Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.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).
Compressed air is not required.

In China, for the 3 million forklift trucks, there are a lot of fatal accidents such as blind spots, fatigue, speeding, squats, collisions, roller compaction, and crashes caused by steering. It caused serious consequences such as suspension of production lines, massive compensation, and leadership accountability. How can forklifts effectively prevent people/vehicles/cargo from colliding with forklift trucks? The following is an example of a forklift collision accident that took place in Shagang Group in 2003. 
(I) Accident Overview On February 4, 2003, Jiangsu Suzhou Shagang Group North Runzhong Company's three-shift workshop Class B forklift gongao XX shipped two bundles of wire rods (weight 4.9 tons) to the outside of the workshop for stacking. When the door left turned on the factory road, two guards patrolling on bikes were struck by a forklift and died on their way to the hospital. The direct economic loss is 300,000 yuan.
The device has a weight of 8000kg, a weight of 11310kg, and a lifting height of 4000mm. It is a wheel-type self-use machine. The car lighting system, brake system, steering system and other requirements are in line with the requirements. Untested and registered.
(2) Analysis of the causes of the accident 1. The direct cause is that the driver is paralysed by the night driving operation and is blindly observing the traffic conditions of the roads on the factory site and blindly driving.
2. The guards patrolled the bike at night. It was also a reason that the work area did not run on the right side of the road.
3. Because the light of the workshop is strong, the light of the stacking yard is not very bright, and the forklift moves out of the workshop. The contrast of light also has a certain impact on the eyesight of the driver.
4. Management is not in place and safety education is not targeted.
(III) Measures to Prevent Similar Incidents 1. The use unit shall formulate relevant management systems and operating procedures to strengthen the safety management of vehicles.
2. To strengthen the safety education for all employees, in particular to strengthen the training and management of special equipment operators to ensure that the drivers of the plant and trucks hold special equipment operator certificates.
3. The in-use motor vehicle must be inspected and registered, and obtain the license of the motor vehicle in the factory and the safety inspection qualified mark before it can be put into use.
In fact, many manufacturers are implementing the above measures, but the most effective and most secure is the fourth point proposed below:
4. Install wireless ranging anti-collision alarm:
Precise Distance Limit and Proximity Reminder are Collision Avoidance Keys Using the Wireless Ranging Collision Avoidance Alarm System, Shenzhen Weichuang Safety Technology Co., Ltd. develops a vehicle personnel wireless ranging alarm collision avoidance solution by real-time monitoring of a fixed micro base station on a large factory vehicle. The relative distance of the label within a ten meter radius is 10 centimeters. According to the distance, judging the degree of danger, different levels of sound and light alarms are made to effectively prevent and prevent high-risk accidents such as vehicle collisions and crushing of employees. 
Equipment installation diagram 
The wireless ranging anti-collision alarm system protects the forklift from collision with people, vehicles and goods through wireless ranging sensors to effectively reduce the occurrence of safety accidents in the factory and reduce economic losses and casualties. The wireless ranging collision avoidance alarm system can be used in forklifts, excavators, cranes, loading vehicles, bulldozers, industrial power vehicles, and the like, and is widely used in factories, construction sites, docks, and hazardous work areas, particularly in the operation of large machines. On the construction site, the safety of people, vehicles and things is guaranteed.
Notable Characteristics:
Cost effective
Requires no consumables
High speed accuracy
Will mark any material (including hardened steel)
Analysis of forklift collision accidents, how to effectively prevent the forklift from colliding with people/cars/cargo
According to statistics from OSHA of the U.S. Occupational Safety and Health Administration in 2013, 85 persons in North America were killed by a forklift accident, 34,900 were seriously injured due to a forklift accident, and 6,1800 were slightly injured due to a forklift accident. Under U.S. high-pressure inspection in the United States, there are still a large number of forklift accidents in the United States.
