An injection molding apparatus for inserting atypical stiffener including an upper mold provided with an upper core and an under mold provided with an under core for manufacturing an injection molding product by receiving synthetic resin melt and curing in a state in which an atypical stiffener whose size is not constant is inserted, may include elastic clampers supported by the under mold, embedded in the under core, interlocked with the size of the atypical stiffener, and elastically pressurizing both sides to hold the atypical stiffener to be inserted into a correct position between the upper core and the under core by the atypical stiffener when the synthetic resin melt is introduced.

The invention relates to an ultrasonic booster (1) for a sonotrode (30) for processing workpieces (W) with ultrasonic vibrations, having a booster body (10). Longitudinal vibrations (SL) are introduced into the booster body (10) on a sound introduction side (11) having a first end side (12). A conversion structure (15), by means of which transverse vibrations (ST) having a vibration component in a plane (E) perpendicular to the longitudinal axis (L) are generated from the longitudinal vibrations (SL), is located between the sound introduction side (11) and a coupling side (13) opposite the sound introduction side.

A decorative molded component includes: a substrate having a shell extending along a mating surface and a through hole adjacent to the shell and defined along the mating surface; and a molded body coated to the mating surface, the molded body covering the through hole to be continuous from a skin bonded to the shell. The decorative molded component improves appearance while keeping the functions of the two members.

An energy-absorbing assembly includes a first component and a second component. The first component includes a first polymer and a first plurality of reinforcing fibers. The first component includes a first peripheral wall defining a first interior compartment. A first interior portion of the first peripheral wall includes a first corrugated surface. A second component includes a second polymer and a second plurality of reinforcing fibers. The second component includes a second peripheral wall. A second interior portion of the second peripheral wall includes a second corrugated surface. The first corrugated surface is complementary to the second corrugated surface. The first corrugated surface is joined to the second corrugated surface.

An additively manufactured structure and methods for making and using same. In a method for making the structure, a first layer structure can be formed. A second layer structure can be formed on the first layer structure and a support structure. The support structure can be removed from the second layer structure. The second layer structure can include an overhang structure that does not deform or break after the support structure is removed. The support structure can provide support to the second layer structure during printing. Strong bridging capability of the second layer structure is not required. The support structure can be quick and easy to make. The support structure can be reusable and does not add weight to the printed structure. The support structure can be easily removed after completing of printing. Installation of the support structure can be fast without significantly interfering with printing process.

The present invention relates to an injection molding method using a fiber-reinforced composite material as an insert, and an injection molded product, and provides an injection molding method comprising: a step of preparing a fiber-reinforced composite material having a high-strength fiber, which is an insert material, impregnated in a resin; an insert formation step of manufacturing an insert by molding the fiber-reinforced composite material into a preliminary shape; and an injection molding step of manufacturing an injection product by arranging the insert in an injection mold and injecting a resin.

A rail extension, comprising: a base extending from an end of the rail extension, wherein the base includes vehicle rail attachments configured to attach to a vehicle rail; a front member configured for attachment to a bumper beam; a body extending from the base to the front member; wherein the body comprises reinforcing members; wherein the body comprises a first polymeric material; wherein the reinforcing members comprise a second polymeric material.

Disclosed is a resin composition for an exterior material of a vehicle. The resin composition may include an amount of about 40 to 90 parts by weight of polypropylene resin having a melt index of about 70 to 110 g/10 min; an amount of about 10 to 40 parts by weight of an olefin block copolymer including an ethylene-based repeating unit and a -olefin-based repeating unit having 4 to 30 carbon atoms; an amount of about 10 to 20 parts by weight of needle-shaped inorganic filler having an aspect ratio of about 5 to 10; and an 0.01 to 5 parts by weight of laser-transmitting black colorant, wherein all the parts by weights based on 100 parts by weight of the resin composition. In particular, an average transmittance may range from about 0.01 to about 1% or less in a wavelength of about 380 to 700 nm, and an average transmittance may range from about 15% or greater and less than about 100% in a wavelength of about 800 to 1200 nm.

A block of construction material is fabricated by harvesting a plurality of tread strips from a plurality of tires by, for each tire, removing a tread texture of a tread cap from each tire using a tread removal device while leaving a remaining portion of the tread cap intact with one or more sidewalls and shoulders of each tire, removing the side walls and the entire shoulders from each tire by cutting through the remaining portion of each tread cap, and slicing the remaining portion of each tread cap to produce tread strips. Each strip is preheated, and while maintaining the temperature, stacked onto the gummed previous strips, until a block of desirable size is yielded. Use of fasteners, plates and membranes to maintain the stacked tread strips into a block arrangement is eliminated.
