  • Publication number: 20150054199
    Abstract: Heated mould cavities of injection-moulding dies require long heating and cooling phases, with the result that the production unit numbers are low, the unit costs are high and the degree of efficiency is low as a result of the energy for temperature control. It is therefore a problem of the invention to eliminate or to reduce these disadvantages. According to the invention, this is solved by virtue of the fact that a die insert for delimiting, at least in sections, a mould cavity which is configured in a moulding plate of an injection-moulding die for producing components from a flowable material is provided with a main body which has a shaping front side for the mould cavity and a rear side which lies opposite the shaping front side, wherein the main body carries a layer heating means on the shaping front side thereof.

  • Patent number: 8727761
    Abstract: A die for an underwater cutting type pelletizer, the die including a die orifice part in which a thermoplastic resin is inhibited from solidifying within the die orifices. The die can have a reduced difference in temperature between the die orifice part and an inner periphery-side fixing part for fixing the die orifice part to a mixer/extruder, and can thereby inhibit the generation of thermal stress. The die is characterized by being equipped with a heating jacket for heating the inner periphery-side fixing part, the heating jacket being disposed within the inner periphery-side fixing part along an inner annular passage formed within either the die orifice part or the inner periphery-side fixing part or both along the boundary between the die orifice part and the inner periphery-side fixing part.

  • Patent number: 8696338
    Abstract: An apparatus for manufacturing a capsule by using vegetable gelatin is provided. Heating units are installed in a gelatin feeding line, which feeds gelatin in the form of a sheet, and a molding line to feed the gelatin in a predetermined temperature. The molded capsule is conveyed through a conveyer so that the molded capsule is stably dried and cured and a temperature of the conveyer is adjusted to control a temperature of the capsule. A length of the drying line is maximally increased within a narrow space, so that a film of the capsule made of the vegetable gelatin is gradually cured and dried without abrupt temperature variation, thereby preventing crack from occurring in the capsule, and preventing bonding parts of the capsule from being torn to improve the commercial value of the capsule.

  • Publication number: 20140099397
    Abstract: An injection molding system is disclosed that utilizes a melt channel wherein at least a portion of the melt channel has a noncircular cross-section for balancing shear in a melt stream of moldable material that flows therethrough. The noncircular cross-section of the melt channel portion may be, for e.g., capsule-shaped, extended egg-shaped, oval, teardrop-shaped, or peanut-shaped. A flow splitter is also disclosed that is positioned offset from a central axis of an upstream melt channel to protrude between inlets of respective downstream melt channels, where the upstream melt channel splits into the downstream melt channels, to thereby create a narrower inlet into one of the downstream melt channels and a wider inlet into the other of the downstream melt channels.

  • Patent number: 8628322
    Abstract: A mold apparatus used in injection molding of liquid silicone composition. The mold apparatus is made of several components aiding in the overall process. The mold apparatus has two main sections, a cold section to prevent the liquid silicone from curing and a heated section for curing the liquid silicone. The two sections are separated by a thermal insulating plate. The metering of the flow is achieved by an actuator providing linear movement of a valve pin position in the center of the flow path of the runnerless nozzle resting against a gate orifice. The runnerless nozzle is keep cooled with an annular heat pipe surrounding the body of the runnerless nozzle and circulating a liquid coolant at one end of the runnerless nozzle. The cavity block receive heat from an heating element incorporated in the cavity back plate. Heat is evenly distributed in the cavity block by vaporization.
