摘要:
A first mold has a recessed surface portion. A second mold that has a protruding surface portion and a flat surface portion is laid on top of the first mold, thereby forming a first cavity between the recessed surface portion and the protruding surface portion and a second cavity between the first mold and the flat surface portion. The first cavity and the second cavity are filled with a first resin material. A third mold having a flat inner wall surface is laid on top of the first mold and the first resin, thereby forming a space between the inner wall surface and the first resin so as to correspond to the protruding surface portion. This space is filled with a second resin material, and thus an acoustic coupling member is molded.

The present invention involves tissue engineering constructs made from a new composite bone graft material made from biocompatible poly(D,L-lactic-co-glycolic acid) (PLGA) and bioceramic particles exposed on its surface using a gas foaming particle leaching (GF/PL) method and infused with collagen. Methods and apparatus for of forming scaffolds are also disclosed.

A large area patterned film includes a first patterned area; a second patterned area; and a seam joining the first patterned area and the second patterned area, wherein the seam has a width less than about 20 micrometers. A method for tiling patterned areas includes depositing a predetermined thickness of a curable material; contacting a first portion of the curable material with a mold; curing the first portion of the curable material; removing the mold from the cured first portion of the curable material; contacting a second portion of the curable material with the mold, such that the mold contacts a portion of the cured first portion of the curable material; curing the second portion of the curable material; and removing the mold to yield a seam between the cured first portion of the curable material and the cured second portion of the curable material, wherein the seam has a dimension less than about 20 micrometers.

A luggage case includes a case woven by thermoplastic composite material, the case includes four integrally connected lateral walls, a bottom connected to the lateral walls, and four arc-shaped corners at cross points of the lateral walls, between each of the arc-shaped corners and the bottom is defined a closed hole. Any two of the lateral walls which are neighboring to each other are provided with a first overlapping portion and a second overlapping portion, respectively, and the first and second overlapping portions are integrally connected to each other without a notch formed therebetween, each of the corners of the case is folded to make the first and second overlapping portions overlapped with each other, so as to form a thickened pieces on an inner surface of each of the lateral walls.

The invention is directed to a process for making a golf ball having a multi-layered cover including a very thin outermost cover layer, the process comprising for example: forming first and second substantially hemispherical half shells having a thickness and comprising a thermoplastic composition, each half shell further having an outer surface and an inner surface, the inner surface forming an hemispherical cavity; securing the first half shell in a golf ball mold; securing a core subassembly in a subassembly holder; dispensing an uncured liquid thermoset composition into the hemispherical cavity of the first half shell; inserting a first half of the core subassembly into the hemispherical cavity of the first half shell and displacing an amount of the uncured liquid thermoset composition such that the uncured liquid thermoset composition forms an inner cover layer having a thickness; disengaging the core subassembly from the subassembly holder when the thermoset composition has gelled to a point of rigidity; securing the second half shell in a golf ball mold; dispensing the uncured liquid thermoset composition into the hemispherical cavity of the second half shell; inserting a second half of the core subassembly into the hemispherical cavity of the second half shell and displacing an amount of the uncured liquid thermoset composition such that the uncured liquid thermoset composition forms an inner cover layer having a thickness and thereby mating the first and second half shells; and curing the thermoset inner cover layer to complete the golf ball and then removing the resulting golf ball from the golf ball mold.
摘要:
The invention is a method to make compression molded motor vehicle parts from a charge of composite material with resin and fibers, such as sheet molded compound. The parts have voids, such as holes and gaps, that form in the compression mold under heat and pressure and not in secondary processing steps. The resin in the charge is melts in a reservoir in the mold to form resinous material from the charge. A flow front of resinous material is allowed to flow into a flow path around a restriction corresponding to the shape of the void from the reservoir. The flow front carries sufficient reinforcing fibers into the flow path. At least part of a border for the void forms in the flow path. The configuration is allowed to at least partially set.

Method for forming an item through compression-moulding having an asymmetrical section with differentiated volumes and thicknesses, comprising the steps of introducing a dose of semi-liquid resin into the recess of a mould, inserting a plunger in said recess to create the interspace intended to be occupied by the material pushed by the plunger, removing said plunger and withdrawing the item that stays stuck to the plunger or to the recess, where the interspace intended for the forming of the item is created in two successive steps, the first comprising the insertion of a first plunger into the recess, and the second comprising the action of a second plunger that acts in a portion (accumulation chamber) of the interspace created by the insertion of the first plunger, completing the creation of the interspace in which the item is formed.
