Sheet metal manufacturing has come a long way, thanks to automation practices.
Automation refers to technology that reduces the need for human labor. One might hear the definition of automation and assume that these practices didn't begin to evolve until the 19th and 20th centuries.
What's surprising is that sheet metal automation can be traced back to the late 15th century. In 1485, Leonardo da Vinci was recorded as having sketched a rolling mill that was seen as quite advanced.
It didn't take long for prototype rolling mills to emerge as two reports of rolling mills surfaced in the early 1500s. One rolling mill was designed to obtain gold sheets with identical thickness to draw coins, while the other rolling mill was used to cut metal sheets into smaller strips.
Leonardo da Vinci's vision was realized in 1590 when a mill that used two heavy cylinders to alter metal's thickness was introduced.
Fast forward to modern times, and the sheet metal manufacturing has grown exponentially due to automation with an estimated value of around $20.5 billion in 2011.
So, what happened in between Leonardo Da Vinci's drawing and now to create such a booming industry?
Let's dive in:
What's The Evolution of Automation in Metal Manufacturing?
Most progress toward success begins in failure through trial and error.
The story of sheet metal automation is no different.
Around 1606, the puddling technique was invented. Puddling involves converting cast iron into steel through high heat exposure and stirring the material in a reverb furnace with oxidizing substances.
Through puddling, workers aimed to formulate a process that successfully converted cast iron into steel and removed some of the material's impurities such as carbon. Unfortunately, the puddling process was incredibly inconsistent in its ability to produce results due to insufficient power levels from the furnace.
It wasn't until the Industrial Revolution that sheet metal automation began to make serious progress.
1760: The Industrial Revolution
The industrial revolution fostered a boom in sheet metal production.
Sheet metal manufacturers were able to produce higher quality products at an accelerated rate thanks to the advent of press brakes and assembly lines. Momentum kept building after 1760 as Joseph Bramah developed the hydraulic press in 1770, and Jean Pierre Droz streamlined the sheet metal process.
Up until and around the end of the Industrial Revolution in 1840, significant sheet metal developments consisted of:
- Introducing the steam hammer (1801)
- The Bessemer converter arises as a cheaper alternative to traditional steel production from cast iron (1857)
- Merging of unions in Europe (1861)
After taking significant strides during the 18th and 19th centuries, steel manufacturing was ready to make its mark on the 20th century.
20th Century Steel Manufacturing and Modern Times
Unions are a driving force of sheet metal production. In 1969, the National Union of Sheet Metal Workers, Coppersmiths, Heating, and Domestic engineers was formed to help these workers establish proper representation.
Inventions such as the Basic Oxygen Furnace in 1967 and the introduction of air bending techniques in 1970 served to expand sheet metal manufacturing.
The last major union shift occurred in 1983 when the National Union of Sheet Metal Workers, Coppersmiths, Heating, and Domestic Engineers shifted into a trade union known as the Technical, Administrative, and Supervisory Section.
From this brief rundown of sheet metal manufacturing history, we can conclude that the evolution from a simple Leonardo da Vinci sketch to a multi-billion dollar industry is thanks to improved strategies, tools, and streamlined projects.
So, what's the current state of automation in sheet metal manufacturing?
What's The Current State of Automation in Metal Manufacturing?
TRUMPF is a prime example of a company leading the way to evolve sheet metal manufacturing.
Years after becoming a company in 1923, TRUMPF is one of the world's leading providers of machine tools for flexible sheet metal processing.
Here are some of the essential duties that TRUMPF machines perform for sheet metal manufacturers:
- Welding applications
- Laser cutting
- Punch and laser processing
Smaller manufacturers can benefit greatly from technology, such as Trumpf's bending machines. Automation is critical in sheet metal bending as manufacturers won't have to convert a bending machine every single time they adjust the program. The result is a reduction in time and labor.
In 2015, Trumpf made a big leap and made 3D printing machinery for metal components available. A sign of success for Trumpf is that their sales and employee numbers continue to grow.
How Else Does Trumpf Help Evolve Sheet Metal Manufacturing?
Trump's automation page helps inform their audience of its mission when it comes to streamlining automation.
Essential tasks for Trumpf automation include:
