What is Part Marking?
Part marking is the process of adding permanent or semi-permanent identification marks to components for traceability, branding, and quality control. These markings can include serial numbers, barcodes, QR codes, logos, or regulatory information.
In CNC machining and manufacturing, part marking is typically applied using laser engraving, chemical etching, or mechanical marking methods. The goal is to create clear, durable marks that remain legible throughout the product’s lifecycle without affecting part performance.
About Part Marking Service
We offer multiple part marking technologies to meet different application needs, from permanent industrial identification to high-contrast branding. Each method is selected based on material, durability requirements, and visual appearance.
CNC Engraving
CNC engraving is a mechanical marking process that removes material from the surface to create deep, permanent markings. It is widely used for industrial parts requiring long-term durability and clear identification.
Laser Engraving
Laser engraving uses focused laser beams to mark the surface with high precision and fine detail. It is ideal for complex graphics, logos, and data-rich codes, delivering clean and high-contrast results. :contentReference[oaicite:0]{index=0}
Silkscreen Printing
Silkscreen printing applies ink through a stencil onto the part surface, creating clear and visually strong markings such as logos and labels. It is commonly used for cosmetic marking on finished parts. :contentReference[oaicite:1]{index=1}

Part Marking FAQs
Common questions about CNC part marking methods, materials, and applications.
What is the best method for permanent part marking?
Laser engraving and CNC engraving are the most commonly used methods for permanent marking. Laser marking provides high precision and clean detail, while CNC engraving creates deeper, more wear-resistant marks for harsh environments.
Can you mark both metal and plastic parts?
Yes, we support part marking on a wide range of materials including aluminum, stainless steel, brass, copper, and engineering plastics. The marking method is selected based on the material and required finish.
Will part marking affect tolerances or part performance?
In most cases, marking has minimal impact on tolerances and functionality. Laser marking is a non-contact process, while CNC engraving can be controlled to ensure depth does not affect critical dimensions.
What types of markings can you create?
We can apply serial numbers, QR codes, barcodes, logos, text, and UID markings. Custom layouts and data-driven marking are also supported for traceability and branding.
Is part marking suitable for high-volume production?
Yes, both laser marking and silkscreen printing are highly efficient for batch production. We can integrate marking into the production workflow to improve efficiency and consistency.
Do you offer custom marking based on drawings or CAD files?
Absolutely. You can provide drawings, CAD files, or artwork, and we will ensure accurate placement, size, and formatting of all markings according to your specifications.
