A mold clamp control method for an injection molding machine having a toggle-type mold clamping mechanism. The mold clamp control method includes: a low-pressure mold clamping step that performs position hold control by which a crosshead is held in a set holding position in a state where a toggle link has been bent, when injection-filling is started; and a compression-press step that performs speed and position control by which the crosshead is advanced toward a set advancement position from the set holding position in a state where a first output upper limit value has been provided to a driving section. Advancement of the crosshead is continued in at least part of the compression-press step in a state where a generated output of the driving section is maintained at the first output upper limit value.

A method of producing a fiber-reinforced resin-molded member includes: preparing a mold including an upper mold and a lower mold forming a cavity, a cavity surface of either the upper mold or the lower mold being provided with a projecting portion; disposing a fiber-reinforcing material in the cavity, closing the molds to generate a state in which the projecting portion presses a part of the fiber-reinforcing material, and filling the cavity with a melted resin to impregnate the fiber-reinforcing material with the melted resin and cure the melted resin; and opening the molds to obtain a fiber-reinforced resin-molded member having an exposed portion and an embedded portion. The exposed portion includes at least a portion pressed by the projecting portion while the molds are closed.

An in-mold vibratile injection compression molding method and molding apparatus thereof are described. While performing a filling stage, a first piezoelectric actuator and a second piezoelectric actuator are use to vibrate the molding material along at least two directions for precisely filling the molding material into the micro-structure by adjusting the filling flow velocity of the molding material associated with the proper molding material temperature and by maintaining a molding material temperature of a skin solidified layer in the cavity between a glass transition temperature and a melting temperature in order to avoid the form error, to increase the groove filling rate and to improve the residual stress.

The at least one contact is electrically connected to the at least one wire such that an electric current is conductible from the at least one wire into the at least one contact. A temperature-sensitive measuring resistor is contained in the housing and is electrically connected to the at least one wire such that at least a portion of the electrical current that is conductible into the at least one contact flows through the measuring resistor. A metallic element is disposed on the housing and thermally connected to the measuring resistor.

A loudspeaker diaphragm includes resin and hollow glass member particles contained in the resin. Further, a loudspeaker includes the above-described loudspeaker diaphragm, a magnetic circuit, a frame connected to the magnetic circuit, and a voice coil body having one end connected to the loudspeaker diaphragm and the other end disposed inside a magnetic gap in the magnetic circuit.

The present invention provides a method for manufacturing a molded foam product which can reduce blisters on the surface and foaming failure in injection molding of a molten resin containing a fluid in a supercritical state even in the case of manufacturing a molded product designed to have a small thickness, thereby giving a molded foam product having excellent heat insulation. The method of the present invention is a method for manufacturing a molded foam product through injection molding of a molten resin containing a fluid in a supercritical state, the method including a step of injecting the molten resin into a cavity formed in a mold and moving a portion of the mold to increase the volume of the cavity before the molten resin injected into the cavity completely solidifies, the cavity being communicated only with a single resin injection port, the mold having a dimple which has a substantially hemispherical shape and is situated to face the resin injection port, the mold having a minimum gap size of 0.2 mm or greater in the cavity during injection of the molten resin.

Methods for producing an encoder are disclosed. In one example, a method may include introducing an insert part into a mold, wherein the insert part is a support part, a metal foil, or a metal-coated foil. A first component may be injected into the mold, wherein the first component is an adhesion promoter. The first component is then cooled, wherein the first component joins with the insert part. A second component is injected into the mold, wherein the second component includes a material which comprises polyamide 6, polyamide 12, or polyphenylene sulfide and at least one magnetic filler. The second component is then cooled, wherein the second component joins with the first component and forms the encoder.

A method of producing a molded product includes preparing a mold for insert molding in which a cavity corresponding to a molded product including a trunk portion and an arm portion is defined, disposing an insert member including a bent portion and a first extending portion extending from the bent portion in a state in which one side of the insert member is supported in the cavity such that the first extending portion is downstream of the bent portion in a flow direction of molten resin, wherein the mold includes, on a wall surface defining a space corresponding to the arm portion in the cavity, a first projecting portion that supports a part of a surface of the first extending portion positioned on a major angle side of the bent portion, and injecting molten resin into the cavity.

Apparatus and associated methods relate to an enhanced auxetic composite material (EACM) of a base thermoplastic elastomer (TPE) and/or a thermoset material combined with an auxetic material, the composite formed with a molding process, where the base material is injected or dripped into or injected, dripped or formed around the auxetic material, the composite material providing higher impact performance than the individual materials. In an illustrative example, combining various energy absorbing materials with auxetic materials may further enhance impact performance. In some examples, TPE material injected into auxetic structures may fill internal voids. In some examples, the auxetic material may be suspended within the TPE material and be encapsulated around the auxetic material form. Auxetic materials may take various forms, for example, sheets, 3-D structures, and particles, each providing unique benefits. Various embodiments included within various personal protection articles may advantageously provide long life and enhance impact resistance.
