摘要:
A manufacturing apparatus for use in the low-temperature high-speed manufacturing of a support structure is introduced. The support structure thus manufactured is for supporting a low-temperature manufacturing scaffold for use in tissue engineering. The manufacturing apparatus includes a frame; a ring-shaped thermally conductive member disposed on the frame; a thermally conductive platform disposed centrally at the ring-shaped thermally conductive member and having an edge in direct contact with an inner wall of the ring-shaped thermally conductive member, wherein a space is defined by and between the thermally conductive platform and the ring-shaped thermally conductive member; a low temperature generating mechanism connected to the ring-shaped thermally conductive member and the thermally conductive platform to cool down the ring-shaped thermally conductive member and the thermally conductive platform; and a spray member disposed above the thermally conductive platform to spray a support material into the space.
摘要:
An injection mold assembly for a high output consumer product injection molding machine, the injection mold assembly having a simplified cooling system that is an evaporative cooling system or a cooling system including a hazardous, dangerous, or expensive cooling fluid. The simplified cooling system has a cooling fluid channel that is confined to a mold support plate.

The present invention relates to a method for manufacturing a shower tray trough, from a composite panel of the sandwich type, to which a mask is applied corresponding to a pattern cavity making it possible to imprint, in the thickness of the foam reinforcing slab of said composite panel, the desired recesses to form said shower tray trough. To that end, the top plate of the composite panel is heated locally, only at the zones corresponding to the recesses to be imprinted, so as to allow the deformation of said top plate and the arrangement of said recesses in the thickness of the foam slab.
摘要:
A bimodal polymer blend of first and second poly(L-lactide-co-glycolide) copolymers, wherein the molecular weight ratio of the first to the second copolymer is at least about two to one, and the blend has crystallization and hydrolysis rates greater than either of the first or second copolymers alone.
摘要:
A staple cartridge is disclosed. The staple cartridge can include a cartridge body, a plurality of staples, and an implantable layer. The implantable layer can include a piece of lyophilized foam and a plurality of fibers at least partially embedded in the piece of lyophilized foam. The implantable layer can further include a plurality of pores defined in piece of lyophilized foam, and a plurality of pockets, wherein a pocket at least partially surrounds a fiber. A method of forming an implantable layer for use with a surgical staple is also disclosed. The method can comprise obtaining a mold comprising a cavity, placing a plurality of fibers in the cavity of the mold, dispensing a solution into the cavity around the fibers, and lyophilizing the solution in the cavity.
摘要:
A method for manufacturing a sheet having a fine shape transferred thereon, in which a sheet base made of a thermoplastic resin is placed between an imprint mold and an intermediate base and the sheet base is then pressed by a pair of pressing plates to imprint the fine shape of surface irregularity of the imprint mold to the sheet-like base. The sheet base is pressed such that, when pressing force of the pressing plates is maximum, an imprinting pressure difference is present in an imprinting surface of the imprint mold, a maximum imprinting pressure section is present in the imprinting surface, and a portion where the imprinting pressure is minimum is not present in the imprinting surface. The method achieves uniform and highly accurate shape transfer without trapping of air.
摘要:
The present invention relates to a method for producing thermosetting components from two or more semifinished composite-material products with textile fibre reinforcement and matrix material, wherein the semifinished composite-material products are fully consolidated, with the exception of local regions, and are brought into contact at the partially consolidated (gelled) regions (201, 211, 221, 241) such that the matrix material of the partially consolidated regions (201, 211, 221, 241) bonds and the regions joined together in this way are subsequently fully consolidated. Furthermore, a device which is suitable for producing the semifinished composite-material products is disclosed.
摘要:
A method for converting a refurbishing machine into a reforming apparatus. The apparatus reforms a portion of a plastic container using induction heating. The method includes the steps of replacing heating assemblies of the refurbishing machine with the reform heating assembly and the reform cooling assembly, respectively, using the existing equipment utilities of the refurbishing machine.
摘要:
In the method of manufacturing a strip (8) of rubber for vehicle tires: a strip (8) of rubber is formed; the strip is cooled with water; residual water (40) on the surface of the strip is heated from the exterior of the strip and/or this water is replaced by hotter water; and the water present on the surface of the strip is eliminated.
