摘要:
To easily cut CFRP, a metal mold for CFRP component includes a stationary blade that stands still in contact with one surface of a CFRP material made of a carbon fiber reinforced plastic, and a moving blade arranged at a moving blade surface side of the CFRP material, the moving blade surface being a surface at an opposite side to a stationary blade surface, the stationary blade surface being a surface of a side where the stationary blade is positioned, and adapted to cut the CFRP material by being moved from the moving blade surface side to the stationary blade surface side and providing shear force to the CFRP material together with the stationary blade.

The invention relates to such a method and apparatus, as well as to the resulting deformed object out of a relatively hard material such as e.g. a metal or plastic wire in which an undeformed section (2) is clamped near its ends (3, 4) and is subsequently upset in a controlled way by an axial pressure force (22) to a predefined shortened and thickened longitudinal section (5), with which simultaneously over substantially the entire contour sheath (19) of this section (2) a counterforce (29) is exerted so that, with the progressive deformation during upsetting, the total volume of the longitudinal section that is deforming, remains substantially constant. In this thickened section (5) a flattened zone (8) can subsequently be applied in order to realise a final shape (10) such as an opening (26). The invention concerns in particular also the use of a deformation line (40) for manufacturing a heddle for weaving looms.

A method of treating a hole formed in a catheter includes providing the catheter with an opening formed in a wall of the catheter from an external surface of the catheter to an internal surface of a lumen of the catheter such that the catheter has a sharp external edge formed between the external surface and the opening and a sharp internal edge formed between the opening and the internal surface of the lumen of the catheter. The method additionally includes pushing a proximal end of a mandrel into the opening formed in the wall of the catheter and rounding the sharp external edge of the opening formed in the wall of the catheter with a distal end of the mandrel. The method further includes maintaining the sharp internal edge formed between the opening and the internal surface of the catheter.
摘要:
A method for rounding at least a part of an edge of an opening in a tubular body formed of thermo-formable material, wherein a mandrel is brought into contact with the edge and the mandrel has a temperature that allows it to permanently deform the material of the tubular body and a product thereof.
摘要:
To obtain a close-contact multi-layer type diffractive optical element having a homogeneous high-refractive-index and low-dispersion resin layer, an acrylate-terminated oligomer, obtained by allowing excess bifunctional acrylate to react with bifunctional thiol, is used as a resin precursor for the high-refractive-index and low-dispersion resin layer.
摘要:
A bowl-shaped container (10a) which is as a biodegradable molded article adheres a coating film (12) mainly made of biodegradable plastic and having at least hydrophobicity to the surface of the main body (11a) of the container mainly made of starch. The main body (11a) is molded through steam expansion of a slurry or dough molding material containing high-amylose starch and water, or a slurry or dough molding material containing starch, polyvinyl alcohol and water. For these reasons, it is possible to accomplish sufficient strength and at least sufficient water resistance, to exert a very excellent biodegradability and further to provide a biodegradable molded article having excellent moisture absorption strength mainly made of starch even if the biodegradable molded article has a complicated shape.

A method and apparatus are provided which enable formation of a thermoplastic article having a high volume loading of a long fiber reinforcement. The method includes providing a first thermoplastic composite material having at least about 40 volume percent of at least one reinforcing fiber; providing at least one mold, the mold(s) each comprising at least one first mold section having an inlet and an outlet and defining a first mold cavity and at least one second mold section having an inlet and an outlet and defining a second mold cavity, wherein the outlet of the first mold section is in communication with the inlet of the second mold section; introducing the first thermoplastic composite material into the first mold cavity; applying heat and pressure to the first thermoplastic composite material in the first mold cavity until the first mold section reaches at least a first process temperature; releasing the pressure on the mold; and reapplying pressure to the mold while cooling, wherein at least a portion of the first thermoplastic composite material flows out of the least one outlet of the first mold section and into the second mold cavity, wherein said cooling solidifies the first thermoplastic composite to form a molded article having the shape of the second mold cavity. Articles formed from such methods and apparatus are also disclosed.
摘要:
In a method for molding a resin piston by charging a preheated resin tablet into a cavity of a molding die, and by carrying out compression molding while heating, at a time point when an internal pressure of the cavity arrives at a determined pressure, by pressurizing a pressurizing margin in the molding die, resin which overflows from the molding die is discharged from a passage which is defined in an area except an outer circumferential surface of the piston, while the internal pressure of the cavity is maintained. After a thermosetting cycle has finished, the molding die 21 is opened.
