摘要： In a process for blow molding of a thermoplastic resin parison by using a mold, the resin is blown and molded in the mold while a local part of the mold is heated for a short period of time to elevate the temperature thereof above the temperature of the parison itself but up to the vicinity of the melting point thereof so that the temperature of the surface layer of the parison in contact with the local part of the said mold may be made higher than that of the parison body itself, and thereafter the resulting molding is taken out from the mold after cooling and solidification. In the present blow molding process is used a specific blow molding apparatus in which the surface of a mold body in the local part thereof is electrically insulated and an electric heating element is provided on the said insulated part in the form of a coating film or of a thin layer mold, the said heating element being able to heat for a short period of time during molding.

摘要： A method for effecting vacuum evaporation onto extremely thin and whippy thermoplastic films. In the method, a laminated film is prepared consisting of a first layer of a film to be metallized and a second layer of a base film. The laminated film is subjected to elongation at least uniactially at a temperature below the melting points and above the second degree transition points of the materials of the two films. The laminated film thus elongated is then processed by conventional vacuum evaporation.

摘要： Apparatus for the continuous manufacture of containers from a thermoplastic resin, comprising three rotaries; a parisontransferring rotary, a blow-molding rotary and a rotary for removal of the product and for pinhole test. The first rotary is arranged as a rotary-type transferring device between the molding machine and the extruder, in which the continuously extruded tubular parison is continuously stretched and cut to a desired length, and this cut parison, after rotation thereof by 90*, is inserted into one of the metal molds in the point of contact with the second rotary being a blow molding rotary, whereby the waste of material as in the conventional rotary blow molding machines can be eliminated. The second rotary is equipped with several or dozens of sets of metal molds and their tightening means. These metal molds are synthetic resin blow-molding ones in which sealing of the product and utilization of the material can be performed efficiently. In this case, two sets of split molds are combined with their container bottom-forming portions opposed to each other and a blow pin is arranged between said bottom forming portions so as to form two containers at a time, and a pressing mechanism for closing the top of the container and adapted to be movable at right-angles to the split face of the mold is provided, thus improving the operational efficiency and reducing remarkably scraps in the ranges of the top and bottom of the container. Normally, in the case of resins from which narrownecked containers cannot be made by blow molding and biting off as in the case with vinylidene chloride, only large necks than the diameter of the parison can be formed. Of course, it is possible to make the diameter of the neck substantially equal to or smaller than that of the parison by arranging any guide at the position of the neck, but this leads to reduction of the yield by an amount corresponding to the width of the guide. According to the present invention, the parison is pressed in a direction perpendicular to the split mold, thereby to realize the same effect as that of the guide and moreover to enable the container to be sealed tight enough to prevent penetration of bacteria. In order to facilitate sealing of the container at the bottom immediately after blow molding, high frequency electrodes may be provided at the bottom-forming portion of the metal mold. The so produced container is taken out from the mold by grasping it at the portion grasped for transfer from the first to the second rotary, as soon as the mold is opened at the point of contact with the third rotary. Then, the unnecessary portion between the bottoms of two containers is removed by a bottom cutter while air-cooling them and at the same time the body of the sealed container is compressed with a certain pressure to check it for freedom from pinholes. Finally, the finished containers are sorted as acceptable or not an are made to fall down.
