Laser Marking

Laser come out from the laser source and pass though the scan head and lens or other optical equipment then the surface of the material will be irradiated by focused laser beam. As a result, the color of the material surface changes.

Popular Laser Marking Industiral Uses & Applications

Brief Introduction

This pipe is usually made of PVC or PE. Why is laser marking required to replace ink printing code? Because the effect of laser marking is permanent. It is also usually required that the marking effect has a good contrast.

Key Point

1. High efficiency of flight marking is required (minimum speed 3000 mm/s).2. Precise heat control is critical during the marking process, to avoid the surface melting caused by excessive heat.

Parameters:

Laser Type: Seal-355-15; Lens: F254 Speed: 3000 - 5000 mm/s Pulse width: 9 us Cross Hatch: singlet line

Brief Introduction

ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. In the current ABS is often used in automotive trim components, kitchen appliance, musical instruments.

Key Point

Precise heat control is critical during the marking process, because too much heat input will cause the color of the marking effect to turn yellow.

Parameters:

Brief Introduction

IC, also known as a microcircuit, a microchip, or an integrated circuit, is a small piece of silicon containing an integrated circuit that is often part of a computer or other electronic device.

Key Point

The linewidth of laser marking could be smaller by using UV laser compared with fiber laser, because of shorter wavelength.

Parameters:

Laser Type: Seal-355-5; Lens: F100 Speed: 800 mm/s, Pulse width: 2-3 us Cross Hatch: Single line Line width: 19-23 μm

Brief Introduction

Stainless steel is a corrosion resistant ferroalloy with a minimum chromium content of about 11%. It can be used for cookware, cutlery, decorations, surgical, construction material in large buildings, etc.

Key Point

1. JPT MOPA laser can achieve wide gray scale range.2. JPT MOPA laser has minimum delay time to make the first pulse useable.

Parameters:

Laser Type: YDFLP-20-M7 Lens: F254 Speed: 1000 mm/s Pulse width: 100-200 ns

Brief Introduction

Heat-Shrink tube, known as Heat Shrink, is widely used as a protective covering for capacitance(Fig.1a), electrical wires (Fig. 1b) and etc.

Key Point

1. Precise heat control is critical during the marking process, to avoid shrink of the tube because of the heat effect.2. High marking efficiency is essential for fly marking.

Brief Introduction

Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, etc.) as the main raw materials. In addition, glass is widely used in architecture, art, electronics, and other fields.

Key Point

Precise power control is critical during the marking process, to avoid glass breakage due to the heat effect.
