During production, real time available data about the dimensional accuracy of products are invaluable. They do not only save material but also ensure that the production runs within its tolerances. Modern measurement methods can lead to devices, which are surprisingly easy to operate.

High-Tech Inspires Real Time Measurement 

Determining mechanical part properties is mandatory for quality assurance to assure compliance with performance specifications. A frequently required property is the tensile modulus, which according to ISO 527-1 must be determined to an accuracy of 1 % at strains of 0.05 % and 0.25 % of the original gauge length. The noncontact VideoXtens HP video extensometer from Zwick GmbH & Co. KG, Ulm, Germany, can be is intended for this application.

An Eye for the Essential

Quality assurance during polymer extrusion requires continuous and reliable measurement. In two European research projects, three robust, practical and relatively simple online measurement techniques for material characterization have been developed. This paper will discuss the current state-of-the-art in the real-time monitoring of extrusion processes.

Until now, the dimensioning of plastic gear required the measurement of the tooth selectively and manually before, during and after a transmission test. A newly developed in-situ transmission test bench makes it possible to investigate tooth deformation and wear behavior quasi-continuously during the transmission test, thus reducing effort and operator influence. Non-linear behavior can also be better detected.

Micrometer Accurate Measurement  of Tooth Wear

Terahertz technology supports contactless inline measurement in the micrometer to centimeter range. Wall thicknesses of pipes, hoses, and other extrusion products can be verified directly in the production process. Falling below the minimum thickness is identified immediately, thereby avoiding waste.

Terahertz and microwave methods offer a wide range of applications for testing of plastic packaging. Already established wall thickness measurements and defect detection are now joined by a wealth of other possible applications that promise process reliability and cost efficiency.

The testing of foamed products is becoming increasingly important in the packaging sector. THz measurement technology can be used to determine cell size as well as cell size distribution and local bulk density of foams

Thus, new solutions for savings have to be found. In extrusion, costs can be specifically compensated by using sustainable measuring technology as an example calculation made by Sikora shows.

The prices for plastics are rising. Extruders are not powerless in the face of this, Sikora calculates.

At the K 2022, Isra Vision will be presenting a new turnkey solution for inline inspection of individual battery cells.

At the K 2022, Isra Vision will be presenting a new turnkey solution for inline inspection of individual battery cells. “PouchStar” inspects the shape, size and seal seam of the cells and reliably detects surface defects, deformations, flaws and impurities.

Isra Vision has an inspection system series in its product range for the production of high-performance, safe and durable lithium-ion batteries that supports manufacturers throughout the entire process chain in detecting and eliminating potential problems and defects at an early stage and thus in meeting the highest quality demands. The “Smash Battery” system that belongs to the Smash product series has been optimized for the automatic inspection of electrode coatings as well as separator foils and their coatings. It provides real-time information on product quality and shows the extent to which the given specifications have been met. Possible material and product defects that may affect the quality of the final product can thus already be detected and classified in the early stage of battery production.

At the K 2022, the company will also be presenting a new turnkey solution for inline inspection of individual battery cells. “PouchStar” inspects the shape, size and seal seam of the cells and reliably detects surface defects, deformations, flaws and impurities. It also checks and documents the bar codes and data codes. This ensures that only flawless cells are delivered and thus helps to avoid costly recalls. If the worst comes to the worst, product qualities can be traced back in order to initiate process optimization measures.

A new system from the packaging sector will also be on show in Düsseldorf. DualStar optimizes the workflow in the production and finishing of flexible packagings. Thanks to the possibility of switching between ‘surface’ and ‘print’ inspection, depending on the job, it is the only solution worldwide according to the manufacturer to combine the inspection of unprinted films, laminates and coatings as well as printed material in a single system. This saves the converter or laminator investment costs, as he only has to decide on one system. The “surface inspection” component automatically detects and classifies all relevant defects in the production of unprinted, transparent, opaque, colored and translucent web goods. For printed goods, DualStar continuously checks the quality of the printed image, lamination and coating.
