Intelligent Liquid Foaming Silicone Feeding Machine

Equipment Introduction

The SMART-MIXER-GF96 intelligent liquid foaming silicone feeding machine is engineered for the demanding production of liquid silicone foam. It combines precision metering, automatic ratio control, efficient dynamic mixing, rapid cooling, and continuous stable feeding into a single unit—with one goal: to make silicone foam ratio accuracy and batch consistency stable and repeatable.

Liquid silicone foam is challenging because of the material: high viscosity (up to 400,000 mPa·s), filler content, and heat buildup. Uneven mixing leads to bubbles and unstable foaming. The GF96 addresses this by controlling precision at the metering source, quality through the temperature chain, and efficiency through the mechanical structure:

• Metering source — a 96cc/r high-viscosity screw pump driven directly by an independent high-precision servo motor. The PLC calculates speed commands based on the recipe, achieving fully closed-loop, quantitative, synchronized A/B supply with metering accuracy ≤ ±0.01 (mass ratio).

• Temperature chain — circulating water cooling for key components plus a patented rapid cooling device, with full physical isolation to prevent condensate from contaminating the material, ensuring mixing quality and foaming stability from the source.

• Mechanical structure — funnel-shaped streamlined material tanks + enlarged discharge port (G3.0) + direct connection between the discharge port and pump inlet, reducing pressure loss and clogging risk; a reciprocating automatic dispensing robot enables fully unmanned cycles.

Core Features

• Intelligent control, easy operation: industrial-grade PLC fully automatic control + high-definition color touchscreen (HMI), digital parameter setting, supports 99 recipe storage and one-touch recall—no re-tuning when changing products.

• Efficient temperature control, quality assurance: circulating water cooling for key components + patented rapid cooling device for immediate material cooling; significantly more efficient than traditional double-layer tanks and pump water cooling, with full physical isolation to prevent condensate contamination.

• Precision metering, stable and reliable: 96cc/r high-viscosity screw pump (Taiwan brand) as the core metering unit, driven directly by an independent high-precision servo motor, maintaining ratio accuracy and feeding stability over long continuous runs.

• Continuous pulse-free feeding: continuous, stable, pulse-free supply; maximum output 120 g/s, with a stable common output rate of 50 g/s.

• High-viscosity material compatibility: handles viscosities up to 400,000 mPa·s, designed for filled high-viscosity materials, with excellent screw pump wear resistance and conveying stability.

• Independent dual-tank design: A/B component tanks each 100L (standard configuration, customizable), with independent feeding and no contact between the two tanks.

• Optimized discharge structure: funnel-shaped streamlined tank bottom + enlarged discharge port (G3.0 interface) for smooth flow of high-viscosity materials; direct connection between discharge port and metering pump inlet for simplified piping, reduced pressure loss and clogging risk.

• Efficient dynamic mixing: low-speed dynamic mechanical mixing, with precise control of mixing head motor start/stop and speed, suitable for different viscosities and ensuring homogenization.

• Multi-layer active cooling: a cooling system built from inside out—internal cooling of core components (stirring shaft and blades), external cooling of the mixing chamber (double-layer gun cup structure), anti-condensation insulation (stirring cup, connecting base), with easy-to-clean surface treatment.

• Automatic dispensing module: standard reciprocating automatic dispensing robot, X-axis 1,250mm / Z-axis 200mm automatic travel, Y-axis 500mm manual extended travel for position adjustment.

• Real-time pressure monitoring and interlock: continuous high-frequency monitoring of A/B conveying line pressure, immediate alarm when thresholds are exceeded (indicating pipe blockage or leakage) and automatic shutdown according to preset logic, preventing equipment damage and batch waste.

• Material and temperature monitoring: tank weighing system gives early warning when material is low; temperature control monitors all cooling points in real time, keeping process temperature within ±2℃ of the set value.

• Intelligent fault diagnosis: PLC self-diagnosis, automatic pause on fault with fault code, description and suggested actions displayed in Chinese; automatically records all alarms and shutdown events (including time, code, status), supporting fault analysis and preventive maintenance.

• Tiered access management: multi-level password protection, with different permissions for operators, process engineers, and administrators, preventing unauthorized parameter changes.
