Provided herein are polyamide compositions having desirable flow properties, for example low viscosity, which is useful for molding small components. The polyamide compositions comprise a polyamide comprising 1,10-decanediamine terephthalamide (10T) repeating units; a copolyamide comprising repeating units derived from terephthalic acid and from a diamine containing 6 or fewer carbon atoms; a reinforcing agent; and optionally, one or more of a flame retardant, a flame retardant synergist, and a lubricant.

A method of manufacturing a support member, which includes a tubular-shaped tubular part and a coupling part coupling one portion and another portion of an inner circumferential surface of the tubular part to support a ventilation membrane, includes filling a fixed mold and a movable mold with a thermoplastic material or a thermosetting material, wherein the thermoplastic material or the thermosetting material is injected from a gate in the coupling part to be charged from the coupling part toward the cylindrical part.

To prevent a core from being damaged. A method for manufacturing a reactor includes a step of assembling a core that is configured of a core center part and a pair of core leg parts extending outwardly from the core center part to a coil in such a way that the core center part is inserted into a hollow part of the coil and the coil is sandwiched between the core center part and the pair of the core leg parts; and a step of performing resin molding by disposing the coil and the core that are assembled inside a mold and pouring resin into the mold from a gate provided on the mold to the side which is closer to the coil than the core legs parts are while having an outer surface of each of the core leg parts supported by a support part provided on the mold.

Golf ball methods and molds for quickly and efficiently eliminating air/gas from within a mold while better centering a subassembly in the mold during golf ball manufacture and the improved golf balls resulting therefrom.

A mold apparatus for forming a molded part includes a mold body, a mold cavity formed in said mold body, a plurality of valve gates associated with said mold body, and a controller in communication with said plurality of valve gates. The controller is programmed to time opening of each valve gate based on a selected flow rate required to eliminate weld lines in the product.

A compression collar is manufactured for reinforcing an interference fit between an end of a pipe and a fitting. A precursor form is injection molded using a cold-expansion material. The precursor form has a tubular body with an initially closed axial end and a bore initially blind formed in the other axial end. Material is removed from the initially closed axial end to form an opening that connects to the bore thereby forming the compression collar. The opening has an inner periphery with a profile in axial cross section that is different than any profile in axial cross section of an inner periphery of the bore. The collar formed lacks knitlines and includes tabs which help to position the collar on a pipe.

A heating assembly configured to receive a power cable for restoring an insulation system of the power cable, the heating assembly including: a central pressurisation and heating structure, and a first and second lateral structure provided at a respective axial end of the central pressurisation and heating structure, the first and second lateral structure each having at least a 20 cm long axially extending section primarily made of a material at most having a conductivity of the order of 1000 S/m at 20° C.

A pressurisation and heating device for restoring an insulation system of a power cable, the pressurisation and heating device including: a first part including a first channel configured to receive a portion of the power cable, a second part including a second channel configured to receive a portion of the power cable, wherein the pressurisation and heating device is configured to be set in a closed state in which the first channel faces the second channel thereby forming a heating chamber extending from a first end to a second end, opposite the first end, of the pressurisation and heating device, wherein the pressurisation and heating device is configured to be pressurised to obtain a pressure higher than atmospheric pressure inside the heating chamber when the power cable is arranged sealed in the heating chamber, wherein the pressurisation and heating device has an at least 20 cm long axially extending section which is primarily made of material at most having a conductivity of the order of moo S/m at 20° C.

The present invention relates to an FPC connector housing, more particular to a DDRS connector housing. The invention also relates to a method for producing the connector housing as well as to a cavity mold suitable for the production of the connector housing. The cavity mold comprises a double gating system with centrally positioned injection gates. The connector housing can be used in a connector for mounting on a flexible printed circuit (FPC) assembled in various kinds of electrical and/or electronic devices.
