When you need to mark plastic parts with a laser, there are a few things you need to know in order to get the perfect results every time. In this article, we will discuss the best ways to achieve optimal results when marking plastics with a laser.
What is Laser Marking?
Laser marking is the process of using a laser to create markings or images on a surface. The laser beam is focused onto the surface and causes the material to change color, resulting in a permanent mark.
How Does Laser Marking Work?
The laser marking process begins with the selection of the right laser for the job. There are many different types of lasers available, each with its own set of advantages and disadvantages. Once the correct laser has been selected, it’s mounted into a machine known as a laser marker. The marker then sends energy to the laser, which emits light that is directed at the part being marked. The light hits the surface of the part and creates a mark by melting or vaporizing the material.
How Does Laser Marking Work on Plastic Parts?
The laser marking process works best on plastic parts that have been cleaned and degreased thoroughly. The laser beam will vaporize any contaminants on the surface of the part, which could cause unwanted marks or smudges. Once the part has been properly cleaned, the laser marker will apply a series of dots or lines to the surface, depending on the desired result. The markings will be clear and easy to read, and they will not fade or wear off over time.
First, it is important to understand the different types of plastics and their properties. Some plastics are more difficult to mark than others, and some require specific settings on the laser machine in order to produce clear markings. Here is a brief overview of some of the most common types of plastic:
ABS (Acrylonitrile Butadiene Styrene) – ABS is one of the most popular types of plastic for use in manufacturing. It is strong and durable, and can be easily machined and formed. ABS is a good choice for laser marking because it produces a clean, dark mark that is easy to read.
PVC (Polyvinyl Chloride) – PVC is another common type of plastic that is often used in manufacturing applications. Like ABS, PVC produces a dark mark that is easy to read. However, it should not be used to mark materials that will come into contact with food or drink, as the markings may contain harmful chemicals.
PET (Polyethylene Terephthalate) – PET is a versatile plastic that can be used for a variety of purposes, including food packaging and beverage containers. It is also commonly used for laser marking because it produces clear markings with minimal distortion.
PP (Polypropylene) – PP is a strong, durable plastic that is widely used in manufacturing applications. Like ABS and PVC, it produces a dark mark that is easy to read.
Once you have determined which type of plastic you are marking, you need to set the laser machine for the correct settings. Each type of plastic has unique properties that require different settings on the laser machine in order to produce clear markings. Here are some general guidelines for setting the laser machine:
ABS – Set the power level to between 50-70%, and use a speed of 500-800mm/s.
PVC – Set the power level to between 50-70%, and use a speed of 500-800mm/s.
PET – Set the power level to between 30-50%, and use a speed of 400-600mm/s.
PP – Set the power level to between 50-70%, and use a speed of 700-1000mm/s.
Once you have set the laser machine for the correct settings, it is important to test them on a sample piece of plastic to ensure that they are correct. Always test the markings on a small piece of plastic before marking the entire part, as incorrect settings can cause damage to the plastic or produce poor quality markings.
