K2025 | EXHIBITION PREVIEW
other side of the mould, Clearmelt is used in the same mould to cover the surface with polyurethane (PUR) – creating an in-mould coating. This gives the part a transparent, scratch-resist- ant surface layer in a single production step. Combining these process steps in a single cycle eliminates the need for costly hardcoating. The PUR layer protects against yellowing caused by UV exposure. The production cell at K2025 is based on an Engel Duo two-platen machine with 7,000kN clamping force and a vertical rotary table. A new version of the Viper 40 linear robot is integrated for part removal. The company will also run an automated production cell in which gas diffusion layers (GDLs) for fuel cells are encapsulated with a liquid silicone rubber (LSR) seal. This shows how sensitive functional elements made of film material can be overmoulded with LSR. The GDL foils are integral components in fuel cells and must be sealed with high precision without impairing their diffusion function. The core element of the cell is a vertical Engel Insert 150 injection moulding machine with 1,500kN clamping force and an integrated rotary table. This enables simultaneous injection and demoulding, nearly doubling the output with a cycle time of 50 seconds.
Moulding is performed with a two-cavity mould concept from ACH Solution. Equipped with the ACH Servoshot 2G and its electric nozzle control, it ensures

high process reliability and part quality, even with multiple injection points. An Easix articulated robot handles all part manipula-
tion. In the first step, it removes the GDL films from the feeding system and positions them in the front station of the rotary table
mould. After rotation, injection takes place in the rear station, where films are partially overmoulded with a thin LSR seal. Finished parts are then removed, and new films inserted. An integrated camera inspection system verifies the wall thickness distribution of the LSR seal. Engel will also use a tiebarless Victory 180 machine with a clamping force of 1800kN to produce
Lower Color Consumption and Maintain Color Quality
• Detects minor color deviations (ΔE) in real time
• Automatically adjusts color to maintain color specs
• Reduces scrap and downtime • Eliminates line operator QC involvement
