EdgeTech Cold Mirror Dew Point Meter COM.AIR from the United StatesHow to help improve the quality of blow molded products

In the production of blow molded products, compressed air is the "invisible pusher" that drives the formation of molten plastics, but its humidity control directly affects the surface quality of the products. When the humidity of compressed air exceeds the standard, condensed water will condense on the surface of the mold, causing defects such as flow marks, silver lines, and bubbles in the product, and the scrap rate will soar. The EdgeTech COM.AIR cold mirror dew point meter from the United States, with its excellent accuracy and intelligent response capability, has become a "technological weapon" for the blow molding industry to solve this problem.EdgeTech Cold Mirror Dew Point Meter COM.AIR from the United StatesHow to help improve the quality of blow molded products

The traditional humidity control scheme relies on capacitive or alumina sensors, which are susceptible to oil mist and dust pollution. After long-term operation, the measurement error can reach ± 5% RH or more. A large blow molding enterprise once caused a batch of 5000 medical containers to be scrapped due to inaccurate humidity testing, resulting in a loss of over one million yuan due to silver lines on the surface. COM.AIR adopts the direct cold mirror method technology, which balances the mirror temperature with the gas dew point through precise temperature control. Combined with an optical reflection system, it captures the moment of condensation in real time, improving the measurement accuracy to ± 0.2 ℃ (equivalent ± 0.3% RH) and eliminating the risk of misjudgment caused by sensor drift.EdgeTech Cold Mirror Dew Point Meter COM.AIR from the United StatesHow to help improve the quality of blow molded products

In the car bumper blow molding project, COM.AIR's real-time monitoring data shows that when the dew point of compressed air rises from -40 ℃ to -35 ℃, the surface pitting rate of the product increases from 0.8% to 12% within 20 minutes. The system immediately triggers a three-level response: local sound and light alarm alerts the operator; If the humidity continues to exceed the standard, the automatic linkage dryer will start the regeneration program; Cut off the gas source under strict conditions to prevent the mass production of defective products. By stabilizing the dew point below -45 ℃, the surface pitting rate of the company's products was reduced to 0.5%, saving rework.EdgeTech Cold Mirror Dew Point Meter COM.AIR from the United StatesHow to help improve the quality of blow molded products

COM.AIR's "prevention control optimization" full chain capability enables enterprises to shift from passive firefighting to proactive management. The built-in data recording module can store 3 years of historical data. A food packaging company found through analysis that setting the regeneration cycle of the dryer too long caused dew point fluctuations. After optimization, the regeneration frequency was adjusted from once every 8 hours to once every 6 hours. The surface dirt rate of the product was reduced from 8% to 0.3%, and customer complaints were reduced by 90%. From PET bottle blowing to automotive fuel tank molding, from food packaging to daily chemical container production, COM.AIR is redefining the humidity control standards for blow molding production with good precision, becoming an important equipment for enterprises to enhance product competitiveness and achieve intelligent transformation.EdgeTech Cold Mirror Dew Point Meter COM.AIR from the United StatesHow to help improve the quality of blow molded products
