Abstract: The invention is directed to a process to manufacture an interconnected stack of thermoplastic frames having two sides by stacking the thermoplastic frames to obtain a stack of frames such that the facing sides of two neighbouring frames are in contact with each other at a contact area. When stacking a longitudinal conduit is formed which runs along the length of the stack and a branched conduit is formed at the contact area. The interconnected stack of thermoplastic frames are obtained by supplying a pressurised melt of a plastic material to the elongated conduit and branched conduits.

Abstract: In various examples, a printbar is formed from multiple modular fluid ejection subassemblies joined together through a molding process that provides for a continuous planar substrate surface. A mold may secure the modular fluid ejection subassemblies during a molding process in which a runner conveys a molding material to seams between the joined modular fluid ejection subassemblies.

Abstract: A method is provided for producing a multi-section plastic component in which a first plastic injection-molded individual part and a second plastic injection-molded individual part are formed. The plastic injection-molded individual parts are joined by injecting a plastic moulding compound. The plastic molding compound is a non-elastomeric thermoplastic and forms a plastic connecting component following a curing process. The plastic injection-molded individual parts and plastic connecting component are then at least partially painted.

Abstract: A method and assembly for injection molding a part. The injection molding assembly has a frame and a core back assembly on the frame with a material controlling region. The core back assembly has first and second states with the material controlling region: i) in a first position with the core back assembly in the first state; and ii) in a second position with the core back assembly in the second state. First and second mold units are configured to be placed in operative relationship on the frame wherein the first and second mold units cooperate to form a mold cavity on the frame. The frame, core back assembly, and first and second mold units are configured so that the state of the core back assembly is changed as an incident of the first and second mold units being placed in the operative relationship.

Abstract: The invention relates to a retaining device (5) for a rotatable center block (17) in an injection molding device (1), comprising a lower rotary plate (14) rotatable about an axis of rotation (13) and driven by a motor (15), the lower rotary plate being used for retaining the rotatable center block (17). The retaining device (5) comprises a lower cross member (7), which is mounted movably in the longitudinal direction (x) on guide rails (9) while supported on a machine bed of the injection molding device by means of first bearing blocks (8). The retaining device (5) can have two bearing blocks (16), by means of which the lower cross member (7) is supported in the circumferential direction relative to lower beams (4) of the injection molding device. For a further increase in efficiency, the center block (17) has a main body made of a material of lower density than a coupling plate (23) operatively connected thereto.

Abstract: It is described a method and an apparatus for injection co-mould and assemble plastic material objects having a first part provided with a hinge pin, and a second part provided with an annular element suitable to be coupled in an articulated manner. The apparatus includes a mould having separated moulding impressions for the two parts to be moulded; a first moulding pin element defining the pin impression and a second moulding pin element defining the annular element impression are provided. The apparatus includes cooling means; particularly the first pin element is internally provided with a channel and a tubular element, being coaxially arranged and defining a cooling gap. A cooling fluid flows through the tubular element and the gap.
