Cleaning compound for injection moulding |
|---|
|
As a result of just-in-time production requirements injection moulding are facing shorter runs and a rapid growth in the number of color- and/or material changes. A fast and cost-effective cleaning compound is required. ECONOCLEAN thoroughly cleans injection moulding machines. Burnt polymer residue as well as black specks, caused by carbonized material, are swifily removed from cylinder, screw and hotter runner gates. ECONOCLEAN also removes pigments that have a strong tendency to stick to screw and cylinderwall. The ECONOCLEAN cleaning process even cleans negative flow areas and "dead corners" quickly, safety and easily. By regular preventive maintenance with ECONOCLEAN an injection moulding machine will cleaned faster, reducing downtime and material waste. The possible cost savings are significant, as your distributor can show you in a calculation. |
| Less downtime | ECONOCLEAN works effective, and reduces the need for pulling the screw. |
| Shorter start-up time | ECONOCLEAN removes black specks effectively, making the start-up phase for the next run shorter, causing |
| Reduced loss of material | through shorter start-up periods, and |
| Less cleaning compound | ECONOCLEAN needs only 1½ to 2 times the cylinder contents for an effective cleaning. |
| Concentrated | ECONOCLEAN is available in ready-for-use formulations, but also as a concentrate. |
| Less scrap |

 | ECONOCLEAN | is a resin that is as easily processable as plastics. |
| ECONOCLEAN | is composed of materials that have the GRAS classification (FDA norm for Generally Recognized As Safe). |
|---|---|---|
| ECONOCLEAN | is odourless, also when processed. No special precautions are required. |
| The residue is a plastic with inert minerals, which can be processed as such. | ||
| ECONOCLEAN | is available in 25 kg quantities, in recyclable carton boxes with a plastic liner. |
Process | TOP |
| Econoclean will foam slightly in the extruder, so it reaches into the dead corners of the extruder and die. Burnt residues are released from screw and cylinder wall through a chemical reaction, and extruded by the purging properties of Econoclean. Econoclean also has a polishing (NOT abrasive) effect, which leaves the surfaces inside the extruder clean and smooth. |
 Regular preventive maintenance controls the building up of burnt residues, and makes every cleaning more effective. |
