Introduced here are carrier assemblies designed to address the limitations of conventional carrier trays. A carrier assembly can comprise a primary injection-molded component having a deck area for receiving semiconductor components and a secondary injection-molded component that is secured to the deck area of the primary injection-molded component. For example, the secondary injection-molded component may be overmolded on the deck area of the primary injection-molded component. The secondary injection-molded component may have a tacky upper surface that facilitates securement of the semiconductor components to the primary injection-molded component.

Provided is a double injection molding system capable of continuously and automatically manufacturing four molded products for a vehicle at a time, the double injection molding system including: a first molding device which molds the openable plates of the molded products for a vehicle through injection of plastic; a second molding device which receives the openable plates and molds the sealing portions through injection of rubber around the openable plates to finish the molded products; and a transport device which takes out the openable plates formed by the molding device and transports the openable plates, to the second molding device, so that the double injection molding process of the openable plates and the sealing portions is automated to secure product reliability and to improve productivity.

In order to prevent shaft portion from being broken in ejection of base portion from mold, method for manufacturing interdental cleaning tool includes: base portion forming step of forming base portion by filling first space of primary mold (50) with synthetic resin, which includes first and second mold members (50A, 50B); and cleaning portion forming step of forming cleaning portion around shaft portion by filling second space of secondary mold with elastomer. Base portion forming step uses first and second mold members (50A, 50B). First and second molds include: first and second contact surfaces (51A, 51B); pair of first and second spaced-apart portions (54A, 54B); and first and second connection portions (52A, 52B), angle (θ) between each of first and second spaced-apart portions (54A, 54B) and separation plane being acute.

A method of manufacturing a window surround for a vehicle, a window surround for a vehicle, and a device for manufacturing a window surround. The window surround includes a first component to serve as a circumferential support frame to hold a window glass panel, a second component, composed of a material of less hardness than the material of the first component, onto the first component, to serve as a circumferential sealing element, and a third component that is composed of a high gloss material. The method includes injection molding the first component onto a window glass panel, then injection molding the second component onto the first component, and then injection molding the third component onto the first component.

A shower head is supplied with an annular airflow which surrounds a column of water travelling through a chamber to produce a suspension of water droplets in air, the diameter and length of the chamber and the diameter of the water column are selected in combination with the fluid flow parameters to operate the shower within a defined parameter space corresponding to the non-axisymmetric Rayleigh breakup regime, where the water column remains intact and spaced apart from the chamber wall for the entire length Lc of the chamber, where the airflow perturbs the water column within the chamber causing it to disintegrate into droplets downstream of the chamber outlet, and where multiple chambers are moulded on non-parallel axes with elastomeric linings facilitating withdrawal of the mould tool.

A method for forming a light engine assembly includes the steps of injecting a light trough material into a mold, thereby forming a light trough including a trough body having an edge, and injecting a seal material into the mold, thereby forming a seal configured to bond with the edge of the trough body. The method further includes cooling one of the light trough material and the seal material to adhere the light trough material to the seal material, thereby forming a unitary light trough part, ejecting the light trough part, and coupling a lighting unit with the light trough part.

To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part.
