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.
CNC Engraving
CNC engraving is a mechanical marking process that removes material to create deep, durable markings for long-term industrial identification.
Laser Engraving
Laser engraving uses focused beams to create high-precision, high-contrast markings ideal for logos, graphics, and detailed codes.
Silkscreen Printing
Silkscreen printing applies ink onto surfaces for clear and visually strong markings, commonly used for branding and cosmetic finishes.

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.
Will part marking affect tolerances or part performance?
Marking typically has minimal impact. Laser marking is non-contact, while CNC engraving can be precisely controlled to avoid critical dimensions.
What types of markings can you create?
We support serial numbers, QR codes, barcodes, logos, text, and UID markings for traceability and branding.
Is part marking suitable for high-volume production?
Yes, laser marking and printing methods are efficient for batch production and can be integrated into manufacturing workflows.
Do you offer custom marking based on CAD files?
Yes, we can apply markings based on drawings or CAD files with precise positioning and formatting.
