High Viscosity 500,000 cps Piezo Jet Valve for Precision Dispensing with 3.55 KG Controller and 125.5×75×20mm Size
Piezoelectric jetting valves are increasingly used in hot melt adhesive dispensing for smartphone/pad middle frame and bezel assembly. These high-precision, non-contact jetting valves provide excellent control over glue volume and placement. For hot melt applications, maintaining stable glue temperature is critical to ensure smooth flow and avoid nozzle clogging or stringing.
Mingseal's hot melt piezo valve system KPS2000-R is specially designed for this process. It includes a dedicated heated glue tank and special seals that maintains adhesive viscosity within optimal range throughout the operation. This enables extended open time, avoiding premature curing and minimizing downtime due to nozzle maintenance.
The solution is ideal for edge sealing, frame bonding, and multi-point glue dispensing on smartphones and tablets, where space is limited and aesthetics are critical. Jetting performance remains stable across high-speed production lines, supporting cycle times as low as milliseconds per dot.
- Non-contact spraying
- High-temperature spraying capability
- High-speed precision dispensing
- Fine glue dot control
- Cost effective and high performance
- Mobile phone middle frame glue dispensing: hot melt glue is applied to the inner edge of the middle frame for bonding glass cover, OLED module or metal backplane.
- PAD middle frame glue dispensing: larger size, longer glue dispensing path, requiring uniform glue spraying and fast speed.
- Multi-point positioning/rib bonding: bonding of local structural parts, such as internal bracket, FPC fixing position, and nut position glue dispensing.
