PRECISION STRIP FOR ETCHING AND LASER CUTTING

Precision strip, used to produce etched and/or laser cut components must fulfill a variety of conflicting properties. In cooperation with leading industrial partners, Zapp has developed steel grades to meet the most challenging demands for material processibility as well as final product precision and performance. These demanding requirements can only be met by defining accurate processes from the liquid steel until the final delivery to the customer. For over a century Zapp has worked with stainless steel developers to define the highest precision for its customers.

 

Important material properties

There are numerous factors, which need to be carefully controlled during the production of our etching grade strip, to ensure that our customers can process the material as efficiently and precisely as possible. The main properties that require careful consideration are listed in the table below:

Steel strip properties Photo chemical processing
Chemical composition Etching speed
Microstructure Etching speed resolution
Shape Resolution/ease of processing
Surface roughness Adhesion of photoresist
Surface cleanness Uniformity of processing
Avoidance of surface defects Etching defects
Residual stress Dimensional stability

APPLICATIONS

Zapp’s precision strip is used for the most demanding etching and laser cut applications such as:

  • Stencil masks
  • Fine metal masks
  • Fine mesh filters
  • Flexible circuit boards
  • Complex electrical components
  • Intricate watch components
  • Medical components
  • High quality decorative parts

Material för Etsning

Zapp’s etching grade products Zapp Super-Etch and Zapp Micro-Etch are used by many leading etching companies, to produce high-end parts for global supply chains.

Zapp’s portfolio of steel grades contains customized chemistries for each standard. Long established relationships with leading global suppliers have enabled them to co-develop a number of propriety Zapp steel grades with tightly restricted chemistries. This ensures that we can select the perfect material to meet your requirements, thereby ensuring reproducible processing and a low scatter of final product properties. As an example we carry five Zapp versions within the standard 1.4310 (301) family, each with a specific chemical nuance for optimized performance.
