Loss-in-weight feeder for plastic compounding
Achieve precise material flow and improved production efficiency with an adaptable feeding solution tailored for continuous operation, ensuring optimal integration in complex plastic compounding processes.

Feeds and Weighs Plastics and Granulates
The ProFlex C from Schenck Process is a versatile loss-in-weight feeder designed for the precision dosing of powders and granulates in plastics and masterbatch production. Its unique off-center auger arrangement enables a compact installation, accommodating up to eight feeders in limited spaces. With a feed rate capacity reaching 6000 dm³/hour, the ProFlex C excels in applications requiring continuous and accurate volumetric and gravimetric feeding. The system integrates seamlessly into automated production lines with integrated measuring, control, and regulation electronics. Constructed with vertical container walls and steep wall angles, it ensures optimal material flow and minimizes residue. The ProFlex C is offered in stainless steel configurations for enhanced durability and is compliant with industry standards. Its design allows for rapid disassembly, facilitating easy cleaning and maintenance, making it ideal for environments demanding stringent hygiene and operational flexibility.
