Static Extensional Flow Mixer can be attached to any machine capable of pumping molten polymer, such as single-screw or twin-screw extruder, an injection or blow molding machine, gear pump, etc. SEFM is suitable for retrofit on existing production lines. No change is needed for the production equipment.

Specifications

Standard size of SEFM for 1" to 8" single screw or twin screw extruder are available. Custom design will be provided to connect with existing adapter and die. In most cases, SEFM will replace the existing adaptor between extruder and die, or between screen changer and die. No additional space is required. Therefore, there is no need to move blown film die or collapsing frame, etc. EFM Inc. will be glad to answer questions about our products, provide technical assessment on customer's specific mixing problems and provide quotations.

Dynamic Extensional Flow Mixer

The patent pending Dynamic Extensional Flow Mixing Pump (DEFM) can be used to attached to any single-screw or twin-screw extruder. The pump is similar to traditional pump except the inside flow channels promote extensional flow. The pump is not attached to extruder screw and equipped with a motor. The best system for the DEFM pump is our specially designed single screw extruder for mixing. 

Specifications and quotations will be provided upon request.

Screw with Extensional Flow Mixer

Our patent pending embedded EFM in single screw can outperform any other type of mixer in dispersing "unmelt", gel particles, and minor phase polymers with very different melting properties. The EFM will generate minimum pressure drop and the temperature variation through EFM section is trivial.

Specifications and quotations will be provided upon request.
