Piezoelectric jet valve heating controller∶ 1. High-power heating device, quickly reach the set temperature, reduce unnecessary waiting time; 2. Built-in imported high-precision temperature control required temperature; 3. It has the function of automatic heat preservation, which can automatically keep heat up when the set temperature is reached, reducing unnecessary operations; 4. It is especially suitable for testing with hot melt adhesive, solid glue and other glues that need to be heated; 5. With piezoelectric jet valve, the nozzle and glue barrel can be heated at the same time to ensure the normal flow of glue 6. The nozzle and the plastic drum control the temperature independently, and the temperature can be adjusted according to the need, which is convenient to operate
