Industry Background

BYD is a leading company in the new energy vehicle and power battery sectors. Power battery manufacturing places extremely high demands on dispensing volume, mixing accuracy, and process stability for high-viscosity adhesives.

Application Challenges

Power battery packaging and assembly must handle high-viscosity fluids such as thermal conductive adhesives and structural adhesives. Traditional valve bodies often suffer from uneven dispensing, stringing and dripping, and mixing ratio deviations, compromising battery safety and consistency, while also requiring equipment with stepless speed regulation and precise control capabilities.

Solution

SZLKTE provides BYD with a rotary screw dispensing valve (LK‑RS10/LK‑RS20/LK‑RS30/LK‑RS50) solution:

• Equipped with a branded brushless servo motor, offering stepless speed regulation from 0 to 2000 RPM;

• Suitable for adhesives with viscosities ranging from 0 to 100,000 cP, with a minimum dispense volume of 0.075 mL;

• Adjustable reverse suction pressure from -20 to 0 kPa, effectively addressing stringing and dripping issues.

Quantified Value

The servo motor precisely controls adhesive volume and mixing ratios, ensuring stable output of high-viscosity fluids; adjustable suction pressure eliminates stringing and dripping, reducing adhesive waste and rework costs, thereby meeting the stringent requirements of power battery processes for consistency and safety.

Service Assurance

Backed by national high-tech enterprise certification (granted in 2024), we offer free sample testing, remote calibration, and long-term follow-up services to ensure the stable operation of new energy production lines.
