Planetary mixer VK series

verticalcontinuousbatch

Overview
The VK series dental resin vertical kneader is a vertical mixing and kneading machine engineered for processing high‑viscosity dental resins, dental composites and medical polymer compounds under controlled vacuum and temperature conditions.

Key Features

• High‑viscosity mixing: continuous squeezing, shearing and folding action to process thick, high‑solid formulations
• Filler dispersion: dedicated mixing blades to disperse inorganic fillers uniformly and minimize agglomerates
• Vacuum mixing and degassing: sealed vacuum capability to reduce air entrapment and bubbles
• Temperature control option: jacketed heating/cooling shell with external temperature control unit for thermosensitive systems
• Enclosed production: minimizes external contamination and facilitates vacuum processing
• Top-mounted seal isolated from product to reduce contamination risk
• Near‑zero risk of black specks/metal contamination due to sealed design
• No dead zones: superimposed planetary motion ensures homogeneous mixing
• Hydraulic lifting and wall‑scraping for easy cleaning and discharge
• Powerful degassing for very high‑viscosity pastes by thin‑layer shearing plus high vacuum
• Material-contact parts can be stainless steel and mirror‑polished for medical‑grade cleanliness

Materials Suitable

• Dental composite resins
• Dental filling resins
• Light‑cured dental resins
• Temporary restorative materials
• Dental bonding agents
• Medical polymer composites
• Resin‑matrix composites
• High‑viscosity resin and filler systems
