11452799 · 2022-09-27 · ·

An elastomer molded body for a medical device includes an elastomer portion and a filler. The elastomer portion contains a crosslinked fluorine-based elastomer. The filler is formed from a plurality of particles each of which has aspect ratio of 5 or more and specific surface area of 3 m.sup.2/g or more and 10 m.sup.2/g or less. The aspect ratio is defined as a ratio of a dimension in a long axis direction thereof to a dimension in a short axis direction thereof. The filler has an uneven distribution in a surface layer part of the elastomer portion and is oriented in a direction along a surface of the elastomer molded body.

Method of injection molding
09718226 · 2017-08-01 · ·

A method for an injection molded product having a molten resin containing an aluminum pigment. The injection mold includes resin reservoirs connected to both sides of a cavity, positioned where the molten resin meets as it partly flows therein. The cavity has a design surface of an injection-molded product and both side surfaces continuing from the surface forming the design surface. One of the resin reservoirs is connected to one of the side surfaces and the other resin reservoir is connected to the other side surface, across the position where the molten resin meets. When the molten resin partly flows into the resin reservoirs, flow of the molten resin, which is substantially in parallel from the surface forming the design surface to the resin reservoirs, is generated and aluminum pigment makes an orientation angle of 120° to 140° on the design surface at the position where the molten resin meets.

INJECTION MOLDING METHOD WITH METALLIC PIGMENT USING MAGNETIC FIELD
20200316833 · 2020-10-08 · ·

A method for molding a part includes forming a mold having a part cavity and an associated electromagnet, placing resin in the part cavity, the resin including a ferromagnetic pigment, energizing the electromagnet and moving the ferromagnetic pigment towards an A-surface area of the part, and curing the resin with the ferromagnetic pigment concentrated at the A-surface area of the part. The A-surface of the part is free of flow marks and dark spots. Also, the ferromagnetic pigment is introduced into the resin before the resin is placed in the part cavity, or in the alternative, the ferromagnetic pigment is introduced into the resin after the resin is placed in the part cavity.

A method of forming a single piece, shaped, down feather thermally insulating article having different thermal insulating sections is described. A mold is formed with a cavity defining a non-uniformed prescribed shape and having sections of different shapes and depths. Down feather clusters or a mixture thereof is mixed with a binding material and is injected into the mold which is then heated with a suitable heat source to cause the binding material to soften and fuse the mixture together. After cooling the mold, there is formed a single piece, shaped, down feather article which is comprised of sections having different thermal insulating values for use in a product where parts of the product provide different thermal insulating properties.
