A third cavity part for forming a filter part of a mesh filter has opening forming pins of the same number as that of openings for forming regular-octagonal openings of the filter part. The opening forming pins are formed at regular intervals along an X-axis direction and a Y-axis direction, and a diameter of an inscribed circle of the regular octagon is equivalent to the dimension between the adjacent opening forming pins along the X-axis direction and along the Y-axis direction. The interval between a first line and a second line adjacent to the first line of the opening forming pins formed at regular intervals along a direction at 45 to the X-axis direction is equivalent to the interval between a third line and a fourth line adjacent to the third line of the opening forming pins formed at regular intervals along a direction at 135 to the X-axis direction.

A mold insert assembly includes a base section having a base side removably attachable to a base plate of a mold and a first interface surface having a notched portion thereon. A first section includes a first interface side with a first interconnecting tab sized to engage the notched portion of the base section when the first interface side abuts the first interface surface, the first section further including an adjoining side having an interconnecting notch. A second section includes a second interface side having a second interconnecting tab, where the second interconnecting tab is sized to engage the interconnecting notch of the first section when the second interface side abuts the adjoining side, and where the base section, the first section, and the second section when assembled form a contoured insert configured to create a contoured cavity in a part formed within the mold.

A suspension arm includes an arm portion and coupling portions, and the suspension arm is integrally made of a fiber reinforced plastics in entirety. The entire arm portion is made of a random fiber reinforced plastics. Each of the coupling portions is made of a continuous fiber reinforced plastics in which continuous fibers are oriented along a circumferential direction of an insertion hole over a region on a distal end side of the suspension arm, which continuously extends by at least a half circumference around a center axis of the insertion hole, the region including a position crossing a flat plane that is orthogonal to a straight line connecting center points of the insertion holes of elastic bushes and passes through the center point of the insertion hole.

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

To provide an injection mold capable of filling a necessary resin material for obtaining a desired molded article in a cavity space of a fine mesh structure, there is provided an injection mold according to an embodiment of the present invention composed of a core mold and a cavity mold, in which a cavity space is formed when the core and cavity molds are in a contact with each other, the cavity space surrounding a plurality of contact areas between the core and cavity molds. In the injection mold according to an embodiment of the present invention, at least one of the core and cavity molds has a through-hole which has an opening in a parting plane of the core and cavity molds and extends from the opening to an outside of the injection mold, the parting plane corresponding to the contact areas between the core and cavity molds.

The invention relates to a method for producing plastics containers from thermoplastics with inserts which, by exploiting the heat of plasticization, are connected during shaping of the plastics container by a material bond and/or interlocking connection to the container wall, wherein the method provides the use of at least one opening on the insert, which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall, wherein the method is distinguished in that the opening is monitored as a reference opening by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening with thermoplastic from the container wall is used as a measure of the quality of the connection.

A composite material has: a first layer in which a plurality of first sheets that are formed of a composite material including reinforced fibers and a resin are laminated; a second layer are laminated that each have a smaller thickness than any one of the first sheets and that are formed of a composite material including reinforced fibers and a resin; and a third layer that covers the surfaces of the second layer and the first layer and that is provided with a third layer which is formed of a composite material including reinforced fibers and a resin, wherein, when compared to the second sheet laminated on the side of the third layer, the other second sheets of the second layer occupy a larger area on the area of the surface of the first layer.

A lay-up method of composite aircraft parts with an opening. Composite tows having an orientation of 0?, 90? or +/?45? are laid up forming plies which form a composite laminate. Each tow having an orientation of 0? and being within the perimeter of the opening comprises: a first gap located at approximately ? of the length of the first semi-major axis from the center, the first gap being configured as a first elongated gap longitudinally perpendicular to the orientation of the tow, and a second gap located at approximately ? of the length of the second semi-major axis from the center, the second gap being configured as a second elongated gap longitudinally perpendicular to the orientation of the tow.

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

According to some aspects, a method is provided of removing debris from a liquid photopolymer in an additive fabrication device. According to some embodiments, a mesh of solid material may be formed in an additive fabrication device from a liquid photopolymer, and particles of debris present in the liquid photopolymer may adhere to the mesh. The debris may thereby be removed from the liquid photopolymer by removing the mesh from the additive fabrication device. The mesh may then be discarded.
