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 ≤ 1.445 in
    ≤ 1.523 in ≤ 1.445 in
    ≤ 1.038 in ≤ 1.639 in
    ≤ 0.553 in ≤ 1.736 in
    ≤ 1.266 in ≤ 1.891 in ≤ 2.9 in
    ≤ 213.84 mm ≤ 60.38 mm ≤ 36.70 mm
    ≤ 38.68 mm ≤ 36.70 mm
    ≤ 26.37 mm ≤ 41.63 mm
    ≤ 14.05 mm ≤ 44.09 mm
    ≤ 32.16 mm ≤ 48.03 mm ≤ 73.66 mm

  • Our process can support up to four side actions per mold, 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 molds that support simple undercuts are available with our standard lead time of 10-15 business days. In some cases faster deliveries are available.
