In the manufacturing of Type-C interfaces for mobile phones and computers, achieving the dual goals of “zero air bubbles” and “high efficiency” hinges on the precise coordination of dispensing equipment and processes. The “synchronous twin-screw valve” you mentioned is the core solution to this problem. Simply put, its principle is to multiply efficiency by working synchronously with two-component screw, and to eliminate air bubbles at the source through a precise glue supply and control system.
Below, I’ll break down how it achieves this:
● High Efficiency: Synchronous Work, Doubled Capacity
This is the most intuitive way to achieve high efficiency. The core of the synchronous Two-Component Screw Valves lies in “dual-valve synchronization.”
Double Capacity: Imagine that previously only one dispensing head worked; now, two identical dispensing heads work simultaneously. This is like processing two products at the same time instead of one, directly halving the dispensing time and doubling the capacity.
Intelligent Collaboration: High efficiency is not just about “speed,” but also “accuracy.” The advanced synchronization system can intelligently adjust:
Adapting to Product Deformation: The system can automatically detect potential rotation or tilt of the circuit board and adjust the position of the two valves in real time, ensuring that each valve is aligned with its dispensing position.
Independent Height Adjustment: If the plane heights of the two Type-C interfaces are slightly different, the system can independently adjust the Z-axis height of each valve to ensure that the distance between the dispensing needle and the product surface remains consistent, thus ensuring stable dispensing quality.
●Zero Bubbles: Precise Control, Eliminating Bubbles at the Source
For Type-C waterproof sealing, bubbles are the biggest enemy and must be tolerated with zero tolerance. The synchronous dual-screw valve achieves this through the following design:

High precision Screw valve
Stable Adhesive Supply: The High precision screw valve precisely controls and delivers adhesive by rotating the screw. Compared to traditional pneumatic dispensing, it provides a more continuous, uniform, and highly consistent adhesive volume. This stable, pulsation-free dispensing method is key to preventing air from mixing into the adhesive and creating bubbles at the source.
Precise Adhesive Volume: To ensure that the adhesive volume dispensed by both valves is completely consistent, the system utilizes flow control technology (such as CPJ+ technology from some manufacturers) to automatically correct for changes in adhesive viscosity or minor differences between batches, ensuring the dispensing accuracy and consistency of both valves. This is crucial for maintaining a high yield with zero bubbles.
In summary
the “synchronous Two-Component Screw Valves” solution achieves high efficiency directly through the synchronous operation of the two valves. Furthermore, the precise and stable glue supply of the screw valves and the intelligent control system fundamentally ensure a bubble-free and consistent glue volume during the dispensing process, thus achieving the stringent “zero-bubble” process requirement.
The synchronous twin-screw valve achieves both “zero-bubble and high-efficiency” in the batch dispensing and sealing of Type-C charging and data cables. Its core logic is to solve mechanical air entrapment through volumetric delivery, eliminate reaction bubbles through precise mixing and start-stop control, adapt to batch production capacity with high-frequency stable output and high consistency, and form a closed-loop process from glue supply and dispensing execution to inspection and correction through deep collaboration with the production line system. Essentially, it replaces the extensive output of traditional equipment with precise mechanical control, solving the bubble defect at its source and meeting the core requirements of large-scale Type-C data cable production through improved efficiency and stability. It is currently the optimal technical solution for batch dispensing and sealing scenarios.
