n the aerospace industry, there is no margin for error. Whether you are manufacturing solid rocket propellants, applying fuselage sealants, or developing thermal protection coatings, the material properties must be consistent every single time. A microscopic air bubble or an unmixed clump of hardener can lead to structural weakness or uneven burn rates—consequences that are simply not an option in flight.
For over 20 years, Karvil Machinery has been the silent partner behind successful aerospace projects in over 50 countries. We understand that standard industrial mixers cannot handle the extreme viscosity and strict safety requirements of aerospace applications.
Here is why leading engineers are switching to Karvil Double Planetary Mixers for their mission-critical processes.
Aerospace materials, such as composite resins and solid propellants, often reach viscosities exceeding 1,000,000 centipoise (cP). Standard single-shaft mixers simply push this material around without actually blending it, leaving "dead zones" where ingredients remain unmixed.
The Karvil Solution:
Our Double Planetary Mixers feature two blades that rotate on their own axes while orbiting the vessel. This creates a complex kneading motion that touches every point within the tank.
No Dead Zones: Our precise blade-to-wall clearance (2-3mm) ensures that material is constantly scraped from the walls and moved into the center for intense mixing.
Result: A perfectly homogeneous mix, even for materials that are as thick as semi-solids.

The Karvil Solution:
Mixing under vacuum is standard procedure for us. Karvil mixers are engineered with a robust vacuum seal capable of maintaining -0.098MPa throughout the process.
Active Deaeration: As the blades knead the material, the vacuum pulls trapped air out of the mixture.
Result: A high-density, void-free product ready for immediate application.
Mixing energetic materials (like rocket propellants) generates heat through friction. If the temperature rises uncontrolled, or if there is an electrical spark, the risk is catastrophic.
The Karvil Solution:
We don't just sell machines; we sell safety.
Explosion-Proof Standards: We offer ATEX-compliant / Explosion-proof motors and control panels for hazardous environments.
Temperature Control: Our tanks feature high-efficiency jackets for water or oil cooling. We place temperature sensors directly in contact with the material (not just the tank wall) to give you real-time, accurate readings.

You might know big names like Ross or Myers. Why are engineers in 50+ countries choosing Karvil instead?
Proven Experience: We have focused on planetary mixing technology for two decades. We have seen every viscosity challenge imaginable.
Cost-Efficiency: We offer the same high-spec components (Siemens motors, SKF bearings, Schneider electrics) and rigorous build quality as Western brands, but at a price point that optimizes your ROI.
Scalability: We help you grow. We offer consistent geometry from our 2L lab mixers to our 2,000L production giants. A recipe developed on a Karvil Lab Mixer scales up perfectly to mass production.
Don't risk your project with inadequate equipment. Whether you are setting up a new pilot line or replacing an old mixer, Karvil has the engineering expertise to support you.
