History of Marking Machinery

Humans have been marking items since long before the advent of modern machinery. One of the earliest examples of engraving dates back between 430,000 and 540,000 years ago, seen in a chiseled shell discovered in Indonesia. Following this discovery, the next oldest artifacts found are ostrich shells with engraved bandings, likely created around 60,000 BC, found at the Diepkloof Rock Shelter in South Africa. These shells were likely used by early humans as containers or cups for water. During the Upper Paleolithic period, which spanned from about 50,000 to 10,000 years ago, humans globally began engraving ivory and bone with depictions that reflected their daily lives and cultures.

Around the 1st Millennium BC, humans started metal marking using techniques like lost-wax casting and chasing, allowing for shallow grooves. It was during this period that they also began engraving gemstones for jewelry and decorative purposes.

During the early 1600s, Jacque Callot, a French printmaker, revolutionized the art of etching with his invention of the échoppe, an etching needle distinguished by its slanted oval point. This innovation enabled metalworkers and artists to replicate the bold, swelling lines typically reserved for engraving techniques.

During the 20th century, governments globally aimed to streamline markets and establish uniform standards for labeling machinery. For instance, in 1984, the European Union introduced the CE mark. Short for Conformité Européenne (European Conformity), this mark visibly identifies products and equipment that meet specified standards. Similarly, countries like the United States and Canada developed their own conformity marks, aligning with and adapting the principles of the CE mark.

Since then, marking technologies have advanced significantly. Today, they play a crucial role in creating intricate electronic markings. While handcrafted engraving and etching persists, CNC machinery largely dominates these tasks due to its precision and efficiency.

Types of Marking Machinery

Marking systems encompass a variety of machines designed to emboss, etch, stamp, or print designs onto diverse surfaces. These systems utilize a range of techniques and tools , including laser markers, press markers, dot peen machines, and nameplate markers. Additionally, they incorporate other specialized equipment such as embossing machines, engraving machines, roll or rotary marking devices, hot stamping machines, numbering machines, and etching machines.

Press markers, also known as presses, excel at creating rapid, enduring marks. However, they lack flexibility and require considerable setup time. Moreover, they are unsuitable for hard or fragile materials and can pose operational hazards.

Dot peen machines, alternatively called dot marking or pin mark machines, utilize a micro-percussion marking system to imprint objects with a series of closely spaced dots. This method employs a tapping pin for fast and precise marking, ensuring minimal stress on the substrate without material removal.

Nameplate markers, aptly named for their purpose, are tools utilized for imprinting or etching nameplates. Typically, these are employed for metal nameplates positioned on desks or displayed outside office spaces.

Embossing machines utilize heat and pressure to impress a three-dimensional image onto ductile materials such as plastic and leather. This process permanently deforms the material’s surface, imprinting product information. Credit cards, for instance, display raised numbers and letters through this method.

Engraving machines, designed to cut intricate grooves, excel particularly on tough materials such as metals, making them ideal for crafting jewelry.

Roll marking equipment employs cylindrical dies that are rolled physically onto the product for marking purposes. It offers a cost-effective alternative compared to equipment designed for high tonnage operations.

Hot stamp presses involve several key components: a stamping foil, a heated plate, and a metallic stamp or die. In operation, manufacturers heat the metallic stamp using the hot plate, then apply both the stamp and the foil onto the surface of the part intended for marking.

Hand stamping, performed manually, is a cost-effective and straightforward process that doesn’t necessitate costly equipment or highly skilled operators. However, it is labor-intensive and prone to inconsistencies.

Numbering machines are specialized marking devices designed to imprint sequential numbers onto papers, typically utilized for the purpose of legal documentation.

Printing machines serve the additional purpose of marking flat surfaces, typically using ink to create marks.

Industrial inkjet printers represent a larger-scale iteration of their household and office counterparts. They boast significantly faster printing speeds compared to various other marking technologies, yet their reliance on impermanent inks poses environmental hazards.

Pad printing machines enable the printing of 2D marks on 3D products by utilizing silicone pads to transfer images from a printing plate onto the product’s surface. They are commonly purchased by customers in industries such as electronics, toys, and medical equipment marking.

Chemical etching utilizes corrosive acids or bases to selectively remove material from a surface. The process typically includes five key stages: cleaning the surface, applying a mask, marking or scribing the desired pattern, etching to dissolve the exposed areas, and finally removing the mask. While cost-effective, chemical etching can yield inconsistent results, making it more suitable for less precision-critical applications or materials.

Plasma etching falls into two main categories: vacuum and normal-pressure types. Vacuum plasma, the more prevalent method, creates plasma from gasses like oxygen under reduced pressure to activate molding surfaces. While highly effective for surface modification, it operates in batches and prolonged processing times can degrade moldings.

Laser marking utilizes a powerful beam of laser radiation, typically from a fiber laser, to directly imprint materials’ surfaces. The process categorizes laser markers based on beam wavelength, tailored to the material’s properties and responsiveness to laser energy. This technology engraves or etches designs permanently by focusing a concentrated light beam onto the material, ensuring lasting impressions that do not fade over time like ink or dyes. Automated modern machines facilitate its application for writing text, barcodes, or graphics on various materials.

How Does Laser Marking Work?

The laser, utilizing light amplification by stimulated emission of radiation, targets a surface directly. Through interaction with the material, the laser alters its properties, thereby causing noticeable changes to the surface appearance. The laser targets a precise section of the surface needing marking. Suitable materials encompass metals, plastics, foils, films, paints, and more. Marking techniques range from annealing and staining to foaming, engraving, and removal.

Types of Laser Marking Machines

Laser marking is achieved using specialized machines designed for the purpose. These machines utilize specific wavelengths of laser light tailored to different materials for effective marking.

Following are the three major types:

Fiber laser marking machines employ 1090-nanometer infrared lasers, ideal for marking metals and metal products. Their infrared wavelength allows them to penetrate opaque surfaces, making them particularly effective for materials that are not transparent. These machines excel in tasks such as annealing and engraving metal.

UV laser marking utilizes ultraviolet rays at a precise wavelength of 355 nm. Ultraviolet (UV) light possesses high absorptive qualities, making it ideal for cold marking applications. This method is particularly suited for materials with high reflectance, such as gold and copper, or those sensitive to heat typically generated during conventional laser marking processes.

CO2 laser marking machines are employed for marking paper, resins, rubbers, as well as transparent materials such as glass and certain plastics. With a wavelength system ten times longer than conventional lasers, these machines are ideal for materials that normal lasers cannot effectively absorb, especially transparent ones.

Advantages of Laser Marking

Laser marking offers more than just durable, abrasion-resistant markings. It enables traceability, making it straightforward to track items once branded or identified. This method produces minimal waste and is efficient, creating clear, easily visible marks. By providing unique identification and traceability, it effectively reduces risks associated with counterfeiting.
