Vittmann Company Injection Molding Mold Condensation Prevention Device MAP
Vittman Corporation MAP
Dry air is supplied to the sealed injection molding line to prevent condensation on the mold.
The revolutionary device "MAP," which prevents the major enemy of injection molding, "condensation on molds," surrounds only the area where the cooling water of the injection molding machine circulates with plastic sheets or similar materials and blows dry air only into that space. This is an energy-saving type of condensation prevention system. Since it eliminates the need to adjust the cooling water temperature according to the outside temperature, molding becomes stable throughout the year, and defects in molding are reduced. If humidity control for the entire factory was previously necessary, costs related to air conditioning can also be significantly reduced.

Applications/Examples of results
The molding cycle of injection molding can be shortened by lowering the temperature of the cooling water flowing through the mold. However, lowering the cooling water temperature has disadvantages, such as causing condensation on the mold, which negatively affects the appearance of the product. As a result, many companies use air conditioning to control mold condensation throughout the entire factory where injection molding machines are located. However, this method requires large air conditioning units to cool the entire factory, leading to high initial investment and operational electricity costs, and it also makes the operators inside the factory feel cold. Moreover, the reality is that "the cooling water temperature of the mold cannot be lowered that much."
Detailed information
-
The temperature at which the moisture in the air becomes saturated and condenses is called the dew point temperature (or absolute humidity). Condensation on molds is caused by moisture in the air, but in environments like Japan, where there are significant temperature and humidity differences throughout the year, controlling the dew point temperature has been a very challenging task. The MAP system blows and retains dry air only around the molds of the injection molding machine, preventing condensation on the molds caused by low-temperature chiller water, thus allowing for a consistent humidity level throughout the year.
