　　In the plastics industry, the chiller mainly acts on the molding mold of plastic processing machinery. It injects frozen water into the runner inside the mold, cools the mold at a constant temperature through heat exchange, and maintains the temperature at a constant state to meet the needs of the production process. In this process, the mold is equivalent to a heat exchanger. Let's look at the cold water injection molding machine solution provided for a plastic factory in detail below:

　　12 injection molding machines in this plastic factory:

　　Respectively: 1000KN: 3 sets, 1800KN: 2 sets, 2500KN: 3 sets, 3800KN: 4 sets, the required water temperature is 10 degrees

　　Technology After reading the customer’s site, we recommend that the customer use a 30P water-cooled screw unit for centralized cold water supply. The centralized water supply workshop looks orderly and can help customers save costs. (The 30P water-cooled screw unit is equipped with a 40T cooling water tower, a 1 ton heat preservation water tank, and a 5.5P circulating water pump).

　　After using the chiller, the surface finish of plastic products is greatly improved, and the surface traces and internal stress of plastic products are reduced, so that the products are easy to demold without deformation and shrinkage, thereby improving production efficiency and greatly reducing defective products.
