  • Are there any flame retarded plastic for vacuum forming?
    Yes, there are several options; however, they are more expensive and have a longer lead time to obtain.
  • Can you vacuum form a 3D-printed model?
    Models printed with resin can withstand the heat and pressure of vacuum forming; however, much will depend on the shape and dimensions of the model. Even with resin, you will only get a few parts before the model deteriorates. Depending on the shape, dimensions, and number of parts desired, we will make a production mold (or numerous molds) using the 3D-printed model and vacuum form using the production mold(s).
  • Does plastic maintain even thickness while vacuum forming?
    Generally no; plastic stretches while forming causing uneven thickness. There are methods of minimizing plastic stretch to better maintain thickness, but uniform thickness is very difficult to achieve.
  • Can you vacuum form over foam.
    Yes, but on polyurethane foam, not on EPS foams. Lighter the density foams would require a skin and would only produce a handful of parts- usually less than 10. If more parts are needed, a higher density foam must be used or a production mold made from the foam master.
  • How quickly can parts be produced?
    Depending on the quantity, quality, and dimensions, they can be as fast as same-day.
  • Can you use different color plastic?
    The readily-available plastics are clear, white, and black. Plastic color can only be customized (color, pattern, etc.) if the order is large enough to meet the plastic extruder's minimums.
  • Can a vacuum forming mold have undercuts?
    Generally undercuts are not allowed on vacuum forming molds because they cause the plastic to grab the mold preventing release; however, due to our expertise and machine capabilities, some undercuts are acceptable. We would need to discuss them on a per-project basis.
