Haidlmair
Haidlmair Tool GmbH, a specialist in tools for logistics and disposal containers has commissioned new production capacities for extra large parts and the assembly of extra large injection moulds. The group’s mould making options now cover the entire size range from the slip box to large waste bins with a mould weight up to 120 tonnes. These new capabilities will be at the centre of the company’s presentation in Hall 12 at K.
Haidlmair moulds incorporate compactness gained from a design that is said to optimise power distribution within the mould system itself.
The basic principle is the indentation of the container exterior through a 4-sidecore system with the separation lines along the container corners. The outer side cores are located on the fixed mould side and are locked within the mould assembly on both sides in a tapered holding frame with wedge-shaped cross-section, where they are simultaneously centered and fixed. With that system a high percentage of the lateral pressure applied on the side cores is transmitted to the adjacent mould structure. This mould construction consists of a minimum of platens and components and allows for a minimum shut height and cross section.
In Hall 15 Engel will be moulding the “S + Smart Cube”, a special container developed under the project management of Haidlmair in cooperation with raw material producer Borealis, measurement technology company HDEMC, hot runner manufacturer PSG and in-mould label manufacturers Viappiani and Engel itself. The design object features large label areas on all four sides, surrounded by a space frame structure in paper crease (pictured).
In addition to the 4-sided labelling application, the gas-injection technique will be applied to compensate shrinkage and increase precision in upper body structure. This is said to be achieved through eight specifically incorporated hollow local areas along the upper container rim with the four gripping areas. Haidlmair claims that the cooperation project is “the current state of the art in container moulding.” It will be moulded on an Engel e-duo 5440/700 (with 700 tonnes of clamping force).
A second demonstration of a Haidlmair mould will also take place at Wittmann Battenfeld’s stand in Hall 16. A Battenfeld HM 300/2250 ServoPower will produce a hockey stick from glass fibre reinforced PP. Again, Haidlmair’s gas injection technology will be used, as the 120 cm long handle of the hockey stick is a lightweight hollow profile.
