This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.

A multi-functional utility skid for use with an air compressor, a chiller, and a connection having a first end engaging the chiller and a second end to provide utilities to a blow-molding machine for blow-molding articles. The skid is located proximate the machine and includes a pump engaging the second end of the connection, receiving chilled water from the chiller, being located proximate the chiller to minimize the length of the connection, and providing chilled water to both the machine and a separate supply of chilled water. The skid further includes an integral unit combining a dehumidifier that controls the humidity of the environment surrounding the machine with a heating, ventilation, and air conditioning unit that receives the supply of chilled water from the pump, controls the temperature of the environment surrounding the machine, and supplies conditioned air to the dehumidifier thereby avoiding the need for a heat exchanger.
