Fasti GmbH of Kufstein, Austria, has developed a new chiller technology for blow molders that uses a chilled mixture of water and air, also called “saturated steam.”
Fasti said the equipment, named DryWater, can boost production by 10-30 percent. The saturated steam is injected into the part to be blown, then the water particles dissolved in the air react with heat radiating from the product. This continues until it reaches a saturation level of 100 percent. This steam, now heavily loaded with water molecules, is then available for the blowing process.
According to Fasti, the mixture is extremely capable of removing heat from a blow molded part. Also, the steam creates a very smooth inner surface, Fasti said. The saturated steam, or mist, does not remain on the part.
Fasti equipped a mold for a six-layer automotive gas tank with the DryWater system, and cut the cycle time by 16 seconds, to just 79 seconds. That equaled a 20.6 percent production increase.
The company's U.S. operation, Fasti USA Inc., is in Elgin, Ill.
