  • 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.

  • Publication number: 20110140311
    Abstract: A thermoplastic injection molding system and method of use is described for molding parts from heated plastics and other organic resins. The machine uses heat sources located along the barrel to heat the source material while an auger screw transports the source material in the barrel. This transport step does not shear the source material, nor does it use friction to produce the heat necessary to melt the source material. The material becomes substantially liquid or melted during the heating process, and the melted material is forced, by the auger screw, into a chamber whereupon a plunger, situated concentrically with the auger screw, injects the material from the chamber into a mold. Sensors located along the barrel and in the chamber ensure consistency between mold cycles. The controller dynamically adjusts the injection molding process to achieve more consistent and reliable molded parts.

  • Patent number: 6846445
    Abstract: A method for rapidly heating a mold cavity to a predetermined temperature preferably above the softening or melting temperature of the molding material prior to and during the molding stage thereby increasing moldability and improving quality of molded parts. The mold cavity is formed by two metallic halves on which high-frequency electric current is applied and an electric circuit involving the two halves is formed. Due to the proximity effect, the electrical current flows on the inner surfaces of the two cavity halves, thus rapidly heating the mold cavity. Proper use of insulation behind the cavity surface helps increase heating efficiency. Conformal on-off cooling channels provide both thermal insulation during the heating phase and rapidly cooling of the molded article during the cooling phase.

  • Patent number: 6797224
    Abstract: A filling system includes a pressurized source of fill material and a pressure fill head wherein the fill head also includes a heating element positioned so as to transfer heat to fill material passing through the fill head. A method of filling holes using a fill material passing through a pressure fill head includes the steps of causing fill material to enter the fill head, modifying the viscosity of the fill material while it is within the fill head, and causing the modified viscosity fill material to exit the fill head and enter at least one hole.

  • Patent number: 6776949
    Abstract: An apparatus and method for bonding polymeric materials is provided. The apparatus and method both utilize ferromagnetic materials in association with the polymeric materials to be bonded together. The polymeric materials, and the ferromagnetic material, are placed within a magnetic field, which causes hysteresis losses in the ferromagnetic field, and thus elevation in the temperature of both the ferromagnetic material and the polymeric materials to the point where the polymeric materials melt and fuse together. The ferromagnetic materials only rise in temperature to their Curie temperatures, at which point the hysteresis losses cease, and the polymeric material stops being heated. Removing the electromagnetic field allows for cooling and fusing.

  • Publication number: 20040046281
    Abstract: This invention discloses a process for rapidly and economically replicating microstructures on polymeric substrates. During the process, a die with protruded microstructures is rapidly heated to above the polymer softening temperature, pressed onto a cold polymer substrate, and subsequently rapidly cooled for die separation. When the heated die contacts the polymer substrate, localized melting occurs at the contacting locations between the substrate and the to-be-replicated microstructure. The resulted melts are confined locally, forming localized spots for compression molding. Bulk deformation of these localized melts results in microstructure replication. In addition to reduction in cycle time, the new process improves dimensional accuracy of replicated microstructures due to uncoupling of microfabrication with macrofabrication.

  • Patent number: 6649114
    Abstract: The apparatus for connecting objects by means of a plastically deformable connecting body comprises a shaping punch (4), a flow-restricting wall (5) closely surrounding the shaping punch and a gas supply lead (6) through which a gaseous medium can be introduced into the gap between the shaping punch (4) and the flow-restricting means (5). The shaping punch (4) has a heating cartridge (8) by means of which the lower end of the shaping punch can be heated. Provided on the outside of this shaping punch are heat-transfer ribs (9) which are used to heat up the supplied, gaseous medium which emerges at the lower end of the flow-restricting means in order to produce a flow around a plastically deformable connecting body (3), so that the latter is uniformly heated for the deforming process. The connecting body (3) is also integrally formed on a part (2) and reaches through a hole in a second part (1) which is to be connected to the first part.
