Method and tools for manufacturing core foam sections for a propeller is disclosed. In an embodiment, a method comprises wrapping a first adhesive film around pre-drilled rods; placing the rods into a first mold using placement features; injecting a high density material into the first mold and around the rods; curing the high density material to form a first cured component; removing the first cured component from the first mold; placing a second film adhesive onto the first cured component; placing the first cured component into a second mold; closing the second mold; injecting a low density material into the second mold; curing the second density material to form a second cured component, wherein the first and second cured components are bonded together.

A method of making a cleaning-roll body having a core and a jacket on the core. The method has the steps of forming the core of a first polymer by injection molding in a first injection mold, removing the injection molded from the first mold, inserting the formed core into a second mold and overmolding the jacket on the formed core.

The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.

The invention relates to a technical field of car roller shutter door production, in particular to a method for manufacturing a car roller shutter door. A single film piece is firstly vacuum formed into a desired shape, and then rubber is injected into the film piece after vacuum forming, so that the rubber and the film piece are integrally formed to form a single roller shutter strip, and then a required number of single roller shutter strips are placed and laminated on a flexible substrate in an integrated and orderly manner to form a car roller shutter door. Each of roller shutter strips is independent of each other and does not interfere or affect each other, which improves flexibility of the car roller shutter door. Compared with long strips of whole film sheet on the car roller shutter door in the prior art, each of film pieces of the present invention is independent of each other and does not have defect of easy fracture of the whole film sheet, which makes service life long. In addition, production of the single film piece is less expensive and more efficient, and pattern design is flexible. When one of the roller shutter strips is damaged, only the damaged roller shutter strip needs to be replaced in a targeted manner, avoiding the waste of resources and reducing maintenance costs.

A platen apparatus for supporting a mold portion in an injection molding machine includes a platen body and a mold mounting face adjacent a front of the platen body for supporting a mold half. The mold mounting face includes a rotary central surface that is rotatable about an axis relative to the platen body and a fixed peripheral surface that is fixed relative to the platen body. The peripheral surface is disposed about a periphery of the central surface. The central surface and the peripheral surface are alignable in a common vertical plane.

A film material insert molding method, includes an intermediate part forming step of forming a first intermediate part having an edge extending radially outward, the edge being disposed at and near an outer peripheral end of a final shape of a film material, a transparent resin layer forming step of forming a second intermediate part including a transparent resin layer, by injection molding, on a front surface of the first intermediate part, with the edge of the first intermediate part being fixed, and a substrate resin layer forming step of forming an insert-molded article including a substrate resin layer, by injection molding, on a back surface of the second intermediate part, the substrate resin layer covering a surface of a radially outer end of the edge.

An integrated multi-color animal chew toy and preparation process thereof, including selecting N types of rubbers used to form a product, wherein the rubbers have different colors and different hardness; selecting one type of rubber from the rubbers used to form the product, putting the rubber selected into a first mold, and performing mold forming to form a first molded product; putting part of the first molded product into a second mold, closing the second mold, and then injecting a second rubber selected from the rubbers used to form the product for mold forming to form a second molded product; putting part of the second molded product into a Nth mold, closing the Nth mold, and then injecting a Nth rubber selected from the rubbers used to form the product for mold forming, and then cooling to obtain the product completely.

A method for manufacturing a resin container includes: injection-molding a first layer of a bottomed cylindrical preform from a first resin material as a first injection-molding; accommodating the first layer manufactured in the first injection-molding in a temperature adjustment mold, adjusting a temperature of the first layer, and forming an opening portion in a bottom portion of the first layer; injecting a second resin material from the opening portion to an inner peripheral side of the first layer to laminate a second layer on the inner peripheral side of the first layer, as a second injection-molding; and blow-molding a multilayer preform obtained in the second injection-molding-step in a state where the multilayer preform includes residual heat from the injection molding to manufacture the resin container.

Disclosed is a molding having a translucent surface layer and to a method for producing a molding that has a translucent surface layer.

A vehicle-window glass assembly includes a vehicle-window glass and its injection-molded encapsulation; and an over-molded bolt including a base, a thread rod and an injection-molded part. One end of the thread rod is fixedly connected to the base, and the injection-molded part covers at least a part of the base. The injection-molded encapsulation covers at least a part of the injection-molded part such that the over-molded bolt and the vehicle-window glass are fixed to each other, and a material of the injection-molded part has a tensile strength greater than that of a material of the injection-molded encapsulation. This vehicle-window glass assembly can b e adapted to various vehicle models with a large gap between a surface of a vehicle-window glass and a vehicle-door sheet metal on which the vehicle-window glass requires to be mounted.
