EVENT PREVIEW PETplanet Insider Vol. 26 No. 07+08/25 www.petpla.net 46 50 years of PET bottle blow moulds From sketch to smart bottle designs The mould manufacturing of blow moulds for PET bottles at Röders GmbH started exactly 50 years ago. The family-owned company traces its origins even further, founded two centuries earlier as a pewter casting handcraft shop. Today, with 400 employees at its main facility in Soltau, Germany, Röders offers a one-stop, single-source solution for design, manufacturing, sampling, and testing. At drinktec, the company will showcase its latest moulding developments, in-house competences, services, and long-standing legacy in the PET sector. As an independent mould supplier, Röders has its own mould design and engineering departments. The moulds are made on high-speed milling machines that are themselves developed in-house. They reflect the trend for higher speed manufacturing and are equipped with the latest operating software. The moulds are designed to run seamlessly on rotary or linear stretch blow moulding machines from KHS Corpoplast, Krones, Sidel, Sipa and others. The Röders in-house laboratory has been certified by PepsiCo for many years and was recently authorised by Coca-Cola. Trends in the bottling industry Trends like lightweighting, sustainability, cost-effectiveness and efficiency influence the contemporary bottling industry. Röders focuses on developing solutions that meet and even exceed these evolving market demands and combines its expertise with advanced technology to create customised mould solutions that optimise bottle performance and production efficiency. At drinktec, Röders will exhibit a diverse array of blow moulds for various applications, featuring blow mould halves and base units tailored to a wide range of beverages and liquid food. Visitors can expect to see moulds with unique contours, including specialised engravings and surface structures that demonstrate both technical and design capabilities. Single source solution Röders offers a single source for design, manufacturing, sampling and testing and maintains that its integrated approach means that it can offer short reaction and lead times, as well as avoiding compatibility issues. Customers can bring a rough sketch, a sample or a complete 3D file; the company says that its designers will then create a visually appealing and convincing bottle drawing and design a finished product that meets all technical requirements and will run smoothly in the stretch-blow process and on conveyor lines. To help visualise new bottle designs, Röders produces 3D prints in various colours using its own in-house 3D printer. These colour prints are tailored to customer requirements and are valuable tools during early-stage design discussions. At the customer’s request, Röders tests the bottle design in its ISO 9001-certified laboratory to ensure high industry standards. Sample bottles in various sizes, colours and complexity levels, ranging from simple contours to medium and highly intricate shapes, including examples with engraved logos and textured surfaces, will also be on display. Accelerating time to market Using modern production, in-house high-speed machining technology and a management structure that is focused on performance and customer satisfaction, Röders says that it can deliver moulds in very short time. If required, it can combine special coatings and quick-change systems for moulds to increase durability and provide added value by reducing downtime and extending mould lifespan. The company supports customers with on-site process and machine optimisation, helping to ensure smooth transitions to new bottle designs, whether working with standard PET or rPET. Energy efficiency and sustainability The company will also showcase its proprietary low-pressure base designs, developed to reduce blowing pressure and energy usage. Originally engineered for CSD bottles, these base solutions are now also available for base designs for still beverages. The team fine-tunes blowing parameters for weight reduction, energy efficiency with low-pressure blowing and optimised stretch ratios for improved material distribution. www.roeders.de Röders Hall C6 – Booth 432
