Polymer injection molding
The injection molder at Danchip is an Engel Victory Tech 80/45. It is a hydraulic machine capable of up to 450 kN of clamping force.
The user manual, user APV, technical information and contact information can be found in LabManager:

Process information
There are no standard processes on the injection molder, since the type of process chosen and process parameters will depend on which polymer that will be used and what type of pattern that is to be replicated during the molding process. 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.
