The invention discloses a bimetal pipe sleeve vacuum sintering molding technology and a product thereof. The technology includes the following steps that firstly, powder is prepared; secondly, a base material casing pipe is prepared; thirdly, cold isostatic pressing is conducted; fourthly, sintering molding is conducted; and fifthly, machining is conducted, and the qualified bimetal pipe sleeve product is obtained. The technology steps are easy to achieve, cold isostatic pressing and vacuum sintering are reasonably combined, and therefore the bimetal pipe sleeve product high in alloy structure compactness and good in comprehensive performance is manufactured. The bimetal pipe sleeve vacuum sintering molding technology is suitable for sintering of various kinds of metal alloy powder of ion-based alloys, nickel-based alloys, cobalt-based alloys, Mo2FeB2 and Mo2NiB2-based metal ceramic and the like, and alloy structures high in compactness can be obtained; and compared with centrifugal casting, no requirement for fluidity of powder melt exists, the technology is suitable for various kinds of alloy powder, and influences of the workpiece size are small, compared with hot isostatic pressing, the technology is simple, the period is short, the cost is low, good economic benefits and social benefits are achieved, and wide application and popularization are facilitated.
