A magnesium alloy/resin composite structure (106) including a magnesium alloy member (103) and a resin member (105) integrated to the magnesium alloy member (103) and made of a thermoplastic resin composition, in which the magnesium alloy member (103) surface to which the resin member (105) is not integrated is coated with a layer including a manganese atom, an oxygen atom, and a sulfur atom.

The invention relates to an apparatus and a method for the production of a particle foam part, wherein a mould cavity (5) is filled with foam particles, the foam particles are welded into a particle foam part and the particle foam part is cooled down in the mould. The foam particles are heated by means of a ceramic body (17) with integrated resistance heating and by the application of electromagnetic waves.

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. The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.

The present invention relates to a thermoplastic resin composition, a method of preparing the same and a molded article including the same. More particularly, the thermoplastic resin composition includes a polycarbonate resin having a limited melt flow index, a polyorganosiloxane-polycarbonate resin, a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound copolymer, a polyester resin and an epoxy group-containing copolymer in predetermined weight ratios.

A caulking pin (15) is inserted into a mounting hole (21) provided in a metal case body (3), and the end portion of the caulking pin (15) is thermally caulked with a welding tip (24) to form a mold forming portion (17). A surplus absorption recess (31) is formed by enlarging the opening end of the mounting hole (21), and surplus resin is absorbed. The surplus absorption recess (31) is positioned inside a region of the mold forming portion (17). Therefore, the amount of molten surplus resin that protrudes outward from the welding tip (24) in the thermal caulking process is reduced.

Polyester polymer compositions are described containing a blend of coloring agents and optionally reinforcing fibers. The polyester polymer, for instance, can be polybutylene terephthalate. The polymer composition is particularly formulated in order to be substantially transparent at specific wavelengths of light. Consequently, the polyester polymer composition is well suited for use in laser transmission welding in which a laser beam passes through the polymer composition and forms a weld on an adjoining surface.

A resin composition comprises, based on 100% by weight of the resin composition: 45-70 wt % of a main resin, 20-45 wt % of a chopped glass fiber, 1-3 wt % of a toughening resin, 0.2-0.5 wt % of an unmodified glycidyl methacrylate, and 0-10 wt % of an auxiliaries. The main resin is selected from at least one of PBT resin and PPS resin. The chopped glass fiber has a dielectric constant of 4.0 to 4.4 at 1 MHz.

A thermoplastic polyester resin composition is obtained by blending, with respect to (A) 100 parts by weight of a thermoplastic polyester resin, (B) 0.1-50 parts by weight of at least one phosphinate selected from phosphinates and diphosphinates, (C) 0.1-10 parts by weight of a phosphazene compound, (D) 0.1-50 parts by weight of a nitrogen-based flame retardant, (E) 0.1-10 parts by weight of a polyfunctional epoxy compound, and (F) 0.1-20 parts by weight of an olefin resin. The ratio of the parts by weight of component (B) and the parts by weight of component (C) is 2.0-8.0.
