摘要： PURPOSE:To reduce the baking time and make it possible to perform the baking treatment which does not generate the surface deformation by a method wherein a cost of fluoroplastic or liquid crystal resin, which is molded onto the surface of an aluminum alloy rotor by injection, is heated by high frequency currents through a press jig. CONSTITUTION:Fluoroplastic 3 with a thickness of about 0.5mm is molded on the periphery of a aluminum alloy cast rotor 2 by injection. IN order to fill up a gap 6 produced between the surface of the aluminum alloy rotor 2 and the fluoroplastic 3, the rotor is shifted through a press jig 7 consisting of asbestos in the direction indicated with the arrow so as to generate heat 9 locally and in the small range on the surface of the rotor by means of a high frequency coil 8 in order to fill up the gap 6 by melting a part 10 of the resin 10. Because the resin layer is heated by high frequency currents through the press jig 7, neither 'blister' nor 'scaling' develops in the resin layer, and the rotor and the resin layer completely adhere to each other. In addition, the aluminum alloy rotor is in the form inserted in the resin layer, and both the end parts 3a of the rotor do not become dull but make sharp corners, resulting in developing no leakage at the pressure feeding of air.

摘要： PURPOSE:To enable to obtain a high-quality molded article in a comparatively short period of time, by a method wherein a large number of slits is provided in an axial direction by machining on the inside of an end of a heating cylinder, where feed of resin is commenced, a double flight screw is provided with a main flight and an auxiliary flight having a larger pitch than that of the main flight and a cooling cylinder is provided on a heater zone of the heating cylinder. CONSTITUTION:This resin 5 enters into a groove (a) of a screw 2. Although the resin 5 entered into a groove (a') is unmolten resin, as the more the groove (a') moves leftward the more a width of the groove narrows, the unmolten resin is compressed. In this instance, the unmolten resin 5 is entered into a groove (a'') through a gap. When the resin 5 passes through the gap, a temperature of the resin 5 becomes identical with a setting temperature of a heating cylinder 1, an uneven temperature and blotches of color of the resin 5 are eliminated and the resin 5 is turned into a molten resin through compression. It becomes that the resin 5 is turned into the molten resin in the groove (a''), stored in a storage chamber A and injected from a nozzle B. Control of temperatures of each of heater zones H1, H2, H3 is made by cooling cylinders 18, 19, 20. When a temperature of the heating cylinder 1 is raised, it is adjusted by actuating a cooling blower 21.

摘要： PROBLEM TO BE SOLVED: To close off a gas inflow port without increasing cost by injecting resin again after gas injection molding and closing off the gas inflow port. SOLUTION: Gas is injected from a gas gate 9 so as to make resin within the cavity 3 into a hollow shape. Molten resin is injected from the injection molding machine 1 and comes into the cold runner 5 from the second gate 6 to be filled in the hollow part. At this time, since the check valve within the gas nozzle 8a comes to be in a closed condition, molten resin does not comes into the gas nozzle 8a. In addition, molten resin comes into the hollow part of the cavity 3 via the first gate 4. In this instance, resin coming into the cavity 3 does not need to fill the hollow part, thus it is sufficient to be a quantity capable of closing off the first gate 4.

摘要： PURPOSE: To reduce mold clamping force at the time of the molding of two split members constituting a hollow product by opposing first and second cavities to each other and injecting a molten resin into those cavities in this state to mold respective split members. CONSTITUTION: At first, first and second movable molds 2, 4 and a moving core are arranged so that first and second cavities C1, C2 are opposed to each other and the moving core is held between the first and second movable molds 2, 4 by predetermined mold clamping force. In this state, a molten resin is injected into the first and second cavities C1, C2 opposed to each other under predetermined injection pressure by an injection device. The mold clamping force at this time may be only the force corresponding to (projection area of either one of the first and second cavities C1, C2)×(injection pressure) and this clamping force may be half that in a conventional method. Next, the first and second movable molds 2, 4 and the moving core 7 are cooled by water and the molten resin in the cavities is solidified to simultaneously mold two split members 11, 12.

摘要： PURPOSE: To simplify the structure of a front part, and to reduce the cost by pouring the gas or the volatile liquid in the formed material when a housing is extruded to form a hole where a driving cable is slidably guided. CONSTITUTION: A hole for the cable guide is formed in a front frame, and used as a passage where each cable is slidably guided. The resin is extruded in a cavity 41 of dies 40 where a formed product is formed, and then, the pressurized gas is fed in the resin from a gas injecting hole 42 to form a hole. The pressurized gas sufficiently hardens the resin and cools it so that the shape made by the cavity may be kept b the formed product itself, and the hole is formed by reducing the pressure in the hole before the dies are opened. The pressurized gas expands the hot part of the resin in the vicinity of the inner part of the resin to form the hole while the resin is pressed against the inner surface of the cavity.

摘要： PURPOSE:To make resin into a low abrasion loss by using such one that is made up of mixing polyester resin, Teflon resin and polyester elastomer as the resin for a Roots pump slide rotating part. CONSTITUTION:Liquid crystal polyester resin, Teflon resin are mixed in a glass fiber and this mixture is applied to an outer circumferential surface of a rotor of a Roots pump and both the end faces closely and molded by means of injection molding. Accordingly, with the elastomer added, it is able to lower the hardness even if a Teflon component is increased, thus abrasion resistance is improvable as a resin material.

摘要： PURPOSE:To enable low temperature plasticizing, by a method wherein at the beginning of a commencement of molding a heating cylinder temperature is set at a high temperature and a feed quantity is reduced and after the lapse of a predetermined period of time after the commencement of the molding, the plasticizing is controlled by changing over automatically the temperature of the heating cylinder to a low temperature and a counting feeder a fixed quantity. CONSTITUTION:At the time of extremely low temperature plasticizing, a speed of a driving source 16 is made into a high one and the plasticizing is done by setting temperatures of heater zones H1, H2, H3 at 190 deg.C, 180 deg.C, 170 deg.C respectively. Then at the beginning of a commencement of molding, a feed quantity of resin is controlled at about 30% by making a speed of a driving source 16 into a low one, and the molding is done by making a setting temperature into t4, that is, 200 deg.C by changing to a temperature adjuster 12 for high temperature in the heater zone H3 at the tip. With this construction, as the setting temperature of a heating cylinder is low and a feed quantity is large, a trouble through which a rotation of a screw becomes impossible through entering of unmolten resin into a space between a screw groove and a barrel in a wedgy state can be prevented from generating.
