7L Explosion Proof Tilting Sigma Mixer for BMC

Product Description

Laboratory Sigma Mixer Designed for BMC


Karvil Machinery recently completed the production of a 7L Explosion Proof Sigma Mixer specially designed for a customer in the United States. Built strictly to US electrical standards (480V/60Hz/3-Phase), it integrates a premium Siemens Innomotics explosion-proof motor and a fully compliant Ex-proof control cabinet.The machine is engineered for processing Bulk Molding Compound (BMC), offering safe operation, precise speed control and excellent mixing performance for high-viscosity materials.


The mixer features an explosion-proof electrical system, jacketed mixing chamber, manual tilting discharge and mirror-polished stainless steel contact parts. It is ideal for laboratory research, formulation development and small-batch production where mixing quality and operational safety are critical.

Designed to Solve Common Laboratory Mixing Challenges

Powders cannot be mixed uniformly.

Solution:

Dual Sigma blades continuously fold, stretch and compress materials to achieve highly homogeneous mixing.

Air trapped inside materials affects reaction results.

Solution:

Integrated vacuum system reaches -0.09 MPa to eliminate bubbles and improve reaction stability.

Temperature fluctuates during reactions.

Solution:

Water mold temperature controller provides accurate heating between 35°C and 100°C (customized).

Cleaning is difficult.

Solution:

Mirror-polished SS304 contact surfaces and manual tilting discharge make cleaning fast and convenient.
