A method of cyclic injection molding enables production of four or more products in each production cycle while the filling of each mold cavity may be separate and therefore may be fully controlled. Multicomponent products are molded in an injection molding system that includes a mold positioning system, a first injection system and a second injection system, and a left molding block, a right molding block and an intermediate molding block located between the left and the right molding blocks, with the blocks being disposed along a common axis for axial movement in respect to each other. The left molding block defines a first left general mold cavity part and the intermediate molding block defines a first left gated mold cavity part and a second left gated mold cavity part. The right molding block defines a first right general mold cavity part and the intermediate molding block defines a first right gated mold cavity part and a second right gated mold cavity part. The mold positioning system combines the molding blocks so that the first left general mold cavity part is connected with the first left gated mold cavity part to form a first left mold cavity, the first right general mold cavity part is connected with the first right gated mold cavity part to form a first right mold cavity, the first left general mold cavity part is connected with the second left gated and mold cavity part to form a second left mold cavity, which encompasses the first left plastic component, and the first right general mold cavity part is connected with the second right gated mold cavity part to form a second right mold cavity, which encompasses the first right plastic component.

A method of cyclic injection molding a multicomponent product in an injection molding system comprising a mold positioning system, a first injection system and a second injection system, and a left molding block, a right molding block and an intermediate molding block located between the left and the right molding blocks, said blocks being disposed along a common axis for axial movement in respect to each other, the left molding block defining a first left general mold cavity part and the intermediate molding block defining a first left gated mold cavity part and a second left gated mold cavity part, the right molding block defining a first right general mold cavity part and the intermediate molding block defining a first right gated mold cavity part and a second right gated mold cavity part, the intermediate molding block defining a first runner system and a second runner system connected to said gated mold parts, the method comprising the steps of (a) combining by the mold positioning system said molding blocks so that the first left general mold cavity part is connected with the first left gated mold cavity part to form a first left mold cavity, (b) injecting by the first injection system via the first runner system a first fluid plastic material into the first left mold cavity, and solidifying the material to produce a first left plastic component, (c) separating by the mold positioning system the right and center molding blocks, (d) combining by the mold positioning system said molding blocks so that the first right general mold cavity part is connected with the first right gated mold cavity part to form a first right mold cavity, (e) injecting by the first injection system via the first runner system first fluid plastic material into the first right mold cavity, and solidifying the material to produce a first right plastic component, (f) separating by the mold positioning system the left and center molding blocks, retaining the first left plastic component on the first left general mold cavity part, (g) combining by the mold positioning system said molding blocks so that the first left general mold cavity part is connected with the second left gated mold cavity part to form a second left mold cavity, which encompasses said first left plastic component, (h) injecting by the second injection system via the second runner system a second fluid plastic material into the second left mold cavity so that the second fluid plastic is united with the first left plastic component and solidifying the material to mold a first left multicomponent plastic product, (i) separating by the mold positioning system the right and center molding blocks, retaining the first right plastic component on the first right general mold cavity part, (j) combining by the mold positioning system said molding blocks so that the first right general mold cavity part is connected with the second right gated mold cavity part to form a second right mold cavity, which encompasses said first right plastic component, (k) injecting by the second injection system via the second runner system second fluid plastic material into the second right mold cavity so that the second fluid plastic is united with the first right plastic component and solidifying the material to mold a first right multicomponent plastic product, (l) separating by the mold positioning system the left and center molding blocks, to eject the first left product molded in step (h), wherein step (c) comprises the step of (m) ejecting a first right product molded in step (k) of the preceding molding cycle.
