We handle 'Cell Purge', which is suitable for cleaning injection molding machines and extruders. The 'Cell Purge' with GF (glass fiber) removes carbonized foreign matter. Melted resin will carbonize if it comes into contact with air or is left heated for a long time. Since the GF grade contains less resin component due to the presence of GF, if carbonized foreign matter cannot be sufficiently removed on its own, we recommend using it in combination with the non-filler grade "NX-VN". 【Features】 ■ Effectively removes carbonized foreign matter as it flows while scrubbing the surface of the carbonized resin. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

We handle 'Cell Purge', which is suitable for cleaning injection molding machines and extruders. We will introduce a maintenance method that does not produce carbonized foreign matter using this product. It is best to prevent carbonized foreign matter from occurring rather than removing it after it has appeared. Resin that has completely carbonized will not soften even when heat is applied. It strongly adheres to the surface of metals, but it can sometimes come off unexpectedly, and if it mixes into the molded product, it becomes "carbonized foreign matter," leading to molding defects. 【Three Rules to Prevent Carbonized Foreign Matter】 ■ Do not leave the molding machine empty ■ Regularly use Cell Purge to discharge resin that is about to carbonize ■ Perform cleaning operations using Cell Purge at least once a day *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

At Ube Industries, Ltd., we conducted a cleaning evaluation of "Cell Purge NX-P2" for color change in foam PP molding using hot runner molds. We continuously molded "Cell Purge NX-P2" directly from the previous material and then continued molding the subsequent material. The previous material was sufficiently discharged after 15 shots, and the replacement to the next material was completed in just 4 shots. No touch-up processing was needed at all during the molding of the next material. The cleaning of hot runners, which has traditionally been very difficult, can be carried out very easily using Cell Purge NX, specifically the hot runner type. We encourage you to consider the Cell Purge NX series for improving the efficiency of color change processes during molding.

To achieve low residue, the compatibility of the resin is important. Especially in hot runners, please select a grade suitable for the resin you are using to prevent the residue of purge agents in dead spaces. "Cell Purge," in addition to its good compatibility, significantly contributes to self-extraction through surfactants. Surfactants increase the contact angle θ when discharging the front material, making it easier to discharge, and then play a role in facilitating the discharge of the Cell Purge itself when replacing it with the back material. In other words, surfactants exist at the interface between the Cell Purge and the metal surfaces of the cylinder/screw, allowing the Cell Purge to slide along the cylinder/screw surface. When using ordinary resins, the resin near the metal wall is not easily discharged. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

In general, it is said that using a resin with higher viscosity than the previous material is effective for efficient purging, but this applies to the resin near the center of the flow. To efficiently discharge the resin from the inner walls of the cylinder and screw, it is necessary to utilize not only viscosity but also interfacial tension. Although the cylinders and screws of molding machines are not treated with Teflon, "Cell Purge NX" utilizes the power of surfactants to control the interfacial tension existing between the previous material, the subsequent material, and the metal surfaces of the cylinder/screw, allowing for smooth discharge of the previous material. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

In transparent resins such as PC, PMMA, and transparent ABS, residuals can be quite noticeable, and even a very small amount of "purging" residue that would not be an issue with colored materials may appear as white streaks. Such residues are not easily removed even if molding continues. If residuals become a problem with transparent resins, please stop molding temporarily, minimize the amount measured as much as possible, and use the air shot method to purge by repeatedly measuring and injecting while keeping the nozzle away from the mold. In the case of hot runners, similarly, open the mold and repeat the measuring and injecting process, discharging with an air shot. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

"Cell Purge" can be effectively used in the extruders for compounds that produce pellets. If you add it before removing the screw, you can remove the screw with less force. However, there is no cleaning effect when it is not in a molten state, so cleaning below the hopper cannot be performed. 【Cleaning Method for Extruders with Compounds】 ■ After completing the pelletizing process, discharge all materials from the extruder. ■ For a twin-screw extruder, add a certain amount of Cell Purge to the feeder; for a single-screw extruder, add it to the hopper, and rotate the screw to flow the Cell Purge. ■ When the discharged resin is white and there is no residue from the previous material, stop the screw rotation, open the die, and remove the resin remaining in the die. ■ Flow the next material while the die is open, and once it has been replaced, the cleaning is complete. ■ Close the die, check the condition of the discharged resin, and then start pelletizing. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

Extrusion molding is all about viscosity and the shape of the die. The "Cell Purge" hot runner grade has sufficient discharge capability for relatively small dead spaces and is compatible with most molding methods when using small machines. Additionally, there are effective grades for certain resins and molding methods. The required amount of "Cell Purge" varies significantly depending on the shape and capacity of the die. 【Molding methods that can expect sufficient effectiveness】 ■ Tube molding ■ Irregular extrusion molding ■ Inflation film molding (Polyethylene: NX-E) *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

As a method for purging using "cell purge," we recommend reducing the measurement values and repeatedly measuring and injecting. This is to change the direction of the resin flow as much as possible to ensure that no resin is left behind in the dead space. While increasing back pressure to flow the resin, known as "back pressure purge," is also effective, if "cell purge" leaks due to insufficient pressure, it will not be effective. Therefore, when purging during the measurement and injection operation, please apply back pressure at a level that is about 2-10% weaker to minimize leakage from the nozzle. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

Here is the cleaning method for "Selpurge NX for hot runners." Please be sure to use a grade suitable for the resin being used. There are two methods, but the amount of Selpurge used is almost the same in either case. 【Method 1】 ■ Perform an air shot of Selpurge with the mold open - After completing the molding of the preceding resin, set the molding conditions and repeat weighing and injection. - In a valve gate hot runner, open and close the gate during weighing and injection. - It is more effective to reduce the weighing amount and increase the frequency of gate opening and closing. *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.

The basic usage of the plastic molding machine cleaning agent "Selpurge" involves repeated lightweight injection operations. When cleaning the cylinder/screw of the injection molding machine, please set the molding conditions and repeat the weighing and injection after finishing the molding of the preceding resin. After purging, change to the molding conditions for the next material, and once the temperature stabilizes, discharge the Selpurge with the next material. It is effective to apply back pressure lightly, just enough to prevent the Selpurge from dripping from the nozzle. 【Molding Conditions】 ■ Weighing: 10 - 30mm ■ Cylinder Temperature: Same as during previous material molding ■ Screw Rotation Speed: 50 - 70% ■ Back Pressure: 2 - 10% ■ Injection Pressure: 70 - 99% ■ Injection Speed: 70 - 99% *If you would like a sample, please contact us or download the sample request form and feel free to apply via fax.
