New medical device molding machine uses ultrasonic melting technology
Release date: 2014-05-21
The spray molding method is widely used to process plastic medical products. However, there is a new type of molding machine that not only saves energy but also greatly saves material costs. Ultrasion's Sonorous 1G molding machine uses ultrasonic technology to melt plastic materials. This molding machine was exhibited this week at Medtec UK (Mechanical Technology and Equipment Trade Show), which is not only used in the medical industry, but also in many other industries.
Miraculously, Ultrasound itself cannot transfer heat. The process of plastic melting is caused by ultrasonic vibration and liquefaction. This new method is more concentrated and efficient than other methods of melting plastic by full heating. According to Ultrasion, the ultrasonic melting method can effectively save about 90%.
At the same time, the ultrasonic melting method is more targeted, which means that waste on materials can be reduced. The traditional jet molding process results in excess molten material having to be discharged from the machine, resulting in waste. However, Ultrasonic can accurately calculate the amount of material required for each styling process. Therefore, it can save 60% to 80% of materials.
In addition to energy saving and material saving, the study found that the use of ultrasonic melting technology can significantly reduce the viscosity of plastics. The thinner the liquid, the longer, flatter and finer the product can be made. The lower the viscosity, the lower the pressure during the molding process, which helps to avoid damage to the components during the overmolding.
