Small series-capable injection moulding tools for processing thermoplastics are not ground or eroded, but created using a resin compound. In this process, a stereolithographic original model is embedded in an epoxy resin-aluminium mixture and the resulting form is stabilised with a supporting frame.
A basic prerequisite of this procedure is a tool construction carried out previously, which takes into account the establishment of the mould parting line, the planning of the later mould release with the associated establishment of possibly needed loose parts for the exposure of undercuts, the bringing in of mould inclines, the planning of gating and de-aeration, as well as the positioning of the knock-out pins.
Delivery time for a resin tool is usually around 10-12 days.
