Two-component eyeglasses as a hard/soft combination
The ALLROUNDER MORE machines are ARBURG's special series for multi-component injection moulding. They offer lots more space for moulds, rotary units, media connections and a usable ejector stroke as well as numerous optimised features for greater ease of use and simple maintenance. Precision is ensured by a highly dynamic electric toggle-type clamping unit with energy-efficient, liquid-cooled servo motors.
At NPE 2024, an ALLROUNDER MORE 2000 with 2,000 kN of clamping force and two electric injection units will process optical liquid silicone (LSR) and thermoplastic (PA). The two-component eyeglasses are produced in a 1+1-cavity mould in a cycle time of around 85 seconds. First, the vertical injection unit moulds the frame made of PA. An index unit then rotates the pre-moulded part into the second station. There, a horizontal injection unit adds the soft LSR lens. Part handling is performed by a Yaskawa six-axis robot.
