Yes, DOME® Purging Compound is the ultimate solution for cleaning screws, nozzles, molds, hot runners, and dies of injection molding machines and extruders.

Selecting a purging compound specifically formulated as a low-residue material is crucial for various purging applications.

For materials that are particularly sensitive to residue, such as clear PC, DOME® provides specialized purging compounds like our DM-PC088B, which are highly effective.

Additionally, adhering to correct purging procedures, especially purge displacement techniques, will minimize the residual presence of the purging compound.

Yes, DOME® Purging Compounds are safe for your machine as they do not contain corrosive chemicals, are abrasive-free, and do not harm equipment. There is a misconception that mechanical purging compounds are abrasive, but this is not true. In fact, purging compounds help reduce machine wear and tear and prolong the life of your screw and barrel.

Yes, the DOME® purging compound DM-PC100HC  has special procedures that make difficult temperature changeovers very easy.  It is suitable for high and low-temperature conversion cleaning of resin materials such as LCP/PEEK/PEI/PSU/PTFE, with processing temperatures ranging from 250°C to 400°C. It is suitable for Twin screw modified/single screw granulation extruders.

DOME provides a range of purging compounds designed to address black specks and carbon contamination effectively. Compounds like DM-PC001U, DM-PC003U, and DM-PC058B deliver exceptional cleaning outcomes.

To deter carbon buildup and uphold machine cleanliness, we suggest incorporating one of our general-purpose grades into your preventive maintenance routine.

For tailored guidance on selecting the ideal cleaning solution for your project, we recommend consulting DOME’s purging compound experts.

Yes, DOME® has a special cleaning agent for machine shutdown seal maintenance to help make start-up faster, more efficient, and less problematic. The recommended model is DM-PC058M, it is also more cost-effective in terms of price.

Methods such as flushing the machine with the next resin or using regrind are time-consuming, material-wasting, and ineffective in removing color and carbon contamination.

Commercial Cleaning agents, especially high-quality ones like DOME® Purging Compounds, are designed to address these critical aspects and contribute significantly to the overall profitability and sustainability of manufacturing operations.

1. Process Efficiency: They help reduce downtime during material changeovers and start-ups, keeping production lines running smoothly and efficiently.
2. Cost Savings: By minimizing scrap and waste, cleaning agents save significant amounts of production material, reducing overall costs.
3. Product Quality: They effectively remove contaminants and residues, ensuring the final product meets quality standards and reducing the risk of defects.
4. Maintenance Reduction: Regular use of cleaning agents can reduce the frequency and extent of maintenance required on equipment, leading to longer equipment lifespans and further cost savings.
5. Energy and Labor Costs: Cleaning agents can lower energy usage by maintaining optimal operating conditions and reducing the labor required for manual cleaning processes.

You will save considerable time and money when you implement a DOME® Purge Program.

The time required for purging your machine can vary significantly depending on several crucial factors such as the size of the machine, the condition of the screw and barrel, the type of resins being purged, and more. Purging times can range widely based on these conditions. For instance, purging a 30-ton machine typically takes around 10 minutes, whereas purging a 3000-ton machine may require 40 minutes.

Moreover, the level of contamination or the complexity of the material or color change will also impact the efficiency of the purging process. It is recommended to consult with a DOME® Purging Expert for a more accurate estimation based on your specific requirements.

Absolutely. DOME® Purging Compounds significantly simplify screw pulls, making them safer and more cost-effective. You can directly utilize our purging compounds for equipment cleaning without the necessity of screw pulls. This results in a reduction in the frequency of screw pulls. This innovative product greatly aids in preventive maintenance and minimizes unplanned downtime.

Yes,  DOME® Purging Compounds can hold a bubble in blown film extrusion. DM-PC058B is usually the best choice for this application. It saves customers countless hours of downtime.

No, there is no one-size-fits-all purging compound available.

DOME® offers a comprehensive range of purging compounds on the market, but different products are better suited for specific applications. For instance, DOME® purging compounds DM-PC001U and DM-PC0013U are examples of general-purpose purging compounds. They are ideal for preventive purging, material, and color changes, cleaning black specks and carbon contamination, and are compatible with a variety of resins and processes. General-purpose purging compounds are effective with popular commodity and engineering resins within specific processing temperature ranges.

1. DOME® purging compound is a scientifically engineered purging compound that can be effectively used to clean a wide range of resins.
2. It takes only a small amount of purging compounds to get the job done right.
3. All DOME® purging compound grades are safe and effective for cleaning hot runner systems, mixing nozzles, check valves, melt pumps, and extrusion dies.
4. DOME® purging compound is competitively priced and has the highest performance-to-cost ratio of any commercial purging compound on the market today.
5. The active ingredients in the DOME® purging compounds neutralize hydrochloric acid (HCl) formed by PVC, thus preventing material contamination, black specks, and steel corrosion.
6. DOME® purging compounds do not contain corrosive chemicals, do not harm equipment, complies with RoHS standards.
7. DOME® purging compounds can clean hot runners and precision molds, with no wear, and no blockage of runners, and molds can be cleaned in molding.
