Abstract
1387300 Making reusable mandrels; cores UNION CARBIDE CORP 23 June 1972 [24 June 1971] 29455/72 Headings B3A and B3F [Also in Divisions B2 and C7] A mandrel for use in producing castings or plasma-deposited bodies having zero degree draught or re-entrant geometries comprises a base material of melting temperature above 650 C., a coated metallic alloy layer of melting temperature below 700 C., and lower than the melting temperature of the base material and a second coating of a neutral plastics composition having a higher melting point than the alloy. The base material is of aluminium, brass, steel or copper. The alloy coating which is <SP>1</SP>/ 16 to 1 inch thick and may be applied by spraying, brushing, casting or painting, includes at least one of Bi, Pb, Sn, Cd, In or Sb. The plastics coating is of polyimide, especially one derived from pyromellitic dianhydride and an aromatic diamine. The base mandrel may have locking grooves or projections to increase securement of the alloy. After deposition of the alloy, the mandrel may be machined to conform it to the contour of a body to be produced thereon. The plastics coating may be roughened by grit blasting to improve adhesion to the material to be formed thereon. In the examples, free standing beryllium bodies are prepared by plasma deposit - ing Be powder on the coated mandrel heating the sprayed mandrel in an oven to melt the alloy layer so as to enable the mandrel to be removed and peeling the polyimide film from the beryllium structure. The mandrel can then be recoated for reuse.
