An apparatus for moulding lipstick or like products from a liquid moulding composition comprises a mould having one or more opentopped mould cavities 9, a duct 10 for the supply of heating or cooling fluid through its walls, an opening 66 in the bottom of the, or each, cavity, the opening being restricted to prevent the flow of liquid composition through it and means for supplying compressed air or other gas to the opening to blow a lipstick or like product moulded in the cavity 9 out of the open top of the cavity. The mould is rotatably mounted and has a series of cavities 9 arranged around the circumference of a wheel. The mould rotates so that each cavity is brought in turn to a filling station where liquid composition is poured into the cavity and heating fluid is passed through the duct 10, optionally to a further station where fluid at ambient temperature is passed through the duct 10, then to a cooling station where cooled fluid is passed through the duct 10 and finally to an ejection station. To eject the moulded product a piston 67 movable in a cylinder 68 below the mould is moved upwardly into engagement with the bottom of the mould around the opening 66 by compressed air, the compressed air then passes up the passage 81 in the piston 67 and through the opening 66 into the mould cavity 9. A holder 64 in a guide 62 is located above the open top of the cavity 9 at the ejection station so that the product is ejected directly into the holder 64. The supply of the different temperature fluids is controlled by a rotary valve the circular surface of which has inlet and outlet ports for different temperature fluids extending around different arcs of its periphery. A circular gutter extends around the mould through the tops of the cavities 9 and a scraper is provided so that excess solidified composition is scraped off and rejected.
