The next five injected parts pulled all build up from the cavity ( see picture 2 ). These scrap parts had an extra layer of removed additives on their surface . This method allows the usage of a cleaner without touching the cavity surface . This was a very important point for the production manager and general manager who already spent a lot of money for repairing damages or scratched tools .
Product performance has been evaluated over a longer period of time with a maintenance cleaning every shift . During production , a preventative maintenance scheme was made using just a small amount of Lusin ® MC1718 to cover both sides of the cavity .
Before cleaning
After approximately thirty seconds reaction time the machine was started again and the first two parts were discarded . With this method tooling refurbishment cycle increased from two to six weeks .
CONCLUSION Using Lusin ® MC1718 preventatively to remove build up in the mould allows injection moulders to extend the time between two cycles of tooling refurbishment . Regular use of it ensures that cavities remain in good condition . The use of Lusin ® MC1718 eliminates potential damage to the mould , clogging of vents , and build up in difficult to reach areas of the mould .
