With its internal screw production in the areas of punching and punch & bend technology, cold forming, plastic injection moulding and extrusion technology, the company is highly diversified and can therefore ensure quality control and optimal implementation of its customers’ stringent quality standards.
How are wooden construction screws manufactured at Eurotec?
To manufacture screws, the companies has its own cutting-edge machinery to enable all individual customer requirements to be met. The manufacturing of a screw always begins with selecting a suitable raw material. Cold heading wires with high carbon content are widely used, which can be hardened at a later stage. The cold heading wire is pre-drawn in a wire drawing shop and then fully drawn to the nominal size.
This is followed by the screw manufacture itself. The wound wire coils are fed into the machine with a decoiler. The wire is flattened by straightening units and cut to the appropriate lengths.
In the next step, the screw head and drive shapes are formed by double-blow presses. This involves pre-compression to create the volume, followed by final compression to form the geometry.
After this, a thread is rolled onto the surface by flat die rollers. For this procedure, a screw blank is pushed into a stationary thread rolling die and drawn by a moving thread rolling die. The thread reflects the negative impression of the rolling dies. Various types of thread can be produced using flat rollers or plain rollers. Plain rollers are used to manufacture fully threaded screws.
We have made it our mission to continuously optimise our tools in order to achieve the best possible results when our diverse screws are used, ensuring, for example, that screws can be driven in quickly and with reduced force, so that cordless screwdrivers need recharging less often and there is less cracking in the wooden construction material.
In the final stage, the manufactured screws are case-hardened to achieve both high surface hardness and a high breaking torque. The screws are then annealed. This procedure is necessary to homogenise the metal’s microstructure. This enables the screw to bend to a certain angle without breaking.
To protect the screws from corrosion, they are electrogalvanised. They are also given an anti-friction coating that is intended to further increase the corrosion protection and to make the screw easier to screw in.
Lastly, the wood construction screws are packaged appropriately and prepared for dispatch. They are now ready to be used for all kinds of wood construction projects.
