Plastics production and processing

Plastic floorboards are made of coloured granules and shaped by deep-drawing. After the production process, it must be guaranteed that the colour of the floorboards is homogenous and that there are no colour differences. …

The thickness of blown films is an important aspect in terms of constant quality in blown film production. During production, strong thickness tolerances can occur. The blown film system from Micro-Epsilon measures the profile of the film with or…

As well as the visual requirements, instrumentation panels also have to fulfill functional and security requirements. Often the passenger airbag has a predetermined breaking line which is generated using a laser. This "weak point" ensures the…

Foreign bodies, uneven distribution of the adhesive or unevenness when closing may produce open joints between the top material and the sidebars. The scanCONTROL laser profile sensors check if there are open joints and detect their gap size. …

The thicknessCONTROL measurement system is used for thickness measurement of plates and strip materials. Depending on the measurement task and materials, the head is equipped with different sensors that measure in a fixed track or in a traversing…

In its sensor housing, the combiSENSOR combines an eddy current displacement sensor and a capacitive displacement sensor. This unique sensor concept enables one-sided thickness measurement of electrically non-conductive materials on metallic…

In order to avoid defective production and to conserve resources during the extrusion of plastic products, it is crucial to recognize colour deviations not just at the end of the process chain but already during the ongoing process. The accurate…

Immediately after the extrusion of plastic profiles, the colour is monitored directly with the colorSENSOR CFO200. Depending on the production order, the reference colors are taught into the sensor in advance and customer-specific tolerances are…

Plastic bottles are frequently manufactured in different shapes and sizes. In this respect, colour homogeneity within the product range is of particular importance with brand products. Frequently, colorSENSOR CFO200 sensors are used for inline…

In film production inline thickness measurement guarantees constant product quality. Micro-Epsilon's KS5 combination sensor measures the thickness of films in a non-contact and thus wear free process. …

In plastic injection moulding, the exact colour shade of the products is important, as the colour changes during cooling. To date, it has only been possible to measure random samples of cooled pieces. However, the colorCONTROL ACS inline colour…

As well as colour fluctuations, streaks can occur during production. With translucent films, the film colour is measured very accurately and quickly using the ACS7000 colour measuring system together with the ACS3 transmission sensor. …

colorSENSOR CFO200 sensors combined with the CFS3-A20 transmission sensor from Micro-Epsilon are used for this quality inspection. The measurement on the sheets takes place directly after cooling in the production line. The distance between the…

Thickness measurement using displacement sensors is a wide application area. Basically there are distinctions between non-destructive/destructive, non-contact/with contact and one-side/two-sided thickness measurement. The Micro-Epsilon measuring…

Surfaces play an important role in the functionality and aesthetics of plastic components. Therefore, optical surface inspection is a central approach for 100% quality control. Deflectometer-based inspection systems from Micro-Epsilon inspect…

In industry, the need for adhesive film is increasing. When producing the film, depressions and folds often occur, rendering the film unusable. Therefore, the customers’ requirements for an impeccable surface are increasing. For this purpose, a…

It is essential that the “width” and “height” of the cable tie strap, as  well as the “tooth pitch” are monitored concurrently and constantly during the production of the continuous loop straps. These values are crucial to ensure a consistently…

The production of polycarbonate sheets involves inline monitoring of colour shades. The measuring principle applied with these transparent sheets is based on the transmitted light principle using colorSENSOR CFO200 sensors. The sensors detect…

An important criterion for the quality or the wear of tubes in industrial applications is the dimensional conformance of the internal diameter over the complete length. Where high demands are made on accuracy, a quick and reliable recording of…

High precision pipe measurement Pipes, fittings and sleeves are inspected using random sampling for their dimensional accuracy in a special system. Sensors of the optoNCDT 1700 series rotate mounted on a plate. The laser beam is deflected by 90°…

In the extrusion of high quality plastic profiles, adherence to tight manufacturing tolerances is crucial. For quality assurance, laser profile scanners from Micro-Epsilon are used. Thanks to the surface compensation, the scanners reliably detect…

Users of injection molding machines for plastics processing are facing increased quality requirements imposed by end-users, in particular for automotive applications. Because of this trend, the importance of inline temperature control right after…

Sprayed skins for vehicle dashboards and for airbag cladding are sprayed into a heated mold using a robot-guided nozzle. For safety reasons, extremely low tolerances are required for airbags. For this reason, the thickness of the sprayed skin…

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…

moldCONTROL is a thermography solution for recognizing quality fluctuations in injection molding production. The compact, industrial thermal imaging camera captures a thermal image of the component directly after the injection molding process.…

Depending on the respective measurement task, it is sensible to carry out a two-sided thickness measurement. Arranged opposite the material, two displacement sensors detect the thickness. This measurement arrangement is particularly suitable for…
