As the coffee industry has grown in recent years, the market for home espresso machines has grown dramatically. Several coffee-loving entrepreneurs have designed new machines for this market. If you're trying to create a new home espresso machine, use cold rolled steel for your machine's metal parts. It will make your model attractive, affordable and easy to assemble.
Cold Rolled Steel Provides a Shiny Finish
Cold rolled steel will give your espresso machine a shiny, polished look, making it stand out on store shelves and in people's kitchens. After annealing, cold rolled steel goes through temper rolling, which is where this type of steel gets its name. Temper rolling is the process of running the sheet of steel through tempers, which roll over the metal's surface. In this step, any number of finishes can be applied to the steel, including a polished one that will make your home espresso machine shine.
In contrast, hot rolled steel does not go through temper rolling, so it doesn't have shiny finish. Hot rolled steel instead has a rough finish.
By using cold rolled steel to give the exterior of your espresso machine a shiny finish, your design will mimic many commercial espresso machines. Coffee drinkers are used to seeing polished machines made from stainless steel in cafes, and they'll appreciate being able to replicate the look of a commercial machine in their home.
Stainless steel is also easy for home baristas making lattes and cappuccinos to clean spilled milk off of. As long as milk is wiped off soon after being spilled, it'll wipe off easily.
Cold Rolled Steel is Affordable
Cold rolled steel usually costs more than hot rolled steel because it's more expensive to process. Cold rolled steel must be cooled, rolled and reheated, whereas hot rolled does not need to be cooled and then reheated -- it is rolled while still hot.
Because espresso machines are small appliances, however, you won't notice a significant difference in cost between cold and hot rolled steel. At the time of writing, according to MetalPrices.com, hot rolled steel was selling for a $0.19 to $0.20 per pound, and cold rolled steel was selling for between $0.25 and $0.28 per pound. Even if you used 10 pounds of steel in your machine, which would make it extremely heavy, the difference in cost would be, at most, $0.90 per unit.
Cold Rolled Steel is Easy to Work With
Even if you don't increase your selling price by $0.90, you'll more than make up the increased cost of cold rolled steel during assembly.
Hot rolled steel is often shipped to customers in oversized pieces for two reasons. First, it's difficult for steel manufacturers to precisely control the final dimensions of a piece of hot rolled steel. Because the steel is rolled when hot, it may change shape slightly when it cools. Second, hot rolled steel is somewhat pliable, so customers often cut it as needed on site.
Cold rolled steel is made to exacting specifications when manufactured. Unlike hot rolled steel, cold rolled steel doesn't cool after rolling, so it's possible to precisely control its final dimensions. Also, it's more difficult to cut than hot rolled steel, so it's usually not adjusted by customers.
By using custom-made pieces of cold rolled steel, you'll be able to quickly assemble units of your home espresso machine. You won't have to waste time cutting them to size before you put them on your machine. As soon as you have them, you can secure them together.
The potential time savings are significant, because there are many different pieces that must be fit together. In addition to the four sides of the machine, the group head, which is where the espresso comes out of, the steam wand, and the tray below the group head and steam wand can all be easily attached to the appropriate components during assembly.
If you have a unique design for a home espresso machine that you'd like to bring to market, contact a company that offers custom pieces of cold rolled steel. Using this metal in your machine will let you make a home espresso machine that's beautiful, inexpensive and can be built quickly.
