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.

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 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

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