AMBA has designed the first machine capable of producing two bolts at the same time.
Premiere at WIRE 2020: From the wire coil straight to 420-mm-long full-thread screws on a single machine
The new all-in-one screw making machine caters to trend in wood construction.
At WIRE 2022, Amba is going to introduce its new all-in-one machine for the production of 10-mm-diameter full-thread screws in lengths of up to 420 mm. It is the first machine in the world able to produce screws of this length and diameter from the coiled wire to the finished product in a continuous cycle. With a throughput of up to 80 screws per minute, it sets a new industry benchmark.
The new machine works according to the Amba-developed all-in-one principle, i.e. all process steps - from paying off, cutting to length and straightening of the wire to head forming and thread rolling - are performed on just one machine. And this at a rate of 80 pieces per minute.
There is a growing demand for full-thread screws of 420 mm length in wood construction, as a result of the current architectural trend of building wooden houses. While this has a long tradition in Scandinavian countries and the Alps, more and more wooden buildings are being constructed also in the northern parts of Germany.
With the new machine screw making shops can produce both full-thread and partially threaded screws at high cycle rates directly from the wire coil, meeting the growing requirements of the market.
Georg Haas, Head of Sales at Amba, explains the motivation behind the development of the new machine: “Our all-in-one machines achieve much higher throughputs than single-purpose machines that specialize in individual process steps, as rolling, for example. With the new machine, it is no longer necessary to feed, clamp, process and remove one item after the other. Instead, we have transferred discontinuous manufacturing into a quasi-continuous process. In certain applications this may result in a productivity rise by one order of magnitude.”
The first 420-mm screw making machine will be delivered shortly to a customer in Germany. Further orders for this new type of machine have already been booked.
