Various embodiments disclosed relate to antioxidant-stabilized materials including ultra high molecular weight polyethylene (UHMWPE), methods of making the same, and medical implants including the same. In various embodiments, the present invention provides a method of adding antioxidant to UHMWPE. The method includes obtaining or providing a porous solid material including UHMWPE. The method includes coating the porous solid material with a liquid composition including at least one antioxidant such that at least some of the liquid composition enters void space of the porous solid material, to provide an antioxidant-infused solid material. The method also includes melt-consolidating the antioxidant-infused solid material, to provide a melt-consolidated material.

Method for rounding edges of polymer motor vehicle components
10226901 · 2019-03-12 · ·

A method is provided for producing a polymeric vehicle component, particularly an outer component in the form of a bumper, spoiler, sill, mud guard or the like. A polymeric shell part is first produced. Then, via a first automated process step, at least one aperture in the shell part is produced, which then defines an inner face in the shell part. Further, in a separate, second automatic process step, a radial embossing (R) is produced at a peripheral edge formed by an outer shell part surface and the inner face, in that a die with a contour corresponding to the desired radius (r) of the radial embossing (R) is pressed along the inner face against the peripheral edge. The die travels at least once along the complete peripheral edge, thus travelling along a path corresponding to the contour of the edge, such that all the peripheral edge is provided with the desired radial embossing.

NEW SILICONE COLD-EXTRUSION LAMP BELT AND MANUFACTURING METHOD THEREOF

Disclosed are a new silicone cold-extrusion lamp belt and its manufacturing method. The manufacturing method includes the following steps. S10: Select a PCB and use the PCB as a substrate. S20: Set LED lamp bead spot-welding units arranged in an array formed on the substrate to obtain a target board. S30: Extrude a slurry which is formed by a food-grade silicone and coat the slurry on an outer surface of the target board to form a lamp skin. S40: Cut the target board into at least one lamp belt substrate. S50: Heat and bake the lamp belt substrate to obtain a lamp belt. This disclosure has the advantages of feasible design, low manufacturing cost, high resistance on cracking, wearing, yellowing, high/low temperature, good fire resistance, environmental friendly and harmless to human safety, high transparency, high light emitting efficiency of the lamp, and applicable for indoor/outdoor lamp belts.

Process for single-step forming and filling of containers
10189586 · 2019-01-29 · ·

A process for the manufacturing and filling of plastic containers, the process comprising the steps of: positioning a preform with relation to a mold assembly of two or more components, the preform generally being fabricated from a plastic and being provided with a longitudinal axis and presenting a stretchable portion and a non-stretchable portion; stretching the preform along its longitudinal axis; injecting a fluid into the interior volume of the preform, the fluid being under such pressure as to cause the preform to plastically deform until achieving the desired size and shape; and releasing the container from the mold assembly and sealing the container, and in which at least a portion of the stretchable portion of the perform is at a temperature below its vitreous transition temperature (Tg) and, preferably, at ambient temperatures.

Systems For Opening Welded Tubes
20240325710 · 2024-10-03 ·

A tube opening device includes a body having a first side and a second side and including a tube-receiving cavity. The first side of the body includes a first belt system disposed on a first side of the tube-receiving cavity and a second belt system disposed on a second side of the tube-receiving cavity. The first and second belt systems are configured to apply pressure to a tube received in the tube-receiving cavity to open temporary seals and form a continuous tube.

THREE-DIMENSIONAL PRODUCT MANUFACTURING ROBOT FOR PLASTIC FORMABLE MATERIALS
20180126652 · 2018-05-10 ·

A three-dimensional product manufacturing robot using a material constituted by plastic formable materials may be provided that includes: a head supply unit which includes an inlet into which the material is introduced; a transformer unit which includes a plurality of rollers guiding a moving direction of the material transferred from the head supply unit; and a head unit which discharges outwardly the material transferred from the transformer unit. As a result, the tension of a tow, i.e., a raw material can be adaptively controlled and the tow moving within the three-dimensional product manufacturing robot can be prevented from being solidified, cured or degraded. Also, the head unit can rotate precisely within a limited distance. Also, the rotation of the head unit does not accompany the rotation of the tow. That is, while the wheel assembly controls the rotation of the head unit, the tow which passes through the inside of the head unit can be discharged to the outside without rotation.

Apparatus and method for cutting tubular members
09950472 · 2018-04-24 ·

A method of cutting a continuous hollow tubular member having a fully expanded configuration with an outer diameter D, includes the steps of feeding the continuous hollow tubular member in the fully expanded configuration to a cutting station, cutting the continuous hollow tubular member into a plurality of hollow tubular members, each of which has a first flattened end and expanding the first flattened end of the plurality of hollow tubular members to the fully expanded configuration such that the first end of the plurality of hollow tubular members has an outer diameter D.
