Plastic Chillers:
Plastics
In the plastics industry chillers are used for cooling the hot plastic that is injected, blown extruded or stamped. Chillers can also be used to cool down the equipment used in the manufacturing process.

tables of calculation and selection of chillers for the plastics industry.
Calculation and Chiller Selection of Plastic Industry
Cooling Chillers Plastic Injection
Chiller selection is obtained based on the following tables, the ideal selection is based on the closing capacity of the machine Table 1, Tables 2 and 3
They are complementary kilos based on the product or injector hp
Example: Based on Table 1
if you drive 3 injection of 150 to 200 tons, the chiller would be 15 toneladassi recommended only cools the mold, if desired mold and cooling the oil. 20 tons
