'A shaped sheet or ring of rubber or other material sealing the junction between two surfaces in an engine or other device.'  
- Gasket, Oxford English Dictionary 
Metal gaskets are generally used in inhospitable environments, where other materials would lack durability. As chemical Etching provides burr and stress-free gaskets and seals any Etch Tech customer can feel secure in the longevity and durability of our product. 
The chemical milling / photo etching process produces burr-free, and stress-free, gaskets when cutting out the profile, unlike alternatives such as laser cutting. Etch Tech is able to produce a surface etch on the material, thereby creating a sealing groove, or platform, within the design / material of the gasket. Due to this, precision gaskets are an ideal component to be manufactured by Chemical Milling / Photo Etching Process. 
Etch Tech has a wealth of experience in the manufacture of high precision custom designed gaskets into the following sectors: 
Oil and Gas 
Process Industries 
Etch Tech can supply Photo Chemically Milled / Photo Etched metal Gaskets in the following materials: 
Stainless Steel

Design tolerances 
The Photo Etching process in place at Etch Tech Ltd is capable of etching extremely fine detail into metal. We have extensive experience working closely with customers to offer improved design tolerances on our Gaskets. Please contact our design engineers so discuss your requirements. 
For any volume of the production of Gaskets, the manufacturing technique of choice is Chemical Milling, see below for an in-depth view of the strengths of the process: 
Benefits of the Chemical Milling Process : 
Apertures on both sides as the etchant works on both sides of the metal 
Burr & Stress-free manufacturing method 
Custom parts – you design it – we make it! 
Cost-effective metal component prototyping 
Etch Tech can call on more than 30 years experience in the photo chemical etching of metal components
