AEROSPACE-mixer
In the aerospace industry, material failure is not an option. From the burn rate of solid propellants to the thermal resistance of ablative coatings, product consistency defines success.
Karvil Machinery provides specialized mixing equipment designed for the complex rheology of aerospace materials. We understand that your process involves extreme viscosities (1 million+ cP), strict vacuum requirements, and hazardous environments. Our Double Planetary Mixers and Kneaders are engineered to ensure complete homogeneity, safe temperature control, and scalable results—from the lab to full-scale production. 

 The Karvil Double Planetary Mixer: Engineered for Aerospace

Aerospace materials often exhibit viscosities exceeding 1 million cP or require the mixing of distinct solids into viscous binders. Standard mixers cannot handle this torque. Karvil Machinery  Planetary Mixers utilize distinct blade geometries that rotate on their own axes while orbiting the vessel, ensuring:
Complete Homogeneity: No dead zones in the mixing vessel.
Vacuum Processing: Critical for removing air voids in propellants and composites to ensure structural integrity.
Thermal Management: Precise jacketed heating/cooling to prevent premature curing or overheating of sensitive energetic materials.
Explosion-Proof Design: ATEX/Ex-proof configurations available for hazardous material handling

Mixing Aerospace Materials is Difficult. We Make it Easier.​​​​​​​
Aerospace applications require processing highly viscous materials (often over 1 million cP) with zero defects. Standard mixers often fail to eliminate air bubbles or lack the torque to handle heavy pastes.

Karvil Machinery planetary mixers are designed to solve these specific problems :
Zero Bubbles: High-vacuum design ensures void-free mixtures for flight-critical parts.
Heavy Duty: Powerful motors and gearboxes designed for high-torque applications.
Safety: Explosion-proof options for processing hazardous propellants.
