A bumper strip for a vehicle may include an upper surface portion forming an upper surface, a rear surface portion downwardly extending from the rear end portion of the upper surface portion and accommodated on a hood seating portion of the bumper, a matching portion cover of a shape extending in the rearward and downward directions from the rear surface portion, and a side surface portion forming a side surface, and wherein the upper surface portion, the rear surface portion, the matching portion cover and the side surface portion are integrally formed.

A multi-material molding apparatus and method includes a single mold having, within a mold cavity, one or more movable partitions that segregate at least first and second molding materials. The first molding material is processed to form a first molded portion of the multi-material part. The second molding material is then flowed, through the movable partition, into contact with the first molded portion. That second molding material is then solidified to form a second molded portion of the multi-material part.

A method of injection molding thick plastic parts, comprising molding a transitional part using by a first shot through the first or A-side of the mold, moving the transitional part and mold core away from the mold cavity to create a second shot space, and injecting a second shot which merges with the transitional part to create a final part.

The invention relates to a method of manufacturing a heart valve, comprising: a step of injection moulding a first part (110) of the heart valve from a first block-copolymer, wherein the injection moulding is performed at a temperature below an order-disorder transition temperature of the block copolymer, such that a phase structure is present in the molten block-copolymer; a step of injection moulding a second part (114) of the heart valve from a second block-copolymer that is different to the first block-copolymer, by over-moulding over the first part (110) to form an over-moulded structure, wherein the injection moulding is performed at a temperature below order-disorder transition temperatures for the first and second block copolymers, such that a phase structure is present in the molten second block-copolymer and remains present in the first block-copolymer; and a step of cooling the over-moulded structure, without heating it above the order-disorder transition temperatures between the step of injection moulding the second part (114) and the step of cooling, so as to preserve an arrangement of the phase structures created during the steps of injection moulding and produce anisotropic physical properties in the second part (114). The invention also relates to the thus manufactured heart valve.

An injection molding apparatus according to an embodiment is configured to mold a thermoplastic resin into a thick-walled component by injection molding. The injection molding apparatus includes a mold having a cavity and a core; and a controller configured to control an operation of the mold. The controller is capable of performing a filling and pressure holding process of filling the thermoplastic resin between the cavity and the core in a state in which a distance between the cavity and the core is increased, and a cooling and solidifying process of cooling and solidifying the filled thermoplastic resin while pressurizing the filled thermoplastic resin by decreasing the distance between the cavity and the core. The controller stacks the thermoplastic resin by performing an operation set including the filling and pressure holding process and the cooling and solidifying process a plurality of times.

A footwear article forming process, and a device for the same are disclosed. The process includes: providing a forming mold set including an outer modular mold, an inner formation mold, and a footwear-forming space therebetween. The footwear-forming space comprises a footwear lower portion forming space and a footwear main portion forming space. Footwear article forming steps are as follows: injecting a pre-determined amount of a footwear main portion rubber material into a footwear main portion sprue channel, the footwear main portion rubber material being injected from a footwear main portion rubber injection opening into the footwear main portion forming space via a transfer injection channel; and placing a footwear lower portion rubber material into the footwear lower portion forming space.

A method for producing a component, and an injection-molding device. In the method. the following steps are carried out, in particular in succession: closing an injection mold, injection molding a base body by introducing a first plastic material into a first injection-molding cavity, opening the injection mold, stamping one or more first film elements and removing the component from the mold.

A method for producing a vehicle rear module that includes: a clear member monolithically including a lamp section and a window section; and a colored member for shielding at least part of a vehicle interior from the exterior. The method for producing the vehicle rear module comprises: a step for injecting a transparent resin from a single resin injection hole into a first cavity to form the clear member; and a step for injecting a colored resin from a plurality of resin injection holes into a second cavity to form the colored member.

An injection mold for a high-aspect-ratio double-layer cylindrical plastic part and a molding method using the same. The injection mold includes a support base plate. A movable mold fixing frame and a movable mold base plate are arranged at the middle of a lower surface of the support base plate through positioning screws. A lower core mold is matchingly provided at a center of an upper surface of the support base plate, and is provided with a lower semicircular cavity for accommodating an outer die barrel. One side of the lower semicircular cavity is open, and the other side is provided with a first end wall which is provided with a lower semicircular notch for an inner die rod to pass through. An upper surface of the lower core mold is provided with a positioning protrusion, a lower feeding groove, and a remaining groove.

A mechanical interlock pin assembly includes a shaft having a first end and a second end. The mechanical interlock pin assembly includes a set of helical spline elements disposed at the first end of the shaft, the set of helical spline elements extending along a longitudinal axis of the shaft. The mechanical interlock pin assembly includes a bearing rotatably coupled to the second end of the shaft, the bearing configured to allow rotation of the shaft between a first rotational position and a second rotational position relative to a mold cavity.
