Inspection systems for the plastics industry

Reliable, precise and user-friendly Metal detectors and separators from Mesutronic Why detect foreign bodies? Despite all safety precautions, the contamination of plastics with metals is unfortunately a problem in every manufacturing company. The effects are often dramatic if these are not reliably detected and removed from the production chain. Damage to crushing systems, injection moulding machines and extruders or the loss of supplier contracts are often the result of inadequate control systems. Why Mesutronic? For more than 30 years, we have been developing inspection systems with and for...

Incoming goods area In the incoming goods area, metal detectors and metal separators are used to check the emptying of lorries and big bags in free fall or in pneumatic conveyance. In conjunction with conveyor belts, they can also be used for examining granules, powders or masterbatches in 25 kg bags. This allows contaminants to be traced back directly to the supplier. Type P-TRON 05 GM separators are available in nominal diameters of up to 200 mm. This makes them ideal for use in silo feeders or for the main distribution system after the silo. They can be used for both the pressure and vacuum...

Production und process The protection of the production process is the core task of metal detectors in the plastics processing industry. Here, it is important to optimize service life and produce qualitatively homogeneous end products and semi-finished products. As a rule, only separators are used here. These remove metals with minimal material loss without interrupting the production process. Similar to its big brother the P-TRON GM, the P-TRON 03 FM is used in pneumatic conveying lines with so-called »lean phase« conveying. In contrast to the P-TRON GM, however, it is not equipped with pinch...

Outgoing goods area The quality of the outgoing products is checked in the packaging area. This exit check also monitors whether damage such as abrasion or breakage to the tools of the shaping machine has occurred during the forming process. This avoids costly waste and loss of time, especially in the case of fine cavities in injection moulding. The METRON 05 FlatLine metal detector coil is integrated into the discharge shaft or the discharge belt of the injection moulding machine. This system provides sufficient detection power to detect even parts of broken tool pins. The strong shielding even...

Material recycling For optimal value creation, it usually makes sense to return your own production waste to the material flow as quickly as possible. This can be done within the machine itself or in central processing areas. The work location of the METRON 03 SL is the feed belt of the auxiliary mill of an injection moulding or blow moulding machine. As a rule, small parts or hollow bodies are again crushed and fed directly to the production machine. Here, the SL protects against machine parts that could have detached themselves from the complex production machines. The stand-out aspect of the...

For particularly large material heights, such as the grinding of large tanks or film bundles, it may be necessary to switch to closed tunnel detectors of the METRON 05 C series. These have a higher detection performance and can also be equipped with so-called »shielding extensions«. This massively reduces false alarms caused by electromagnetic interference fields, which can cause a sharp reduction in detection accuracy, especially at clearance heights above 800 mm. To protect against the entry of finer metal parts or to protect a powder mill, it is recommended to use a QUICKTRON 03 R metal separator,...

Digital products and services The successful operation of inspection systems is no longer solely dependent on purchasing of the right product, but also on how well the system is connected to the people and machines in its environment. Mesutronic offers a wide range of support services that increase the integration of our products. Depending on the type of electronics used, our systems can already provide information as standard via analogue signals, various bus systems or Ethernet. Information is received by either controllers, process control systems or other, higher-level machines along the...

mesuREMOTE allows our service specialists from Kirchberg im Wald to access any connected system, often avoiding time-consuming on-site deployment. Communication is secured according to current IT standards, encrypted and takes place solely after approval by the customer at all times. All of this can additionally be secured on the hardware side via a key switch. This means that any uncoordinated manipulation of systems by Mesutronic or third parties is reliably excluded. The electronic autoTEST tester allows significant reduction in manual test cycles in devices of the 07 electronics series. Signals...

In order to reduce introduction barriers and ensure smooth, long-term operation, we recommend our training programmes. We offer a wide range of solutions, from simple operator training included with commissioning to multi-day events on our premises. As with our physical products, we strive to make training as efficient and economical as possible for our customers while still in the coordination phase. The content is recommended by us and then individually adapted to your needs according to the number of participants, their educational background or previous experience. We are also happy to offer...

Customer-specific projects Special challenges may arise in particular when retrofitting inspection systems into an existing production environment. The development of solutions for these tasks is one of the core competencies of Mesutronic GmbH. The ways shown range from simple consultation on the deployment of a standard solution in an unusual way, through smaller and larger modifications, to the complete, customised customer system. We focus on the permanent, reliable and economically optimal fulfilment of your requirements. This is made possible by our company‘s competent team of employees,...
