Product features

The S-Series automatic glue spraying machine with closed-loop flow control delivers precise metering and stable high-pressure output (up to 1000 psi) across tank capacities of 10/20/30 kg and melt rates of 12–35 kg/hr, with selectable high‑precision gear pumps (0.6 / 1.8 / 3.7 cc, single or dual) to handle viscosities from 500–15,000 cps. Its modular structure supports multiple hose/head configurations, powerful heating units (3.5–9.5 kW) and Ni120/PT100 temperature control, providing rapid warm-up, consistent spray patterns and scalable throughput for hygiene, packaging, electronics and furniture applications. Built-in closed-loop flow control and accurate pump dosing minimize waste and ensure repeatable dot/line application, while OEM/ODM customization, CE/ISO certifications, and a one-year warranty with global installation and after-sales support simplify integration and long-term reliability.
