Title: Expanded polymer model moulding procedure - filling mould with polymer balls after fitting insert and expanding these with aid of steam to fill mould
Inventor: ERIC LENOIR
IPC: B22C9/04
Filed: 1992-11-23
Abstract: The procedure consists of making a model (M) of expanded polymer in a mould (2) which has a recess (3) to receive an insert (1) which is to be incorporated in the metal component moulded in the shape of the model. After fitting the insert, which can be held in place by suction, the mould is filled with polymer balls which are expanded by means of steam fed through jets or pores in the mould so that the expanded polymer fills the interior of the mould. The steam is stabilised at a pressure of 120 deg.C and a pressure of about 3 bars to ensure a homogeneous treatment of the polymer balls. Once the polymer mould has been made it is cooled, and it can then be used in a sand mould for making a metal component, vaporising as the molten metal is poured into the mould. USE/ADVANTAGE - Mfr. of metal components by lost model technique. More precise model shape, so that component needs no machining after moulding.
