Customizable Dental Unit Silicone Rubber Mixer with CNC Machined Aluminum Structure

It's not for large-volume though — the 390mm by 280mm by 380mm footprint keeps it benchtop-friendly but limits batch size to roughly 50ml per cycle or so, depending on viscosity.

We built the frame form magnesium-aluminum alloy with CNC machining rather than casting, so tolerances typically hold within 0.02mm across the mortise and tenon shell joints, and three-bearing positioning system on the stirring rod keeps axial run-out under 0.05mm at both speed settings.

The control board uses a highly integrated circuit with automatic pressure relief built into the 24V line — if a cartridge blocks, it dumps presure rather than rupturing the seal, which we've seen happen on competitors' units when mixing high-thrust silicone for bite registration.

But you get two adjustable speeds via a 4-button interface with one-touch operation basically, and the ultra-quiet design keeps noise below 55 dB even at the high setting; most buyers we deal with find the low speed handles viscosities up to about 300,000 cP better than a standdard 1:1 mixer for this application.

Also, what it does is it's a 5:1 ratio silicone rubber mixer specifically for orthodontic and dental lab work — we usually stock white units, but lead time on custom colors is around 20 days or so (confirm before ordering).
