laser marking nylon

In this section, you will find applications in a wide variety of industries as well as detailed examples showing the advantages in using laser markers. Foaming works on all polymers, but also on some metals. Marking provides a print-like finishing on designs and other surfaces that cannot be erased. Conventional scanning methods only allow control from the X and Y axes, meaning the light could only be scanned on a flat surface. Laser-based colouration can be divided into four main principles. The molecules are condensed and the colour changes to a darker colour. Irradiate a plastic target with a laser to develop a color in the target itself. Laser marking with colour change is basically an electrical process, which reorders the macromolecules (changing their direction). Masking enables high-speed, high-resolution marking, but masks that match the content being marked must be prepared. A great diversity of plastics are being deployed especially in the automotive or medical industry. Laser marking is used for marking logos, product names, serial numbers, model numbers, and other information onto a product by irradiating the target with a laser light to melt, scorch, peel, oxidise, cut, or discolour the surface. This has resulted in an increase in scanning systems that allow for a higher degree of freedom. Recently, marking applications with various types have become common, and the high-speed capabilities of scanning lasers help cover weaker aspects of production. The laser radiation changes the crystal structure of the ions and the hydration level in the crystal. The “pigment” elements in the base material always contain metallic ions. When the base material absorbs the laser energy, the thermal effect increases the molecular density. Many plastics and thermoplastics can be laser marked. The laser works with a maximum pulse rate, but low energy per pulse. This is a must-read if you want to check the laser lineup first! This makes laser marking the preferred option for marks that need to remain legible even after several years, such as part numbers and serial numbers. Degree of depth is the primary distinguishing factor. Direct ink printing puts an image on the surface of the plastic which can be removed by abrasion or solvents, but Laser marking can provide an indelible high-contrast mark in the material itself, with no direct contact with the plastic other than through the incident Laser beam. Learn About Plastic Engraving Machines CO2 Laser Marking Machine: Rliable, cost-effective performance and high-quality marking for plastics and a wide range of other materials. Laser marking: The laser beam acts by decoloring the heated surface (clear marking on dark plastic or grey or black marking on clear material). (Example) Wide-area marking on LSI. Laser Marking Plastics? Today’s laser markers, however, can control the Z-axis height using a scanning mirror, making it possible to mark a wide variety of targets with various shapes. This method is generally referred to as engraving. These bubbles are particularly visible with darker base materials and result in “thin” colouration. Consequently, the composition of the element itself changes chemically, resulting in colour development due to the increased intensity of the pigment. This method provides contrast against the base material colour by peeling the paint, printed surface, or plating layers of a target for marking. Irradiation from the laser light results in a highly visible white colour on the surface of the plastic. Laser-based marking is performed as follows. Many plastics and thermoplastics can be laser marked. along with other resins for marking with variety of different lasers like 1064 nm Nd:YAG-Laser, fiber laser and solid state lasers. Laser markers can be used to perform various marking tasks, including the following. Topics: Based on the nature of the plastic, its functional purpose and its intended use the requirements for its marking are varying. All Rights Reserved. All Rights Reserved. It introduces marking examples and the optimal laser markers for a variety of materials such as ABS, epoxy, and PET. Depending on the material structure and size, different laser sources (e. g. fiber lasers) or laser machines (e. g. galvo lasers) can be used to further increase the speed. The types of laser used and some practical examples of laser processing. Should a plastic’s properties mean that it cannot be laser marked, it can usually … Use the heat of laser radiation to weld and join plastic parts. Carbonizing on the other hand enables strong contrasts on bright surfaces. Check out our 2020 buyer's guide to the top 10 laser marking machines. Learn all about basic laser topics such as oscillation principles and characteristics according to wavelength. White paper "Plastic laser marking" Based on the properties of a plastic, its functional purpose and its intended use the requirements for marking it are varying. This behaviour is also used in the laser welding of plastics, during which one welding partner absorbs the laser beam and the other welding partner is transparent for the laser beam. It introduces marking examples and the optimal laser markers for a variety of materials such as ABS, epoxy, and PET. The types of laser used and some practical examples of laser processing. Laser Marking for Other Materials (Glass / Paper / Ceramics / Other), Laser Marking for 2D Codes (Data matrix / QR Code / Barcode), Process Improvements from Mould Machining. The available types of lasers—such as CO2 lasers, YVO4 lasers, and YAG lasers—depends on the target material and the desired marking method. Laser Cut Nylon Services Nylon is a man-made synthetic fiber that is known for its elasticity and strength. Marking provides a print-like finishing on designs and other surfaces that cannot be erased. No material is removed, but some foaming is possible. When an area continuously receives high energy, macromolecules of the element around the base material are carbonised and turn black. The laser process terms “laser marking”, “laser etching”, “laser engraving” are often interchanged, however the technical aspects have important distinctions. Utilising high-output laser light, laser markers are capable of high-speed marking for efficient production. Should a plastic’s properties dictate that it cannot be laser … Markings are white and clear, making for an ideal replacement for stamps, labels, and printing. These bubbles are particularly visible with darker base materials and result in “thin” colouration. Our laser marking additives can be used in polyolefins like PP, HDPE, PS, ABS, PC, TPU, PET, PBT, Nylon, PVC and TPE etc. The highly visible, print-like finishing does not disappear like ink. Laser marking is a non-contact optical process in which the plastic has to absorb the laser beam. The laser radiation changes the crystal structure of the ions and the hydration level in the crystal. Generally, the fiber laser generates a white mark on any plastic base color. You are looking for a high-quality plastic mark. Laser markers can be roughly divided into two types: masking laser markers and scanning laser markers. This site is managed by KEYENCE CORP. This is a must-read if you want to check the laser lineup first! In this section, you will find applications in a wide variety of industries as well as detailed examples showing the advantages in using laser markers. You will surely find a suitable laser for your product making.

Copyright (C) 2021 KEYENCE CORPORATION. Consequently, the composition of the element itself changes chemically, resulting in colour development due to the increased intensity of the pigment. Laser marking is fundamentally different from ink printing, the traditional method of marking on plastics. This page shows some applications and information of laser processing. Laser engraving has replaced conventional two-part injection molding and rotary engraving as the preferred method for rapid production of custom day-and-night marks because of its speed, operational flexibility, and mark quality. Laser Marking Basics is designed to learn about laser marking applications and includes information on laser principles, types, and marking. Laser marking causes physical and chemical changes on the surface of the plastic, thus causing marks that are more permanent than standard ink printing or etching. Remove/engrave the surface layer with a laser. By using laser radiation to develop a color instead of engraving the plastic, damage from marking the target is minimized. The markings produced in laser marking operations contrast with the material surface, making them easy for both humans and machines to read. This is due to the fact that - compared to conventional marking procedures - no templates or consumables such as ink are required. Lasers can be used for a variety of marking methods including surface melting and scorching, plating and paint peeling, oxidisation, and discolouration.
