Pneumatic Dot Peen Marking Vs Electric Marking Machine

May 19, 2021

There are many types of marking machines, the most common used are pneumatic marking machines, electromagnetic marking machines, and laser marking machines.What are the difference between Pneumatic Marking Machine and electric Marking Machine?

 

What is a Electric Marking Machine?

 

The electromagnetic marking machine utilizes an electromagnetic coil to generate a magnetic field to drive the marking head to mark different depths on the working surface, thereby producing identification information.

 

Dot peen marking technology: A high-speed, cost-effective marking technology.All marks (text, numbers, LOGO, two-dimensional code, etc.) by dot peen marking are composed of a series of dot, and each dot is produced by the marking peen hitting the marking surface.

 

How does it Work

 

The controllable current pulse generates an impact force through the electromagnetic coil magnetic field. The marking head hits the surface of the material under the action of the magnetic field and marked point.Then, the high-performance spring brings the marking dot peen back to the initial position and waits for the next current pulse.

 

Main features:

  • Permanent marking
  • High cost-effective marking equipment;
  • No consumables;
  • High-speed, accurate marking (up to 5 characters/s);
  • Suitable for many materials;
  • Only require power supply, No air source.

 

Compared with pneumatic marking machine, electromagnetic marking machine saves air source and greatly reduces the noise during work, without splashing metal dust,fast speed, stability and high accuracy.

Electromagnetic marking machine can be widely used in automobile bodies, Sheet metal parts, nameplates and other occasions that require beautiful effects, no air source, and low-noise work are especially suitable for exquisite marking of high-end products such as aluminum, copper, electroplated parts, and anodized parts.

 

Main Equipment Parameter:

  • Speed: 10-120 characters/minute
  • Depth: 0.01-0.5 mm, the depth adjustable
  • Mark: graphics, characters, numbers, word width and size adjustable
  • Material: various metals (hardness below HRC60), various hard materials (PVC film, plastic, bakelite, etc.)
  • Graphic editing: automatic label storage, automatic serial number printing
  • Accuracy: accuracy error ≤0.001
  • Continuous working time: 24 hours/day
  • Average trouble-free: 15,000 hours
  • Marking range: 100mm×80mm, 150mm×80mm, or customized;

 

What is a Pneumatic Marking Machine

 

Pneumatic dot peen marking machine

Pneumatic marking machine is a device that dot peen by compressed air driving to print,which can print a certain depth of numbers, letters, vector diagrams and other marks on various parts,components and signs.

 

The pneumatic marking machine system consists of four parts:computer system,drive control system(electrical cabinet, control circuit board, driver), pneumatic system(gas circuit, filter pressure regulator, high frequency valve) and marking workbench(industrial-grade X-Y scanning system, Z-direction lifting system, marking head, work table).

 

How does it Work?

 

The dot peen controlled by computer moves on a certain trajectory on the X and Y two-dimensional surface. At the same time,It makes a high-frequency impact on the surface of the material under the action of compressed air, thereby printing a mark with a certain depth.

 

Main features:

  • Permanent marking
  • Greater depth
  • Controlled by a computer.
  • A variety of fonts graphics
  • Clear markings
  • High cost-effective marking equipment;
  • Suitable for marking all kinds of metal or non-metal signs, nameplates, flat arc surfaces of parts, and axial marking of cylindrical work-pieces.

 

Main Specifications:

  • Marking range: 110x80  (150×120/<200×160/(mm) or customized).
  • Material hardness: ≤HRA60
  • Marking depth: 0.1~1mm (depending on material hardness)
  • Marking speed: 30~50mm/s
  • Lifting range: 300-350mm (customizable)
  • Machine power: 350W
  • Air pressure requirement: 0.2~0.6Mpa (industrial air source or compressor air source)
  • Power requirements: 220V±10% 50HZ±1%

Pneumatic or Electric Machine,Which is Better?

 

Pneumatic or electric marking machine,which is better?A lot of customers are common confused these.In fact,pneumatic and electric marking machine both have their own advantages and disadvantages. First of all, the advantages of pneumatic marking machine is the deep marking than electric marking machine. Electric marking machine is more convenient to carry due to it does not require an air source, and is suitable for outdoor marking application.In short,the both marking machines can get good and clear marks in metal and no-metal material,and you can choose one according to yourself marking requirements.

 

Summary

 

The above are the comparative introduction of pneumatic and electric marking machines. Pneumatic marking machines and electric marking machines are mature products, and their working principles are basically similar. The marking depth of pneumatic marking machines is larger than electric ones,but electric marking is more fine,and the price of electric marking machine is higher than pneumatic.Therefore, each has its own advantages and disadvantages. We can choose one to increase our business according to actual require.
