Stability and dimensional accuracy of the mixing tube structure: Avoiding dispensing deviation and process failure

The structural stability and dimensional accuracy of the mixing tube directly affect the dispensing positioning accuracy and assembly compatibility:

Structural stability of the blade: If the internal blades of the mixing tube are not firmly fixed and prone to loosening, during high-pressure dispensing, the blades may shift or break, disrupting the "separation - convergence" mixing process and causing a significant drop in mixing effect; high-quality mixing tubes are produced through an integrated injection molding process, ensuring a tight connection between the blades and the tube body, which can withstand 0.8-1.2 MPa of dispensing pressure without deformation.

Interface dimensional accuracy: The dimensional deviation of the interface between the mixing tube and the dispensing valve, needle, etc. (such as the outer diameter tolerance exceeding ±0.1mm) will cause leakage at the connection point, which not only leads to waste of glue but also contaminates the surface of the workpiece, increasing the subsequent cleaning costs; high-precision interface design (such as using ISO standard interfaces) can achieve seamless connection, eliminating the problem of leakage.

Control of mixing tube residue: Reducing cost loss and process contamination risks

The performance of the glue residue of the mixing tube directly affects the production cost and the cleanliness of the process during glue replacement:

The impact of excessive residue: Ordinary mixing tubes due to insufficient smoothness of the tube wall and excessive blade gap, will result in 5%-10% of glue remaining in the tube, for high-value glues (such as conductive silver glue used in semiconductor packaging), it will cause significant cost waste; at the same time, if the residual glue is not thoroughly cleaned, when changing different types of glues, it will cause cross-contamination of new and old glues, affecting the dispensing quality.

Advantages of low-residue design: Using inner wall polishing treatment and optimized blade gap, low-residue mixing tubes can control the glue residue to be below 2%, not only reducing material loss but also reducing the cleaning steps during glue replacement, improving production efficiency, especially suitable for multi-variety and small-batch dispensing scenarios.
