Title:
METHOD FOR PRODUCING MOULDS AND CORES SUITABLE FOR PRODUCING FIBRE COMPOSITE BODIES OR CAST PARTS IN METAL OR PLASTIC, MOULD BASE MATERIAL AND BINDER USED IN THE METHOD AND MOULDS AND CORES PRODUCED ACCORDING TO THE METHOD
Document Type and Number:
WIPO Patent Application WO/2019/137871
Kind Code:
A2
Abstract:
The invention relates to a method for producing moulds and cores suitable for producing fiber composite bodies or cast parts made from metal or plastic from a particulate mould base material and a multi-component binder by means of 3D printing. According to the invention, the particulate mould base material is pretreated with at least one silicon-organic compound which has a polar hydrophilic end and a non-polar hydrophobic end. After forming a layer from the pretreated particulate moulding material, the binder or at least one component of the binder is applied to the layer in liquid form. The organosilicon compound is contained in moulds and cores produced according to the method. The mould base material and the silicon-organic compound can be part of a set used for carrying out the method.
