The new generation of work tables for setters and engravers “Flexbo 4.0”, which are ergonomically designed, have been proven to improve working conditions and efficiency in the setting and engraving handcraft. They have been further developed in close cooperation with setters and engravers and are characterized by their ergonomics in several respects: all workbenches are electrically height-adjustable as standard and impress with many well thought-out, ergonomic detail solutions.

The new workbenches are available in two versions: as workbenches with pull-out board or as workbenches with work bowl.

The setters‘ benches with pull-out board are extremely stable so that you can carry out all types of jewellery work onengraving blocks on the individually adjustable and lockable pull-out board without jolting. The filing drawer underneath is
used either to collect filing residues or as a tool drawer for storing files, hand gravers, etc.

On the setters‘ benches with work recess, the setter works in a recess set into the worktable, in which he can place his engraving block and a the setter’s microscope ‘floating’ above it. This variant allows the setter to work conventionally on the worktable top and not on a pull-out board underneath. It is particularly favoured in classic jewellery-making countries such as Italy.

Who hasn't had a disappointed customer who has returned to your shop with a defective 8ct or 9ct piece of jewellery shortly after purchase or repair? In some cases, the jewellery parts have completely crumbled or the newly attached clasp has disintegrated into several components?

The most common cause of this physical destruction is stress corrosion cracking. This phenomenon occurs when cracks form in materials under the influence of stresses and corrosive media.

Stress corrosion cracking is characterised by the fact that deformed alloys crack under the influence of certain chemicals without any apparent external influence. The main triggering influences are stress states, alloy composition and chemicals.

Low-carat alloys below a fineness of 585/- are particularly susceptible to stress corrosion cracking. For example, 8ct or 9ct often contains high levels of additives such as zinc. Such jewellery / findings / wires can be damaged even after a short period of wear, especially if they come into contact with corrosive substances such as ammonia, ammonium salts or sulphur dioxide.
