Changzhou Mingseal Robot Technology Co., Ltd.

Customer challenge A leading smartwatch manufacturer in India required a robust inline process to deposit adhesive into small threaded screw holes used to secure bezel and module assemblies. The screws rely on a controlled micro-volume of moisture-curing adhesive inside the threads to prevent loosening while avoiding excess that can foul threads or interfere with assembly. Manual application produced inconsistent glue volumes and occasional thread blockage; variability in bead mass (and hence cure performance) led to rework, slower downstream assembly, and occasional field returns. Technical requirements Target deposit mass: 0.2~0.3 mg per threaded hole. Deposit geometry: contained micro-dot within the thread root (diameter

Product promise Bring panel-level RDL-first FoPLP production in-house with the SS300: a locally developed dispensing platform that combines high-capacity panel handling, multi-head parallel dispensing, and robust anti-warp control to deliver consistent underfill and coating results across up to 600×600 mm panels. Why customers choose the SS300 Large-panel compatibility: Process 510×515 mm and 600×600 mm panels on a single platform. Four independent dispense heads: Simultaneously run underfill, coating, and flux processes to dramatically shorten cycle times. Superior anti-warp control: Mechanical compensation keeps panels flat within ±10 mm through thermal steps—preserving nozzle standoff and dispensing accuracy. End-to-end traceability: Integrated AOI and MES connectivity capture images, recipes, and event logs for full production accountability. Factory-ready automation: Standard PGV/AGV/OHT interfaces make it straightforward to add the SS300 to an automated, lights-out production line. Customer benefits Higher first-pass yields and lower rework from uniform, automated dispensing. Faster throughput using parallel dispense heads without expanding floor space. Reduced dependency on imported equipment with a domestically supported solution. Call to action Validate the SS300 on your materials and panel SKUs with a Mingseal pilot.

Customer scenario A Taiwanese OEM building high-density AI servers required a robust automated solution for applying 2K thermal interface materials (TIMs) and wear-resistant protective coatings on critical core components. The materials included particle-filled thermal greases and silicone-based protective compounds with solid fillers to improve thermal conductivity and mechanical durability. Manual mixing and hand-dispense methods produced uneven coverage, ratio drift, and premature maintenance needs. The customer needed stable A:B ratio control, consistent flow for particle-laden fluids, and long, low-maintenance production runs integrated with gantry and robot assembly cells. Mingseal solution: KDP0350 with robot/gantry integration Mingseal recommended the KDP0350 dual-component auger valve paired with the controller and a compact, replaceable static mixer. The KDP0350 meters A and B using matched eccentric screws and delivers a continuous, homogenous mixed output just before the outlet—ideal for particle-filled TIMs where consistent ratio and shear mixing are critical for thermal performance and long-term component protection. Key process features and implementation Positive-displacement dual‑auger metering: Two synchronized eccentric screws provide volumetric metering that is independent of feed pressure. This ensures the mixing ratio stays within ±3% accuracy across long runs, eliminating weak bonds or incomplete cures caused by ratio drift. Short mixing path and high shear management: The KDP0350 mixes A+B immediately before discharge through a compact mixer element, minimizing residence time and preventing premature gelation. The short path and replaceable mixer design reduce particle settlement and shear degradation of fillers, preserving thermal conductivity and viscosity stability. Wide viscosity and particle compatibility: With a viscosity handling range up to 1,000,000 cPs and ceramic rotors plus FKM/FFKM/EPDM stator options, the KDP0350 reliably meters abrasive, particle-laden TIMs and silicone elastomers while resisting wear and chemical attack. Low pulsation continuous output: Continuous screw drives eliminate pressure pulses common to piston or gear pumps, producing a steady bead or film beneficial for thin, uniform TIM layers on heatsink bases, die attach pads, or spacer interfaces. Robot/gantry-ready and closed-loop control: Integrated with six-axis robots or XYZ gantries, the KDP0350 uses programmable flow profiles (0.7–14 mL/min) and the KSC3000-D controller for recipe-based dispensing. Inline weight verification or laser-thickness AOI can be added for closed-loop mass and coverage confirmation to meet server reliability standards. Production outcomes and value Improved thermal performance and reliability: Consistent A:B ratios and uniform filler dispersion ensured predictable thermal paths and lower junction temperatures in AI accelerators, improving performance under sustained loads. Enhanced wear resistance and longer service intervals: The correctly formulated, uniformly applied protective coatings increased abrasion resistance on moving or contact surfaces, extending maintenance cycles and reducing downtime. Reduced rejects and rework: Accurate metering (±3%) and low-pulsation deposits eliminated under- or over-apply defects and voids in the TIM layer, improving assembly yield and lowering material waste. Scalable, low-maintenance operation: Ceramic rotors and replaceable mixers provide extended life under abrasive fluids, while the short fluid path simplifies cleaning and filter maintenance—supporting continuous production shifts common in server manufacturing. Conclusion  For Taiwanese AI server manufacturers requiring precise 2K TIM and protective-coating application with particle-filled materials, the KDP0350 dual-component auger valve offers a production-grade solution. Its matched-screw metering, short-path mixing, wide viscosity capability, and robot-ready integration deliver repeatable thermal performance, improved mechanical protection, and longer maintenance intervals.
