Nickel shims / nickel molds

Nickel shims are made for nanoimprint lithography and replication and we have long experience with production of them (often called nickel shims or nickel sleeves). 

We happen to be experts in custom specified structures.

Nickel shims and how we can help

Nickel shims are always made from an existing pattern, which typically is a silicon
or fused silica master. From the master, we can create a corresponding nickel mold with the same polarity or the opposite polarity of the master. Since we make the nickel molds based on a silicon or fused silica master, we can offer nickel molds with the same structures as we can offer on silicon or fused silica.

Examples are:

Nickel shim

Use of nickel molds/shims

Nickel molds/nickel shims can be used for a wide range of replication processes. For example:

One of the advantages of nickel molds is that it can be bent and shaped, unlike silicon or fused silica. This allows nickel molds/shims to be fixed onto rollers for high-throughput processes.

Typical applications are microfluidic devices, surface functionalization and engineering, microlens arraysdiffusers, diffraction grating etc.
