Plastic Processing Machineries

Currently the following extruded products are considered feasible: flooring, sheets for architectural uses, e.g., office partitions, roofing - corrugated and otherwise, slats for benches and chairs and generally any extruded sections needing mechanical load bearing capacity similar to aforesaid applications.The resulting product has mechanical properties intermediate between General Purpose Polystyrene and HIPS.

Process

Basically, the process involves
  • (1-stage) Compaction of the waste by agglomeration / grinding / shredding followed by extrusion.
  • (2-stage) Dry the granules mix with the bonding/compatibiliser and other additives.
  • (3-stage) Extrusion into final usable shapes.
  • (4-stage) Lamination for decorative finish.

Major pieces of machinery are listed below:

Depending upon the application and type of waste filler or other additives may be added in stage (2-stage) along with bonding/compatibiliser.Use of a compatibilizer and the control of process parameters is the key to the successful operation of the technology. The compatibilizer has also been developed indigenously and this has kept the cost of the whole process low.

Due to the presence of all kinds of inks in the PET/PE film laminate waste available from conversion industry, the final colour of the product from this reprocessed material is likely to be dark (e.g., dark green/grey/black). Some further colour variation may be brought about by the presence of metallized film in the waste.
