Polymer injection molding

Injection molding machine in the basement under the cleanroom

The injection molder at Danchip is an Engel Victory Tech 80/45 which is a hydraulic machine with single motor. The machine is also equippmed with a robot which can pick up finished samples and place them on a conveyor belt. See the table below for key capabilities of this machine.


The user manual, user APV, technical information and contact information can be found in LabManager:

Polymer injection molding Info on LabManager

Polymers

At Danchip the following polymers are used routinely:

  • Topas 5013L-10
  • Topas 8007S-04
  • PP
  • PMMA

Topas polymers are supplied by Danchip. All other polymers are purchased by the users themselves. All polymers (and each individual grade of each polymer) must be approved for use at DTU Danchip. If you would like to use a new polymer or a new grade of a certain polymer, please fill out the New_polymer_application.dotx form which can be found in LabManager by going to the 'Documents' tab of the 'Info' page for the Polymer Injection Molding machine. You can also use this direct link: New_polymer_application.dotx

When the polymer has been approved you will receive labels which must be used to label your polymer. All polymers left in the injection moulding room must be marked with this official DTU Danchip label. Polymers not labelled appropriately may be thrown out at any time.

The easiest way to get an overview of polymers and processes used on the polymer injection moulding machine is to go to LabManager and consult the Process Log for the injection moulding machine. If you would like use a non-Danchip polymer for a test, please contact the owner of the polymer and ask if you can have a sample. A complete list of all polymers in use at DTU Danchip and who owns them can be found in LabManager on the Info page for the polymer injection moulding machine on the 'Documents' tab.
