In the plastic shoe industry,
water chillers are mainly used to cool key equipment and materials in the production process to ensure product quality and production efficiency. The following are its specific applications: injection molding machine cooling, extruder cooling, etc.
Injection molding machine cooling
Mold cooling: Injection molding is a key link in plastic shoe making.
plastic shoe industry chillers cool the mold by circulating cold water. On the one hand, it can quickly cool the mold, shorten the injection molding cycle, and improve production efficiency; on the other hand, it can ensure uniform mold temperature, make the molding of plastic shoe parts more stable, reduce product deformation, shrinkage and other defects, and improve product quality.
Hydraulic oil cooling: The hydraulic system of the injection molding machine generates heat when working. Excessive oil temperature will affect the performance and stability of the hydraulic system. The plastic shoe industry chiller can cool the hydraulic oil, maintain its normal working temperature, ensure the stability of the pressure of the hydraulic system, and make the injection molding machine more precise and reliable.
Extruder cooling
Material cooling: In the extrusion production of plastic shoe materials, the extruder extrude the molten plastic into profiles of specific shapes, such as the support strips of the soles and the decorative strips of the uppers. The
plastic shoe industry chiller cools and shapes the extruded material, allowing the plastic to solidify quickly, maintaining its shape and dimensional accuracy, and preventing the material from deforming or twisting during the cooling process.
Barrel cooling: The barrel of the extruder will increase in temperature due to frictional heat generation and material conduction during long-term operation. Excessive temperature will affect the plasticization quality of the plastic and the service life of the extruder. The plastic shoe industry chiller cools the barrel to keep it within the appropriate operating temperature range, ensuring that the plastic can be evenly plasticized in the barrel, improving the quality and stability of the extruded product.
Other applications
Cooling circulating water system: In plastic shoe factories, a centralized cooling circulating water system is usually established. The plastic shoe industry chiller is the core equipment of the system to provide cooling water for multiple equipment in the entire production workshop. The cold water is transported to each device that needs to be cooled through a circulating water pump, and then the refluxed hot water is cooled by the chiller and recycled again, realizing the recycling of water resources and reducing production costs.
Air cooling assistance: In some plastic shoemaking processes, such as drying of shoe materials and ambient temperature control in injection molding workshops, plastic shoe industry chillers can also be used to assist air cooling systems. For example, by cooling the refrigerant of the air-conditioning system, low-temperature air is provided to the workshop, improving the working environment. It also helps to keep plastic raw materials and products at suitable temperature conditions to prevent product quality from being affected by excessively high ambient temperature.
