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.

A hollow article such as an active bolster for an automobile is formed of an injection molded panel having a ridge and furrow adjacent a panel perimeter and an injection molded sheet having a bonding section at a sheet outer periphery, wherein the bonding section is within the furrow. An injection molded bond is formed between the bonding section and furrow, wherein a compression area where the sheet overlies a region of the panel adjacent the furrow is configured to constrain the bond to the furrow. An associated process and system facilitates mold alignment, part alignment, material strength, design adaptability, efficient processing, reduced labor, increased production rates, reduced energy consumption per part, aesthetically pleasing surfaces, and reduces or eliminates the need for a separate welding operation.

An assembly of joined injection molded parts and a method for joining injection molded parts is disclosed herein. The assembly includes, but is not limited to, a first injection molded part having a first bonding area. The first bonding area has a plurality of first fingers extending from a surface of the first bonding area. The assembly further includes a second injection molded part having a second bonding area. The second bonding area corresponds in shape to the first bonding area and has a plurality of second fingers that extend from a surface of the second bonding area. The assembly includes an adhesive tape arranged between the plurality of first fingers and the plurality of second fingers. The adhesive tape is configured to bond the first injection molded part to the second injection molded part.

A failure module includes a support element. A reinforcing element is disposed on the support element. The support element is chemically compatible with the reinforcing element. A homogeneous chemical bond is formed between the support element and the reinforcing element.

A two-color molded article includes a first resin part, and a second resin part in contact with the first resin part so as to at least partially overlap the first resin part. The second resin part includes a single layer region provided between a first region and a second region and provided in a penetrating portion formed between a first portion and a second portion. The single layer region has a joint portion in contact with a bent portion. The joint portion is formed in a convex shape with respect to the bent portion.

A steering wheel is provided with a heater element on the rim. The heater element is mounted at least on a part of a core of the rim, and a cladding layer formed from synthetic resin foam covers an outer circumference of the heater element. The heater element includes a cord-shaped heater and a base material. The base material includes an insulation sheet that is formed from synthetic resin foam and disposed to face towards the core and a permeable sheet that is formed from non-metal which allows permeation of the cladding layer. The insulation sheet and permeable sheet are bonded together and sandwich and support the cord-shaped heater there between.

An instrument panel (10) includes a base material portion (20) made of a base material M1 and a different material portion (30) made of a different material M2 having a different thermal shrinkage from that of the base material M1, and in the instrument panel (10), the base material portion (20) and the different material portion (30) are connected in a state such that at least a part of the two materials do not overlap.

A polyurethane-based display, in particular for a vehicle, includes a decorative element with at least one cutout. At least one printed sheet is disposed in the at least one cutout such that the printed part of the printed sheet is visible. The printed sheet is coated with a first polyurethane layer.

A cosmetic device and related methods of manufacturing and using a cosmetic device. The device may comprise a porous part formed using a soluble filler and a non-porous part molded to the porous part.
