Micro dispensing integrated solutions have long posed technical hurdles, especially when processing intricate contoured workpieces — such as laying precise sealing beads on electronic housing shells and performing structural adhesive bonding for compact precision components. Our volumetric Micro Screw Dispensing Valve (Micro Feeding Screw Valve) delivers a reliable, high-performance solution to resolve all such micro dispensing challenges.
Custom-engineered for continuous uniform deposition of pasty adhesives, sealants, thermal gap fillers and potting compounds, this auger metering dispensing head adopts a low-shear working principle. It enables ultra-gentle, low-pulsation material feeding ideal for shear-sensitive formulations and high-viscosity media without damaging adhesive properties or generating air voids.
Boasting remarkable process flexibility, the micro screw valve supports variable-volume micro dispensing and conformal coating across a wide range of miniature workpieces. Compatible with self-leveling adhesive supply systems, vacuum pressure plate pump feeding stations and bubble-free feeding systems, it seamlessly matches dynamic mixing heads, two-component AB epoxy dispensing units and compact in-line vacuum potting equipment.
Engineered for uninterrupted mass production, the valve minimizes equipment downtime and cuts routine maintenance expenses, effectively lowering total operational costs for manufacturers. It is extensively deployed for PCB encapsulation, tiny ECU & sensor potting, power semiconductor encapsulation, flat wire micro stator dripping coating, FIPG formed-in-place sealing and lithium battery miniature component sealing in new energy vehicle, consumer electronics and automotive electronics production lines, paired with compact multi-layer curing ovens for complete automated micro dispensing workflows.The integrated solution for micro dispensing is a big challenge for micro dispensing due to the complex geometric shape of the workpiece - for example, when applying sealing beads to the component casing or adhesive during the bonding process. Our volumetric screw metering valve will be a great solution for this situation. They are designed specifically for the continuous application of pasty adhesives, sealants, and sealing materials. Due to its working principle, it allows for very gentle and low pulsation feeding of shear sensitive and high viscosity media. In addition, these systems provide a high degree of flexibility in handling variable amounts of glue or applying glue to different workpieces. Customers can also benefit from the shortest downtime and low maintenance costs, thereby reducing overall operating costs.
