating temperatures.
