    mold making and aluminum concerns

    I'm working on a project where i am CNC'ing a 2 part mold out of MDf. The mold is about 1 foot x 2 feet. The mold itself has a few contours. The deepest of the contours goes down about 1.5 inches. I am looking to use this mold to press aluminum but I am not sure what type of aluminum i need. I am using a hydraulic press and the finished piece. The piece does not need any extreme strength as it is being used a decorative piece for the most part. Any suggestions? if im not explaining things enough or clearly please let me know so i can explain...... im new to this.

    have talked about doing this. They make the die/mold then stack polyurethane rubber sheets and a steel plate and then press.

    The urethane deforms down into the sheet metal and forms the design into the die. If making more than a few pieces you might consider a metal die, the MDF wears fast. The detail fades after a few parts.

    Depending on the die geometry, 3003-H14 will probably be your best choice, though 1100 has slightly better formability.
