Yes, automatic silicone dispensing machine can handle different viscosities of silicone materials. Many advanced dispensing systems are designed specifically to work with a broad viscosity range, from low to very high viscosity silicones and related materials.
Key points showing this capability include:
-
Some machines use high-precision gear pumps or piston pumps that can dispense high-viscosity materials continuously and accurately. For example, the PasteFlow 20 system can handle viscosities up to 1,500,000 mPas (millipascal seconds), suitable for thick silicone beads dispensed directly from drums.
-
Certain 2-component silicone dispensing machines are equipped with high-viscosity adhesive material pumps that can feed both low and high viscosity materials. These systems often use ceramic piston pumps combined with pressure monitoring for stable supply and accuracy in metering and mixing.
-
Desktop dispensing systems equipped with advanced valve technology can handle silicone viscosities up to about 100,000 cps (centipoise), covering a wide range of silicone and RTV (room temperature vulcanizing) materials.
-
Manufacturers offer pneumatic, electric, and servo-driven dispensing units capable of handling viscosities from thin silicone oils to thick RTV silicones. Dispensing accuracy and flow rate control are achieved through a selection of pumps, valves, and software controls compatible with different viscosity ranges.
-
The choice of dispensing pump and system depends on the viscosity level: low viscosity (<100 cps) suits manual or low-pressure systems; medium viscosity (100–1,000 cps) fits gear or peristaltic pumps; high viscosity (>1,000 cps) typically needs piston or screw pumps.
Therefore, automatic silicone dispensing machine, especially industrial-grade models, are versatile enough to manage different silicone viscosities, enabling accurate, repeatable dispensing for various production requirements and material characteristics. Choosing the right dispensing technology and system configuration depends on the specific viscosity range and application needs.
