Automation and revamping of PVC compound plants: dosing, turbo mixers, extrusion

Multi Data was founded in 1994 with a clear goal: to bring modern automation to pneumatic conveying and dosing plants for the plastics sector. Our first projects involved conveying calcium carbonate and resin for PVC production. Since then the plastics industry has evolved enormously, and so have we.

Today we are the reference point for those who produce thermoplastic compounds, run PVC extrusion lines or work with technical polymers and need precise, traceable control of every stage of the production process.

What we automate in plastics plants

We work across the entire compound production chain, from raw-material handling to finished-product packaging, through the MultiStore software that manages everything from a single station.

Raw-material conveying and storage

  • Pneumatic conveying of powders and granules (carbonate, PVC resin, mineral fillers, masterbatch)
  • Management of silos, big-bags and unloading stations with level control
  • Automatic distribution to multiple dosing lines

Dosing and mixing

  • Dosing stations for polymers, stabilisers, plasticisers, lubricants and colorants
  • High-precision gravimetric scales for bulk and micro-component dosing
  • Integration with turbo mixers and hot/cold blade mixers
  • Production recipes with configurable parameter and tolerance control

Extrusion line control

  • Supervision of single- and twin-screw extruders with zone temperature management
  • Feeding of gravimetric dosers upstream of the extruders
  • Interface with cutting, winding and palletising systems

Traceability and ERP/MES integration

  • Complete history of every batch: ingredients, actual doses, process parameters, operator
  • Automatic reports by order, shift, item and customer
  • Integration with SAP, Microsoft Dynamics and other ERPs via web service or SQL database

Revamping and retrofitting of PVC plants: what we can do

Many PVC compound plants are still mechanically sound but have outdated automation, panels and PLCs. We bring them back to new without replacing them, with minimal production downtime:

  • Retrofitting of turbo mixers and hot/cold blade mixers — direct control of the whole turbo cycle: speed, duration of each phase, temperature and, above all, when and at what speed to discharge the components. It is the core of our MultiStore software, specific to PVC.
  • Replacement of obsolete electrical panels and PLCs — new panels and replacement of out-of-production PLCs (e.g. Siemens S7-300) with Siemens S7-1500, keeping the existing electronics where possible to contain the investment (step revamping).
  • PLC migration and upgrade — Siemens and Rockwell — with new, safer models and an updated operator interface.
  • ERP integration — recipes, consumption, work plans and batch traceability: a paperless department.

We work on plants of any brand and generation, often concentrating the work in a few days or during the planned shutdown.
