Dot peening is one of the most common marking systems used industrially for projects that call for deep and permanent marks. For example, it is a favorite in the gas cylinder marking for product identification and traceability.
Like any marking system, many people, whether operators or clients, make many mistakes regarding the process. Below are a few mistakes you can make when using dot peen and how you can avoid making them.
Mistake 1: Using the Wrong Pin Marking Method
The most common mistake people make when using dot peening is using it when it is not the right method. This is a common trend when choosing between pin marking systems such as scribing peening. Using the wrong pin marking method won’t give you the desired result.
To understand when to use dot peen from similar methods, you need to understand what each one stands for. Below is their comparison
· Dot peen
It involves using a pen or stylus to impact a material to create a mark and is suitable when the project requires depth, speed, and permanent marking. The mark has a specific dot pattern that is highly readable.
Or manual engraving involves dragging the stylus on the material to create a smooth continuous mark. It is suitable for high-quality marks. Also, unlike dot peening, it does not produce much noise.
Both methods are suitable depending on the need for speed and quality markings. Therefore, the best bet is to talk to a marking expert to help you select.
Mistake 2: Missing Important Maintenance Checks
Maintenance checks are important as they allow the machine to function for a long time without a problem. Constant maintenance is necessary and it includes general cleaning and lubrication of moving parts.
Maintenance depends on the machine. Nevertheless, it is a critical part of the marking system for longevity. Therefore, you should ensure that operators have the dot peen machine’s manual and they understand it fully.
Mistake 3: Overlooking Laser Marking
Most manufacturers rely on dot peen without checking the capability of other marking systems. Laser marking is the most popular system used industrially due to its accuracy, speed, and productivity.
Choosing a laser marking machine depends on several factors considering the many types of lasers marking machines available on the market. However, when choosing one, ensures it fulfills the following:
- It is compatible with the material you are working with
- It does not take up too much space
- It does not require too much excessive training to master
There are many laser marking machines you can choose from concerning power, speed, and other factors. You can talk to our experts that will direct you to the best suited for your project.
Mistake 4: Not Taking Control of Your Controller
The dot peen machine controller is the brain of the operation. It is responsible for instructing the machine on what and how to mark. For example, it controls the depth, speed, font type, and other information manufacturers need to know.
Taking control of the pin marking controller means understanding how it works and how you can use it to the maximum capability. Aside from that, you should be able to consider the following things
- The need for proper training to understand how the controller works
- How to troubleshoot the controller
- How to know if the firmware is up to date
Understanding the following consideration allows you to take control and avoid mistakes in the future
Mistake 5: Features of the Dot Peen Machine
Many manufacturers also choose a dot peening machine without considering the capability, speed, and other factors. There are many types of dot peen machines in the market, and your choice should be based on their characteristics and functions. Study the different types and how they can better suit your project.
Mistake 6: Setting a wrong standoff distance
The standoff distance is the distance between the stylus or pin and the workpiece. It is important in determining the part’s depth, cleanliness, productivity, and overall quality.
Every dot peen machine has its device to adjust distance; however, you can tweak it to control the depth and improve the quality of the markings age should come with your machine when you purchase it. Ensure you use a test material to set the right standoff gage for your machine.
Mistake 7: Exceeding the maximum noise level
Dot peening can be very noisy depending on the material and product you are working on. OSHA requires that employees are not exposed to equal to or greater than 85 decibels averaged of noise over 8 hours of work. Not following this instruction can lead to stress, headaches, and in extreme cases, permanent hearing loss.
You can avoid this by keeping up with OSHA guidelines on reducing noise levels or working in such conditions. Also, you can use other methods such as scribing and laser marking, which are quieter and encompass the same properties. Laser marking also has contrast which aids in better readability.
Mistake 8: Material Compatibility
Dot peening machines are not suitable for all materials. The machines are only suitable for some hard objects or objects compatible with the method’s mechanical stress. For example, metals and hard plastics.
Using the dot peening machine for other types of material is wrong. Instead, you should consider other marking systems.
Reduce Future Dot Peen Mistakes
You need to understand the dot peening marking system to avoid the different mistakes. This includes the properties, material compatibility, types of machines, and applications. Afterward, it would help if you had the right plan. The right plan involves working with your team to review past or potential issues and how to prevent them.
The most important way to reduce future dot peen mistakes is to get the best dot peen machine. Get a dot peen marking machine partner with enough experience to advise you on using the machines.
