The Functionality of Dot Pin Marking Machine

Dot Pin Marking Machine also known as Dot Peen Marking Machine or Scribe Marking Machine performs long-lasting high-quality marking on a wide range of metal surfaces. This method involves a Dot Peen stylus marker that moves rapidly to mark a series of dots on the surface. The stylus moves in x and y directions on the surface, as programmed. It creates a series of dots to mark digits, unique data matrix codes and logos. The data matrix codes contain a lots of data.

Dot Pin Marking Machines work on many kinds of settings involving character styles, their sizes, and depths of an impression. Dot Pin Marking is the most common marking technology which is ideal for marking unique data codes for machine readability and identification. Dot marking ensures minimum possible stress on the material surface that’s getting marked. Dot Pin Marking Machines are ideal for all kinds of metal surfaces and even coated surfaces.

Factors Responsible for Quality Dot Pin Marking


Use of Fixtures

For a perfect marking process, it is important that the work piece is held firmly or else good quality marking cannot be possible. That’s where fixtures are used. A variety of fixtures are used by Dot Pin Marking Machines, for marking various kinds of surfaces. These fixtures are interchangeable and should be quickly changed using an efficient system for error-free marking.

Surface Texture

The texture of a material surface plays a very crucial role in setting the quality of mark. Smooth surfaced materials get better quality marks quiet easily while rough, rugged surfaces may get faulty or blurred marks. In fact, to make the mark readable or understandable by the machine correctly, it has to be dug far deeper on the unfinished or rough surface than on a smooth surface.

Type of Work Piece Surface

Quality of the mark scribed by a Dot Pin Marking Machine also depends upon the material surface. The flatter and uniform the surface, the better will be the mark quality. It depends upon the distance between the stylus or Dot Peen tip and the surface. If the distance is less, the mark won’t be deeper. There has to be a specific distance between the stylus marker and the surface to get the deeper mark.  

A Dot Pin Marking Machine on cylindrical surfaces requires several considerations like specified distance between the stylus and surface, character size, splitting the text for compensatory marking on variable gaps.

Angle of the Stylus Tip

The quality of mark also depends upon the angle at which the stylus presses the surface. Usually, the stylus angle is set to 90° but it may be changed as per requirement. The angle is changed, also to maintain the stylus life. The stylus life gets reduced with deeper marks. So it has to be set to maintain a balance between depth of the mark or mark quality and stylus life.

What is the Use of Laser Marking for Product Identification?

Product labelling plays a crucial role in identification of products. Labelling involves product marking which is done in various ways. With the passage of time, technologies have changed and provided with newest means in terms of marking products too. In early times, the product marking used to be done simply by ink stamping which would get blurred or vanish from the surface. With the advent of Dot Pin Marking machine, the problem of temporary markings got sorted. These machines have been serving as the most reliable source for product marking. The markings are permanent and pretty clear. Later, as technology advanced, Laser Marking Machines entered the market. Process of Marking: Being a step ahead of Dot Marking system, it puts permanent, high quality marks that can easily be read. It can make the markings of all font sizes on all kinds of surfaces like steel, brass, aluminium, copper, and even plastic. One thing that make laser marking machine the best is that while putting pe

Laser Marking is a step ahead of Dot Marking system as it offers high quality and readable markings on all the surface types. Laser Marking machines are used to engrave on all types of surfaces made of steel, aluminium, brass, copper, polymer or even plastic without laying stress on the surface. The markings can even be made on surfaces of any shape – be it a cable, wire or a plank or coil. The markings or engravings made by Laser Marking machines are permanent as they stay the same forever, allowing perfect and easy traceability of the product at any point in time. Source: Google Functions of a Laser Marking Machine Laser Marking Machines are used not only for engraving any surface, they are also used for Carbon migration. It is also used for Annealing purpose to strengthen the metal surface. Apart from this, a  Laser Marking Machine  also performs discoloration of the surface, especially of plastics. It can lighten or brighten the color of a surface. A color can even be r

Dot Pin Marking Machines - For High Quality & Precision Marking

Dot Pin Marking machines have always been the most reliable source of product marking system which ensures absolute precision and easy traceability of the product that is marked. Manufacturers, factory owners and even shop owners employ the machine for independent marking process. The best part about these machines is that they are easily programmable and can adjust automatically, according to the type of mark required. You don’t need to put the input. With smooth and fast and marking process, these machines save lot of time, money and effort for the user. The manufacturers become more productive. The accurate and error-free markings provided by Dot Pin Marking Machines help the user skip giving time and effort to tedious processes like reworking and testing. Dot Pin or Peen Marking machines put marks or dots by means of pins or peens. The series of dots in a particular pattern forms a number or letter. The machines mark the surface with due accuracy and without laying much pressure
