What impacts does high-pressure cooled-water effect on the injection molding process of preform mold?
1. Improve cooling efficiency
During the preform injection molding process, the use of high-pressure chilled water can significantly improve cooling efficiency.Due the temperature of the chilled water lower and faster flow rate, it can more quickly absorb the heat released by the mold and product molding during the preform injection molding process, thereby lowering the mold temperature and accelerating the cooling and solidification molding of the product. The rapid cooling helps reduce injection molding cycle times and improves production efficiency.
2. Improve products quality
The use of high-pressure chilled water has a positive impact on the product quality of preform injection molding. Chilled water can cool the mold more quickly and evenly, avoiding product surface defects caused by uneven temperature, such as cracks, bubbles, etc. At the same time, rapid cooling can also reduce the thermal degradation of plastics and maintain their good mechanical properties and appearance quality. For products such as bottle preforms that have high requirements on size and appearance, the use of high-pressure frozen water can significantly improve the product quality.
3. Extend mold life
The mold is the key in the injection molding process, and its temperature control has an important impact on the life of the mold. The use of high-pressure chilled water can quickly and effectively reduce the working temperature of the mold, reduce thermal fatigue and wear, and thus extend the service life of the mold. In addition, chilled water can also reduce the adhesion of plastic on the surface of the mold cavity, and reduce the difficulty and workload of cleaning the mold.
4. Reduce production costs
Although the use of high-pressure chilled water may increase some initial investment, it can help reduce production costs in the long run because it can improve production efficiency, improve product quality and extend mold life. At the same time, the use of chilled water can also reduce energy consumption, further reducing production costs.
