The unit ensures that the upper ejector plate stops when reaching the core plate, and the rear plate continues until it reaches the upper plate, the supplier said. As the assembly of the units is not in the centre of the mould, but within the ejector frame, the space required for installation is drastically reduced, the company reported.
The company also offers its Automatic Dog Lifter. Designed to function with just one set of ejector plates, the lifter saves machining costs and reduces the size of the mould, according to Cumsa. The component allows for undercuts of up to 32mm with a stroke of just 56mm. In addition, the device also offers the possibility for employment without the limiter using two sets of ejector plates. This system also gives users the capability of designing their own inserts, according to the supplier.
Cumsa also supplies devices for forming vacuums in the mould to improve processing and part quality.
