Piezoelectric ceramic jet valve uses high-frequency precision piezoelectric ceramic material as the driving force to make the plunger reciprocate up and down quickly to realize high-speed jetting of hot melt adhesive. Due to the fast response speed, high precision and excellent stability of piezoelectric ceramic material, compared with the pneumatic jet valve driven by compressed air, it eliminates the instability caused by air pressure fluctuation, and the stability characteristics of piezoelectric ceramic jet valve are more obvious. This valve body is suitable for: hot melt adhesive jetting of mobile phone frames, TWS Bluetooth headsets, smart bracelets and other high-temperature fluids.
Advantages of hot melt adhesive electric valve:
● High speed: The latest precision piezoelectric driver with ultra-fast dispensing frequency, up to 1500Hz per second.
● Quick debugging: Adopt the latest module design, simplify the debugging method of the plunger, and realize quick top calibration.
● High efficiency: Adopt non-contact dispensing, eliminate Z-axis movement, and effectively improve production efficiency.
● Long service life: Replaceable super hard alloy nozzles and plungers for longer service life.
● Micro dosage: Minimum glue volume 0.5nl, minimum line width 0.25mm, minimum dot diameter 0.2mm.
● Consistency: Equipped with dual constant temperature heating modules, the dispensing consistency of high-speed jet valve can reach ±2%.
● Easy maintenance: Integrated flow channel design, extremely simple all-module heating module components, which can be quickly disassembled and assembled.
● Low cost: Patented design structure requires only a small amount of consumables during maintenance, saving maintenance costs in the production process.
● Stability: Small plunger stroke and large jet force can effectively prevent nozzle glue hanging and scattered points.
