Horizontal injection molding machine e-speed 280

servo-electricfor PETfor thin-walled parts

Overview
Direct processing of PET and rPET for thin-wall injection moulding. Developed and demonstrated at K 2022 in collaboration with ALPLA Group, Brink and IPB Printing. The ENGEL e-speed 280 is fitted with a new injection unit with increased injection capacity to enable direct PET/rPET processing in a single-step injection moulding process.

Machine series
Hybrid, high-speed injection moulding machine designed for demanding thin-wall applications and high cycle rates. Suitable for production of thin-wall containers and packaging components with PET/rPET compatibility and tool integration.

Application / Demonstration

• Direct processing of PET and rPET (demonstrated with 30% rPET)
• Thin-wall containers and packaging components
• In-mould labelling (IML) with side-entry IML integration
• Collaborative system solution with tooling and automation partners (Brink tooling; Brink side-entry IML)
