In the production of plastic products, the efficiency and quality of the process depend not only on the equipment itself but also on proper preparation during startup. One of the most important steps is cleaning the machine before a new production cycle. Using a specialized purging compound instead of standard methods provides a number of significant advantages.
Significantly shorter preparation time
❌ When changing color or material, traditional cleaning with virgin resin is slow and often leaves residues.
✅ With a purging compound, the process is much faster (from hours to minutes) and more effective – completely removing residual materials.
Less Waste and Lower Costs
❌ Inefficient cleaning results in a large amount of discarded material, which in some cases cannot be reused, or requires additional resources and time for reprocessing.
✅ With a purging compound, there is less scrap in the first production runs, lower raw material consumption, and more cost-efficient production in the long term.
Higher Product Quality
❌ Residues from previous colors or contaminants can cause defects such as black specks, streaks, or color variations.
✅ Thanks to purging compounds, transparent and colored parts achieve higher quality, visual defects are avoided, and the machine operates more reliably.
Longer Equipment Lifespan
❌ Some cleaning methods are abrasive and can damage the cylinders and screws of the machine.
✅ Ultra System’s specialized purging compounds are non-abrasive and gentle on metal parts, reducing maintenance needs and extending machine life.
