Live bottom extruder for processing sealants and mastics
Efficiently integrate entire material batches into your production line while maintaining precise temperature and feed control, eliminating pre-sizing costs and enhancing quality consistency for diverse end-products.

Processes and Loads Sealants and Mastics Efficiently
The RS 6 Series LB and RS 8 Series LB Live Bottom Extruders from The Bonnot Company are engineered to streamline batch processing workflows, tackling the challenge of efficiently handling entire loads of diverse materials—ranging from sealants and mastics to industrial rubber and food products. This equipment stands out with dual-drive technology that independently controls feeding and extrusion, providing unparalleled precision in material handling.
With customized feed beds and multiple temperature zones, including screw temperature control, the Live Bottom Extruder ensures consistent output and optimal material properties. It processes applications such as butyl sealant strips, automotive mastics, and cereal bars, supporting capacities from 1,000 to 4,500 lbs/hour, depending on the model. The extruder’s design incorporates high torque motors and a hydraulic batch loading system for seamless integration into your production line.
The RS Series features jacketed barrels for enhanced temperature regulation, while its flexible configuration—right or left-hand orientation—accommodates various facility layouts. The extruders are suitable for chemical, food, rubber, and sealant industries, offering robust construction with optional material and corrosion-resistant finishes. Simplified maintenance and customizable options ensure these extruders meet specific operational demands and production goals efficiently.
