Automatic Viscosity Bulk Mixing Stations
The Arnold Machine Automatic Viscosity-Controlled Bulk Mixing Station is engineered for flexibility and performance. Designed with a modular approach, it supports a wide range of spray application lines and mixing tank configurations.
In automated spray processes, maintaining consistent material viscosity is critical to coating performance, finish quality, and material efficiency. Continuous agitation and closed-loop viscosity control reduce settling, minimize waste, and ensure repeatable results.
Built to meet stringent safety standards, the system provides secure operation when handling hazardous or flammable materials.
Benefits of Automatic Viscosity Bulk Mixing Stations
Consistent Results
Eliminates subjective operator measurements for reliable and accurate viscosity control.
Adaptive Mixing
The system dynamically adjusts the mixing process to achieve the desired viscosity range every time.
Uninterrupted Operation
Mix and adjust viscosity within the cabinet while your coating system continues running without downtime.
How Automatic Viscosity Bulk Mixing Stations Work
The system follows a controlled, closed-loop mixing process to ensure precise viscosity control:
Material Loading: 5-gallon buckets or 55-gallon drums of adhesive and solvent are loaded into the cabinet and connected to integrated fluid transfer pumps.
Ratio-Based Material Transfer: A preset ratio of materials is pumped into a dedicated 20-gallon stainless steel mixing tank.
Agitation & Homogenization: Materials are agitated for a programmed time to create a homogeneous mixture.
Viscosity Measurement: The mixture passes through a viscometer to measure viscosity in real time.
Automatic Adjustment: Based on the programmed setpoint, additional adhesive or solvent is introduced until the desired viscosity range is achieved.
Material Delivery: Properly mixed material is transferred to the spray system or centralized supply line.
COMMON APPLICATIONS
Automatic Viscosity Bulk Mixing Stations are ideal for automated coating operations requiring precise material control and consistent finish quality.
Common use cases include:
- Adhesive-based spray systems requiring tight viscosity tolerances
- Paint and solvent-based coating lines
- High-volume automated spray systems
- Multi-line facilities requiring centralized material mixing
- Operations seeking to reduce waste and eliminate manual ratio measurement
