Accepted Answer

A: Optional Nordson EcoBead glue-saving pattern generator can save up to 60% of the used glue amount without affecting the adhesion strength.

Question 5

Q: Is the nozzle orifice size the primary factor that affects the glue output amount ?

Accepted Answer

A: No, in the gear pump system, the nozzle orifice size is not the primary factor of the glue output, but the revolution and size of the gear pump are. The nozzle size affects the back pressure in the system.

Question 6

Q: How to maitain the hoses? How to prevent hoses from being blocked?

Accepted Answer

Q：How do I choose the right dispensing valve between pneumatic jetting valve and piezoelectric jetting valve to meet the needs of my dispensing application?

Accepted Answer

A：Nordson EFD has two types of jetting systems. The Liquidyn jet valve series features electro-pneumatic technology, including the P-Dot and P-Jet dispensing valves, and the PICO jet valve series, which includes piezoelectric technology, including the PICO  Pμlse® and PICO Pμlse XP dispensing jet valves. Refer to the BLOG" Pneumatic Dispensing Valves vs Piezoelectric Dispensing Valves" to explain the main differences between pneumatic and piezoelectric jetting technologies, and in which situations to make the best choice.
