With the advent of fast-paced manufacturing lines and consumer demands, it is not only necessary to produce good quality products but also to make sure that the product doesn’t wallow in the market. Every product that you manufacture must have an identity or more importantly identification.
This helps companies in refining their quality systems and managing their production numbers as well. Apart from that, some information is critical for consumers. Hence the product must be displaying all the required information.
While having all of these points in mind, it is really necessary that everyone must know about dot pin marking machines.
Dot peen marking machines or more commonly known as dot pin marking machines are one of the greatest marking technologies out there. It has solved the problem of displaying information specifically on the king of industry i.e. metal.
Dot pin marking machines can mark or engrave every bit of detail, be it serial numbers, barcodes, batch numbers, logos, customer-related information, machine parameters or specifications, or anything. You name it and dot pin marking machines can engrave that on the metals.
What is a dot pin marking machine and how does it work?
dot pin marking machine or dot pin stamping machine is a kind of stamping machine that works electromechanically in a to and fro motion of the stylus. The stylus is actually the tool that vibrates to and fro and creates indentations on the product.
It is made up of carbide or diamond. Since diamond and carbide styluses are very hard when it comes to strength, they work efficiently for stamping needs.
The vibratory motion of the stylus creates dots on the substrate part. One vibration creates one dot. Extrapolate this vibratory motion over time and you get a series of closely spaced dots that look almost like a continuous line.
The space between the dots or the dots per inch is called the resolution of the marking machine. If the resolution value is less then it means that the dots are closely spaced. The closely spaced dots give a great finishing look thus making your product look more professional and top-notch.
Dot peen engraving machines work by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked. The result is a succession of dots to create digits, text, logos, and 2D data matrix codes.
Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse.
Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
Applications of Dot Pin Stamping Machines
Dot Pin stamping machines have a variety of applications in the manufacturing industry because of compatibility with so many materials. The materials that allow dot pin marking are as follows:
- Metals like iron, steel, aluminum, and brass
- Wood
- Plastics
- Cardboard
Metals are undoubtedly the most favored type of material that allows steel stamps by dot pin marking machines. Having said that, the scope of dot pin marking machines is somewhat beyond metals, too.
These industrial marvel machines create stamping on wood and plastics as well. If your business involves wood and plastics, you’ve landed yourself on the best product out there for marking.
However, other sectors/parts which benefit from dot pin marking machines are listed as follows:
- Medical equipment
- Military equipment
- Electrical components and machines
- Heavy mechanical complexes
- Aeronautical and aerospace complexes
- Electronics
We all know by now that the medical field has also some rules and regulations to follow when it comes to equipment identification and asset management. Without making any wrong guesses, we all know that dot pin marking machines come in handy for such needs.
From medical to military equipment, dot pin has ensured its presence everywhere. That’s how useful this technology is.
Types of Dot Pin Marking Machines
If we talk about functionality only, there are two types of dot pin marking machines:
- Pneumatic Dot Pin Marking Machines
- Electric Dot Pin Marking Machines
Let’s talk about these two types in detail, shall we?
Pneumatic Dot Pin Marking Machines
As the name suggests, these dot pin marking machines use compressed air for their functioning. The compressed air is used to drive the stylus of the machine. One advantage of pneumatic systems over electric systems is that the air produces more force in comparison with electric machines.
The impact is more powerful which makes it possible for dot pin markers to engrave on steels with hardness up to 65 HRC. The air pressure needs adjustment according to the type of material that requires engraving.
The speed can be varied with the stylus reaching up to 80 to 100 vibrations per second. This high speed is responsible for a smoother finish and good resolution of the marks. Due to high-speed functioning, this type of dot pin copes with the fast production lines easily.
HS DP 01
If we talk about basics, then Heatsign has the best pneumatic dot pin marking machines out there. The HS-DP01 dot pin engraver is a column-mounted or stand-alone machine.
It allows easy clamping of the objects which need engraving. Since this is a column-mounted structure, it excels in engraving flat shapes. This pneumatic machine is capable of engraving steel with hardness ranging up to 60 HRC.
Most commonly, HS DP-01 is used to engrave on nameplates of vehicles. If you have a similar part maker, then try giving this machine a try. You will not forget the experience.
The marking area of this machine is 120x80mm which is very decent. The depth created by the stylus of HS DP01 is in the range of 0.01-0.5mm and the speed that can be achieved with this depth is 30-40 millimeters per second. But this data is objective since it varies depending upon the material to be engraved.
Electric Dot Pin Marking Machines
If you don’t have access to compressed air, you don’t have to stop right there. Stamping is important, right? We have a great solution for your stamping needs in case of the absence of compressed air; the electric-powered dot pin marking machines.
The electric dot pin machines cover all the limitations of the pneumatic dot pin machines. Dot pin machines may be faster but they are not precise. Electric dot pin engraving machines are precise in their operation and that too while offering higher speeds.
The electric dot pin marking machines don’t have that much impact force on the substrate hence they can easily engrave on plastics and wood. For companies looking to engrave complex shapes like logos or matrix codes in 2d, these electric dot pin machines come in handy.
e10R i53
The i53 of the e10R series by SIC finds its applications precisely in automatic production lines. It’s their easiest machine to integrate with any kind of system. Although the marking area is small it can easily engrave serial numbers, barcodes, or alphanumeric information on your product.
This mini magic machine has a sleek design with an almost negligible need for maintenance. The consumables are also negligible. With a 50mm carbide stylus and 50x20mm marking window, this machine can engrave steels with hardness up to 62 HRC. Mind-blowing, right?
This machine doesn’t require a separate pneumatic system. It is an electromagnetic dot pin engraving machine that can engrave on any kind of shape be it a circle, a flange, a curve, or anything.
The precise and accurate output, the decent distance between the stylus and the product, speedy integrated software, and carbide tool makes this machine super awesome and sturdy.
Classification based on usage Details
Depending upon the usage of the dot pin stamping machines, they are roughly categorized into three different classes namely, handheld dot pin markers, Integrated dot pin markers, and column-mounted or station mounted dot pin stampers.
Integrated Dot Pin Marking Machines
When production lines are consistent and fast, the identification process needs to be fully automated that can cope with the production’s pace. For such purposes, integrated dot pin machines are available in the market.
These automatic machines are directly integrated into the system either with the help of their built-in software or by using any compatible software from windows or mac. This way, the machine knows what to do, when to do and how to do it.
No need to manually setting up the machine for every part on the assembly line. The integrated machines need to have a compact and slim design that is easy to fit along with other machinery on the line.
They must be robust in their long-term working because production might go on for hours and days without taking any considerable break and lastly, the speeds of these integrated dot pin markers must be high enough so that they can be varied as per the demand of the assembly line’s speed.
It’s an incredible way of getting your marking needs fulfilled. Just feed in your data and leave the rest on your machine. These markers will do your work for you. There are many well-known names in the industry that manufacture dot pin markers. SIC, Heatsign, and Automator are a few big names.
Column Mounted Dot Pin Markers
Column mounted dot pin markers are those markers that are individual workstations. These machines come preloaded with a separate controller for adjustments. These machines operate as individual and separate machines running parallel to the production lines. The life of these machines is also long enough to make them sustain for years.
These workstations run on high power that makes them very accurate in their alignment and their output results. The marking windows vary depending upon the machine. It can either be big or small as per the demand of the user.
These machines are versatile in their function and the workpieces don’t have to be of exact same shapes and sizes.
Handheld Dot Pin Engraving Machines
Handheld dot pin engravers are portable machines that find their best use in situations where the product needs engraving apart from the main production line. Whenever you have to separately mark something on your product, you can’t just bring your integrated marker or the column-mounted marker to the place where the product is placed.
You always got to have a portable solution to such situations and this is where handheld dot pin markers come into play. Handheld dot pin engravers offer assistance in your marking needs by being portable and versatile.
Their marking areas are also the same as that of other machines. Handheld markers are mostly electric markers since you can’t carry air compressors everywhere. Due to electricity as a power source, their output is very accurate if you have the required training for the alignment of the machine with the part.
HS PE 01/02
With an integrated touchscreen display, these electric-powered handheld dot pin markers are very handy. Since they are portable, they are very light in weight. Heastsign has used a high-quality stepper motor in its construction that makes it a good engraver for metals.
The operation of the machine is very smooth and vibration-free. The pin used in these portable machines consists of tungsten alloys which can give you a year of engraving services. The marking area is really good i.e. 140x60mm.
In case of a power outage, Heatsign also can offer these portable beasts with standby batteries that can be used upon configuration. These machines can engrave alphabets, numbers, logos, matrix codes in two dimensions.
