Dispensing is a technology that accurately dispenses colloids in a controlled manner, and plays a very important role in microelectronic packaging technology.

Hot melt adhesives and pressure sensitive adhesives should be preheated before use. When the hot melt adhesive is heated, the temperature must be strictly controlled.

What kind of mechanical equipment is a piezoelectric valve? In daily use, what problems may we encounter? The working principle of the piezoelectric valve today we come to a simple understanding

1. It has self-priming ability and good suction performance.2. Theoretical flow rate only depends on the size and speed of the moving parts.

At the initial moment, the colloid fills the valve body channel, the upper part of the striker is pressed against the bottom of the nozzle and seals the nozzle outlet, the piezoelectric actuator is applied with high frequency, the piezoelectric actuator is extended laterally, and the striker is l...

The colloid enters the thread gap under a constant supply pressure, the motor drives the screw to rotate, and the force generated by the screw rotation causes the colloid to move along the spiral and extrude from the needle. The amount of glue is determined by the nature of the colloid, the param...
