Tappet Rod and Nozzle
Tappet Rod and Nozzle are core precision matching components of piezoelectric jet valves and high-speed dispensing valves, as well as key executive parts for micro-volume, high-speed and non-contact jet dispensing. Used in pairs, they jointly complete the whole dispensing process including high-frequency impact, precise glue control, quantitative jetting and instantaneous glue cutoff. They are widely compatible with full-series high-speed piezoelectric dispensing equipment, precision jet dispensers and automatic micro-fluid control systems, and serve as the core accessories that determine dispensing accuracy, jet stability and product yield.
The tappet rod realizes glue extrusion through high-frequency reciprocating impact, while the nozzle completes precise flow limitation, positioning glue output and forming jetting. Working under harsh conditions of long-term high-frequency impact, fluid scouring and medium soaking, the matching components require extremely high standards in material hardness, surface finish, concentricity, wear resistance and fatigue resistance. This series of Tappet Rod and Nozzle are made of imported hard alloy, tungsten steel and precision ground stainless steel substrate with high-end coating technology.
Adopting micron-level precision grinding, mirror polishing, concentricity calibration and anti-stick strengthening treatment, they feature ultra-high hardness, impact resistance, wear resistance, no edge chipping and no deformation. With accurate aperture and smooth inner wall, the products ensure smooth glue output and effectively solve common problems such as hole blockage, glue accumulation, glue hanging, jet divergence and uneven dispensing volume.
With precise matching and uniform clearance, the tappet rod and nozzle are perfectly compatible with various fluids of different viscosities such as UV glue, flux, epoxy resin, AB glue, silica gel, ink and thermal grease. They support multiple precision dispensing processes including micro dot matrix, fine line coating, filling and sealing. Featuring complete specifications and micron-level precision apertures, the products are compatible with most mainstream piezoelectric valves and high-speed jet valves on the market, and support non-standard customization. They meet the requirements of 24-hour uninterrupted high-frequency jetting on assembly lines, effectively improving dispensing consistency and product yield, and greatly reducing equipment operation and maintenance costs as well as consumable replacement costs.
- Ultra-high Hardness & Impact Wear Resistance: Made of hard alloy and tungsten steel with high hardness and strong toughness. It can withstand long-term high-frequency impact and glue scouring at thousands of hertz, avoiding wear, bending and edge chipping for longer service life than ordinary accessories.
- Micron-level Precision Concentricity: Integrally formed by precision grinding with minimal concentricity error. The tappet rod moves smoothly without jamming, and the nozzle has uniform and accurate aperture to ensure consistent glue output in each jetting process.
- Mirror Anti-stick & Anti-blocking Performance: Adopting inner wall mirror polishing and anti-stick coating, the compact and smooth surface avoids glue residue and carbon crystallization. It realizes clean glue cutoff without trailing and prevents hole blockage and glue jamming during long-term operation.
- Wide Compatibility with Fluid Media: Resistant to acid, alkali, corrosion and swelling, it adapts to various industrial glues from low viscosity to medium and high viscosity, covering diverse production process requirements.
- Stable & Controllable Jetting Accuracy: The precise matching gap ensures accurate positioning and concentrated glue output without divergence or deviation, perfectly suitable for high-precision scenarios such as ultra-fine lines, micro dots and narrow edge sealing.
- High Adaptability for Mass Production: Support high-frequency continuous jetting with fast response and stable operation. It adapts to 24-hour uninterrupted mass production on automatic assembly lines, improving quality and efficiency while reducing operation and maintenance costs.
