7L Explosion-Proof Sigma Mixer for BMC Successfully Completed and Ready for Shipment to the USA
Publish Time: 2026-08-05 Origin: Site
At Karvil Machinery, every mixer is built with the customer's application in mind. We are pleased to announce that a 7L Explosion-Proof Sigma Mixer has successfully completed manufacturing, factory testing, and quality inspection. The machine is now ready for shipment to our customer in the United States.
This project was developed for processing Bulk Molding Compound (BMC), a high-viscosity composite material widely used in electrical components, automotive parts, and industrial molding applications. Because BMC requires strong kneading force and precise temperature control, the customer selected a customized sigma mixer designed specifically for laboratory-scale production and formulation testing.
Designed for Safe Mixing of BMC Materials
BMC materials contain fillers, resins, glass fibers, and additives that require intensive mixing to achieve a homogeneous compound. To meet these processing requirements, our engineering team customized this machine with several important features.
The mixer is equipped with:
7L total capacity with 5L working volume
Explosion-proof Siemens Innomotics motor
Explosion-proof electrical control cabinet
Jacketed mixing chamber for heating or cooling
Manual tilting discharge
Variable-speed Sigma blades with forward and reverse rotation
Mirror-polished SS304 product contact parts
Safety interlock lid for operator protection
Every configuration was selected according to the customer's production process and safety requirements.
Factory Testing Before Delivery
Before shipment, the mixer underwent a complete factory acceptance test at Karvil's manufacturing facility.
During the test, our engineers verified:
Stable blade rotation
Variable speed performance
Forward and reverse operation
Explosion-proof electrical system
Tilting discharge mechanism
Mechanical transmission stability
Overall equipment operation
Each machine is carefully inspected to ensure reliable performance before it leaves our factory.
Built to Meet Customer Requirements
This machine was manufactured according to the customer's electrical standard of 480V / 60Hz / 3 Phase, making it ready for installation in the United States without additional electrical modifications.
Our engineering team worked closely with the customer throughout the design and production process to ensure every detail met the application requirements.
This project demonstrates Karvil Machinery's ability to provide customized mixing solutions for different materials, industries, and international standards.
