Balometer Mould Tooling
We spent eight months re-designing; prototyping and testing these Balometer parts until we had a design that delivered the results expected of it in the field and would lend itself to toolmaking and the injection moulding process.
Running a mould flow analysis on the 330mm diameter part was the first step in the mould design process. It aided material processing and hot tip feed selection.
The tool design covered moulding an M10 internal thread and 14 side actions, including six 4mm diameter 150mm long water cooled core pins, which hollowed out the main spokes.
Detachable hydraulic cylinders and slider units were designed so they could easily be removed by the mould setter. This enables us to build the tool in the press without the aid of a skilled toolmaker, increasing flexibility and saving money.
The hardened tool weighs 1350kg and measures 1.5m across with the 6 hydraulic cylinders in place.
The below mouldflow was conducted to see if this part would fill successfully with a two drop hot runner feed – The answer yes.
