    摘要: Method for producing, by injection moulding, a plastic body (2) provided with localized protuberances (8), for example a garden furnishing article such as a table or chair, or a pot, consists of obtaining by injection moulding a first component (1) of said body (2) provided with localized fins (7), said component (1) having substantially the shape of said body (2) and presenting the fins (7) in positions corresponding with the desired protuberances (8) on said body, then overmoulding by injection moulding onto said first component (1) a second component (10) of said body (2) , which becomes fixed to the first (1) to hence define said body (2), said overmoulding covering the fins (7) and hence defining said body (2) provided with the required protuberances (8).

    摘要: On at least one of an inner surface 7 and an outer surface 8 of a cylindrical main body 2, which is porous and is formed of a PTFE resin, a resin other than the PTFE resin is coated to form a coating layer 5, which partially penetrates into through pores 6, whereby a cylindrical body 1 excellent in mechanical strength having the coating layer 5 that is not released can be obtained. The coating layer 5 is formed of a crosslinking resin, such as a fluorine resin and an imide resin, or a PES resin, whereby a cylindrical body 1 excellent in mechanical strength and heat resistance can be obtained. In the case where the cylindrical body 1 is used as a fixing belt, it is preferred that the coating layer 5 is formed only on the inner periphery 3, and the releasing property and the impregnation function with a silicone oil of the PTFE resin are utilized.
