Are you considering adding a mechanical press to your manufacturing floor?
If so, then chances are you have an application in mind but you’ll need the nitty-gritty.
Mechanical presses are a great choice, but you should get the full information on uses and comparisons before you make the final commitment.
So, let’s hop in and help you determine if it’s the right choice for your needs.
What is a Mechanical Press?
A mechanical press uses a crankshaft and a motor to press two surfaces together. They’re capable of generating enough force to deform metal workpieces and press them into the desired shape.
Mechanical presses can produce a lot of force. Most produce somewhere between one and thirty tons of force on the workpiece.
Mechanical presses differ from pneumatic and hydraulic presses due to the mechanism which they use to create pressure. They generally have a fixed stroke length and a set pressure at the bottom of their action, which makes them a very reliable machine when it comes to forming metals.
How Does a Mechanical Press Compare to a Hydraulic Press?
Hydraulic presses are another common option found in manufacturing plants all over the world. They put down even more pressure and are also an excellent option for some uses.
Hydraulic presses operate well and with variable pressures which makes them versatile. They also offer more pressure for the same size of the machine since they use a hydraulic system to produce the pressures required.
They fall short in a couple of areas compared to mechanical presses, however.
Mechanical presses are able to go through the whole stamping process much more quickly. They’re often much better for quick production of parts due to this.
Mechanical presses also produce a more consistent stroke, stamping things down at almost exactly the same pressure within a smaller amount of time.
The hydraulic press is often used for deeper parts, however, and there are some advantages to using a slower stroke depending on the end result desired from the workpiece.
Hydraulic presses also find more frequent applications outside of metalworking. Making pills or pressing cosmetics are often done with a hydraulic press since they require less workspace on the floor. It’s a big advantage in manufacturing situations where floor space is needed for other processes.
What Are Mechanical Presses Used For?
Mechanical presses are almost always used for metal-forming applications. Their pressure, speed, and consistency allow them to quickly and uniformly create parts.
These days they’re primarily used in places where the speed of production is a major concern. Hydraulic presses are often considered safer due to their much lower speed of production but either can be used by a skilled operator without much risk.
Die stamping is one of the major applications that mechanical presses are used for. In this process, a die is placed on the press along with the workpiece and the pressure deforms the metal into the desired end-shape.
Some presses have more specialized applications.
Forging presses, for instance, heat up the workpiece before pressing down. They’re often used for harder alloys that would require more force than a standard mechanical press can produce at room temperature.
Their larger size also lends them well to form larger parts.
In general, they’re an excellent manufacturing tool for the majority of parts made from sheet metal. They’re limited more by the operator’s skill and their intended application than the tool itself.
Is a Mechanical Press Ideal for My Manufacturing Floor?
If you’re running a shop that specializes in metal parts in large quantities then a mechanical press is likely to be one of the best purchases you’ve made.
A straight-side press and the proper dies, along with a skilled machinist, is the quickest and easiest way to stamp parts. The real limitation for most floors is the size of the press, as long as you have the room they’re a great option.
They’re also more energy-efficient than hydraulic presses. If energy costs in your area are higher than the national average they may end up being the better overall option in the majority of cases.
You should keep in mind that the stroke of a mechanical press is always going to be shorter than a hydraulic press of the same size as well.
Of course, the most important thing is to make sure that you’re able to find a good spot on the floor for a mechanical press. They’re rather large machines when compared to other options so have a spot in mind before making the purchase.
Finding a Good Deal on a Mechanical Press
Mechanical presses are a significant investment in your manufacturing capabilities. Finding the right price can make a huge difference in what you eventually decide to do.
While a new press is always going to be the best option it’s also going to be the most expensive. Depending on what you’re looking for you may not even be able to find exactly what you need at the time either.
Instead, many people look to the secondhand market.
That said, buying from a private seller always entails some risk. Instead, if you’re looking for a great deal your best option is to use a reputable specialist company that offers rebuilt and certified second-hand presses.
