Sensors & Applications Plastics Industry

Sensors and measuring systems for plastics production Miniaturization and increased production speeds together with rising economic efficiency are the determining factors in the production and processing of plastics. Quality, function and touchscreen communications of the final product require reliable measurement and inspection procedures in every manufacturing stage. Compact and high speed sensors ensure highest reliability in almost any area where high precision is expected - from machine monitoring to fully automatic quality control of the final product. scanCONTROL High-end laser scanner...

Thickness & geometry measurements Precise thickness measurement of coated plastic film The compact thicknessGAUGE sensor system is used for coating thickness measurement of separator film. It is equipped with a white light interferometer and detects both the film thickness and the coating thickness with submicrometer accuracy. Measuring system: thicknessGAUGE

Thickness measurement of film, plates and sheets thicknessGAUGE sensor systems are used for precise thickness measurements of strip materials, plates and sheets up to 25 mm. These systems can be equipped with different sensor types, measuring ranges and measuring widths, which enables inline thickness measurement of different materials and surfaces. Measuring system: thicknessGAUGE Thickness profile measurement of strips and plates The thicknessCONTROL measuring system is used for thickness measurement of plates and strip materials. Depending on the measurement task and materials, the head is...

Inline color monitoring of plastic bottles Plastic bottles are frequently manufactured in different shapes and sizes. In this respect, color homogeneity is indispensable particularly with brand products. Due to different bottle shapes, distancedependent color deviations occur which must be compensated for by the color sensor. Therefore, colorSENSOR CFO200 sensors are used as they offer a multi-teach function combined with a high measuring rate and color accuracy. With more than 320 colors in 256 color groups, different production batches and variants can be detected reliably. Inspection of polycarbonate...

Photo: University Duisburg-Essen, Institute for Product Engineering, Chair for Construction and Plastics Machinery Inline color measurement of transparent films As well as color fluctuations, streaks can occur during production. With translucent films it is possible to measure the color based on the transmitted light principle. The colorCONTROL ACS7000 measures the film color inline at high speed and at maximum precision. Sensor: ACS3 transmission sensor, colorCONTROL ACS7000 Inline color measurement of injection-molded plastic parts In plastics injection molding, color measurement can be performed...

Non-contact process monitoring

High-precision film thickness measurement The interferometer is used for high-precision thickness measurements of transparent flat film. A decisive advantage is the distanceindependent measurement, where a stable nanometer-accurate thickness value is achieved. This is how the target can move within the measuring range without influencing the accuracy.

Fuel filler flap inspection One component that many automotive manufacturers and suppliers produce in plastic is the fuel filler cap. As fuel filler flaps are positioned in a prominent location, the surface must meet the high quality requirements. During production, small sink marks can appear on the visible side of the flap. These are only a few micrometers deep but visible to the human eye depending on the painting. The surfaceCONTROL is used for surface inspection of fuel filler flaps. Both in production monitoring and when inspecting incoming goods, the system reliably detects and evaluates...
