I believe everyone will encounter the problem of overheating and color change in the flow channel. After producing one color, when producing another color, it is necessary to replace the remaining color to ensure normal production. The simple method is to directly shape and replace the hot runner, but this method will waste a large amount of raw materials, which can be achieved by airing the runner until the hot runner is replaced completely. Regardless of which method is better during use, it will consume a lot of time and waste raw materials. Due to the complex structure of the hot runner and the large number of dead corners in the mold, it is not easy to gradually replace and clean the mold solely by the flow of materials. Even if the overall color conversion is completed, there will still be a small amount of residue of the previous color in the attachment of the hot runner injection point, which requires more time and material loss.

The screw cleaning materials currently available in the entire thermoplastic market can quickly and thoroughly clean the screws and hot runner of the cleaning equipment. The professional modification of materials is suitable for a wide range of temperatures, and the chemical additives released by the additives added to the material at a certain temperature can quickly decompose stubborn pigments, damage the molecular chains of the original material, and detach from the metal surface. Geodesic cleaning is achieved by soaking for a certain period of time. Solve the waste of time and materials caused by unpredictable color change in the hot runner. According to effective data, chemical screw cleaning materials can save 70% of cleaning time and 70% of material loss.
