Storage and Transportation

When you store patterns for a long time, ensure they are in a cool/dry, environment. Prolonged exposure to moisture will damage the parts. Use of desiccant (to extract moisture) in a closed plastic bag will help.

Shipping parts in a sealed plastic bag with desiccant will suffice for most situations. Ensure that parts are “free” and not in contact with other objects. Be aware that the air pockets in plastic bubble wrap will expand during high altitude transportation and pressure may be exerted on your patterns leading to deformation. The use of holding fixtures, constructed of Styrofoam, is highly recommended for large, thin parts. Patterns should have at least one opening to the atmosphere to equalize the pressure changes. Be sure to mark this opening for the foundry’s convenience. It is suggested that you leave the pressure tube (as described in the section entitled “Checking for Holes or Leaks”) open, this will serve as an atmospheric vent and let the foundry re-check vacuum to ensure that there was no damage to the pattern during shipment.


When storing or shipping QuickCast build style patterns, be sure to place the pattern in a sealed bag with an included bag of desiccant.



Under extreme conditions of heat the part may be shipped to the foundry in a Styrofoam box with dry ice. The dry ice will serve two purposes:

  1. Keep the part cool.
  2. Eliminate moisture or condensation. The dry ice should be separated and secured from the part.
Note.png Note: Do not place the dry ice on top of the part, as this will cause the part to freeze.

Large shipping carton with Styrofoam inserts. Note the separate cavity on either side where dry ice may be stored to keep the pattern cool in the hottest, most extreme climates.
