    Shutoff in Plastic Injection Mould  Shut-Off angle is applied for prevent the mold parts (Core and Cavity) from crashing into one another if there is any slight misalignment upon mold parts closing. Shut-OFF angle also prevent galling that would occur if vertical metal faces were rubbing against each other. Eg.  Note: A draft angle exists for purposes of part release, while a shutoff exi...

  • Injection-molded Part Design
    • 2022-05-24

    Undercut In Plastic Injection Molded Part Design  Undercuts are those features in an injection-molded part that prevent its ejection from the mold. Draft Angle In Plastic Injection Molded Part Design  A draft angle refers to that slant applied to the sides of most features of injection molded parts. Positioning of the injection angles is such that they run towards the direction of the mo...

  • Die Casting Process Advantages and Disadvantages
    • 2022-04-29

    Die Casting Process Advantages and Disadvantages  Die casting: It uses high pressure to press molten metal into the cavity of a precision metal mold at high speed, and the molten metal cools and solidifies under pressure to form castings. Die Casting Characteristics Advantages: 1. During die casting, the metal liquid is subjected to high pressure and fast flow rate 2. Good product quality, st...
