Orbetron News



Orbetron attended and presented information on "Micro Feeding and Blending" in the Pipe/Profile/Tube Breakout session.

This presentation will introduce an expanded concept of micro feeding and blending for both the injection molding and extrusion processes. It will introduce synchronized blending at lower rates to overcome the standard batch mixing process inconsistences. This introduction will also use the same concept with an additional weigh hopper for continuous extrusion operations. The blending systems are designed for throughputs from 100 lbs/hr to 1 lb/hr. These systems are designed to fill a niche market where low rate feeding/blending is critical and a higher accuracy is required. 

Further information, you can contact Orbetron, please go to the contact page and fill in the information and a sales representative will be in contact with you.  


Orbetron was part of the Krauss Maffei 2017 Open House on the 5th of October.

Orbetron supplies blending and feeding equipment for the process of plastic materials into the Krauss Maffei extruders. Orbetron offers a wide array of feeding options that allows Krauss Maffei customers to improve their material usage for both the extrusion and injection molding applications.

Orbetron has developed and improved our technology to offer both our standard single and twin screw feeders while incorporating our disc feeding technology for the feeding of low rate materials such as color, blowing agents, additives and other engineered materials.

All of these benefits go together with the Orbetron O2 controller which is integrated into the Krauss Maffei C6 controller.

For those Krauss Maffei customers that may have older C4 or C5 controllers, Orbetron offers upgrade packages for older Colortronic systems that use the C2 controller. Please give us a call or email us at for further information.

Understanding Low-Rate Feeding for Continuous and Batch Processes


Today in the Tablets & Capsules Solid Dose Digest under More Questions and Answers " How do you microdose API's and excipients? " Orbetron talks about major points and considerations when feeding at very low rates that range between 200 grams/hr and 1 gram/hr.

For the full copy please see paper listed as T&C 


Orbetron presented a paper at Extrusion 2016 "New Frontiers in Low Rate Feeding for Continuous and Batch Processes"

5/18/16 - Orbetron promoted our complete line of feeding equipment, at the Krauss Maffei 50th open house. Shown on the table was our low rate feeders that is capable of feeding 1-500 grams/hour. 

Orbetron, also presented a paper "New Frontiers in Low Rate Feeding for Injection and Extrusion Processes" for the KM attendees. The presentation covered the technology, material issues in feeding low rates, and examples of feeding low rates into both injection and extrusion processes. 


12/31/15- Orbetron has installed one of our 50 Series and 100 Series Disc Feeders in the plastics lab of UMass-Lowell in Lowell, MA. They are using the feeders for feed different powder materials for a small twin screw extruder. Both units are portable and can be used for other applications and processes in their lab.
