Patent EP-0380688-A1 (EP)
Inventor: UEHARA TADAYOSHI
IPC: B29L11/00
Filed: 1989-07-14
Abstract: In an injection molding method involving pressing for producing a molded article by injecting a plasticized and measured thermoplastic resin into cavities through a sprue - runner - gate and cooling it with a mold clamping force applied, the present invention provides a method for preventing the oc- curence of weld marks, non-uniformity of injected resin quantities among a plurality of cavities, photoelastic strain, flow marks, and the like. A cavity formed inside the mold is in advance expanded to a volume sufficient to prevent a branch flow of inflowing resin and is kept at a temperature sufficient for the resin to keep a fluidization state. The thermoplastic resin which is heated and is under a molten state is preparatorily measured and injected into this expanded cavity in quantity greater than necessary for obtaining a molded article. Before the full quantity of this thermoplastic resin measured in advance is injected into the cavity, the cavity is diminished. At the point of time when the cavity is diminished to a sum of the volume of the molded article and the mold shrinkage quantity of the thermoplastic resin due to cooling, this diminishing operation is controlled in such a manner as not to leave any uncharged portions inside the cavity which would cause flow marks. At the time of its diminution, the injection pressure is lowered to a pressure at which the backflow of the thermoplastic resin, which might have been over-changed into the cavity, from the cavity due to the diminution of the cavity is not prevented and the resin can be injected to the uncharged portions where the resin might remain inside the cavity. The sprue is cut off when the behaviour of the resin inside the cavity goes stable, and the resin injected into the cavity is cooled and hardened under pressure to a withdrawing temperature.

Abstract: The invention relates to a process for heat setting a biaxially oriented polyamide film, which comprises heat setting a biaxially oriented film having a low anisotropy in hot water shrinkage ratio in a flat state, if desired, after preheating treatment, by heating the film in a temperature range of 40 to 10° C lower than its melting point in close contact with the surface of a heated material with both ends of the film clamped, and cooling the film to a temperature at which the film is not deformed easily. The invention also relates to a biaxially oriented polyamide film which has a hot water shrinkage ratio at 100° C of up to 5.0 % in all directions at all positions in the transverse direction and an anisotropy H (%) in hot water shrinkage ratio calculated according to the equation a of up to 30%, preferably up to 20%, wherein S 45  and S 135  represent hot water shrinkage ratios at 100° C in the directions at angles 45° and 135° left from the machine direction, respectively. This film is one which could not be obtained by the conventional tenter process, etc.

Abstract: An automatic wire connecting method capable of carrying out a wire connecting operation reliably and smoothly irrespective of the diameter of a processing starting bore even when a low-priced apparatus is used. In order to carry out a wire connecting operation via a processing starting bore of a regular diameter, a wire electrode is fed from a wire connecting nozzle (120), which is attached to an upper wire guide (30) so as to be spaced from a work (50), toward the work as a working fluid is ejected thereto. Consequently, the wire electrode is inserted reliably into a processing starting bore (51) and a wire passage in a three point-supported guide (72) contained in a lower wire guide, owing to the wire guiding effect of the jet of the working fluid. In order to carry out a wire connecting operation via a processing starting bore of a small diameter, a wire connecting nozzle (120) having a nozzle bore (125) the diameter of which is smaller than that of a small-diameter processing starting bore (51) is attached to the upper wire guide so as to be positioned close to a work. When a wire electrode is fed via the nozzle with the working fluid not supplied to the work, it is inserted into the small-diameter processing starting bore close to the nozzle, and then into the wire passage in the lower wire guide owing to the wire guiding effect of this processing starting bore.
