An aspect of mold for producing an end plate of a planetary gear carrier includes a mold body and a cylindrical protrusion extending from a front surface of the mold body. The cylindrical protrusion defines a cylindrical interior space fluidly linked to an interior space of the mold body. The mold also includes an injection gate disposed on a rear surface of the mold body and aligned with a longitudinal axis of the cylindrical protrusion, wherein the injection gate is configured to allow an injection nozzle to inject a molding material into the interior space from an exterior of the mold body. In some aspects, the molding material includes additives that can improve the properties of the resulting molded part. Other aspects of the present disclosure include molded carriers for planetary gear devices, and related processes or methods for making similar molded parts.

An identification device configured to acquire a collation fixed image of a part of a region where a fixed pattern is formed, and a collation amorphous image of a part of a region where an amorphous pattern formed when the fixed pattern is formed on a region different from the region where the fixed pattern is formed, of a collation molded article; refer to a storage unit that stores, as a registered image in advance for a mold, a fixed image and an amorphous image pair of a part of a region where a fixed and an amorphous pattern are formed, of each of plural molded articles formed using the mold; specify a mold that forms the collation molded article using the registered fixed and collation fixed images, and identify whether the collation amorphous image matches the registered amorphous image of any of the registered images corresponding to the mold.

The present disclosure provides a marbled molded product obtained by injection-molding, in a mold cavity, a mixture including: a thermoplastic resin including one selected from the group of polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof; and fine pigment particles, where a pattern forming a texture is formed on the surface of the injection-molded product. The present disclosure also provides a system for evaluating a marble color effect of a marbled molded product, the system including: a light source unit, an image-capturing unit, an image processing unit and an evaluation factor determination unit.

A resin molding has a first surface and a second surface, wherein the second surface includes a rib, and wherein the first surface includes a glossy portion and a non-glossy portion.

Non-time dependent measured variables are used to effectively determine an optimal ejection time of a part from a mold cavity. A system and/or approach may first measure at least one non-time dependent variable during an injection molding cycle. The part is ready to be ejected from the mold upon the measured variable reaching a threshold value indicative of, for example, a part temperature dropping below an activation temperature.
