In Britain, the earliest application of lost foam casting is the British cast steel research and Trade Association, whose method is called the replicate method, which has been reported since 1982. The act has two options:

- The first method is called replicate FM method. Put the foam polystyrene plastic mold together with the pouring system into the sand box, fill it with sand, and then vibrate and compact it. The vacuum of -300-380mmhg is pumped into the mold, and then the molten metal is poured into it. The advantages of the gasification mold casting method and the vacuum molding method are used at the same time, which has great potential in the production of iron castings below 20 tons.
- The second method is called replicate CS method, which is used to produce high-quality low-carbon steel castings and other alloy parts that are sensitive to the interaction process with polystyrene decomposition products. When using this method, as in investment casting, 4-5 layers of ceramic coating are painted on the polystyrene foam mold with high density (40-48g/i), and the shell thickness is 3.2-4.7mm. After the thin shell is sintered and the gasification mold is burnt out, the shell is put into the sand box, and the sand is added to vibrate and compact the shape. During pouring, the vacuum of -300-380mmhg is pumped into the sand box. This process can produce precision and high-quality steel castings of various grades. The surface roughness of the castings is ≤ 12.5mm, the dimensional accuracy of the castings of 2.5-100mm is 0.25mm, the dimensional accuracy of the castings below 300mm is 0.75mm, and the dimensional accuracy of the castings below 600mmm is 1.5mm. The machining allowance of the above castings is 1.6-3.2mm.
