In a non-climate controlled environment, cold molds will often ‘sweat’ on humid days due to the mold surface temperature being lower than the dewpoint of the surrounding air.
Question: We have to warm up our molds during the summer to keep the molds from sweating. This results in much longer cooling times. Management will not add climate control to the facility, but can the molds run faster?
My Response: If you cannot control the plant environment, you can still control the mold environment. Many molders will put dehumidifiers next to the machine to provide a dry air environment within the clamp area.
More Comments: If the sweat is mild, you can also gently blow compressed air at the core and cavity surface since this air typically has a dewpoint of -10 to -20 degrees.
