  2. 6 implementation steps 1.Testing Eko Saveto show its capability in saving money. It is recommended to compare it with the competitors’ materials. 2.Training operators and management to work correctly & systematically. 3.Setting a list of rules- When should clients use Eko Save and how much they should use in each case 4.Working with the users on availability of Eko Save products to the operators. It is recommended to use a bucket marked with quantities. 5. A consistent checking systemover achievements and irregular problems. 6.Nominating a responsible operator/manager

  3. FAQ FREQUENTLY ASKED QUESTIONS What is Purging? purging is an essential part of the cleaning process. Done properly, purging should: • Effectively displace the resident resin. • Eliminate the resident resin in dead spots or negative flow areas. • Remove heat sensitive resins, additives and pigments which are susceptible to degradation. • Eliminate black specks produced by carbon build-up

  4. WHEN SHOULD YOU PURGE? • Changeover: the changeover between jobs, since purging will remove previous colors, resins and carbon build-up that could contaminate future production • Shutdown and Startup: are sources of degradation caused by exposure of resin to excessive heat. • Routine Preventive Maintenance: purging can help extend the operating life of plastic processing machinery. • There is no necessity to purge between easy colors on short production runs.

  5. The basic way of using EKO-SAVE The full procedures of use are in ourweb-site… • To use EKO SAVE purge in a continuous cleaning routine when changing colors & materials & not as a method for putting out fires. • Clean the color dozer, hoper & throat well, raise the temperatures at the end of the cylinder, die & head by 20°c. • Empty all the remaining materiel from the cylinder & fill the machine with EKO SAVE (1.5 volume of the cylinder + die + head). • Let the EKO SAVE purge stand in the machine for 10 minutes, check to see that the material is slowly flowing out of the die or mould. • Push the EKO SAVE purge out at a speed alternating between 20-50% of working speeds. If the machine is still not clean - return to stage number 3.

  6. the big problems in Extrusion cleaning The most problematic areas for cleaning are: flat dies, blow molding heads, blow film dies & adaptors. Certain materials & colors may also be problematic, but with the correct resin & by carefully following the Eko purge instruction you can resolve all these problems.

  7. Problems of purging in Injection Molding? The problematic areas are usually the end of the screw, the nozzle & the hot runner. Problematic materials & colors can be a cause for problems; for example a machine which works with a number of different polymer resins can [cause] host degraded polymer which will be the cause for burnt degraded resin. The correct EKO-purge with the appropriate instructions will solve these problems.

  8. How long can I leave "Eko Save" in the barrel? • We recommend you follow the purging procedures, but extended residence time will not harm the equipment, or decrease the effectiveness of EKO SAVE.

  9. Is EKO SAVE safe for people? • Yes. All active ingredients are completely non-toxic and have been approved by the Food and Drug Administration (FDA) for use with food and the REACH standard as well.

  10. Is EKO SAVE safe for hot runner systems? • Yes. Our products can be processed through gates & hot runners. It is advisable to clean with the mould open or to inject small quantities (up to 50%) into the closed mold.

  11. How much EKO SAVE is required ? 1½ times volume of the cylinder capacity to clean the cylinder and screw. If the machine has not been purged for a long time or is old it is probable that you will need to purge with twice to three times the cylinder capacity. • In the case of blow molding heads and blow film dies we recommend enough material to fill cylinder, die and head 1.5 times volume. • See Quantities table below.

  12. Quantities needed INJECTION EXTRUSION

  13. Can you shut down Machines on EKO SAVE? • We recommend shutting down your machinery with EKO SAVE purging compound, this process will eliminate and remove all loosened and degraded colorants, additives, and plastics that may be stuck in your machine.

  14. How do you overcome difficult pigments & burnt degraded resin? • Ensure that you work with the purging instructions fully. • Raising the working temperatures in difficult areas such as blow molding heads, adaptors, flat die extruders & hot runners. • Leaving the Eko purge in the machine for recommended length of time. • Repeat the cleaning process twice in succession.

  15. Can you reuse the EKO- SAVE purge materials? • You can use the purge as a regrind filler at maximum use of 5-7% weight. • This should only be used with darker colors & with products of low mechanical demands.

  16. Good Luck
