Complex: multi-component application
As a trade fair application, an electric ALLROUNDER 470 A will produce holding brakes made from 30% glass-fibre-reinforced PBT and a 70 Shore A hardness LSR component on an 8+8-cavity mould. First, the thermoplastic component is injection moulded without a sprue via a hot runner. The pre-moulded part is rotated in the mould via an indexing unit. The LSR component is then moulded on via a cold runner. For this purpose, a second, external piston-type injection unit is used, which is bolted directly onto the mould. In this manner, eight holding brakes, each weighing 0.38 g are produced in a cycle time of 40 seconds. The LSR component share here is only 0.03 g.
