120,000 cps? No Problem: The Meltax 15L Piston Pump Ends Stringing and Dripping for Good

Not all hot melt adhesives are created equal. High-viscosity formulations – essential for automotive headliners, sound insulation, and durable structural bonds – can bring ordinary gear pump melters to their knees, causing uneven dispensing, poor bonding, and constant maintenance. The Meltax 15L Touch Sensitive 14:1 Piston Pump Hot Melt Adhesive Machine is built specifically to handle these demanding materials.

Guangzhou Keqirui Machinery Equipment Co., Ltd. , a professional hot melt glue machine manufacturer integrating R&D, manufacturing, sales, and service, has equipped the Meltax 15L with a 14:1 pneumatic piston pump operating at a stable working pressure of 4–6kg/cm². This delivers strong pushing power for thick adhesives up to 120,000 cps – a range that ordinary gear pumps simply cannot handle.

Since its founding, Keqirui has focused on delivering quality hot melt machine products that solve real manufacturing challenges. The company's commitment to high-quality product standards and honest business services has garnered praise from customers worldwide. Their business philosophy – sincere cooperation and common development – ensures that every solution is designed to create maximum value for the user.

The results speak for themselves. In an automotive interior component factory case study, the customer used 100,000 cps ultra-high viscosity PO hot melt adhesive for headliner lamination. Their old gear pump machine struggled to deliver thick glue, causing uneven dispensing and poor bonding. After switching to the Meltax 15L with its 14:1 pneumatic piston pump, the stable 4–6 kg/cm² working pressure smoothly transported the high-viscosity adhesive. Uniform coating improved bonding performance, the product defect rate dropped by nearly 20%, and the output met rigorous high and low temperature resistance requirements for auto interiors.

In a handicraft manufacturing case study, the customer needed intermittent dot gluing for small crafts. Their old machine had poor glue cut-off, resulting in stringing and dripping that contaminated workpieces and wasted adhesive. With the Meltax 15L piston pump melter equipped with 2 glue guns and pressure set at 5kg/cm², the pulsed dispensing delivered fast response and clean glue cut-off. Stringing and dripping were eliminated, workpieces stayed clean, and hot melt adhesive consumption was reduced by approximately 10%.

The piston pump's simple structure also brings easy disassembly, cleaning, and low maintenance cost. By adjusting air pressure, operators can quickly change glue flow for different bonding requirements – making the Meltax 15L a highly flexible solution for both intermittent dot and bead spraying applications.
