    摘要: A method for producing a twin screw cylinder provided with or having a wear-resistant coating, in which two bores, which extend essentially parallel to each other and overlap each other, are produced in a cylinder and then two liners are inserted into the bores, the liners having an essentially C-shaped cross-section, continuing from each other in the overlapping region of the bores, forming the inner surface of the bores, and serving as a wear-resistant coating. First, a tubular liner is inserted into a first bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the other bore and after this, a second tubular liner is inserted into the second bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the inner surface in the first bore formed by the first liner.

    摘要: First screw (11) and second screw (12) each have small diameter portion (17a) having a diameter smaller than that of flight tip (11a, 12a), an axial position of small diameter portion (17a) of first screw (11) being the same as that of second screw (12), the present invention including first screw supporting portion (15a) having first supporting surface (25a) and second supporting surface (25b) that rotatably support small diameter portions (17a) of first screw (11) and second screw (12), and flow path (25c) through which resin material, which is transported by first screw (11) and second screw (12), passes.In the radial direction of first screw (11) and second screw (12), clearance Δ, which is formed between small diameter portion (17a) and each of first supporting surface (25a) and second supporting surface (25b), is equal to or less than the clearance, which is formed between flight tip (11a, 12a) and an inner surface of cylinder (13).
