The invention is directed to an overmolded two-component friction element in a plastic pallet and to a method for forming the pallet. The friction element includes a rigid outer carrier member and an elastomeric material that is exposed at one or more ends. The friction element is first formed in an injection mold, and then is placed in a pallet mold. Resin is injected into the pallet mold around the sides of the friction element leaving the exposed elastomeric material form part of the pallet surface.

A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

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.

A window including a layer of optically clear structural polymer core and two layers of optically clear silicone applied to first and second sides of the core. A method is disclosed for manufacturing a window that comprises injection molding a layer of optically clear structural polymer and solidifying the structural polymer core. Optically clear silicone is then injected onto the entire surface of both of the first and second sides of the optically clear structural polymer core.

Provided is a method for manufacturing a rotary power transmission member including a ring-shaped main body part fixed to a rotating shaft, and a ring-shaped gear part formed on an outer circumference part of the main body part to transmit rotational force of the rotating shaft to other members. The method includes gear part molding for injecting a high melting point resin into a first mold to mold the gear part, and main body part molding for injecting a low melting point resin to mold the main body part while the gear part being inserted into a second mold. The first mold includes a runner defined on an inner circumference side of a ring-shaped cavity for molding the gear part, and a gate which communicates the runner with the cavity to supply a resin into the cavity.

A dual-molded silicone-polyamide composite article including a first molded piece that comprises a blend of polyamide and an ethylene-vinyl alcohol copolymer and a second molded piece that comprises a thermoset, hydrosilylation-cure silicone polymer. A portion of a surface of the second molded piece is autogenously bonded to a portion of a surface of the first molded piece.

Disclosed herein is a lens comprising a central portion that comprises a first polymer; wherein the central portion is operative to transmit electromagnetic radiation through it; and a peripheral portion that comprises a second polymer; where the peripheral portion accommodates a dimensional change in the central portion by absorbing energy and being transformed from a lower energy state to a higher energy state. Disclosed herein too is a method of manufacturing a lens comprising injecting into a mold a molten polymer to produce the lens; where the lens comprises a central portion; and a peripheral portion; where the peripheral portion accommodates a dimensional change in the central portion by absorbing energy and being transformed from a lower energy state to a higher energy state.

A method of making a saddle having a shell and a padding involves arranging the shell in thermoplastic polymer inside a mould for injection moulding having a die and a punch, the shell having a support surface, which in use faces the padding, and a supporting surface coupled to an inner wall of the punch or of the die, the support surface forming a wall of the moulding cavity; closing the mould; and making the padding by injection moulding a thermoplastic polymer over the shell, between the support surface and the mould.

In the primary molding step, the insert core having axially-projecting convex portions aligned apart from one another in the circumferential direction is located in a primary molding die, and the injection molding is performed. In the secondary molding step, the annular internal resin member and the insert core which have undergone the primary molding step are located in a secondary molding die, and the injection molding is performed. Gates for injecting molten resin in a cavity of the secondary molding die are located in the secondary molding die so that welds that are joining points of the molten resin in the secondary molding step are positioned in the radially outside of rib portions.

A method of forming a molded polymer part having a screw boss includes positioning a screw boss insert on a pin of a mold tool. The screw boss insert may contact guide surfaces of the mold tool. During molding, polymer material flows along the screw boss insert while the screw boss insert is positioned on the pin. The polymer material may bond to the screw boss insert. The screw boss insert may include one or more geometric features that prevent rotation and/or axial movement of the screw boss insert relative to the surrounding polymer material.
