Vacuum Forming Molds

All vacuum forming projects involve a mold.  Due to vacuum pressure, heat, and demolding, V.F. molds will be subject to immense stresses.  We know how different materials perform and exactly how a mold must be made in order to produce as many parts as possible and as efficiently as possible.  A poorly-designed mold will severely impact production time and cost. 

When only a few simple parts are needed, a hand-built MDF or carved foam mold will suffice, sometimes with an ABS skin. However, for higher quantities or detailed molds, we use urethane, heavy foam or tooling board, fiberglass, or aluminum.  We know which materials to use for which kinds of projects.  We also understand some clients prefer to make their own molds to reduce costs; please call us before you start on your mold, our insight and experience will save you time and money.  Better yet, avoid the headache and let us make your molds for you.

Urethane Molds

Certain urethane resins can be extremely hard, withstand high temperatures, and are capable of providing hundreds of parts.  The process involves taking a printed or machined "master," taking a silicon mold, then casting the urethane out of the silicon.  This is one of the most common materials for vacuum forming molds.

Foam Molds

CNC machined foam is a faster and cheaper alternative to urethane.  The number of parts required will dictate the density of the foam used (4lb-72lb) and the production material will dictate the secondary finish required, i.e. poly-prime. 

Aluminum Molds

When you need parts by the thousand and each one needs to be perfect, a CNC-machined aluminum mold is your answer.  

Fiberglass Molds

During normal vacuum forming, the plastic is pulled over a positive mold.  However, when the part is very deep or requires perfect detail, a negative mold is required.  These can be made using a variety of methods, but require special expertise.
