Plasma and oxyfuel are known to be a productive combination. They have remained to be industry workhorses. Overtime, plasma and oxyfuel machines have become simpler and easier to use. They also require less operator intervention. Both oxyfuel and plasma have advanced in the past decade. Having both plasma and oxyfuel on the same machine allows the shop to take advantage of the strengths of each process. The shop achieves the required part accuracy at a far lower cost than if it used the high-accuracy plasma process to cut the entire part.
Using both mechanized oxyfuel and plasma cutting can make plate fabrication far more efficient and flexible. As these technologies advance, fabricators can produce their parts smarter, faster, with the highest quality, and at lower cost. Regardless, the choice to use these technologies on separate machines or on one system is as individual as the application requirements.
Automation Alternatives recently introduced a fiber laser welding system called RubyLaser that is perfect for joining dissimilar materials. Its spot size is as small as 0.001 to 0.002 in. and fast weld speeds allow the system to deliver high power density. These characteristics make it perfect for welding together materials that are not identical.
Typical materials include stainless steel, titanium, aluminum, nitinol and more.
Don’t worry, you won’t be eating these 3-D printed apples; rather, they are used to monitor the conditions in which your apples travel from farm to store.
These apples are specifically engineered to match the thermal response of real apples, meaning they will cool at a rate that is within 5% of real apples, compared to the 16% of water-filled fruit simulators. They can be placed among the real apples as they travel from cold stores to ripening facilities to stores.
Ultimately, the novel sensor system provides an improved method to identify any quality issues when transporting fruits. Creators hope to better pinpoint the location and reason for unexpected quality loss.
Manufacturing Engineeringtalked to leaders at five companies to get their input on the future of manufacturing. We pulled our top three points for you to enjoy!
“The growth of Industry 4.0, or the Internet of Things (IoT), is a key trend and willhave a profound influence on tooling and workholding…” Jack Burley, vice president of sales and engineering, BIG Kaiser Precision Tooling, Inc.
“The companies that have prepared themselves and haveadopted highly productive machining practices will benefit the most over the next five years, regardless of the parts of the world in which they manufacture their products or do business.” Brendt Holden, president, Haimer USA, LLC.
“The industry will also realize huge benefits through investment in automation as well as on the redistribution of human resources from the traditional machine operator to skilled programmers, cell designers, robotic experts and database management personnel.” Bill Obras, vice president of sales and marketing, Rego-Fix Tool Corp.
Now that we’ve learned all about plasma, it’s time to learn how the fourth state of matter cuts through metal like butter.
First, a pressurized gas is sent through a small channel with a negatively charged electrode. When the power is turned on, and the tip of the nozzle touches metal, a circuit is formed and a powerful spark is generated. This spark heats the gas until it becomes plasma, moving at 20,000 feet per second, which melts metal to molten slag.

One of the flame cutting services we offer at Sullivan Precision Plate is High Definition Plasma. Over the next few weeks, we’re going to dive into the complex process of plasma cutting (with the help of our friends from How Stuff Works).
This week, we’re going to take a quick chemistry lesson. Most of us know the three states of matter: solid, liquid and gas. Many of us forget, however, the fourth state of matter: plasma. Plasma is what happens when you heat a gas to an extremely high temperature.
The energy begins to break apart the gas molecules, and the atoms begin to split. Normal atoms are made up of protons and neutrons in the nucleus surrounded by a cloud of electrons. In plasma, the electrons separate from the nucleus and begin to move around quickly, leaving behind their positively charged nuclei. These positively charged nuclei are known as ions. When the fast-moving electrons collide with other electrons and ions, they release vast amounts of energy. This energy is what gives plasma its unique status and unbelievable cutting power.
