An injection molding device for fabricating a part, the device including an injection mold, the mold being formed of a support and a countermold that are distinct and that define between them a mold cavity presenting a first shape; and at least one injection device for injecting a fluid material into the mold cavity; the device including deformation elements configured to modify the shape of the mold cavity into a second shape distinct from the first shape.

A mold for resin injection molding 1 having a shaping region formed by a low-density shaped portion 22 and a high-density shaped portion 21 in which each ventilation channel 32 for gas existing between an external region and a molding portion region forms a hollow state surrounded by a peripheral wall having any one or both of the high-density shaped portion 21 and the low-density shaped portion 22, and the secondary vent 33 connecting communicatively with a region molding portion is formed only by a low-density shaped portion 22 with thickness thinner than that of the shaping region.

An insert member (100) heated by a heating device (13) is conveyed, by means of a conveyance device (12), into a mold (51). Next, shaping is performed on the insert member (100) inside the mold (51), with the mold (51) being open by a minute distance. A molding material (91) is injected into the mold (51) and pressed while closing the mold (51) which has been open by the minute distance to thereby mold a molded article (80) including the insert member (100).

Methods to increase structural performance, strength, and durability of textile-reinforced composite materials are provided. The textile reinforcement may be knitted, for example, in a flat bed weft knitting machine. The method may include pre-stressing a textile reinforcement preform by applying tension. A polymeric precursor may be introduced to the pre-stressed textile reinforcement preform. The polymeric precursor may then be cured or consolidated, followed by releasing of the applied tension to form the composite article comprising polymer and the pre-stressed textile reinforcement. In other aspects, a composite article is provided that has a pre-stressed textile reinforcement structure and a cured polymer. The textile reinforcement may be a knitted, lightweight, seamless, unitary structure. The knitted reinforcement structure may have distinct first and second knitted regions with different levels of pre-stress, thus providing enhanced control over strength, rigidity, and flexibility of the composite article.

An object is to provide an injection stretch blow molding machine and a method for molding a polyethylene container capable of molding a favorable hollow container even if its preform is released from an injection mold early. The injection stretch blow molding machine and the method for molding a polyethylene container molds a preform by injecting and filling a molten polyethylene resin into an injection mold, which includes a cavity mold and a core mold both cooled to a temperature range of 5° C. to 25° C., transfers the molded preform to a blow molding mold, and molds a hollow container by blowing the preform within a time range of ±2 sec from a point in time when a temperature of the preform reaches a first minimum point after a point in time when the injection mold completes being opened.

Injection molding machine comprising at least one first and one second injection unit having a chamber for injecting a plasticized molding material and a piston for advancing a predetermined amount of plasticized molding material along a first axis from the chamber into a cavity of a mold, the machine including a form tool comprised of at least a first tool portion and a second tool portion, a tool cavity being at least partially disposed in the first tool portion.

The present disclosure relates to a surface-modifiable injection-molded body comprising a thermoplastic polymer matrix and second polymer material at least in parts, in which the polymer matrix and the second polymer material have different weight average molecular weights and polarities, and the second polymer material is an adhesive. The present disclosure also relates to a method for its production.

Embodiments of the present disclosure provide a method of forming a cover of a fuel intake system of a vehicle. The method may include providing a mold that defines a cover-forming cavity having a main body portion and a grounding strap portion connected to the main body portion, inputting a forming material into the cover-forming cavity to a specified level, allowing the forming material within the cover-forming cavity to cool and harden, separating the mold to expose the cover having an integrally molded and formed grounding strap, and removing the formed cover having the integrally molded and formed grounding strap from the separated mold.

A moving apparatus is disclosed that may be for moving a tool of an injection molding machine. It may comprise a beam having at least a part that extends generally longitudinally in a first direction. The beam may be configured such that the tool can be moved relative to the beam in said first direction. The apparatus may also comprise an actuator for moving the at least a part of the beam in a second direction. Also disclosed is a method of moving a tool. The method may comprise: (a) moving a tool along a beam that generally extends in a first direction; and (b) moving at least a part of the beam in a second direction. The first directions may be orthogonal to second directions.

A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is there removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.
