Aachener Maschinenbau GmbH (Amba) has further enhanced its proven All-in-One machines for long-screw production: The machines are now able to produce up to 420-mm-long full-thread screws of 10 mm outside diameter.
80 full-thread screws of up to 420 mm length produced on a single machine in one minute
New All-in-One machine produces full-thread screws in one continuous cycle directly from the coil.
Aachener Maschinenbau GmbH (Amba) has further enhanced its proven All-in-One machines for long-screw production: The machines are now able to produce up to 420-mm-long full-thread screws of 10 mm outside diameter. The first new-generation machines are already in operation at various screw manufacturers, where they produce almost 5,000 wood construction screws per hour.
The new Amba All-in-One machines are the first in the world able to produce screws of this exceptional length and diameter in a single cycle. They operate continuously, directly from the coil. Therefore, it is no longer necessary to feed, clamp, process and remove one item after the other. In this way, the machines achieve throughput rates of up to 80 full-thread screws per minute, raising the bar in the screw-making industry to a new performance level. The more powerful and, at the same time, highly energy-efficient drive forms the core of this latest machine generation. It is more compact, more economical and more robust than the predecessor design and can be retrofitted to earlier-generation machines.
“In the new drive, we have reduced the flywheel mass to just one third of what it was before. This considerably reduces the machine’s energy consumption. Nevertheless, with the upstream planetary gear, the machines achieve much higher speeds and torques than the previous-generation machines. Moreover, setting the machines up has also become easier and faster,” says Georg Haas, Manager Sales at Amba.
The development of the new machines was driven by the continuously rising demand for extra long, high-performance screws in the wood construction industry. Georg Haas continues: “Our new All-in-One screw making machines caters to this trend. Wooden homes have become increasingly popular. In 2021, wooden houses for the first time exceeded the 20 percent share of all houses built. This trend is likely to continue for two main reasons: growing environmental awareness and the fact that wooden homes are faster to build, while providing the same long-term value and being just as durable as a brick house.”
The modular design of the new machines provides screw manufacturers maximum flexibility. For example, they can produce both full-thread and partial-thread screws at high cycle rates in different lengths and diameters.
The first machines able to produce 420-mm-long full-thread screw have been delivered and are already successfully in operation at several screwmaking facilities.

Aachener Maschinenbau GmbH – generally referred to as “Amba” – was founded in 1908, at a time when Aachen was worldwide famous for its high-quality needle production. Since then, the company has evolved into an internationally renowned manufacturer of machinery used to make cold-formed metal components.
Today, Amba specializes in equipment for the production of long and slender components with varying cross-sections, such as screws between 60 and 2,500 mm long, and tubes and spokes.
The Amba All-in-One design has made the company the world’s only supplier of machinery that can perform all steps needed to manufacture long and complex components continuously on just one machine. All process steps from feeding the input stock – wire rod or tube blanks – up to the finished, packaged product are handled by just one machine. This is unique in the industry.
At its headquarters in Alsdorf near Aachen, Amba employs 80 people in its development and design departments, in the workshops and in after-sales.

Contact for the press:
With effect from 1 January 2022, Georg Haas is the new Manager Sales at Aachener Maschinenbau GmbH (Amba), succeeding Manfred Houben.
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.
Amba has enhanced the functionality of its All-in-One screw and bolt making machines. New machining options provide even higher throughput rates and more flexibility in the screw making shop. The new-generation machines can produce screws with a milled-in notch along their tip at rates of up to 80 pieces per minute.
AMBA’s new gauge reducing machines achieve throughputs of up to 40 pieces per minute in spoke blank production – many times over the rates achievable by conventional machines.
