Dot peen marking is an industrial marking method used to make permanent marks on metal, plastic and other hard surfaces. This system uses a needle or lug mechanism to apply small dots of impact to the surface. These dots come together to form markings such as text, numbers, logos or barcodes.
Advantages of Dot Matrix Marking
Permanent Marking: Resistant to abrasion, chemicals and high temperatures.
Low Cost: More cost-effective than laser or inkjet systems.
Compatible with Various Materials: Can be used in a wide range of materials such as stainless steel, aluminum, brass and hard plastics.
Fast and Efficient: It can operate at high speed in mass production processes.
Easy Automation: Can be integrated into CNC machines and robotic systems.
How Dot Peen Marking Works
Dot peen marking machines work on the principle of piercing or indenting the surface using pneumatic or electromagnetic needles. The process takes place in the following steps:
Data Input: The content to be marked is entered into the machine via computer or control panel.
Material Selection: The surface to be treated is determined.
Marking Start: The machine applies strokes according to a predetermined template.
Quality Control: After the process is completed, the marking accuracy is checked.
Types of Dot Peen Marking
1. Pneumatic Dot Peen Marking
This system uses an air-pressurized needle mechanism and can mark at high speed. It is widely preferred in the automotive, aerospace and metalworking industries.
2. Electromagnetic Dot Peen Marking
It moves the needle using electromagnetic coils. It is suitable for more precise marking and has a low noise level.
3. Portable Dot Peen Marking
Developed for use on large or unstable parts. Common in construction sites, pipe production and heavy industry sectors.
4. Desktop Dot Peen Marking
Ideal for small and medium-sized businesses. Thanks to its compact structure, it provides ease of use in narrow spaces.
What to Consider When Choosing a Dot Peen Marking Machine?
Material Compatibility: A model suitable for the hardness and structure of the material to be marked should be selected.
Marking Area: A machine with the appropriate table size should be preferred according to small or large scale marking needs.
Speed and Efficiency: For mass production, high-speed models should be selected.
Software Compatibility: CAD/CAM supported systems provide advantages in terms of integration.
Ease of Maintenance: Durable and low-maintenance machines offer cost advantages in the long run.
Dot Peen Marking Uses
Automotive Industry: Used for marking part numbers, chassis numbers and serial numbers.
Aviation Industry: Ensures traceability of engine and aircraft components.
Medical Devices: Permanent marking on stainless steel surgical instruments.
Metal Processing Industry: Marking is applied on metal sheets, pipes and aluminum materials.
Defense Industry: Enables the serial numbers of military equipment to be made permanent.
Prices of Dot Peen Marking Machines
