Injection molding inserts
Characteristics:
Master with a thickness range 3 - 8 mm are being used on injection molding machines. Preferably called: “ Inserts ”. Large area inserts usually have a more massive backplate in order to avoid bending while de-molding. In addition to the higher thickness, inserts are being kept in place with a holding down clamp around its perimeter. Excellent thermal coupling is of great importance to achieve uniform molding behavior.
Material: EF-Nickel or Steel
Applications: Nano- and microoptics, microfluidics.
1. Convert customer data into Maskdesign
2. Fabrication of maskset
3. Lithography on substrates =» resist-master
4. Prepare the master for Ni-electroforming =» Nickel-master (pattern inverted / mirrored)
5. Removal of wafer and resist
6. Mechanical post-processing the geometry of the insert for mounting in the injection molding machine.
