  • A Typical Injection Mold Design Guide
    This checklist can be used as a general reference guide for injection mold design engineers. It is divided into 3 parts of a mold design process. A Typical Injection Mold Design Guid ---by Elito << Amelia Hu s Blog. Amelia Hu s Blog. B2B Marketing & Social Networking. Home. About Amelia. Home
  • SPI: Mold Classifications
    to prevent corrosion. Parting line locks are required on all molds.  . CLASS 102 MOLD   Cycles: Not exceeding one million Description: Medium to high production mold, good for abrasive materials and/or parts requiring close tolerances. This is a high quality, fairly high priced mold. Detailed mold
  • Case Study: Machining - VMC for Real-World Moldmaking and Milling - 04/08
    SHM is a moldmaking business within a 2,500-square foot facility that specializes in compression, transfer and injection molds for the rubber industry. According to Jack Latragna, owner of SHM, rubber molds are different than plastic molds in that they can be undercut and don't need slides, so
  • white paper: Shoulder Screws
    to specify shoulder screws when used in punch and die mechanisms or plastic. injection mold sets. The screws act as linear slides to accurately align the die or mold halves as they. open or close. Drive Types: Commercial grade, alloy steel shoulder screws are supplied almost exclusively with Hex Socket
  • Material and Process Selection, Controlling the Stretch, Industry Standards
    process and material. A rubber mold consists of two or more custom-tooled steel plates carefully registered to ensure consistent close tolerances and appropriate surface finish. The line where the two molds meet is called the parting line. Sometimes the presence of a parting line is objectionable
  • The weak link in reinforced nylons
    . In fact, knit lines have about the strength of unfilled resin. Moldflow software from Moldflow Corp., Wayland, Mass., simulates liquid plastic flowing into an injection mold. This helps designers predict where knit and meld lines are likely to form. Areas colored red take the least time to fill
  • Electroform Company: Flying High
    , his specialty was in the aircraft industry, which afforded him a great deal of high-precision, close-tolerance work. "This set the tone and quality and inspection involved in our work through the present day," Clark notes. Although Electroform ceased aircraft and custom EDM in 1991, that allowed

    and silencers, microphone attenuators. 6.) Gas Distribution and Sparging;. i.e., fluidized bed surfaces, air bearings, vacuum plates, spargers for. carbonation, oxygen stripping, ozone injection. 7.) Media Retention;. i.e., permeable barriers for desiccants, getters and purifiers. Important design
