Plastics production and processing

Thermography for injection molding processes

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. The software compares the infrared images associated with the component (actual) to stored references (target). The identified temperature differences provide the basis for a good/bad decision reported back to the handling system.

Two-sided thickness measurement

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 high speed measurements and fluttering materials. Micro-Epsilon also offers sensors and turnkey systems for two-sided thickness measurements.

One-sided thickness measurement of films

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 objects. Its field of application is the thickness measurement of plastic film or of plastic coating on metal plates. Connected to the sensor via a cable, the controller processes and calculates the signals in order to put them out via interfaces.

Defect recognition on worktops

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.

Thickness profile measurement of strips and plates

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 method. Comprehensive software packages and interfaces enable measured values to be recorded.

Temperature monitoring of thin plastic films

With blown film extrusion, non-contact temperature measurement is a difficult measurement task. Ambient radiation also penetrates thin films and distorts the intrinsic radiation of the films. The infrared CT-P3 and CT-P7 pyrometers only detect the infrared radiation emitted by the plastic films and ignore the penetrated ambient radiation. This is how high precision detection of the surface temperature is possible.

Gap measurement of extruded plastic profiles

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 the profiles of black rubber surfaces. For gap measurement, special software packages are available with which different parameters can be easily selected.

Surface defect detection of plastic attachments

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 shiny surfaces and detect even the smallest of deviations. The defects found are evaluated and displayed in the 3D model.

Inline color measurement of transparent films

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

Color measurement of extruded parts

In order to avoid defective production and to conserve resources during the extrusion of plastic products, it is crucial to recognize color deviations not just at the end of the process chain but already during the ongoing process. The accurate colorSENSOR CFO color sensors are used for color recognition in the process and transmit color deviations directly to the control system.

Le système de mesure de couleur en ligne des pièces moulées en plastique

Lors du moulage par injection plastique, le coloris exact des produits est souvent un facteur déterminant, car leurs couleurs changent pendant le refroidissement. Jusqu’à présent, seuls des prélèvements sur les pièces refroidies étaient mesurés. Le système de mesure de couleur en ligne colorCONTROL ACS de Micro-Epsilon peut désormais exécuter un contrôle à 100 % à l’issue du démoulage.

TIM 160 pour applications de moulage par injection

Les utilisateurs de machines de moulage par injection de matériaux plastiques se voient confrontés, à des exigences de qualité croissantes de la part de leurs clients finaux, dans le domaine de l‘automobile tout particulièrement. De par cette évolution du marché, un contrôle en ligne de la température effectué immédiatement en aval de l‘extrusion devient un aspect de plus en important en tant que caractéristique de qualité globale.

Mesure sans contact de l'épaisseur de films en ligne

Dans la production de films, une surveillance du processus en ligne garantit une qualité de produit constante. Le capteur KS5 à techniques combinées de MICRO-EPSILON mesure sans contact, et donc sans usure, l'épaisseur de revêtements de films.

Epaisseur des films soufflés

La qualité des films soufflés dépend particulièrement de leur épaisseur constante. Cependant, lors de la production, leur épaisseur peut en partie fortement varier. Le système de mesure d’épaisseur pour films soufflés de Micro-Epsilon mesure, sans et avec contact, le profil des films dès leur sortie de la filière d'extrusion. Posé sur un cadre inverseur, le système contourne la gaine tubulaire en continu et fournit les données recueillies au système hôte pour la commande de la filière d'extrusion.
