The stringing issue that occurs during dispensing is often closely related to fluid properties, equipment parameters, and process settings. Drawing on years of industry experience, Shenzhen SZLKTE has compiled and optimized the following key points for you:

1. Fluid Temperature Control Is Crucial

Appropriate heating can reduce adhesive viscosity and enhance flowability, thereby minimizing stringing. SZLKTE dispensing valves can be equipped with precision temperature control modules to ensure the fluid remains in a stable and consistent operating state.

2. Suction Parameters Must Be Carefully Adjusted

The negative pressure generated during the suction process can effectively interrupt adhesive flow, preventing dripping and stringing. It is recommended to gradually adjust the suction volume and speed according to the adhesive’s viscosity until an ideal balance is achieved.

3. The Distance Between the Nozzle and the Workpiece Must Be Proper

If the distance is too great, trailing is likely to occur; if it is too close, the adhesive bead may collapse. SZLKTE’s needle-type valves are equipped with an adjustable needle mechanism, allowing easy and precise control over dispensing height and adhesive-cutting performance.

4. Dispensing Speed and Air Pressure Must Be Matched

Excessive air supply pressure or excessively slow movement speeds can both increase the risk of stringing. It is recommended to find the optimal combination through segmented adjustments.
