Extrusion International 1-2019

PREVIEW 32 Extrusion International 1/2019 Hall A5, Stand 1010 The Filmtest is an offline measuring system for ex- truded films, used for process optimization and qual- ity control labs. The combination of several measur- ing functions in an offline system makes the Filmtest a valuable tool for a professional quality control. Due to fast and easy handling it is practical to perform measurements at every roll change. Consistent mea- surement means you can provide your customer with more assurance that delivered production is within specification. The operation of the system is easy enough that any operator can do it. The Filmtest helps to reduce the work in the laboratory. For example, in addition to the thickness measurement, the unit weight of the sam- ple is also calculated eliminating the manual step of weighing the film. The Working Principle • A sample of the film is cut by means of a cutting plate, that guarantees that the exact width of the sample is 150mm. • The „Variospeed“ sample scanner uses optical sen- sors to track the film edges; automatically transporting the sample through the capacitive measuring device. • The length and the weight of the sample is measured. • The square meter weight is determined using length, width and weight, then the average thickness is calcu- lated based on the density. • The thickness profile is measured by a high-resolu- tion capacitive sensor. Advantages • The sample of the film does not need to be formed into a loop, it will be transported through the capaci- tive measuring device. • Film samples that are cut into several pieces can be measured one after the other, the software will put the measuring data together and will create the com- plete profile. • The square meter weight is determined using length, width and weight. Then the average thickness is calcu- lated based on the density. This method allows a much more precise thickness profile measurement than oth- er systems on the market. • All measuring values will be registered during the same measuring operation.
