Method and apparatus for supplying conditioned air to a blow-molding oven |
摘要 |
A method and apparatus which allows blow-molded plastic containers to be manufactured at high rates of production independent of ambient environmental conditions. The method and apparatus eliminate the need to make adjustments to blow-molding oven operating parameters when environmental conditions change and reduce defects such as caused by water spots. The method includes the steps of flowing ambient air over cooling coils to remove moisture, heating the air to a constant pre-determined temperature and delivering the conditioned air to the blow-molding oven. The apparatus includes a variable speed blower which forces ambient air at a predetermined volumetric flow rate over cooling coils and an electric heater to provide the blow molding oven with a constant volumetric flow rate of constant temperature and low humidity air.
