Purging compound is a resin-based product that is widely used by most thermoplastic producers to clean screws, molds, nozzles, dies, or hot runners of injection molding machines and extruders. Its purpose is to reduce machine downtimes and scrap rates when a material or color change occurs, making it an essential product for any plastic manufacturer.
The traditional method of cleaning equipment is by using virgin resin, but this method can be time-consuming and lead to high scrap rates. That's where purging compounds come in. They contain components such as emulsifiers, abrasive agents, or foam agents that help in speeding up the removal of contamination from the barrel and are safe for the machinery. This makes purging compounds faster and more efficient than using resins. Using purging compound for injection moulding, extrusion, blow moulding has many advantages. For one, it reduces scrap by effectively clearing out the residues of the last production and colors. This further reduces the amount of waste generated and enhances the productivity and efficiency of your business.
Purging compounds also help in reducing downtime, which is extremely precious in a production facility. By reducing the time wasted in resin changeovers, you can increase the efficiency of your operations and produce more products in less time. One of the biggest benefits of using purging compounds is the elimination of contaminants. The chemical components of purging compounds for plastic help in eliminating carbon residues, color streaks, and gels during production changeovers. This not only improves your factory rejection rates but also avoids frustrating machine stops during production.
Another advantage of using purging compounds is that it prevents screw pulls. Contamination that is not removed can hamper the functioning of your machine, and you may need to pull out the screw to do a manual cleaning at some point in time. With the help of purging compounds, you can prevent this from happening and keep your machine running smoothly. Many injection molding changeovers might take longer when there are stubborn color residues inside the hot runners. However, there are now purging compounds on the market that can be used safely through the mold. For this scenario, Novanative Ultra Purge purging compounds grades are especially useful and highly recommended.
Finally, using purging compounds is cost-effective. It helps in decreasing cost by reducing downtime and scrap during color and material changes. During the evaluation of this solution, you need to remember that purging compounds produced by different companies are not equivalent. The quantity required and outcomes attained with one cleansing compound might not be the same for other purging compounds. In conclusion, purging compounds are an essential product for any plastic manufacturer. They help in reducing scrap, lessening downtime, eliminating contaminants, preventing screw pulls, removing contamination from the hot runners, reducing rejection rates, and are cost-effective.
