MOULD MAKING PETplanet Insider Vol. 26 No. 04/25 www.petpla.net 32 Advanced blow mould solutions Client-centric approach The PET bottle industry is constantly evolving, driven by the demand for more efficient, sustainable, and cost-effective solutions. One of the most crucial areas of innovation is blow mould technology. As clients demand change, moulds must adapt, integrating new advancements to enhance production efficiency, reduce costs, and improve sustainability. At the forefront of these developments are rotary and linear moulds, the backbone of PET bottle manufacturing. PET Technologies has 26 years of experience in the development of blow moulding machines and blow moulds. It offers tailor-made solutions for the needs of modern production lines. The company owns a 9,000m² state-of-the-art facility dedicated to blow moulding machines and moulds, equipped with 140+ metalworking machines and a specialised mould R&D department. 5-axis CNC machines enable the production of moulds for precision finishes and engravings, compatible with all major European blow moulding brands. PET Technologies’ mould sizes range from 100ml to 40 l. Whether it’s a 30 l PET keg, a 5-gallon water cooler, or a 10 l oil bottle with a handle, PET Technologies offers customised solutions to meet diverse client needs in large bottle volumes. Enhanced durability with anodisation Anodisation is an electrochemical treatment that enhances durability by improving hardness, wear resistance, and corrosion protection, extending mould lifespan. PET Technologies offers black anodising upon client request, providing an additional layer of oxidation that further enhances resistance to wear and thermal stress. Unlike standard anodisation, black anodising absorbs more heat, making it particularly beneficial for high-temperature applications. Cooling for consistent quality Efficient cooling is essential for maintaining optimal blow moulding performance. PET Technologies says that its machines are equipped with specialised cooling units designed to regulate mould temperature, ensuring consistent bottle quality and faster cycle times. Inserts: flexible solutions Bottle design varies widely, with the only real limits being imagination and physics. When a client wants multiple interchangeable design elements, inserts provide a good solution. These allow for quick design modifications without the need for an entirely new mould, offering cost savings, flexibility, and faster production adjustments. Smart Base - The key to sustainability PET Technologies offers the intelligent Smart Base mould technology which claims to significantly improve the blow moulding process. It is designed to reduce the main blow mould pressure by increasing the number of air exhaust channels between the bottom of the blow mould and the preform. The blowing pressure reduction by 32%, this results in the reduction of energy and CO2 by 25%. Deep Grip technology The Deep Grip technology is an alternative to traditional PET bottle handles. Conventional handles are separate plastic pieces, adding complexity to logistics, costs, storage, and the bottle’s integrity and shape. Deep Grip technology eliminates these challenges by integrating a deeper, ergonomic grip directly into the bottle design - and, consequently, into the mould. The company says that this technology not only simplifies the manufacturing process but also enhances user experience, making bottles easier to handle while maintaining structural integrity.
