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.

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.
摘要翻译：目的：为了在相当短的时间内获得高质量的成型品，通过在加热缸的端部的内侧通过机械加工在轴向方向上设置大量狭缝的方法，其中进料树脂开始，双螺杆螺杆设置有主飞行和辅助飞行，其间距大于主飞行，并且在加热缸的加热器区域上设置冷却圆筒。构成：该树脂5进入螺杆2的槽（a）中。虽然进入槽（a'）的树脂5是未熔化的树脂，但是随着槽（a'）越向左移动越多，槽变窄，未熔化的树脂被压缩。在这种情况下，未熔化树脂5通过间隙进入槽（a“）。当树脂5通过间隙时，树脂5的温度与加热筒1的设定温度相同，不均匀的温度和树脂5的颜色斑点被消除，树脂5变成熔融树脂通过压缩。成为树脂5变成槽（a“）中的熔融树脂，储存在储存室A中并从喷嘴B喷射B.每个加热器区域H1，H2，H3的温度控制由冷却缸18,19,20。当加热缸1的温度升高时，通过致动冷却风扇21来调节。
