    Abstract: A mold for traffic cones has a female mold, a male mold and two cavities. Because each first annular recess of the female mold and a corresponding second annular recess of the male mold can hold a base of the traffic cone steadily, the female mold does not have to be placed under the male mold. Then the sprue can be formed through the female mold and can be nearby the two cavities. Besides, the distributing recess of the male mold communicates with the sprue and the second annular recesses. As a result, a liquid plastic material injected from the sprue is distributed and flows into the two cavities. After the male and the female molds are separated, two traffic cones are completed. Therefore, the mold for traffic cones as described can make two traffic cones at a time, which raises manufacture efficiency.

  • Publication number: 20130221572
    Abstract: A low constant pressure co-injection molding machine forms molded parts by injecting molten thermoplastic material into a mold cavity at low constant pressures of 6,000 psi and lower. As a result, the low constant pressure injection molding machine includes a mold formed of easily machineable material that is less costly and faster to manufacture than typical injection molds. Co-injection of thin-walled parts having an L/T ratio>100, with embedded sustainable materials, such as polylactic acid (PLA), starch, post-consumer recyclables (PCR), and post-industrial recyclables (PIR) isolated from surfaces by barrier layers of leach-resistant material having a thickness less than 0.5 mm, is possible.

  • Patent number: 8485812
    Abstract: Methods and systems for fabrication of injection molded optical components. In one embodiment, a moldplate with cavities receives injected optical material within walls of the cavities. The cavities are designed with a geometric profile approximately corresponding to a optical profile of an optical element to be formed therein. When molten optical material is injected into the cavities of the moldplate, the injected optical material forms a meniscus due to surface tension between the optical material and the wall of the cavities. The meniscus thus provides a shape corresponding to the predetermined optical profile. The optical material is then rapidly cured with actinic radiation, and a desired optical element with high-precision dimensions is formed within the cavities of the moldplate. In some embodiments, the moldplate is spun such that the meniscus is adjusted to match the predetermined optical profile within a certain tolerance.

  • Patent number: 8469697
    Abstract: A rotary molding system for molding food products, mold cavities formed when a mold shell rotates mold shapes disposed along the mold shell into a fill position between a fill plate and a wear plate. Molded food products are removed from mold cavities using knock-out cups, the use of air pressure, or the use of a vacuum source disposed below the mold cavity, without the need to slow the rotation of the mold shell. Knock-out cups may be used with a heating system to reduce accumulation of unwanted materials on the knock-out cups. The rotary molding system can also be used to form products with contoured surfaces. A smart tagging system can be used to ensure that compatible sets of mold shells and knock out cups are being used. A vacuum region may be disposed upstream of the fill position to remove air within the mold cavity prior to filling.
