Case studies - Compound and plastic materials

  • Essai
  • Plan d'accès

The main objectives in the polymer and plastics industry are as follows:
- Unloading and conveying of powders and bulk materials
- Continuous feeding of the extrusion line
- Preparation of the different materials by dosing, heating and premixing
- Installation in an indoor explosive zone called HAZLOC for equipment involving the handling of powders and bulk materials under controlled atmosphere (nitrogen, argon).

The storage of raw materials is generally carried out from stainless steel silos or from  big bags with the integration of explosion protection (explosion vent, specific filters, hopper inerting). Weighed intermediate hoppers provide buffers for feeding the screw feeders. Weighted screw feeders ensure continuous and accurate feeding of the extruder. Pre-mixing lines (turbo-mixing) are installed upstream of the extrusion to ensure the handling and introduction of micro-ingredients. All the storage, deconditioning, conveying, weighing, dosing and control equipment is connected and controlled from the supervision room (PLC, control PC). In addition to the control function, the history (traceability) of the productions is archived. Extrusion is an integral part of the plastic compounding process.
