Injection molding plastic parts includes furnishing resin material to a screw barrel having a rotatable screw therewithin, rotating the screw to work the resin material into a molten state, furnishing additive such as liquid color or another additive to the screw barrel interior at a first rate during screw rotation and driving the screw longitudinally from a first position to a second position to force an additive-resin material mixture resulting from screw rotation into a mold while furnishing additive with resin to the screw barrel interior at a second additive addition rate.

A molding unit has a first molding station having a first mold having a first mold cavity, a second molding station having a second mold having a second mold cavity, a transfer unit having a support and at least a first core extending from the support. The transfer unit is arranged for moving the first core into a first molding position at the first molding station and into a second molding position at the second molding station. The first core extends into the first mold cavity when the first core is in the first molding position and into the second mold cavity when the first core is in the second molding position. A core actuation unit is arranged so that at least at the first molding station the first core is moved relative to the support from a first core position into a second core position when the first core is moved into the first molding position.

This injection molding method uses an injection molding machine for two-material molding, which comprises a first mold part that is provided with a cavity and a second mold part that is provided with a cavity and is arranged in tandem with the first mold part. This injection molding method comprises: a first molding step wherein a material is injected into the cavity of the first mold part and the material in the cavity is compressed; and a second molding step wherein a material is injected into the cavity of the second mold part. A pressure, which is generated in the second mold part by injecting the material into the cavity in the second molding step, acts on the first mold part, and a compressive force is applied to the material in the cavity in the first molding step.

There is provided a liquid supply member capable of suppressing deformation of a liquid supply path and decrease in sealing property of a liquid supply path, during molding, and a manufacturing method of the liquid supply member. For that purpose, in die-slide injection molding that combines two components, a protection portion that protects a part of one component easily affected by heat and pressure, is provided on the other component.

A platen apparatus for a mold center section of an injection molding machine includes a first mold mounting surface on a first front face of a first wall, the first mold mounting surface for supporting a first mold section, and a second mold mounting surface on a second front face of a second wall, the second wall spaced apart from the first wall in an axial direction and providing a generally hollow chamber therebetween. The second mold mounting surface is for supporting a second mold section and is directed away from the first mold mounting surface. The platen apparatus further includes a plurality of compression members extending between the first and second walls for maintaining a wall spacing between the first and second walls, and an ejector assembly mounted between the first and second walls for ejecting molded articles from the first and second mold sections.

The present disclosure provides a mold of a resin body capable of reducing the cost of manufacturing a resin body including a resin base material and a foamed resin part provided on the resin base material. This mold is a mold of a resin body including resin base material molding die parts for molding a resin base material. The mold includes: a sliding part capable of sliding inside a foamed resin part molding cavity that communicates with a resin base material molding cavity of the resin base material molding die parts. The sliding part is swingably floated in a direction perpendicular to a sliding surface on which the sliding part slides. In the process of molding the resin base material, the sliding part blocks an opening part that communicates from the resin base material molding cavity to the foamed resin part molding cavity.

An active grille shutter system (AGS) that is assembled from modular components, thereby allowing the AGS to be any desired width or height when assembled. This allows for the creation of different sized AGS for different vehicle platforms, while assembling the AGS from a stock of components that is common to each AGS. The invention is also directed to a method of forming a base integrated end cap with moveable vane retainers and a link arm using a two shot molding process.

There is provided a manufacturing method of a liquid supply member capable of suppressing decrease in sealing property of a liquid supply path and deformation of the liquid supply path or the external shape. For that purpose, a manufacturing process of a liquid supply member prevents inflow of a molten resin into a concave portion of a portion other than a liquid supply flow path in a liquid supply member.

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.

A method of manufacturing a liquid supply unit includes a first molding step and a second molding step. In a first molding step, a resin is injected into different positions inside a mold assembly and a first member having a first contact portion, a second member having a second contact portion and an intermediate passage member having a passage structure to connect the first contact portion to the second contact portion are molded. In a second molding step, the mold assembly is disassembled, a die slide mold disposed inside the mold assembly is moved for positioning the members. Then, the mold assembly is clamped again and a resin is injected into the mold assembly. The first contact portion and the second contact portion are respectively held on the same surfaces inside the mold assembly during a period from the first molding step to completion of the second molding step.
