Side Action Support for simple undercuts

The Protomold process supports simple undercuts in your part geometry. Here are some specifics you will need to keep in mind:
  • The maximum side core dimensions are summarized in the following tables:

    Width Height Pull
    ≤ 8.419 in ≤ 2.377 in ≤ 2.900 in
    ≤ 213.84 mm ≤60.38 mm ≤73.66 mm

  • In certain circumstances Protomold can manufacture tools with a 73mm side action pull length.
    Our process can support up to four side actions per mould, and they all need to be at the parting line. Side pulls must be perpendicular to the primary (A-B sides) pull direction.
  • Side Action moulds that support simple undercuts are available with our standard lead time of 15 business days. In some cases faster deliveries are available.
