Metals Processing

In the column to the right you will find useful information about the processing of metals.

Below you will find recent posts on the 4M Association which are considered to be of interest to the Metals Interest Group.

Electro Chemical Machining

Technology suitable small quantity production

Electro Chemical Machining (ECM) is a method of working extremely hard materials or materials that are difficult to machine cleanly using conventional methods. It is limited, however, to electrically conductive materials.

LIGA

Technology suitable for small quantity production

The LIGA technology comprises the processes of X-ray lithography, electroforming and moulding. The process combines photoetching and electrical plating. In the first step, a deep etching pattern is made in a photoresist after exposure to synchrotron radiation (SR) through a patterned mask. In the etched grooves, a metal is electrically plated.
