Dental Resin Vertical Kneader

Dental resin vertical kneader is a high-efficiency mixing system developed by JCT Machinery specifically for dental composite resins, restorative resins, denture resins, and other high-viscosity dental materials.

The equipment features a vertical dual-shaft mixing configuration that utilizes low-speed, high-torque actions—including powerful shearing, extrusion, and folding—to thoroughly blend the resin matrix, inorganic fillers, pigments, and functional additives. It can also be equipped with a vacuum system, a heating/cooling jacket, and a temperature control system to minimize air bubbles during mixing and regulate the material's temperature rise.

For the production of dental materials requiring strict control over homogeneity, viscosity, and air bubbles, this dental resin vertical kneader delivers consistent, stable mixing results across batches.

Why is a professional dental resin vertical kneader needed?

Dental composite resins typically consist of an organic resin matrix and inorganic fillers; some formulations also require the addition of components such as pigments, photoinitiators, and stabilizers. The uniform integration of the fillers with the resin matrix is crucial for the properties of the final material.

In actual production, standard high-speed mixing equipment may face the following challenges:

Difficulty in achieving full circulation of high-viscosity materials
Tendency for powdered fillers to form agglomerates
Air entrapment during the mixing process
Temperature rise in the material due to high-speed shearing
Difficulty in discharging high-viscosity materials
Difficulty in maintaining mixing consistency across different batches

Therefore, the production of dental resins is better suited to specialized mixing equipment featuring forced mixing, vacuum degassing, and temperature control capabilities.
