Tiebarless

The new Vemix SC 80 tiebarless injection moulding machine developed by Presma, based in Gornate Olona (Varese, Italy), features a C-frame clamping unit (80 tons) and a vertical injection unit. Thanks to the absence of tiebars and its vertical orientation, the mould-holder plates (700 x 400 mm) and the opening stroke (470 mm) offer great freedom of movement especially in the production of components with bulky inserts.
One of the notable features of the clamping unit is the movable plate which slides on 2 guides with recirculating spheres. This ensures an optimal planarity during the approach and closing of the moulds.
