Development of twin-screw mixing extruders. Engineering design of extruding and pelletizing of plastics, undertaking items. Development of pelletizing plants.
Evaporation, concentration, reaction, drying, and powdering of liquid colloid, and wet powder of various polymers.
Tests in plastics dispensation, screw configuration, equipment selection.
Inspection, analysis, dispensation tests, and improvements of high molecular materials.

Domesticated development and design of large-scale extruding pelletizers.
Measuring of plastics machinery and part supply. The processing section of SHJ twin screw extruder is made up of several modular barrel sections which house the two co-rotating screw shafts. Lantai offers various standard barrel designs as well as different conveying and kneading elements. The barrel sections and screw elements can be freely combined so as to get an optimal arrangement matched to a specific process task.
The screws consist of one piece shafts onto which conveying and kneading elements with different effects are installed in any required order. It is thus possible to create different processing zones for Conveying/Pasticizing/Mixing and shearing/Homogenizing/Venting Devolatilizing/Pressure Build-up
