48 smart_molding international 4/2022 sensors M aximum efficiency and minimal scrap – that is in - jection molders’ ultimate goal. Measuring cavity pressure is an effective way to optimize produc- tion processes. To benefit from this technology, manufac- turers must both install the sensors and interpret the data correctly – a challenge in itself, as many different factors can affect the part quality. Christian Streili, Field Service Development Manager at Kistler, explains why injection molding processes profit from expert knowledge and how Kistler helps its customers to make the most of cavity pres - sure measurement. In theory, injection molding is simple: A mold is filled with liquefied plastic that hardens in the desired shape. In reality, however, producing perfect pieces with as little scrap as possible is incredibly complicated. Different shapes and materials come with different demands, while varying external factors also affect the process. This is where tiny piezoelectric sensors come in: They help injection molders find and maintain the optimal process for each mold – no matter the materials. They measure and analyze the cavity pressure during the injection molding process. Based on these measurements, manufacturers can control the injection molding process, balance the hot runner system in line as well as automatically sort out bad parts. This is where it gets complicated, because using these sensors and interpreting the measurement results is by no means an easy task. To make the most of the hardware and measurement data, a lot of expert knowledge about the molding process and the measurement equipment is necessary. To ensure that its customers can put their piezoelectric measurement technology to optimal use, Kistler offers special service support.
