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.

The problem of testing gold jewellery

Authenticating gold jewellery is a major challenge. Due to the very diverse geometries (rings, necklaces and ear studs, etc.) and the composition (different mixed gold alloys in different carats), it is impossible to determine gold jewellery exactly using only one test method. The most common types of counterfeit jewellery are

• Counterfeit jewellery with base metals: This refers to the plating of a base metal with gold. This often occurs with rings or chains made of tungsten or tungsten carbide, whereby these materials almost perfectly imitate the density and thus the “heavy feeling” and feel of real gold jewellery.
• Under-alloying / hallmark fraud: If the gold content of an alloy is lower than specified by the hallmark.
• This can also be done in an even more sophisticated way, in that the surface of the piece of jewellery has the correct alloy and the underlying material is worthless foreign material or an inferior alloy.

Due to the large number of different types of gold alloys and jewellery geometries, the testing of jewellery is more demanding than that of gold bars, for example. The following testing methods should therefore be available when purchasing jewellery.

1. magnetic scale "MagneticScreenScale "
A sustainable method for measuring bars and coins is to determine the so-called magnetic susceptibility properties. This makes it possible to determine, even through blister packs and packaging up to a certain thickness, whether the material applied has the correct magnetic behaviour - para- or diamagnetic, i.e. attractive or repulsive. A so-called “tungsten detector” can be used to determine the presence of a potential foreign body: a gold bar as a so-called diamagnet displaces a magnetic field, creating pressure on the measuring head of the scale and displaying a positive value. If a supposedly genuine fine gold bar is placed on the scale and a negative value appears, it is in most cases a fake.

2. density scale "DensityScreenScale "
You can use the density scales to quickly and precisely determine the density of all types of materials. It is equally suitable for analysing bars and gold jewellery to determine their purity and alloy composition and to determine bars or jewellery that have been “stretched” or under-alloyed with silver or copper. The density is determined using the tried and tested method of Archimedes: To do this, the object is weighed with a sieve under water and once “normally”. The density can be determined directly from the two different values. This gives you an insight into the quality and carat of the gold or even an initial indication of the possible presence of forgeries. Determining the authenticity and gold content of geometrically irregular objects such as jewellery is therefore no problem.

3. surface testing with test acids or X-ray fluorescence analysis

• The gold coating sample with test acids: In principle, the first, relatively simple and cost-effective step is to determine the gold content using gold test acids.
• X-ray fluorescence analysis (XRF): This determines the exact elemental composition of the jewellery on the surface. This method is very expensive (approx. 15,000 - 45,000 EUR) and is purely superficial: the maximum penetration depth is only 0.010 mm.

Electrochemical testing using the "CaratScreenPen ".
The CaratScreenPen uses an electrochemical process to determine the purity and fine gold content on the surface of gold and platinum jewellery. The measuring tip forms a so-called “galvanic cell” on contact with the object lying on the measuring surface. This results in a certain electrochemical behaviour, which is registered by the measuring tip and processed by the device.

The complete and detailed article on the methods of gold testing can be found here:

in a minimalist design and high elegance. The Doubleclip is safe to use and immediately impresses with its quick and easy opening and closing. The innovative double locking mechanism keeps the chain reliably together at all times and gives the wearer peace of mind.

An acoustic “click” confirmation gives the user a feeling of security. The locking parts are movable and prevent the chain from twisting.

The clasp can be attached to almost any type of chain.

Manufacturing techniques for watch straps

What does cut strap actually mean and what are the differences to a fully remborded or semi-remborded leather strap?

What characterises a leather strap “Made in Gemany” and how many work steps are required for this?

Cut strap (approx. 70 work steps)

The cut strap is the most common, but rather simple leather strap. It consists of a three-layer material - upper leather, filling material and lining leather. The leather is cut by using a cutting tool and the edges are then varnished.

With around 70 work steps, it is somewhat more complex to produce than the semi-remborded leather strap.

Semi-remborded or semi-crowned leather strap (approx. 50 work steps)

With the semi-remborded strap, the upper leather surrounds the body of the strap and the lining leather forms the end at the bottom. In contrast to the full remborded strap, the upper leather is not covered and sewn under the lining leather. It is therefore not the seam that holds the strap together but, as with the cut strap, only the adhesive. Due to the durability is this the optimal production method as it shows no open edges.

This production method could only be implemented with modern, environmentally friendly adhesives and the only approximately 50 work steps have lead to economical consumer prices.

Remborded or full wraparound finish leather strap (approx. 100-120 work steps)

With the full remborded leather strap, the upper leather is wrapped around the filling material and sealed from the lining leather by adhesion. On the inside of the leather strap is a breathable filling material which leads to a better ventilation effect (“aero lining”). All the layers are glued with each other. A thread is only a design feature. Semi- and fully remborded leather straps combine softness - depending on the upper leather - with high stability and durability.

With approx. 100-120 work steps, it is quite complex to produce, which is why it is preferably used for high-quality bracelets.
