Make: Formech

Model: 508DT

Serial Number: 2728

Ace: Needed (Makerhub@georgefox.edu).

Location: The Vault


Description

The Formech 508DT Vacuum Former is a plastic molding machine that utilizes heat and a vacuum to stretch heated plastic over a mold. The vacuum former is great for thin plastic molds, although there are some limitations on the shape and size. The max dimensions for the mold are 17”x19” with a depth of 7.3". The max thickness for the plastic sheet is 0.25" Molds can be made from many types of materials. It's fairly common to see molds made from wood. Molds need to have some draft so they can be removed from the plastic.


Here is an example of this piece of equipment being used.

Documentation

Terminology

  • Table- The bed that the mold rests on.
  • Clamp Frame- The metal bars that captivate the plastic sheet as its heated and stretched over the mold.
  • Toggle Clamp Screws-
  • Draft Angle- The wall angle of a mold. This helps in removing the plastic off the mold.

Knowing what the different buttons in the touchscreen operation mean is important in operating the vacuum former. The three primary ones are heat , vacuum , and release . For a full list, refer to the manual.

Vacuum Former User Manual

Vacuum Forming Guide

Training

Operation

The vacuum former can mold up to a 19"x17" square and to a depth of 7.3".

Molds must slant outwardly slightly to ensure that they can be popped out of the plastic after molding is finished.

Demonstration

The demonstration for the vacuum former can use one of the provided demonstration molds or a mold that the trainee brings. The trainee must show that they can set up the vacuum former and mold a part.

Operation

Formech Controls.JPG

Operation

  • Place a mold into the tray and lower it.
  • Mold cannot be concave and must slant outwards slightly or it will not be removable from the plastic.
  • Place plastic into the clamps ensuring it completely covers the white seals.
  • Turn on the heaters and set the temperature. The temperature should be 80-120 degrees Celsius.
  • The heaters should take about 15 minutes to warm up.
  • After 15 minutes roll the heater over the plastic
  • Allow the heater to sit over the plastic for 90 seconds if the plastic is 1.8mm thick or 180 seconds if the plastic is 3.3mm thick.
  • DO NOT OVERHEAT PLASTIC! this will cause the plastic to develop webbing after the vacuum which will ruin the mold.
  • Lift the table.
  • Turn on the vacuum.
  • Let the plastic cool, then hit the release button.
  • Lower the table to remove the plastic.
  • Reset the table.

Safety

  • Parts of the machine can reach over 300 degrees C. Don't touch the heater or heat shield surrounding the heater.
  • Never put your hand in a position it could be pinched by the molding frame.
  • The formed plastic is very hot and sticky. It could stick to you and continue to burn if you touch it.
  • Some types of plastics could give off toxic fumes when heated. Check the SDS before working with materials you are unfamiliar with.
