Mixing Technology
Engineered for Flawless Fluid Dynamics
Two-component adhesives fail when fluid division is incomplete. Inside the tube, fixed spiral elements — no moving parts — split the flow and alternately twist it clockwise, then counter-clockwise, doubling the interleaved layers at every stage (2n, n = element count) for molecular-level homogeneity in a single pass.
[Part A] ──┐
├──► Element 1: Split & Twist CW
[Part B] ──┘
└──► Element 2: Split & Twist CCW
└──► 100% Homogeneous Bead
Layers: 2n · 12 elements = 4,096 interleaved layers
No moving parts — the spirals are fixed in the tube.
Only the fluid turns: clockwise, then counter-clockwise.
Helical Mixing Elements
The standard for laminar flow. Continuous alternating left/right spirals minimise shear-induced temperature rise in heat-sensitive polyurethanes — ideal for general epoxies, silicones and acrylics.
Square Static Mixer (Quadro) Technology
Thorough mixing in a shorter length. The quadro geometry reduces retained fluid volume inside the disposable nozzle by up to 30%, cutting expensive adhesive waste — perfect for robotic cells with limited clearance.
Calibrated Back-Pressure Control
Each nozzle diameter and stepped tip balances fluid velocity against resistance, preventing ratio distortion and cartridge leakage during high-speed automated dispensing.
100% Virgin Engineering Plastics & In-House Injection Molding
Material Purity
100% virgin PP, POM, and PBT ensure chemical inertness against solvents, amines, and isocyanates — no regrind, no contamination, no compatibility surprises.
Burst-Resistant Housings
Reinforced outer walls and uniform wall thickness eliminate expansion and blowout during high-thrust pneumatic dispensing.
Burr-Free Internal Elements
Molded with tooling built in our own CNC/EDM facility. Razor-sharp leading edges divide flow streams cleanly, without microvoids or dead spots that trap cured material.
Leak-Proof Connector Options
Stepped tips, threaded interfaces, and Slip Luer / Luer Lock options for precision needles — a sealed fit on every cartridge system.
Our Factory Strength
Vertically Integrated Production

Frequently Asked Questions
Answers from our application engineering team.
Helical gives gentle, low-shear mixing for most viscosities. Quadro achieves similar efficiency in a shorter length — ideal for robotic arms with limited clearance and for reducing residual waste inside the disposable nozzle by up to 30%.
Backpressure depends on viscosity, inner diameter, and element count. Our engineering team analyses your rheology data to specify the exact nozzle geometry for balanced flow — protecting both mix ratio and cartridge seals.
When viscosity extremes are large (e.g., watery catalyst + thick paste), ratios are extreme (100:1 down to 10:1), or high-shear agitation is needed for fast-reacting foams. The motor-driven rotor ensures a uniform mixture independent of flow rate.
Yes. All our interfaces (A, B, C, F) conform to international standards, ensuring a leak-free fit with both HaiJing and standard 50 ml / 200 ml / 400 ml cartridges.
We provide evaluation sample kits for fit and fluid testing. Once parameters are confirmed, samples are dispatched quickly. Custom tooling and DFM prototypes can also be developed on request.
