Family-owned Trief Maschinenbau GmbH develops machines, plants and systems for slicing food items. Utilising lubrication-free and maintenance-free products from polymer specialist Igus, their machines offer lubrication-free slicing. By Lars Braun, industry manager packaging, Igus cologne
The 3D print material iglidur I150 developed by motion plastics specialist igus has now been approved for food contact according to EU regulation 10/2011. By the certification of this Tribo-Filament that has a versatile use, customers can now print their custom-made parts which are approved for direct contact with food or cosmetics in moving applications.
The material is lubrication-free, maintenance-free, has a high wear resistance, and can be used on any 3D printer where the nozzle temperature can be set to 250 deg C. Since the high-performance plastic has a very low shrinkage, it can also be processed on 3D printers that do not have a heated printing plate. In this case, the igus adhesive film is recommended as the base for the print bed in order to ensure good adhesion.
The R4.1L series of enclosed energy tubes by Igus are available with a high-temperature option, enabling them to designed for contact with hot chips up to 850 deg C.
Made of high temperature resistant plastic, the chips do not stick to the tubes or burn into the material, and the enclosed design further allows these cable-friendly tubes to particularly suit applications in the machine tool industry, even within the working area of machines.
The R4.1L series offers torsionally stable, enclosed and light energy tubes, and with openable lids, filling with cables and hoses is made easy and fast.
Under its ball and spherical bearing series, Igus offers plastic products that are both lubricant-free and detectable. These guarantee that no lubricants or plastics enter the production chain during operation or in the event of a system failure.
Easily traced with standard metal detection methods, the plastics can be used in rod end bearings, clevis joints, flange bearings, spherical bearings, and pillow block bearings.
Being lubrication-free, the plastics need not be actively lubricated, and further save costs as they are maintenancefree plain bearing materials. They are also compliant with the EC Directive 10/2011 and FDA specifications for repeated contact with food.
The iglidur A181 is a lubrication-free and maintenance-free plastic that offers manufacturers the ability to create consistently safe products by avoiding the need for lubricants.
Complying with EC Directive 10/2011 and also the US Food and Drug Administration specifications for repeated contact with food, the plastic uses non-metallic and RoHS-safe ingredients made of tribologically optimised base polymers, solid lubricants and fillers.
The material can be used in both bottling and packaging plants as it is ideally suited for rotary as well as pivoting movements, and can be ordered in more than 110 dimensions up to 50 mm diameter, with or without flange, and at an affordable price.
