Moulds and bottle design
PET Technologies – Hall 7 | Booth 646
t is difficult to overestimate the role of the blow mould in making a PET bottle shine as if it were glass. And these are the moulds PET Technologies will bring to BrauBeviale.
PET Technologies’ manufacturing facilities span 9,000 m² and include over 140 metalworking machines, along with two dedicated R&D departments, supporting a complete production cycle. The moulds production site is equipped with 4- and 5-axis machining centers with CNC: Deckel Maho (Germany), Doosan (South Korea), Micron MILL (Switzerland). This infrastructure permits PET Technologies to produce moulds for all European brands of rotary blow moulding machines.
The company develops moulds with the help of Catia V5, a leading engineering and design tool. The company uses duralumin alloys, series 6000 of its hardness is up to 100 HB. The mechanical properties of this type of aluminium has an optimum ratio of hardness and plasticity for shock loads, says the company. Depending on customer’s preference, PET Technologies can anodise moulds, applying an electrochemical coating to the surface layer. It provides additional hardness, increases wear resisting properties and protects against corrosion. In addition, PET Technologies manufactures mould cooling units.
Mould base – key to innovations
PET Technologies developed a new Smart Base technology. Smart Base is designed to reduce air pressure requirements and streamline material distribution by minimising friction between plastic and mould surfaces. The core of Smart Base lies in its additional air ducts in the base, which lower pressure and redirect air swiftly, reducing resistance within the mould. Testing on automatic linear blow moulding machines showed impressive results: a 30% reduction in air pressure without any compromise on bottle quality. With compressors being a primary electricity consumer in blow moulding, Smart Base offers a clear advantage in energy savings – cutting costs while maintaining top-quality output, says the company.
PET bottle designs: old & new
PET Technologies offers a complete, turn-key bottle design solution that includes conducting in-depth market research, following global trends, creating comprehensive branding – from product naming to logos and labels – modifying bottle shapes to meet evolving needs, and adapting new designs to fit existing filling lines. Additionally, the company provides precise 2D drawings and 3D renders of PET bottles. With a strong focus on reducing bottle weight and optimising all APF-Max series machines for rPET, visitors are invited to find the inspiration to create something new at PET Technologies booth.
